Greenish Warbler
Phylloscopus trochiloides
Green on the back and pale below; has a strong white eyebrow which is broad behind the eye and goes all the way to the forehead. Usually has one broad pale wingbar. Can be very unobtrusive and difficult to spot. Breeds in lowland and montane deciduous and mixed forest. Song is a high-pitched long series "tsit-psityee psityu-psi-ti-ti-ti-ti-si," but often detected by its call, a two-parted "t-sli" with flat or downward inflection. Similar to Green Warbler which co-occurs on wintering ground, best separated by call and Green's brighter green back and yellower underside.
识别特征
The greenish warbler (Phylloscopus trochiloides) is a widespread leaf warbler with a breeding range in northeastern Europe, and temperate to subtropical continental Asia. This warbler is strongly migratory and winters in India. It is not uncommon as a spring or early autumn vagrant in Western Europe and is annually seen in Great Britain. In Central Europe large numbers of vagrant birds are encountered in some years; some of these may stay to breed, as a handful of pairs does each year in Germany. Like all leaf warblers, it was formerly placed in the "Old World warbler" assemblage, but now belongs to the new leaf-warbler family Phylloscopidae. The genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific trochiloides is from Ancient Greek trokhalos, "bowed", and -oides "resembling", from the similarity to the willow warbler, P. trochilus. The English name of this species provides a perfect argument in favour of the capitalisation of species names (i.e. treating them as proper nouns), a convention which is generally applied in scientific literature. The decapitalised "greenish warbler" is equally descriptive of many bird species across multiple families, whereas a capitalised "Greenish Warbler" shows unambiguously that Phylloscopus trochiloides is under discussion.

Northern Pygmy-Owl
Glaucidium gnoma
Small diurnal owl of forests of the mountainous western US and interior Mexico. Scarce and often difficult to find, but sometimes perches conspicuously. Brown and white overall with yellow eyes and bill. Sometimes cocks tail up or sideways. Look for large black eye-spots on nape when facing away. Feeds mainly on small birds and mammals. Different populations give slightly different versions of a series of single or paired toots. Northern Saw-whet Owl is fairly similar in plumage, but never perches out in the open in daylight.
Buffy Hummingbird
Leucippus fallax
Medium-sized brown-and-green hummingbird. Upperparts pale green, underparts warm buff; bill medium-sized; has dull white spot behind eyes and boldly white tipped, rounded tail. Locally fairly common; territorial. Restricted to desert scrub, dry forest edges, and mangroves in northern Venezuela and extreme northeastern Colombia. Ruby Topaz female similar but with rufous tail and shorter bill.
Muisca Antpitta
Grallaria rufula
Plump bird with long legs and a short tail that ranges in the eastern Andes of Colombia, barely reaching over the border into Venezuela. Plumage is chestnut brown with an orange tinge to the breast and slightly paler belly; sometimes shows a faint mustache streak. Skulks in the understory of high elevation elfin forest and usually stays on the ground, but sometimes comes up to a low perch to sing. Common vocalization is a sweet, rising whistle followed by a lower pitched gargle, and also gives a series of flat whistles. It used to be called Rufous Antpitta.
