Abstract and Figures

In 2017, the International Waterbird Census (IWC) was carried out in Slovenia on January 14 and 15. Waterbirds were counted on all larger rivers, along the entire Slovenian Coastland and on most of the major standing waters in the country. During the census, in which 235 observers took part, 413 sections of the rivers and coastal sea with a total length of 1,427 km and 200 other localities (164 standing waters and 36 streams) were surveyed. The census was characterized by harsh winter conditions and high proportion of frozen water bodies. Altogether, 51,790 waterbirds of 61 species were counted. Thus, the number of waterbirds and the number of species recorded were close to the 21-year average. The highest numbers of waterbirds were counted in the Drava count area, i.e. 20,064 individuals (38.7% of all waterbirds in Slovenia). By far the most numerous species was Mallard Anas platyrhynchos (46.1% of all waterbirds), followed by Coot Fulica atra (6.8% of all waterbirds), Cormorant Phalacrocorax carbo (5.9% of all waterbirds), Black-headed Gull Chroicocephalus ridibundus (5.7% of all waterbirds) and Mute Swan Cygnus olor (3.9% of all waterbirds). The number of 1,000 counted individuals was also surpassed by Yellow-legged Gull Larus michahellis , Teal An. crecca , Tufted Duck Aythya fuligula , White-fronted Goose Anser albifrons , Pygmy Cormorant P. pygmeus and Grey Heron Ardea cinerea . Among the rarer recorded species, the Red-breasted Goose Branta ruficollis (registered for the first time during the January Waterbird Censuses and only for the third time ever in Slovenia) and Barnacle Goose Branta leucopsis (the first probable A category individual for IWC and Slovenia) deserve special mention. Numbers of the following species were the highest so far recorded during the IWC: Mandarin Duck Aix galericulata (together with 2006 and 2012), Pintail An. acuta , Ferruginous Duck Ay. nyroca , Long-tailed Duck Clangula hyemalis (together with 2003), Goosander Mergus merganser , Pygmy Cormorant, Herring Gull L. argentatus and Caspian Gull L. cachinnans . Number of Pochards Ay. ferina was the lowest so far recorded during the IWC.

Januarsko štetje vodnih ptic (IWC) poteka v
Sloveniji od leta 1988, leta 1997 pa je bilo prvič
zastavljeno kot celosten, koordiniran in standardi-
ziran popis vodni h ptic na ozemlju celotne Slovenije
(Š 1997). Od takrat naprej štetje
pokriva vse večje reke, Obalo in večino pomemb-
nejših stoječih vodnih teles v državi (Š
1997, 1998, 1999, 2000, 2001, 2002, 2005, B
2005, 2006, 2007, 2008a, b, 2010, 2011, 2012,
2013, 2014, 2015, 2016). K temu sta pripomogla
predvsem dobra organizacija in veliko število
sodelujočih prostovoljnih popisovalcev. Vporočilu
so predstavljeni rezultati januarskega štetja vodnih
ptic leta 2017, ki je v podobnem obsegu potekalo že
enaindvajsetič zapored.
Leta 2017 smo vodne ptice šteli 14. in 15.
januarja. Organizacija, potek, uporabljena metoda
štetja in popisni obrazci so bili takšni kot leta 1997
(Š 1997). Pri obdelavi in predstavitvi
rezultatov smo upoštevali tudi nekatere podatke,
zbrane zunaj organiziranega štetja, vendar
največ do sedem dni pred ali po koncu tedna,
predvidenega za štetje. Kormorane Phalacrocorax
carbo smo na števnih območjih Mure, Drave in
Savinje sistematično posebej šteli na znanih in
domnevnih skupinskih prenočiščih. Na skupinskih
prenočiščih smo šteli tudi pritlikave kormorane
P. pygmeus, zvonce Bucephala clangula velike
žagarje Mergus merganser in galebe Laridae na
števnem območju Drave. Mokože Rallus aquaticus
smo na ptujskih studenčnicah in potoku Črnec
(Murska ravan) sočasno s štetjem drugih vodnih
ptic popisali ob pomoči predvajanja posnetka
oglašanja. Metoda je podrobneje opisana v B
(2002). Vštetje so bile ta ko kot vsako leto vključene
vrste iz naslednjih skupin ptic: plovci Anatidae,
slapniki Gaviidae, kormorani Phalacrocoracidae,
čaplje Ardeidae, štorklje Ciconiidae, plamenci
Phoenicopteridae, ponirki Podicipedidae, tukalice
Ral lidae, pobrežnik i Charadriiformes ter belorepec
Haliaeetus albicilla, rjavi lunj Circus aeruginosus,
močvirska uharica Asio ammeus, vodomec Alcedo
atthis in povodni kos Cinclus cinclus.
