Snowy egret (Egretta thula)

Scientific Classification:

Kingdom : Animalia
Phylum : Chordata
Class : Aves
Subclass : Neornithes
Infraclass : Neognathae
Superorder : Neoaves
Order : Pelecaniformes
Family :Ardeidae
Genus : Egretta
Species : E. Thula

Description:

The Snowy egret(Egretta thula) is a small white heron. It is the American counterpart to the very similar Old World little egret, which has established a foothold in the Bahamas. At one time, the beautiful plumes of the snowy egret were in great demand by market hunters as decorations for women's hats. This reduced the population of the species to dangerously low levels.[citation needed] Now protected in the United States by law, under the Migratory Bird Treaty Act, this bird's population has rebounded.

Adults are typically 61 cm (24 in) long and weigh 375 g (0.827 lb) They have a slim black bill and long black legs with yellow feet. The area of the upper bill, in front of the eyes, is yellow but turns red during the breeding season, when the adults also gain recurved plumes on the back, making for a "shaggy" effect. The juvenile looks similar to the adult, but the base of the bill is paler, and a green or yellow line runs down the back of the legs.

Snowy Egrets nest in colonies on thick vegetation in isolated places—such as barrier islands, dredge-spoil islands, salt marsh islands, swamps, and marshes. They often change location from year to year. During the breeding season Snowy Egrets feed in estuaries, saltmarshes, tidal channels, shallow bays, and mangroves. They winter in mangroves, saltwater lagoons, freshwater swamps, grassy ponds, and temporary pools, and forage on beaches, shallow reefs, and wet fields.

ANIMALS - BIRDS - FLAMINGOS - CHILEAN FLAMINGO (PHOENICOPTERUS CHILENSIS)

Animals - Birds - Flamingos

Chilean flamingo (Phoenicopterus chilensis)

Scientific Classification:

Kingdom : Animalia
Phylum : Chordata
Class : Aves
Order : Phoenicopteriformes
Family :Phoenicopteridae
Genus :Phoenicopterus
Species : P. Chilensis

Description:

The Chilean flamingo(Phoenicopterus chilensis) is a large species of flamingoat 110–130 cm (43–51 in)closely related to American flamingo and greater flamingo, with which it was sometimes considered conspecific.

It breeds in South America from Ecuador and Peru to Chile and Argentina and east to Brazil; it has been introduced into Germany and the Netherlands (colony on the border, Zwilbrockervenn). There is also a small population in Utah and California. Like all flamingos it lays a single chalky white egg on a mud mound.

The plumage is pinker than the slightly larger greater flamingo, but less so than Caribbean flamingo. It can be differentiated from these species by its greyish legs with pink joints (tibio-tarsal articulation), and also by the larger amount of black on the bill (more than half). Young chicks may have no sign of pink coloring whatsoever, but instead remain grey.

Binomial Name:

Name : Phoenicopterus chilensis
Taxonomist : Juan Ignacio Molina (Guaraculén, Chile)
Year : 1782
Subspecies : None or not data available
Synonyms : None or not data available

Conservation Status by IUCN:

Status :Near-threatened species

A Near-threatened speciesis a species which has been categorized as "Near Threatened" (NT)by the International Union for Conservation of Nature as that may be considered threatened with extinction in the near future, although it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxa at appropriate intervals.

Animals - Birds - Owls

Burrowing owl (Athene cunicularia)

Scientific Classification:

Kingdom : Animalia
Phylum : Chordata
Class : Aves
Order : Strigiformes
Family :Strigdae
Genus :Athene
Species : A. Cunicularia

Description:

The Burrowing owl(Athene cunicularia) is a small, long-legged owl found throughout open landscapes of North and South America. Burrowing owls can be found in grasslands, rangelands, agricultural areas, deserts, or any other open dry area with low vegetation. They nest and roost in burrows, such as those excavated by prairie dogs (Cynomys spp.). Unlike most owls, Burrowing Owls are often active during the day, although they tend to avoid the midday heat. But like many other kinds of owls, burrowing owls do most of their hunting from dusk until dawn, when they can use their night vision and hearing to their advantage. Living in open grasslands as opposed to the forest, the burrowing owl has developed longer legs, which enables it to sprint as well as fly when hunting.

Binomial Name:

Name : Athene cunicularia
Taxonomist : Juan Ignacio Molina (Guaraculén - Chile)
Year : 1782
Subspecies : Around 20 (Cunicularia, Grallaria, Hypugaea, … )
Synonym : Strix cunicularia, Speotyto cunicularia, Spheotyto cunicularia (lapsus)

Conservation Status by IUCN:

Status :Least Concern

Has been categorized by the International Union for Conservation of Nature as evaluated but not qualified for any other category. As such they do not qualify as threatened, near threatened, or (prior to 2001) conservation dependent.
