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.

分布与栖息地
This bird is found only in the highlands of Tenerife.<p>The species' primary habitat is mountain Canary Island pine (Pinus canariensis) forest. It is most common in coniferous forest areas with dense undergrowth, but it is also found in laurel and pine woodland, tree-heath, and scrub.It prefers habitat at around 1,100–2,000 m (3,600–6,600 ft), but it will descend in bad weather.

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.

Yellow-bellied Elaenia
Elaenia flavogaster
Rather bulky small flycatcher, widespread in tropical lowlands. Fairly common in overgrown brushy clearings, savannas, and other semi-open areas with scattered bushes. Looks like many other small flycatchers, and where multiple species of elaenias occur it is often not possible to identify birds to species. On Yellow-bellied, note its spiky, white-based crest (rarely held flattened), burry drawled call, whitish wingbars, and pale yellow belly; does not flick its wings or tail.
Large Hawk-Cuckoo
Hierococcyx sparverioides
This species’ maddening song can be likened to the phrase “brain-FEVER,” which adequately describes what this bird gives birders trying to see one as it sings high up in the forest canopy. If seen well, note hawk-like appearance, with a long barred tail, brown upperparts, and patterned white underparts. Orangish flush on chest apparent in adults. Favors hill and montane forests when breeding; often found at lower altitudes and in forest edge and scrubby areas when migrating and on wintering grounds.
Lewin's Honeyeater
Meliphaga lewinii
A medium-sized olive-gray honeyeater with a pale yellow cheek patch and a relatively stout bill. Cheek patch is often a crescent compared to the circular patch on Graceful Honeyeater and the oval path on Yellow-spotted Honeyeater. Adults have a bluish eye, while the similar Graceful Honeyeater has a blue-gray eye and Yellow-spotted Honeyeater has a brown eye. Listen for the rapid staccato machine-gun call of Lewin’s compared to the loud repeated whistles of the Yellow-spotted Honeyeater and the more simple, single note call of Graceful Honeyeater. Of the three easily confusable species, this is the only one found away from the tropics; it occurs in wetter forests and gardens all along the eastern coast of Australia.
