This is a first report of the overwintering thermoregulation incidence, and behavior of an individual Bogertophis subocularis.

A Barred Owl (Strix varia) landing on a stump with a siren in its talons on 5 Feb 2012 at 2227 h. The species is probably the Lesser Siren (Siren intermedia) as several have been captured in the marginal swampy areas of the stream. Wildlife camera set up by Whit Gibbons.

An American Bittern, Botaurus lentiginosus, preying on the Greater Siren, Siren lacertina, Brevard Co., Florida, USA.

A) Male Leptodactylus savagei with body lowered to the ground prepared to move forward. B) Male lunged forward by force from hind legs. C) The individual Leptodactylus savagei stretched with right foreleg in front as the individual crawled forward. D) Male halts crawl and the crouched position is reassumed.

Front (upper) and dorsolateral (lower) views of an adult Limnonectes palavanensis with ocular anomaly found at the Ulu Kimanis Substation, Crocker Range National Park, Sabah, Malaysia.

An array of Lithobates sylvaticus egg masses in trees above the pond. Heights above water level ranged from 0 to ca. 1.75 m. The hypothesized laying-freezing-thawing event appears to only have affected those eggs laid early during the breeding season.