Januar 2017 je bil najhladnejši v nekaj zadnjih
desetletjih. Povprečna mesečna temperatura je bila
povsod občutno nižja od dolgoletnega povprečja.
V večjem delu zahodne Slovenije in Gorenjske je
bil januar do 3°C hladnejši kot običajno. Drugod
po državi je bil odklon še večji, del Dolenjske in
Štajerske je bil 4 do 5 °C hladnejši od povprečja
primerjalnega obdobja. V nižinskem svetu se je
temperatura spustila najnižje med 7. in 11. 1., ko
so marsikje v notranjosti Slovenije izmerili okoli
–20°C, na Primorskem in Obali pa okoli –10°C.
Neposredno pred štetjem je izrazito mrzlo obdobje
12. in 13. 1. prekinila kratkotrajna otoplitev, ki
pa so ji spet sledili mrzli dnevi. Takrat je tudi
padla večina padavin sicer zelo suhega meseca, v
katerem je v večjem delu države padlo le 40–80%
padavin dolgoletnega povprečja. Primanjkljaj je bil
največji v Zgornjem Posočju, najmanjši pa v delu
jugovzhodne Slovenije. V omenjenem obdobju je
po nižinah v notranjosti Slovenije zapadlo 5–20
cm snega, ki se je potem zaradi mrzlega vremena
obdržal. Januar 2017 je bil občutno hladnejši od
dolgoletnega povprečja tudi v večjem delu Evrope,
še posebej na jugovzhodu celine. December 2016
je bil v nižinah pretežnega dela države hladnejši
kot običajno, s temperaturnimi odkloni večinoma
med −2 in 0°C. V severozahodni Sloveniji je bil
ta mesec nadpovprečno topel, najbolj izrazito v
gorskem svetu (odklon do +3 °C). December je
minil tako rekoč brez padavin, saj večji del države
ni dobil niti 1% običajnih padavin, le na skrajnem
severovzhodu je bilo preseženih 15% dolgoletnega
povprečja (C 2016, 2017). Pretoki rek so bili
januarja povsod podpovprečni, pri čemer je bila
vodnatost velikih rek nekoliko večja. Podobne
razmere so bile tudi decembra (S 2016,
2017). V času štetja je bilo nad zahodno Evropo
območje visokega zračnega tlaka, drugi dan se je
nad osrednjim Sredozemljem poglobilo ciklonsko

(do 1/2), na srednji Savi pa nekaj krajših delov (do
1/2). Delno sta bili zaledeneli tudi Paka (do 1/2) in
Voglajna (3/4). Vsi pregledani odseki Sotle so bili
zaledeneli 1/2–3/4 oz. v celoti, nekaj odsekov Krke
v spodnjem delu reke pa do 1/4. Spodnji odsek
Reke je bil zaledenel 1/2. Izmed rečnih akumulacij
je led prekrival Ledavsko jezero (v celoti), Gajševsko
jezero na Ščavnici (3/4), Mariborsko, Ptujsko in
Ormoško jezero ter akumulacijo Melje na panonski
Dravi (>3/4), Perniško jezero in jezero Pristava na
Pesnici (v celoti), jezero HE Moste na zgornji Savi
(1/2), Trbojsko jezero (v celoti) in Zbiljsko jezero
(1/4) na srednji Savi ter akumulaciji HE Boštanj
(1/4) in HE Krško (>1/2) na spodnji Savi. Večina
stoječih vodnih teles v notranjosti Slovenije je bila
zaledenela v celoti, redka pa vsaj 3/4. Nezaledeneli
sta bili le dve veliki in globoki gramoznici na
števnem območju Mure. Škalsko jezero je bilo
zaledenelo v celoti, drugi dve šaleški jezeri 1/2,
Vonarsko jezero pa 3/4. Cerkniško jezero je bilo
suho (voda le v glavnih strugah) in zaledenelo
3/4. Soline in laguna Škocjanskega zatoka so bile
nezaledenele.
