... While the return of some translocated birds to Raso across 16 km of sea was not unexpected, Raso larks had never been seen on Santa Luzia prior to this project. Therefore the unassisted movements of three colourringed birds from Raso to Santa Luzia was not anticipated, even allowing for the single 2009 sighting of a Raso lark on Sao Nicolau some 20 km to the east of Raso (Hazevoet, 2012). Although greater observer effort on Santa Luzia of course increases the chance of seeing visiting larks, it seems probable that larks have been visiting Santa Luzia for years, but only sighted recently. ...
Confined to a single island where its small population fluctuates in response to rainfall, the Raso lark is likely to remain Critically Endangered unless a second population becomes established. This paper reports translocations of larks, 37 in 2018 and 33 in 2019, to the nearby island of Santa Luzia where the species existed until about 500 years ago. Both islands lie within the Reserva Natural Integral de Santa Luzia. While the hard release protocol proceeded without mishap, problems with radio-tagging the released birds were encountered. However early indications are encouraging; the released birds have bred, and their annual survival is not substantially worse than that of larks on the source island, Raso. Unexpectedly, the study documented several natural, unassisted movements of larks from Raso to Santa Luzia (and, less unexpectedly, of translocated birds returning to Raso). The ultimate outcome of the project remains uncertain since eradication of Santa Luzia’s introduced cats, possible predators of the larks, was interrupted when the island was evacuated because of the Covid-19 pandemic.
... The major habitats vary from eroded rocky plains and sand dunes to dry grasslands. Santa Luzia's fauna has been poorly studied and only 57 terrestrial invertebrates, three terrestrial reptiles, eight breeding birds and one mammal species have been reported so far (Arechavaleta et al., 2005;Hazevoet, 2012;Masseti, 2010). ...
Studies on feral cat diet offer important ecological information and are the first step towards determining their impact upon endangered species. However, in comparing seasonal changes in diet with seasonal prey availability, the scarce amount of research into oceanic islands worldwide must be considered when deciding if a specific population is actually affected by cat predation. Cat diet was analysed on Santa Luzia (Cabo Verde Islands) since this invasive predator is considered one of the main threats to native endangered species that require conservation measures. These previous studies were carried out in different seasons, providing contrasting results, skinks being more preyed upon in the rainy season and mice in the driest periods. To check these different results, we focussed on how cat diet varied seasonally in response to changes in prey abundance. Saurians were the most important prey group, followed by mice, invertebrates and birds. No seasonal differences were, however, observed in the different prey groups consumed, saurians being the main prey in both seasons. All cases reflected their respective abundances. Results corroborate the generalist and opportunistic trophic ecology of feral cats, providing important information to assess their impact on prey populations and design future eradication programmes.
... comm.). In the Cape Verde Islands, it is a frequent passage visitor, mostly recorded from September to December (Hazevoet 1995(Hazevoet , 2012. It has been recorded off Guinea-Bissau recently but no details are available (M. Lecoq pers. ...
We report at least 103 Great Shearwaters Ardenna gravis found between 22 and 27 June 2011, washed up along 7 km of beach between Tanji Bird Reserve and Tranquil Beach, Coastal Western Region, The Gambia. This discovery represents the first Gambian record of this species and at a time of the year that it was not expected in Senegambian waters. A photographic record was made in situ each day of the numerous shearwater remains, most of which had been scavenged by ghost crabs Ocypode spp. and some by Hooded
Vultures Necrosyrtes monachus. Measurements of 18 cleaned skulls are presented. We summarise published sightings of Great Shearwater for Senegal, Mauritania and the Cape Verde islands and provide new information for Senegal. Movements of satellite-tracked Great Shearwaters from their breeding grounds in the southern hemisphere to the North Atlantic are discussed as well as their foraging strategies during this migration. Starvation
is proposed as the probable cause of the wreck. Pelagic studies during the rainy season and discussions with artisanal fishermen operating in Senegambian waters are needed to reveal the status of many seabirds in these under-explored waters.
... This is the first record for the Cape Verde Islands (cf. Hazevoet 1995, 1997, 1998, 1999, 2003, 2012, 2014, Hazevoet et al. 1996. ...

