分类信息

The Carrizal seedeater was described based on three specimens collected in 2001. The researchers who determined that it was a new species, Miguel Lentino and Robin L. Restall, named it Carrizal blue seedeater, but the "blue" was dropped by taxonomic organizations to avoid conflict with what was then the blue seedeater (Amaurospiza concolor).

分布与栖息地

The specimens of Carrizal seedeater were collected on Isla Carrizal in the Caroni River of northern Venezuela. Construction of the Tocoma Dam, which began in 2006, flooded the island. The species has since been found elsewhere in the Caroni River watershed. It is known only from stands of spiny Guadua and Ripidocladus species of bamboo in deciduous forest.

Antipodes Parakeet

Antipodes Parakeet

Cyanoramphus unicolor

Entirely green parakeet endemic to the subantarctic Antipodes Islands. The largest of New Zealand’s native parakeets. Males are larger than females. Common throughout their habitat and range, walking and climbing through vegetation when foraging. Will scavenge bird carcasses. An inquisitive bird, often approaching human visitors. Call is a distinctive deep “kok-kok-kok-kok” chatter. Shares its range with Reischek’s parakeet, but distinguishable by much larger size and lack of a red crown.

Fire-capped Tit

Fire-capped Tit

Cephalopyrus flammiceps

More of a soft blush than a burning flame, the red patch on the male’s face is nonetheless unique. The female lacks the red patch, but is still distinctive in her size, small sharp bill, and pale wingbars. Both sexes are yellow above and pale gray below, with the male being more predominantly yellow than the female. Found in montane broadleaf forest at middle to high elevations, sometimes mixed in with other species; some populations descend to lower foothills and lowlands in the winter. Song is an undulating series of twitters, chips, and trills; also twitters and trills when flocking.

Philby's Partridge

Philby's Partridge

Alectoris philbyi

Handsome partridge of the southwest Arabian mountains. Mostly pale gray and tan, with chestnut-and-white slashes along the sides, and a black face mask. In flight, shows dark wingtips and chestnut sides to the tail. Found in dry, rocky habitat at middle and high elevations, with a preference for bush areas. The common vocalization, given mainly early and late in the day, is an emphatic series of “chuk-chek-chuk” calls. Also gives clucking calls, especially when flushed. Similar to Arabian Partridge, but distinguished by the black face mask, and when in flight, by the chestnut in the tail.