Sodelovalo je 235 popisovalcev. Pregledali smo
413 popisnih odsekov na rekah in obalnem morju
v skupni dolžini 1427km (tabela 1), kar je 78,0%
celotne dolžine odsekov, vključenih v popis. Poleg
tega smo pregledali tudi 200 lokalitet (164 stoječih
in 36 tekočih voda) od skupno 328 (tabela 2),
kar je 61,0% vseh lokalitet, evidentiranih v bazi
januarskega štetja vodnih ptic do vključno leta
2017. Popisne odseke, pregledane v štetju leta 2017,
prikazuje slika 1, razširjenost pregledanih lokalitet
pa slika 2.
Skupaj smo prešteli 51.790 vodnih ptic,
pripadajočih 61 vrstam. Poleg tega smo zabeležili
še šest drugih taksonov (domačo gos, domačo raco
in štiri vrstno nedoločene taksone). Skupno število
vodnih ptic je bilo blizu povprečnemu (51.446)
in nekoliko manjše kot v prejšnjem štetju. Tudi
število zabeleženih vrst je bilo blizu povprečnemu
(60). Tako kot običajno smo tudi leta 2017 največje
število vodnih ptic prešteli na števnem območju
reke Drave, in sicer 20.06 4. To je 38,7% vseh vodnih
ptic, preštetih v Sloveniji. Manjše šte vilo smo na tem
območju zabeležili v štirih štetjih pred tem in prav
tako v štirih štetjih je bil odstotek vodnih ptic na
tem območju manjši od 40%. Na števnem območju
Mure smo prešteli največ vodnih ptic v dosedanjih
januarskih štetjih. Med največjimi doslej je bilo
tudi število vodnih ptic na območju Savinje (več v
letih 2001 in 2002), občutno večje od povprečnega
pa še na območju Zgornje Save. Število vodnih
ptic je bilo blizu povprečnemu na Spodnji Savi. Na
števnih območjih Kolpe, Notranjske in Primorske
ter Obale so bila števila vodnih ptic občutno
manjša od povprečnega. Na slednjem se je s tem
število zaporednih štetij s podpovprečnim številom
vodnih ptic povečalo na pet. Na Notranjskem in
Primorskem je vzrok za takšen rezultat verjetno v
slabši pregledanosti vodnih teles na tem območju.
Ocenjujemo, da je obsežna zaledenelost vplivala
na število vodnih ptic na števnem območju Drave,
kjer je bilo zaradi tega pojava zlasti na Ptujskem
in Ormoškem jezeru preštetih občutno manj
ptic od povprečnega (3935 vs. 8244 in 3592 vs.
4723). Čeprav je bila večina stoječih vodnih teles
pod ledom, so se na nekaterih lokalitetah, zlasti v
SV Sloveniji, na zaledeneli površini ali skromnih
ostankih odprte vode zbrale velike skupine vodnih
ptic. Tako kot v večini štetij doslej tudi leta 2017
števila 10.000 preštetih vodnih ptic nismo presegli
na nobenem drugem števnem območju.
Mlakarica Anas platyrhynchos je bila leta 2017,
tako kot med vsemi štetji doslej, daleč najštevilnejša
vrsta (23.864 os., 46,1 % vseh vodnih ptic). Po
številu preštetih osebkov sledijo liska Fulica atra
(3543 os., 6,8 % vseh vodnih ptic), kormoran
(3078 os., 5,9 % vseh vodnih ptic), rečni galeb
Chroicocephalus ridibundus (2938 os., 5,7 % vseh
vodnih ptic) in labod grbec Cygnus olor (1995 os.,
3,9 % vseh vodnih ptic). Število 1000 preštetih
osebkov so leta 2017 presegli še rumenonogi
galeb Larus michahellis, kreheljc An. crecca,
čopasta črnica Aythya fuligula, beločela gos Anser
albions, pritlikavi kormoran in siva čaplja Ardea
cinerea. Beločela gos je omenjeno mejo presegla le
še leta 2013, ko je bila prav tako kot letos med 10
najštevilnejšimi zabeleženimi vrstami. Rezultati
januarskega štetja vodnih ptic leta 2017 po shemi
razdelitve na osem števnih območij (B 2007,
2008a, 2008b, 2010, 2011, 2012, 2013, 2014,
2015, 2016) so predstavljeni v tabeli 3. V dodatku
1 so števna območja podrobneje razčlenjena na
posamezne reke in manjša območja z večjim
številom lokalitet, kot so poplavne ravnice, doline,
ravnine ipd.

