Empidonax
The genus ''Empidonax'' is a group of small insect, insect-eating passerine birds in the tyrant flycatcher family, the Tyrannidae. The genus name ''Empidonax'' is from Ancient Greek ''empis'', "gnat", and ''anax'', "master". Most of these birds are very similar in Feather, plumage: olive on the upper parts with light underparts, eye rings and wing bars. In the nesting season they may be distinguished by range, habitat (ecology), habitat and call; in other situations, particularly on bird migration, migration and in winter, it may not be possible to be sure of specific identification. ''Empidonax'' flycatchers often flick their wings and tails rapidly. Euler's flycatcher, ''Lathrotriccus euleri'' and gray-breasted flycatcher, ''Lathrotriccus griseipectus'' were formerly placed in ''Empidonax'', but differ anatomically and biochemically and are now placed in the genus ''Lathrotriccus''.

Least Flycatcher
The least flycatcher (''Empidonax minimus'') (also called chebec, or chebecker, after the sound it makes) is a small insect-eating bird. It is the smallest ''Empidonax'' flycatcher in eastern North America. Taxonomy The closest relative to the least flycatcher was long thought to be the Hammond's flycatcher based on similarities in their songs and appearances. However, mitochondrial DNA analysis has revealed that the least flycatcher diverges significantly from its congeners and does not possess any sister taxa. Description The least flycatcher is hard to distinguish from the other birds of its genus. The bird is one of the smallest of the genus ''Empidonax'', measuring 12 to 14 cm in height with a wingspan of 19 to 22 cm and weighing approximately 10.3 g. Its plumage is dull olive-gray on its back and whitish on its belly, notably brighter than the other ''Empidonax'' birds. The least flycatcher's wings are lined with two white bars, and white rings contour its ey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyrant Flycatcher
The tyrant flycatchers (Tyrannidae) are a family of passerine birds which occur throughout North and South America. They are considered the largest family of birds known to exist in the world, with more than 400 species. They are the most diverse avian family in every country in the Americas, except for the United States and Canada. The members vary greatly in shape, patterns, size and colors. Some tyrant flycatchers may superficially resemble the Old World flycatchers, which they are named after but are not closely related to. They are members of suborder Tyranni (suboscines), which do not have the sophisticated vocal capabilities of most other songbirds.del Hoyo, J. Elliott, A. & Christie, D. (editors).

Alder Flycatcher
The alder flycatcher (''Empidonax alnorum'') is a small insect-eating bird of the tyrant flycatcher family. The genus name ''Empidonax'' is from Ancient Greek ''empis'', "gnat", and ''anax'', "master". The specific ''alnorum'' is Latin and means "of the alders". Description ''E. alnorum'' is one of the larger ''Empidonax'' species, attaining a length of , and a mass of . The wingspan ranges from . Upperparts of ''E. alnorum'' are dull greenish-olive. The crown is a slightly darker olive-green than the back. The throat is white, with a darker breast band. Thin white rings surround the eyes. The bill is wide and moderate in length, with pinkish or yellow-orange lower mandible and black upper mandible. Wings are generally black, with white wing bars and white edges of the innermost secondaries (tertials). Juveniles have brownish upperparts, yellow underparts, and yellowish brown or buff wingbars.All about birds nternet(2015). Ithaca (NY): Cornell University; pdated 2015; cited 20 ...

