The purple finch (Haemorhous purpureus)

The purple finch (Haemorhous purpureus) is a bird in the finch family, Fringillidae.

This species and the other “American rosefinches” are placed in the genus Haemorhous by the American Ornithologists’ Union but have usually been included in Carpodacus. It is included in the finch family, Fringillidae, which is made up of passerine birds found in the northern hemisphere and Africa. The purple finch was originally described by Johann Friedrich Gmelin in 1789.

There are two subspecies of the purple finch, H. p. purpureus and H. p. californicus. H. p. californicus was identified by Spencer F. Baird in 1858. It differs from the nominate subspecies in that it has a longer tail and shorter wing. The plumageof both males and females are darker, and the coloration of the females is more greenish. The bill of C. p. californicus is also longer than that of the nominate subspecies.

Adults have a short forked brown tail and brown wings and are about 15 cm (5.9 in) in length and weigh 34 g (1.2 oz). Adult males are raspberry red on the head, breast, back and rump; their back is streaked. Adult females have light brown upperparts and white underparts with dark brown streaks throughout; they have a white line on the face above the eye.

Their breeding habitat is coniferous and mixed forest in Canada and the northeastern United States, as well as various wooded areas along the U.S. Pacific coast. They nest on a horizontal branch or in a fork of a tree.

Birds from northern Canada migrate to the southern United States; other birds are permanent residents.

The purple finch population has declined sharply in the East due to the house finch. Most of the time, when these two species collide, the house finch outcompetes the purple finch. This bird has been also displaced from some habitat by the introduced house sparrow.

These birds forage in trees and bushes, sometimes in ground vegetation. They mainly eat seeds, berries and insects. They are fond of sunflower seeds, millet, and thistle.

This is the state bird of New Hampshire.

spotted antbird (Hylophylax naevioides)

The spotted antbird (Hylophylax naevioides) is a species of bird in the Thamnophilidae family. In southern Central America, it is found in Honduras, Nicaragua, Costa Rica and Panama; also Colombia and Ecuador of northwestern South America. Its natural habitat is subtropical or tropical moist lowland forests.

A smallish bird, measuring 11 cm (4.3 in) and weighing 16–19.5 g (0.56–0.69 oz). The male spotted antbird’s plumage is a distinctive combination of large black spots on a white chest, chestnut back, grey head with black throat. The female is dull, but also distinctive with large chest spots and two wide buffy wing-bars.

Forages as individuals or pairs in lower levels of mature, humid forests. Found in lowlands and foothills up to 1,000 m (3,300 ft).
Spotted antbirds are known to follow army ant swarms to catch insects and other small animals trying to flee. They eat spiders, scorpions, cockroaches, katydids, crickets, centipedes, sowbugs, moths, beetles, caterpillars, ants, bristletails and, on occasion, lizards and frogs.

This bird is an open-cup nesting species that lays an average clutch of 2 maroon-splotched white eggs, which both adults incubate. The nestling period is 11 days.

green violetear (Colibri thalassinus)

green violetear (Colibri thalassinus) is a medium-sized, metallic green hummingbird species commonly found in forested areas from Mexico to northern South America.

The green violetear belongs to the order Apodiformes. Hummingbirds share this order with the swifts, such as the white-collared swift. The name Apodiformes is derived from the Greek words “a pous,” meaning “without foot.” While apodiforms do in fact have feet, they are quite small and their legs are short and relatively weak. Many birds in this order cannot walk, and thus rarely if ever land on the ground since quick escape from predators is virtually impossible. For this reason members of this order spend a majority of their time in the air.