Leta 2017 smo prvič med januarskim štetjem
vodnih ptic zabeležili rdečevrato gos Branta
rucollis (Gajševsko jezero, Mura), kar je po zadnjem
opazovanju iz leta 2011 tretji podatek o pojavljanju
te vrste v Sloveniji. Opazovanje belolične gosi
B. leucopsis (Ormoško jezero, Drava) domnevno
izpolnjuje pogoje za uvrstitev v kategorijo A. Vsa
dosedanja opazovanja v Sloveniji so uvrščena v
skupino vrst, ki z veliko verjetnostjo izhajajo iz
ujetništva (kategorija E) oziroma vrst, za katere
obstaja utemeljen sum, da opazovani osebki niso
iz prostoživeče populacije (kategorija D) in niso
del seznama ugotovljenih ptic Slovenije (H
Š 2011, H 2016). Od redkejših vrst
smo popisali nilsko gos Alopochen aegyptiacus
(glinokop Volčja draga, Primorska; drugo
opazovanje v januarskem štetju vodnih ptic) in
pukleža Lymnocryptes minimus (Mlake, Vipavska
dolina; četrto opazovanje v januarskem štetju
vodnih ptic). Nevestico Aix sponsa smo zabeležili
šele drugič v zadnjih 12 štetjih, črnega martinca pa
prvič po štirih letih brez podatka. Leta 2017 smo
prešteli največ mandarink Aix galericulata (skupaj
z letoma 2006 in 2012), dolgorepih rac An. acuta,
kostanjevk Aythya nyroca, zimskih rac Clangula
hyemalis (skupaj z letom 2003), velikih žagarjev
Mergus merganser, pritlikavih kormoranov,
srebrnih galebov L. argentatus in črnomorskih
galebov L. cachinnans v okviru januarskih štetij
vodnih ptic doslej. Razen tega je bilo izmed vrst, ki
se pojavljajo redno, beločelih gosi več le med štetjem
leta 2013, sivih gosi Anser anser leta 2016, tatarskih
žvižgavk Netta runa pa leta 2012. Med največjimi
doslej so bila tudi števila preštetih labodov grbcev
Cygnus olor (večje le trikrat pred 2017), duplinskih
kozark Tadorna tadorna (večje le v letih 2011 in
2014), belolisk Melanitta fusca (večje le v letih 1997
in 2013), malih belih čapelj Egretta garzetta (večje
le v letih 2003 in 2015), belorepcev (večje samo
leta 2004, enako 2012 in 2016) in kričavih čiger
Sterna sandvicensis (večje le v letih 2006 in 2010).
Število črnovratih ponirkov Podiceps nigricollis je
bilo največje v zadnjih 10 štetjih. Najmanjše število
v enaindvajsetih letih januarskih štetij vodnih ptic
smo leta 2017 zabeležili pri sivki Aythya ferina.
Števila naslednjih vrst so bila med najmanjšimi
doslej: rac žličaric An. clypeata (najmanjše po letu
2008), lisk (manjše le v letu 2013), velikih škurhov
Numenius arquata (v zadnjih 16 štetjih manjše le
v letu 2016) in rečnih galebov (manjše le v letih
1998 in 2005). Od redno pojavljajočih se vrst
drugič zapored v štetju nismo zabeležili rdečegrlega
slapnika G. stellata in spremenljivega prodnika
Calidris alpina, medtem ko rdečenogega martinca
Tringa totanus ni bilo že četrtič zapored, priba
Vanellus vanellus pa je bila v zadnjih petih štetjih
popisana le dvakrat.
