Guira cuckoo (Guira guira)

Scientific Classification:

Kingdom : Animalia
Phylum : Chordata
Class : Aves
Order : Cuculiformes
Family :Cuculidae
Genus : Guira
Species : G. Guira

Description:

The Guira cuckoo (Guira guira) is a social, non-parasitic cuckoo found widely in open and semi-open habitats of eastern and southern Brazil, Uruguay, Paraguay, Bolivia, and north-eastern Argentina. It is monotypic within the genus Guira, and is related to the anis.

The species has whitish-buff underparts and rump, dark brownish upperparts, a broadly white-tipped dark tail that is relatively long, an orange-rufous crest, bare yellow ocular-skin (commonly fades in captivity), and a relatively heavy, orange-yellow bill. It is generally rather shaggy-looking and has a total length of approximately 34 cm (13 in). Like other members of the subfamily Crotophaginae, the guira cuckoo gives off a strong, pungent odour.

The guira cuckoo is arboreal, but can frequently be seen on the ground, usually in flocks of 6 to 18 individuals. It is sometimes seen with other birds such as the smooth-billed ani (Crotophaga ani) whose behavior is similar.

Rufous Hornero (Furnarius rufus)

Scientific Classification:

Kingdom : Animalia
Phylum : Chordata
Class : Aves
Order : Passeriformes
Family :Furnariidae
Genus : Furnarius
Species : F. Rufus

Description:

The Rufous hornero(Furnarius rufus) is a medium-sized ovenbird in the family FurnariidaeIt occurs in eastern South America, and is the national bird in Argentina. Also known as the red ovenbird, it is common in savannas, second-growth scrub, pastures and agricultural land and is synanthropic. Its range includes southeastern and southern Brazil, Bolivia, Paraguay, Uruguay and northern and central Argentina, extending as far south as northern Patagonia. The species is most closely related to the crested hornero of Paraguay and Argentina. There are four accepted subspecies.

The rufous hornero is medium-sized with a square tail and very slightly decurved bill. The plumage is overall reddish brown with a dull brown crown and a whitish throat. Sexes are alike and juvenile birds are slightly paler below (probably because they are cleaner). Rufous horneros feed on insects and other arthropods obtained by foraging on the ground while walking. They sometimes feed on scraps such as bread crumbs. Songs in the rufous hornero are sexually distinct. The rapid trill that is usually heard as part of the duet is faster in the male, slower in the female, and both beat their wings at their sides while singing and the wings beat at the same rate as their trill. Thus, while watching an observer may identify the sex by how fast their wings beat while singing.

Predators of adult and young rufous horneros include birds of prey such as the black-chested buzzard-eagle Buteo melanoleucus, small mammals, domestic cats, and a number of species of snakes and possibly lizards. However, its covered nest probably reduces predation risk.

Conservation Status by IUCN:

Status :Vulnerable

A Vulnerable species is one which has been categorised by the International Union for Conservation of Nature as likely to become endangered unless the circumstances threatening its survival and reproduction improve.

Vulnerability is mainly caused by habitat loss or destruction. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity.

Scientific Classification:

Kingdom : Animalia
Phylum : Chordata
Class : Aves
Order : Strigiformes
Family :Strigidae
Genus : Glaucidium
Species : G. Brasilianum

Description:

The Ferruginous pygmy owl(Glaucidium brasilianum) is a small owl that breeds in south-central Arizona in the United States, south through Mexicoand Central America, to South America into Bolivia and Argentina.

In Central America and South America, it is the most widely distributed pygmy owland is probably one of the most numerous owl species in those areas. It is found in a wide range of semi-open wooded habitats in these areas.

This species is crepuscular, but often hunts by day. It hunts a variety of birds, lizards, mammals, and insects. The flight is low to the ground and rapid with long swoops.

It can be readily located by the small birds that mob it while it is perched in a tree (up to 40 birds of 11 species have been recorded mobbing one owl).

The ferruginous pygmy owl is small, typically 15 cm (5.9 in), and stocky with disproportionately large talons. The crown has elongated white/buff spots or streaks, the wing coverts have white spots, and the underparts are heavily streaked white. There are prominent white supercilia above the facial disc. There are two eye spots on the nape.

Otherwise, its overall color is highly variable, ranging from grey-brown with a black-and-white barred tail to rich rufous with a uniform rufous tail. Sexes are similar with females slightly larger and often more reddish.

Great horned owl (Bubo virginianus)

Scientific Classification:

Kingdom : Animalia
Phylum : Chordata
Class : Aves
Order : Strigiformes
Family :Strigdae
Genus : Bubo
Species : B. Virginianus

Description:

The Great horned owl(Bubo virginianus), also known as the Tiger owl (originally derived from early naturalists' description as the "winged tiger" or "tiger of the air") or the Hoot owl, is a large owl native to the Americas. It is an extremely adaptable bird with a vast range and is the most widely distributed true owl in the Americas. Its primary diet appears to be rabbits and hares, rats and mice and voles, although it freely hunts any animal it can overtake, primarily other rodents and small mammals, but also larger mid-sized mammals, various birds, reptiles, amphibians and invertebrates. In ornithological study, the great horned owl is often compared to the Eurasian eagle-owl (Bubo bubo), a closely related species which, despite the latter's notably larger size, occupies the same ecological niche in Eurasia, and the Red-tailed hawk (Buteo jamaicensis), with which it often shares similar habitat, prey and nesting habits by day and is thus something of a diurnal ecological equivalent. The Great horned owl is one of the earliest nesting birds in North America, often laying eggs weeks or even months before other raptorial birds.
