Clay-colored Sparrow

The Clay-colored Sparrow, Spizella pallida, is a small, slender New World sparrow in the family Passerellidae that breeds across the central prairies and boreal forest edges of North America, from the Great Plains of the United States northward through the Canadian prairies to the Northwest Territories. The species winters in Mexico, particularly in the Chihuahuan Desert grasslands and scrublands. It is a bird of open, brushy habitats, showing a preference for shrubby grasslands, weedy fields, overgrown pastures, and the shrubby understory of young conifer and aspen forests. Clay-colored Sparrows are recognized by their clean buffy-brown plumage, strongly patterned face with a distinctive brown cheek patch bordered by white stripes, and the characteristic brown crown stripes. The male's song is an insect-like series of flat buzzes, delivered persistently from elevated shrub perches. The species feeds primarily on grass seeds and weed seeds, supplemented during the breeding season with insects and other invertebrates used to provision nestlings. Breeding pairs construct cup-shaped nests low in shrubs. The Clay-colored Sparrow is considered a species of Least Concern with a large and relatively stable population across its extensive North American range.

Polar bear

O maior carnivoro terrestre da Terra, o urso-polar pode ultrapassar 700 kg e e encontrado pelo gelo marinho artico, do Canada ate a Russia. Mamiferos marinhos altamente especializados que dependem do gelo marinho para cacas de focas e focas-barbadas. Excelentes nadadores capazes de percorrer grandes distancias em aguas abertas. Classificado como Vulneravel, com populacoes sob severa pressao devido a rapida perda de gelo marinho artico causada pelas mudancas climaticas.