Podobno kot v zadnjem predhodnem štetju
s snežno odejo v nižinah (v Sloveniji in tudi širše
v Evropi) so se čez naše kraje v smeri od vzhoda
proti zahodu selile jate gosi, med katerimi so
prevladovale beločele in sive gosi. Tudi številčnost
nekaterih drugih vrst (relativno malo velikih belih
čapelj, veliko sivih galebov itd.) je bila podobna
kot v štetjih v zadnjem desetletju, ki so potekala v
razmerah nizkih temperatur in/ali snežne odeje v
nižinah (2009, 2010, 2013). Pri nekaterih vrstah z
največjimi ali velikimi zabeleženimi števili (labod
grbec, duplinska kozarka, dolgorepa raca, veliki
žagar, pritlikavi kormoran), kot tudi vrstah z
majhnimi števili (priba in zgoraj omenjene tri vrste
pobrežnikov iz družine kljunačev Scolopacidae),
so ta nadaljevanje dolgoročnih populacijskih
trendov njihovih januarskih populacij v Sloveniji
(B 2014, 2015, 2016). Leta 2017 smo tretjič
zapored in sedmič v zadnjih desetih štetjih prešteli
največje število velikih žagarjev, pri katerem so
bila prejšnja največja števila občutno presežena na
Zgornji Savi (+70,9%) in Spodnji Savi (+72,8%)
ter zmerno presežena na Savinji (+9,8 %), razen
tega pa je bila vrsta sploh prvič doslej prešteta
na števnem območju Obale. Kljub povečanju
številčnosti pritlikavega kormorana za več kot
enkrat v zad njih dveh štetjih, ta ostaja skoraj v celoti
omejen na reko Dravo, kjer se praktično celotna
prezimujoča populacija zbere na enem samem
prenočišču. V štetju leta 2017 so na posameznih
območjih tri vrste presegle mejno vrednost 1% za
opredeljevanje mokrišč mednarodnega pomena
(W I 2017). Beločela gos
(1 % regionalne populacije albions, Zahodne
Sibirije / Srednje Evrope) in pritlikavi kormoran
(4,3% črnomorsko-mediteranske populacije) sta to
vrednost presegla na SPA Drava SI5000011, veliki
žagar pa poleg Drave še na Savinji in Zgornji Savi

so bili veliki žagarji v večjem številu zabeleženi tudi
na vseh pomembnejših pritokih Save.
Streljanje vodnih ptic v času štetja je bilo
zabeleženo na nekateri h odsekih Mure, Ljubljanice,
Iščice, Spodnje Save, Kolpe in Vipave.
Zahvala
Vsem popisovalcem, ki so šteli vodne ptice, in
lokalnim koordinatorjem gre zasluga, da smo
ponovno in sistematično hkrati popisali vse
pomembnejše vodne površine v Sloveniji. Brez
nesebičnega truda to ne bi bilo mogoče. Vsem
najlepša hvala.

Summary
In 2017, the International Waterbird Census
(IWC) was carried out in Slovenia on January 14
and 15. Waterbirds were counted on all larger rivers,
along the entire Slovenian Coastland and on most
of the major standing waters in the country. During
the census, in which 235 observers took part, 413
sections of the rivers and coastal sea with a total
length of 1,427 km and 200 other localities (164
standing waters and 36 streams) were surveyed.
e census was characterized by harsh winter
conditions and high proportion of frozen water
bodies. Altogether, 51,790 waterbirds of 61 species
were counted. us, the number of waterbirds and
the number of species recorded were close to the
21-year average. e highest numbers of waterbirds
were counted in the Drava count area, i.e. 20,064
individuals (38.7% of all waterbirds in Slovenia).
By far the most numerous species was Mallard Anas
platyrhynchos (46.1% of all waterbirds), followed
by Coot Fulica atra (6.8% of all waterbirds),
Cormorant Phalacrocorax carbo (5.9% of all
waterbirds), Black-headed Gull Chroicocephalus
ridibundus (5.7% of all waterbirds) and Mute Swan
Cygnus olor (3.9% of all waterbirds). e number
of 1,000 counted individuals was also surpassed
by Yellow-legged Gull Larus michahellis, Teal An.
crecca, Tued Duck Aythya fuligula, White-front-
ed Goose Anser albions, Pygmy Cormorant P.
