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).

Yellowish Flycatcher
The yellowish flycatcher (''Empidonax flavescens'') is a small passerine bird in the tyrant flycatcher family. It breeds in highlands from southeastern Mexico south to western Panama. Description The yellowish flycatcher is long and weighs . Its upper parts are olive-green and the underparts are yellow with an ochre tint to the breast. The wings are blackish with two buff wing bars. It has a white eye ring broadening into a small triangle behind the eye. Sexes are similar, but young birds are browner above and paler yellow below. The call is a thin ' and the dawn song is a rapid repeated '. This species needs to be distinguished from migratory ''Empidonax'' species, since several species, including willow, alder and Acadian flycatchers pass through in the autumn. It has a more prominent eye ring than any migrant species, and despite that species’ name, is yellower below than yellow-bellied flycatcher. Distribution and habitat This species is found in cool mountain forest, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basal (phylogenetics)
In phylogenetics, basal is the direction of the ''base'' (or root) of a phylogenetic tree#Rooted tree, rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Note that extant taxa that lie on branches connecting directly to the root are not more closely related to the root than any other extant taxa. While there must always be two or more equally "basal" clades sprouting from the root of every cladogram, those clades may differ widely in taxonomic rank, Phylogenetic diversity, species diversity, or both. If ''C'' is a basal clade within ''D'' that has the lowest rank of all basal clades within ''D'', ''C'' may be described as ''the'' basal taxon of that rank within ''D''. The concept of a 'key innovation' implies some degree of correlation between evolutionary innovation and cladogenesis, diversification. However, such a correlation does not make a given ca ...

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''.

Myiarchus
''Myiarchus'' is a genus of tyrant flycatchers. Most species are fairly similar looking and are easier to separate by voice than plumage. ''Myiarchus'' flycatchers are fairly large tyrant-flycatchers at 16–23 cm (6.3–9 in) long. They are all partially crested with a brown to gray back and head, a rufous to blackish tail and yellow to pale underparts (only exception is the rufous flycatcher with rufous underparts). They typically forage by perching on an open branch and looking outward and downward for prey, which primarily consists of insects. Once it spots a potential meal, the flycatcher rapidly and directly flies at the insect, which is normally on the exposed upper surface of a leaf or twig. It hovers briefly before the insect before grabbing it in its beak and flying away to typically a new perch. The genus contains 22 species: * Rufous flycatcher, ''Myiarchus semirufus'' * Yucatan flycatcher, ''Myiarchus yucatanensis'' * Sad flycatcher, ''Myiarchus barbiros ...

Elaenia
''Elaenia'' is a genus of passerine birds in the tyrant flycatcher family which occur in Mexico, the Caribbean, and Central and South America. Except by voice, specific identification is often difficult since many species are very similar. They are also known by the common name elaenia, which they share with the similar tyrant flycatchers of the genus '' Myiopagis''. ''Elaenia'' flycatchers are typically brownish, greyish or olive above, and off-white and/or pale yellow on the belly, with a white or pale yellowish eye-ring of variable strength and two or three wing bars. Some species show a crest; often with a semi-concealed white patch/streak. Taxonomy The genus ''Elaenia'' was introduced by the Swedish zoologist Carl Jakob Sundevall in 1836. The type species was subsequently designated as the yellow-bellied elaenia. The name of the genus is from the Ancient Greek Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from ...

Crest (feathers)
The crest is a prominent feature exhibited by several bird and other dinosaur species on their heads. It is distinct from features such as casques and cockscombs - sometimes erroneously referred to as "crests", which are bony and fleshy structures respectively. The crest is made up of semiplume feathers: a long rachis with barbs on either side. These are plumulaceous feathers, meaning that they are soft and bendable. In birds, these semiplumes are common along the head, neck, and upper back, and may be used for buoyancy and sensing vibrations. Crests on birds are generally used for display purposes. Cockatoos and their smaller cousins, cockatiels, are part of the parrot family Cacatuidae found in Australia, the Bismarck Archipelago and the Philippines, and are probably the most recognizable birds to feature crests. Cockatoos and cockatiels possess crests which may be raised or lowered at will. Their crests are used to communicate with fellow members of their species, or as a fo ...

Ornate Flycatcher
The ornate flycatcher (''Myiotriccus ornatus'') is a species of bird in the family Tyrannidae. It is the only member of the genus ''Myiotriccus''. It is found in Colombia, Ecuador, and Peru. The ornate flycatcher is a fairly small flycatcher at an average length of 12 cm (4.7 in) and weighing about 13.5 grams (0.5 oz). It is very distinctive in the field due to its bright yellow belly, white post-ocular spots, dusky head and conspicuous large yellow rump against dusky wings. In Ecuador, the mantle and tail are rusty colored in East Slope birds and earth brown in West Slope birds. The ornate flycatcher's natural habitat is subtropical or tropical moist montane forests.

Rufous
Rufous () is a color that may be described as reddish-brown or brownish-red, as of rust or oxidised iron. The first recorded use of ''rufous'' as a color name in English was in 1782. However, the color is also recorded earlier in 1527 as a diagnostic urine color. The word "rufous" is derived from the Latin ''rufus'', meaning "red", and is used as an adjective in the names of many animals—especially birds—to describe the color of their skin, fur, or plumage.