Summary.—Report on rare birds in Spain, 2012-2013. This report publishes 636 new records on the presence of 151 taxa of rare birds in the whole of Spain, with an acceptance rate of 86.64%. Details on 8 new taxa for Spain are included for the first time in any rarities report: macaronesian shearwater Puffinus baroli boydi, double-crested cormorant Phalacrocorax auritus, bateleur Terathopius ecaudatus, common buzzard Buteo buteo vulpinus, red-necked stint Calidris ruficollis, Wilson’s snipe Gallinago delicata, short-billed dowitcher Limnodromus griseus and Asian desert warbler Sylvia nana. moreover it has been accepted the first records for two taxa for the Spanish peninsula: Fea’s petrel Pterodroma feae and south polar skua Stercorarius maccormicki, and the first records for a total of 6 new taxa for Spain or the Peninsula which are considered to be maintained in D category: tropical mockingbird (Mimus gilvus; first record for Spain), common bulbul Pycnonotus barbatus, African blue tit Cyanistes teneriffae, brown-necked raven Corvusruficollis, pied crow (Corvus albus; first record for Spain) and Italian sparrow (Passer italiae; first record for Spain). Also, the second records for Spain for black-bellied storm petrel Fregetta tropica and Hume’s warbler Phylloscopus humei. We also include the first records for Canary Islands of water rail Rallus aquaticus, semipalmated plover (Charadrius semipalmatus; 4th record for Spain), little auk Alle alle, great reed warbler Acrocephalus arundinaceus and little bunting Emberiza pusilla. Finally is also commented the big influxes of yellow-browed warblers Phylloscopus inornatus and new records of sandhill crane Grus canadensis.
Report on rare birds in Spain 2008. This is the 25th annual report of the Spanish rarities committee (Comité de Rarezas de SEO/BirdLife). Up to 294 new accepted records from 89 rare bird taxa are given (acceptance rate of 84%). Additions to the Spanish List were the first observation assigned to the species pair Zino’s/Fea’s petrel Pterodroma madeira/feae, the first steppe eagle Aquila nipalensis, Arctic warbler Phylloscopus borealis and Kumlieni’s gull Larus glaucoides of the nearctic race kumlieni. It has also been a first record for Spain the observation of an Egyptian plover Pluvianus aegyptius of a dubious origin, on the southeastern coast of the Iberian Peninsula. In addition, the report provides an update on the extended presence of tricolored heron Egretta tricolor on Tenerife Island, a new species in Spain already accepted the previous year. This report includes the second record of magnificent frigatebird Fregata magnificens and the third records of bar-tailed lark Ammomanes cinctura, moussier’s redstart Phoenicurus moussieri and a feasible hybrid of green-winged teal Anas carolinensis with Eurasian teal A. crecca. The observations of semipalmated sandpiper Calidris pusilla, Baird’s sandpiper Calidris bairdii and citrine wagtail Motacilla citreola were also third records for the Canary Islands. Successful breeding was documented for both red-billed tropicbird Phaethon aethereus and little swift Apus affinis, in the Canary Islands for the second time and in southern Spain for the eighth consecutive year, respectively. The report contains also unprecedented numbers of yellow-browed warbler
Phylloscopus inornatus and pectoral sandpiper Calidris melanotos.

The diet of feral cats Felis catus on Santa Luzia, Cape Verde Islands, was studied. A total of 147 prey items were identified during the analysis of 26 scat groups collected during the summer of 2010. House mouse Mus musculus was the most important prey, both in percentage of biomass and number of preys consumed (89.7% and n= 117, respectively). Reptiles were the second most important prey, represented by one skink species (Chioninia stangeri) and an unidentified gecko species. The remainder of the identified prey consisted of one bird species (Passer iagoensis) and one undetermined Tettigoniidae species (Insecta). No endangered species were identified in scats of this introduced predator, but future surveys must be carried out to further avoid threats to the island's biodiversity. RESUMO Foi estudada a dieta de gatos assilvestrados Felis catus na ilha de Santa Luzia, Cabo Verde. Foram identificadas 147 presas de um total de 26 dejectos recolhidos no Verão de 2010. A presa mais importante, tanto em percentagem de biomassa como em número de presas consumidas, foi o rato doméstico Mus musculus (89.7% e n= 117, respectivamente). Os répteis foram a segunda presa mais importante, maioritariamente lagartos (Chioninia stangeri), bem como de uma espécie não identificada de osga. Outras presas identificadas foram uma ave (Passer iagoensis) e uma espécie não identificada de Tettigoniidae (Insecta). Não foi detectada nenhuma espécie com estatuto de ameaça na dieta deste predador introduzido, porém outras monitorizações futuras deverão ser implementadas para evitar ameaças à biodiversidade desta ilha.