pygmeus and Grey Heron Ardea cinerea. Among
the rarer recorded species, the Red-breasted Goose
Branta rucollis (registered for the rst time during
the January Waterbird Censuses and only for the
third time ever in Slovenia) and Barnacle Goose
Branta leucopsis (the rst probable A category
individual for IWC and Slovenia) deserve special
mention. Numbers of the following species were
the highest so far recorded during the IWC:
Mandarin Duck Aix galericulata (together with
2006 and 2012), Pintail An. acuta, Ferruginous
Duck Ay. nyroca, Long-tailed Duck Clangula
hyemalis (together with 2003), Goosander Mergus
merganser, Pygmy Cormorant, Herring Gull
L. argentatus and Caspian Gull L. cachinnans.
Number of Pochards Ay. ferina was the lowest so
far recorded during the IWC.
Povzetek
Leta 2017 je zimsko štetje vodnih ptic (IWC) v
Sloveniji potekalo 14. in 15. januarja. Vodne ptice
smo prešteli na vseh večjih rekah, celotni slovenski
obali in na večini večjih vodnih teles v notranjosti
države. V popisu je 235 popisovalcev pregledalo
413 odsekov rek in obalnega morja v skupni dolžini
1427km in še 200 drugih lokalitet (164 vodnih
teles in 36 potokov). Popis so zaznamovale nizke
temperature in visok delež zamrznjenih vodnih
površin. Prešteli smo 51.790 osebkov 61 vrst.
Številki sta blizu 21-letnega povprečja. Največ
vodnih ptic je bilo preštetih na števnem območju
Drave, in sicer 20.064 (38,7% vseh vodnih ptic v
Sloveniji). Najštevilčnejša je bila mlakarica Anas
platyrhynchos (46,1% vseh vodnih ptic), sledijo ji
liska Fulica atra (6,8%), kormoran Phalacrocorax
carbo (5,9 %), rečni galeb Chroicocephalus
ridibundus (5,7 %) in labod grbec Cygnus olor
(3,9%). Več kot tisoč osebkov smo prešteli še pri
rumenonogem galebu Larus michahellis, kreheljcu
An. crecca, čopasti črnici Ay. fuligula, beločeli gosi
Anser albions, pritlikavem kormoranu P. pygmeus
in sivi čaplji Ardea cinerea. Med redkejšimi vrstami
izstopata rdečevrata gos Branta rucollis (pr vič med
IWC in tretjič nasploh) in belolična gos Branta
leucopsis (verjetno prvi podatek za kategorijo A v
Sloveniji). Za naslednje vrste smo našteli največje
število osebkov doslej v IWC: mandarinka Aix
galericulata (izenačenje z letoma 2006 in 2012),
dolgorepa raca An. acuta, kostanjevka Ay. nyroca,
zimska raca Clangula hyemalis (izenačenje z letom
2003), veliki žagar Mergus merganser, pritlikavi
kormoran, srebrni galeb Larus argentatus in
črnomorski galeb Larus cachinnans. Število sivk Ay.
ferina je bilo najnižje doslej.