Willow Flycatcher
The willow flycatcher (''Empidonax traillii'') is a small insect-eating, neotropical migrant bird of the tyrant flycatcher family. There are four subspecies of the willow flycatcher currently recognized, all of which breed in North America (including three subspecies that breed in California). ''Empidonax'' flycatchers are almost impossible to tell apart in the field so biologists use their songs to distinguish between them. The binomial commemorates the Scottish zoologist Thomas Stewart Traill. Description and ecology Adults have brown-olive upperparts, darker on the wings and tail, with whitish underparts; they have an indistinct white eye ring, white wing bars and a small bill. The breast is washed with olive-gray. The upper part of the bill is gray; the lower part is orangish. At one time, this bird and the alder flycatcher (''Empidonax alnorum'') were considered to be a single species, Traill's flycatcher. The willow and alder flycatchers were considered the same species u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Grey Flycatcher
The American gray flycatcher, or American grey flycatcher, or just gray flycatcher (''Empidonax wrightii'') as it is known in North America, is a small, insectivorous passerine in the tyrant flycatcher family. It is common in the arid regions of western North America, especially the Great Basin. From sagebrush steppes to pinyon-juniper woodlands and ponderosa pine forests, this flycatcher forages for insects from shrubs or low tree branches. The American gray flycatcher is one of the many species in the genus ''Empidonax''. These species are very similar in appearance and behavior, and they are notoriously difficult to differentiate. The best characteristics for distinguishing these species are voice, breeding habitat, and range. The American gray flycatcher, however, can be identified by a unique behavior, its downward tail wag. Other ''Empidonax'' species typically exhibit a rapid upward tail flick. Description American gray flycatchers are small birds, but larger than most ...

Yellow-bellied Flycatcher
The yellow-bellied flycatcher (''Empidonax flaviventris'') is a small insect-eating bird of the tyrant flycatcher family. Description Adults have greenish upperparts and yellowish underparts (especially on the throat), with a dusky wash on the chest. They have a white or yellow eye ring that lacks the teardrop projection of Pacific-slope ('' E. difficilis'') or cordilleran ('' E. occidentalis'') flycatchers, white or yellowish wing bars that contrast strongly against the black wings, a broad, flat bill, and a relatively short tail when compared to other members of the genus. The upper mandible of the bill is dark, while the lower mandible is orange-pink. DNA testing in 2014 confirmed a field mark, involving the extent of buffy edging on the secondaries, to reliably distinguish this species from the two so-called " Western Flycatchers." Measurements: * Length: * Weight: * Wingspan: Yellow-bellied flycatchers wait on a perch low or in the middle of a tree and fly out to catc ...

Hammond's Flycatcher
Hammond's flycatcher (''Empidonax hammondii'') is a flycatcher in the family Tyrannidae. This small insectivorous bird inhabits the coniferous and mixed forests of western North America. The name of this bird commemorates William Alexander Hammond who was the surgeon general of the US Army. Hammond collected bird specimens for Spencer Fullerton Baird. Description Adults are 12–14 cm long (4.7-5.5 in), span about 22 cm (8.7 in) across the wing and weigh 8-12 g (0.3-04 oz). They have grayish-olive upperparts, darker on the wings and tail, with whitish underparts; they have a conspicuous white eye ring, white wing bars, a small bill and a short tail. The breast is washed with grey and the sides of the belly with yellow. Female usually have a shorter, wider bill compare with male's. Immature are similar to adults, but have broader wing bars and are more buff. Many species of ''Empidonax'' flycatchers look closely alike. Hammond's flycatchers are mainly c ...

American Dusky Flycatcher (Empidonax Oberholseri) (8079381798)
The American dusky flycatcher (''Empidonax oberholseri''), or simply dusky flycatcher, is a small insectivorous passerine of the tyrant flycatcher family. The dusky flycatcher is one of many species in the genus ''Empidonax''. These species are very similar in appearance and behavior, and they are notoriously difficult to differentiate. The best characteristics for distinguishing these species are voice, breeding habitat, and range. Description Adults have olive-gray upperparts, darker on the wings and tail, with whitish underparts; they have a noticeable medium-width white eye ring, white wing bars and a medium length tail. The breast is washed with olive-gray. The bill is mainly dark. It is a bit smaller than the American grey flycatcher and a bit larger than the Hammond's flycatcher. Vocalizations The male sings a three-part song. A common call is a dry ''whit'', similar to that of other ''Empidonax'' flycatchers. A less common call that is possibly only given by male is a sa ...
