Tenerife Blue Chaffinch
Fringilla teydea
Endemic to the island of Tenerife in the Canary Islands. Medium-sized finch with a strong and heavy bill and broken white eyering. Male is a striking dark blue-gray while female is brown-gray. Largely restricted to montane pine forests. Song is a repetitive, accelerating series; call is a “pi”chewee.”
识别特征
Tenerife blue chaffinches resemble common chaffinches, but they are noticeably larger, and have a thicker bill. They are characteristically more uniform in their plumage, and they lack a dark cap. Females are a dull grey-brown, but can be distinguished from chaffinches by their weaker wing bars. Breeding males are unmistakable, with the namesake largely blue plumage and a grey bill.
分类信息
Until 2015, the species Fringilla teydea was classified into two subspecies: Fringilla teydea polatzeki from Gran Canaria and Fringilla teydea teydea from Tenerife. However, a study published in March 2016 showed that a classification as different species, Fringilla polatzeki and Fringilla teydea, is justified.

行为
The Tenerife blue chaffinch's song is shorter and weaker than that of the common chaffinch, and the flight call is croakier. It primarily eats Canary Island pine seeds. Like the common chaffinch, but unlike most other finches, its young are fed extensively on insects. Breeding from the end of April to late July or early August, it builds a nest from pine needles and broom branches, and lays two eggs. This bird is not migratory. Individuals may form small flocks outside the breeding season, sometimes associating with common chaffinches and other finches.

Solitary Tinamou
Tinamus solitarius
Large, dumpy, almost tailless terrestrial inhabitant of the Atlantic Forest, where it walks quietly through forests with an open understory. This tinamou has a gray-brown barred back and vent, pale gray on the belly with a prominent pale stripe on the side of the neck. Very secretive, best identified by song, a series of “frru” whistles with long silences between them.
Northern Beardless-Tyrannulet
Camptostoma imberbe
Tiny flycatcher found in Mexico and Central America. In the U.S. restricted to riparian woodland with dense understory and mesquite in the Southwest. Plain gray overall with inconspicuous pale wingbars and pale yellowish belly. Peaked bushy crown. Similar to Empidonax flycatchers but note bushy crest, blunter bill, and less obvious wingbars. Generally quite active. Often detected by song: a series of descending plaintive whistles "dee dee dee dee."
Flame-breasted Fruit-Dove
Ramphiculus marchei
A fairly large dove of foothill and low-elevation montane forest canopy. Pale gray from the belly to the sides of the chest and neck, with a sooty back and cheek, an orange chest patch with dark red below, and a pink crown and mark across the flight feathers. Similar to the Yellow-breasted Fruit-Dove, but Flame-breasted has an orange rather than yellow chest and a dark pink crown. Song is a deep, rising-then-falling “oo-woo.” Takes flight with loud wing claps.