Ključne besede: mokrišča, sivka Aythya ferina,
rdečevrata gos Branta rucollis
Key words: wetlands, Pochard Aythya ferina,

Although the Mallard is one of the most numerous and best-studied waterbirds in the world, it received almost no attention in Slovenia. It is one of the most frequently observed waterbirds in our country, with frequency often reaching 100%. Sites with lower frequency either freeze in winter or have a low number of individuals to start with. The Mallard is also the most dominant species (17.5% and 89.0%) with higher dominance at sites less suitable for waterbirds due to the lack of available shoals. Mallards reach their maximum numbers during fall migration and winter. Spring migration has no discernible peak and has been significant only for Lake Cerknica. On shallow waters, the maximum is reached in August and September, a month before fall migration begins, indicating local movement to food-rich sites. Females make up only 36.7% of the observed Mallards and reach the maximum proportion (41.5%) in winter and the lowest in April and May (14.7%), when they nest. The breeding season in Slovenia lasts from mid-January to early December, with the majority of females rearing broods from April to July. Average brood size is 6.2 ± 2.66 and declines with season, age of young and altitude. It varies between habitat types and is highest on Treatment and Coastal Wetlands (7.3) and lowest on deep waters such as Reservoirs (5.7) and Lakes (5.6). No really high breeding densities were found in Slovenia and were similar to those in other countries. Breeding densities are higher on smaller Ponds (< 8 ha), on sites with isolated islands and breeding colonies of gulls and terns (e.g. Lake Ptuj). Breeding density also decreases with elevation. Slovenian breeding population is estimated at 1,473–3,763 bp and wintering population averages 22,237 (10,376–32,010) individuals. Data suggest a decline in the wintering population most likely due to warmer winters. The majority of Mallards winter in NE Slovenia, where eight of eleven sites have a maximum of more than 1,000 Mallards. Most Mallards winter on the Drava river with Ptuj and Ormož lakes, where the highest numbers of Mallards were also recorded (Lake Ptuj: 8,330 ind., Lake Ormož: 5,400 ind.). The highest number of individuals during spring migration was recorded on Lake Cerknica (4,581) and during autumn migration on Medvedce reservoir (3,379). Apart from standing waters, the highest density of wintering Mallards is found in urban sections of slow-flowing rivers, probably due to higher safety and food availability.72,731 Mallards were hunted between 2001 and 2018, mainly in NE Slovenia (28% in the Pomursko hunting management district). The number of Mallards hunted is declining in all hunting areas and has declined by 64% since 2001 and even more since the 1990s. According to hunt data, hunting is by far the most important cause of the Mallard mortality in Slovenia (97.4%), followed by predation (1.1%). The Mallard mortality in Slovenia is largely unstudied and natural mortality is most likely underestimated, not only because it does not include mortality in the pre-fledging period, a period with the lowest survival, but also because the detectability of natural mortality is considerably lower. In contrast to the hunted numbers, there have been only nine recoveries of ringed individuals from abroad in the last 100 years, suggesting that hunters may not be reporting recoveries to the ringing centre. Apart from the 1972–1975 period, when 87% of Mallards were ringed, the intensity of ringing of Mallards in Slovenia is low, resulting in only seven Mallards recovered abroad. The longest distance of a Mallard ringed in Slovenia comes from Ukraine (1,290 km), while the longest distance between ringing and recovery sites is 2,075 km from an individual ringed in Finland. The only colour morphs documented in Slovenia are Mallards with paler feathers, attributed to one of the colour aberrations resulting from lower melanin productivity. Only few hybrids and mixed pairings with other wild duck species were observed.

The foraging of Great Cormorants Phalacrocorax carbo in Alpine rivers is a relatively recent phenomenon. Wintering populations in Slovenia increased in the 1980s. In the 1990s, the increase affected the upper sections of rivers where the habitats of Grayling Thymallus thymallus and trout Salmo and Oncorhynchus spp. are located. The upper section of the Soa River system is known as one of the biogeographic hotspots for (sub)alpine rivers, where several endemic or rare fish species are found. The aim of this study is to evaluate the diet of the Cormorants in this area and to compare it to some other threats to the fish fauna of the river. A total of 75 Cormorant stomachs were examined. Of these, 68 (90.7%) contained fish or recognisable fish remains. The birds' diet consisted of eight species of fish: Marble Trout, Rainbow Trout, Common Nase, Vairone, Common Chub, Italian Chub, Italian Barbel and Bullhead. The increase in numbers and the diet of Cormorants in the river basin of Soa is discussed in the context of the increase of other threats to this ecosystem, such as fish stocking, gravel extraction and tourism, especially angling and water sports. A more comprehensive environmental assessment of all these factors is needed, as their increase runs parallel with the arrival of the Cormorants in the upper section of the river. There is therefore reason to believe that Cormorants are only a small part of a larger problem in the conservation of the river ecosystem.

