The American bushtit or simply bushtit is a social songbird belonging to the genus Psaltriparus. It is one of the smallest passerines in North America and it is the only species in the family Aegithalidae that is found in United States; the other seven species are found in Eurasia.
Cardinalidae is a family of New World-endemic passerine birds that consists of cardinals, grosbeaks, and buntings. It also includes several other genera such as the tanager-like Piranga and the warbler-like Granatellus. Membership of this family is not easily defined by a single or even a set of physical characteristics, but instead by molecular work. Among songbirds, they range from average-sized to relatively large, and have stout features, some species with large, heavy bills.
The orchard oriole is the smallest species of icterid. The subspecies of the Caribbean coast of Mexico, I. s. fuertesi, is sometimes considered a separate species, the ochre oriole or Fuertes's oriole.
The bluish-grey saltator or Amazonian grey saltator is a passerine bird in the tanager family Thraupidae that is widespread in semi-open habitats in tropical and subtropical South America.
The blood pheasant or blood partridge is the only species in genus Ithaginis of the pheasant family. It is a relatively small, short-tailed pheasant that is widespread and is fairly common in eastern Himalayas, ranging across India, Nepal, Bhutan, China, and northern Myanmar. Since the trend of the population appears to be slowly decreasing, the species has been evaluated as of least concern on the IUCN Red List in 2009.
Grosbeak is a form taxon containing various species of seed-eating passerine birds with large beaks. Although they all belong to the superfamily Passeroidea, these birds are not part of a natural group but rather a polyphyletic assemblage of distantly related songbirds. Some are cardueline finches in the family Fringillidae, while others are cardinals in the family Cardinalidae; one is a member of the weaver family Ploceidae. The word "grosbeak", first applied in the late 1670s, is a partial translation of the French grosbec, where gros means "large" and bec means "beak".
The crimson-collared tanager is a rather small Middle American songbird. It was first described by the French naturalist René-Primevère Lesson in 1831, its specific epithet from the Latin adjective sanguinolentus, "bloodied", referring to its red plumage.
The Mexican violetear is a medium-sized, metallic green hummingbird species commonly found in forested areas from Mexico to Nicaragua. This species, together with the lesser violetear were previously considered conspecific, and together called the green violetear.
The black-headed grosbeak is a medium-sized, seed-eating bird in the family Cardinalidae. It is sometimes considered conspecific with the rose-breasted grosbeak with which it hybridizes on the American Great Plains.
The yellow grosbeak, also known as the Mexican yellow grosbeak, is a medium-sized seed-eating bird in the same family as the northern cardinal, "tropical" or "New World" buntings, and "cardinal-grosbeaks" or New World grosbeaks.
The black-chinned sparrow is a small bird in the genus Spizella, in the New World sparrow family Passerellidae. It is found in the southwestern United States and throughout much of Mexico north of the Isthmus of Tehuantepec; most populations in the US migrate south after breeding while those in Mexico are resident. It is a slim, long-tailed bird, primarily gray with a reddish-brown back streaked with black, brown wings and tail, a pink beak, and brownish legs and feet. In the breeding season, the male shows black on his throat, chin, and the front of his face. Females, youngsters and nonbreeding males show little or no black in these areas. An unobtrusive bird, it spends much of its time foraging slowly along the ground, either alone or in small groups, sometimes mixing with other Spizella species. It is an omnivore, feeding primarily on seeds during the winter and insects during the summer. It builds a cup-shaped nest of grasses, rootlets, or plant fibers, into which the female lays 2–5 pale blue eggs. The female does most or all of the egg incubation, but both parents feed the hatched nestlings.
The hooded grosbeak is a passerine bird in the finch family found in the highlands of Central America, principally in Mexico and Guatemala.
The Montezuma quail is a stubby, secretive New World quail of Mexico and some nearby parts of the United States. It is also known as Mearns's quail, the harlequin quail, and the fool quail.
The red-and-black grosbeak is a species of bird in the family Cardinalidae, the cardinals or cardinal grosbeaks. It is found in Brazil, French Guiana, Guyana, Suriname, and Venezuela.
The Yucatan nightjar is a species of nightjar in the family Caprimulgidae. It is found in Belize, Guatemala, Mexico, and Honduras.
The scrub euphonia is a species of bird in the family Fringillidae.
The mountain trogon, also known as the Mexican trogon, is a species of bird in the family Trogonidae. First described by William John Swainson in 1827, it is resident in Guatemala, Honduras, and Mexico and has occurred in El Salvador as a vagrant. Like all trogons, the mountain trogon is sexually dimorphic. The male is metallic green on the crown, nape, upperparts and chest, the latter separated from its bright red belly and vent by a narrow band of white. The female is warm brown on the head, upperparts and chest, separated from its paler brown lower chest and red belly and vent by a narrow white band.
The rufous-backed robin is a songbird of the thrush family. It is endemic to the Pacific slope of Mexico. It is also known as the rufous-backed thrush.
The western red-tailed hawk is a subspecies of the red-tailed hawk.
The southwestern red-tailed hawk is a subspecies of red-tailed hawk that breeds from northern Chihuahua to southern Texas. It winters in Arizona, New Mexico and southern Louisiana. This seems to be a particularly large subspecies, although its size is not drastically different from the western red-tailed hawk, and, going on average wing size and tarsal length, this appears to be the largest race of red-tailed hawk. The wing chord of males can range from 385 to 402 mm, averaging 393.3 mm (15.48 in), and, in females, it ranges from 425 to 436 mm, averaging 430.7 mm (16.96 in). Additionally, males and females average 210.9 and 223.8 mm in tail length, 88 and 93 mm in tarsal length and 26.3 and 27.5 mm in culmen length. Hybridization seems to occur in eastern Texas with the eastern red-tailed hawk, broadly to the west with B. j. calurus and, possibly, in Nuevo León and Chihuahua with the Mexican Highlands red-tailed hawk. This race combines the darker back of B. j. calurus with the paler underside of B. j. borealis, with the belly band either entirely absent or only manifesting in light streaking. The tail is variable but relatively pale, with some individuals showing almost no dark subterminal band, others having quite a broad subterminal band and some showing extensively barring on top like darker morphs of B. j. calurus.