In 2016, the International Waterbird Census (IWC) was carried out in Slovenia on 16 and 17 Jan. Waterbirds were counted on all larger rivers, along the entire Slovenian Coastland and on most of the major standing waters in the country. During the census, in which 251 observers took part, 421 sections of the rivers and coastal sea with a total length of 1402.8 km and 223 other localities (180 standing waters and 43 streams) were surveyed. Altogether, 52,713 waterbirds of 55 species were counted. Thus, the number of waterbirds rose above the 20-year average of IWC in Slovenia (51.429), while the number of species recorded was one of the lowest so far. The highest numbers of waterbirds were counted in the Drava count area, i.e. 25,292 individuals (48.0% of all waterbirds in Slovenia). By far the most numerous species was Mallard Anas platyrhynchos (38.6% of all waterbirds), followed by Coot Fulica atra (16.8% of all waterbirds), Black-headed Gull Chroicocephalus ridibundus (5.6% of all waterbirds), Cormorant Phalacrocorax carbo (5.5% of all waterbirds) and Mute Swan Cygnus olor (4.9% of all waterbirds). The number of 1,000 counted individuals was also surpassed by Tufted Duck Aythya fuligula, Yellow-legged Gull Larus michahellis, Pygmy Cormorant P. pygmeus, Grey Heron Ardea cinerea and Teal An. crecca. Among the rarer recorded species, the Flamingo Phoenicopterus roseus, Jack Snipe Lymnocryptes minimus (both registered only for the third time during the IWC) and Marsh Harrier Circus aeruginosus (registered only for the second time during the IWC) deserve special mention. Numbers of the following species were the highest so far recorded during the IWC: Mute Swan, Greylag Goose Anser anser, Goosander Mergus merganser and Pygmy Cormorant. The lowest number during the IWC was not recorded for any of the species this year. Acrocephalus 37 (170/171): 209-219, 2016.

Waterbirds were counted on all larger rivers, along the entire Slovenian Coastland and on most of the major standing waters in the country. During the census, in which 276 observers took part, 409 sections of the rivers and coastal sea with a total length of 1385.8 km and 224 other localities (172 standing waters and 52 streams) were surveyed. Altogether, 46,425 waterbirds of 57 species were counted. This is one of the lowest numbers of waterbirds recorded during the 19 years of IWC in Slovenia. The highest numbers of waterbirds were counted in the Drava count area, i.e. 17,014 individuals (36.7% of all waterbirds in Slovenia). By far the most numerous species was Mallard Anas platyrhynchos (45.9% of all waterbirds), followed by Coot Fulica atra (8.4% of all waterbirds), Blackheaded Gull Chroicocephalus ridibundus (7.5% of all waterbirds), Cormorant Phalacrocorax carbo (5.7% of all waterbirds) and Mute Swan Cygnus olor (4.6% of all waterbirds). The number of 1000 counted individuals was also surpassed by Tufted Duck Aythya fuligula, Yellow-legged Gull Larus michahellis and Teal An. crecca. Among the rarer recorded species, the Cattle Egret Bubulcus ibis (registered only for the third time during the IWC) and Lesser Black-backed Gull Larus fuscus (registered only for the fourth time during the IWC) deserve special mention. Also, Ruddy Shelduck Tadorna ferruginea was recorded for the fourth time during the IWC, but the individual observed was classified to category E (introduced species without self-sustaining populations, escapees from captivity). Numbers of the following species were the highest so far recorded during the IWC: Greylag Goose Anser anser, Muscovy Duck Cairina moschata, Shoveler An. clypeata, Goosander Mergus merganser and Common Sandpiper Actitis hypoleucos. The number of Redbreasted Mergansers M. serrator was the lowest so far recorded during the IWC.

The present article is an upgrade and update of national checklists published by the Slovenian Rarities Committee in the past. A species is considered rare if fewer than 10 records are known after 1st January 1950. The number of records for these species is given in the list. Additionally, species designated as rare in the last edition of the list and extinct breeders were also considered. All records after 1st January 2001, included in the list, were confirmed by the current Slovenian Rarities Committee. Data collection for the period between 1st January 1800 and 31st December 1949 was centred on evaluating written sources, which were the basis for inclusion of a species into previous editions of the list. The data classification and taxonomy follow the recommendations of the British Ornithologists' Union. The list includes species observed at least once between 1st January 1800 and 31st December 2011. The list of birds recorded in Slovenia contains 380 species, of which 365 are in Category A, seven in Category B and eight in Category C. Category D contains six and Category E 29 species. These species are not part of the list. In comparison with the last version of the list published in 2001, 10 species recorded in Slovenia for the first time during this period were added. Two species were added because of taxonomic changes and five due to changes in species categories. Seven species were removed from the list owing to inaccurate information in historic written sources or misidentification.
