Physical appearance: 40 cm. The feet are red and webbed. The chest is brown, as well as the face that is a bit darker. There is a patch of iridescent feathers in the wings. When flying it shows a large white spot at the back of the wing. The male has a red beak and the female’s is blue. The Female also has white spots on the face. Distribution: From Venezuela to Argentina. Habitat: Wetlands, lakes, ponds and rivers even in polluted places. Diet: Feeds on seeds, leaves and small invertebrates. The hatchlings are goot at catching insects. Reproduction: Lays up to 14 bluish or greenish eggs. When the adult realizes the presence of a potential predator it distracts its attention...

62 cm in length, 143 cm of wingspan. The feathers are absent in the head and neck. The body is black, with white spots near the tip of the wings (seen only when flying). Distribution: From central U.S.A to central Argentina. Habitat: Virtually in any kind of landscape, preferably in open areas. Absent in large areas of dense vegetation. Diet: Mainly carrion. Does not hunt, but kills injured or young animals, such as turtle eggs and hatchlings, even newly born big mammals like calves. May eat fruits. The excellent eyesight helps finding carrion at long distances. Reproduction: The courtship consists of movements of the male jumping on the ground with the wings opened and then...

15cm Identification: it is one of the largest hummingbirds. It is easily identified by the forked tail, reminding a pair of scissors. Unmistakably Brazilian’s best known hummingbird, this magnificent animal is also one of the most belligerent ones. It fiercely defends its territory – usually consisting of a flowering patch – against other birds, especially the bananaquit ( Coereba flaveola ). It sucks sweet water from feeders even if these are place in the interior of the houses, fearlessly entering the rooms. Like other hummingbirds it feeds mostly on nectar but also on insects. The female lays 2 or 3 eggs in a small bow-shaped nest and feeds the nestlings mainly with arthropods.

19 cm. The body is brown, darker in the back and ferruginous in the tail. The ventral part is light brown. Distribution: Northeast, Mideast to South of Brazil, also in Argentina, Paraguay, Uruguay and Bolivia. Has been spreading its distribution along with deforestation. Habitat: Open landscapes, fields, cerrado, lawns and gardens. Diet: Mainly arthropods, sometimes seeds. Reproduction: The couple builds the nest with mud, manure and straw that they carry with their beaks and model with their feet. The nest is usually built on tall trees. Each year a new nest is built, sometimes over the previous ones (up to 11 nests one above the other). The nest has two divisions and the eggs...

Mideastern Brazil. Migrates seasonaly in southern Brazil. Habitat: Open fields, grasslands, grazing lands and parks in urban areas. Diet: Catches insects on the ground and sometimes in trees. Follows cattle to feed on insects displaced by its movement. Reproduction: Builds a nest made of branches about 4m from the ground. May use nests abandoned by the hornero (Furnarius rufus). The white eggs are incubated by the couple. Natural history: When on the ground runs for some meters then stops t...

25 cm. The upper parts are brown, the inferior light brown. There are white wingbars . The supercilium and the edging of the tail are white. Male and female are similar. Distribution: South of Amazon to Paraguay, Uruguay, Argentina and Bolivia. Habitat: Open areas with some trees or scrubs, cerrado, caatinga (Brazilian scrubland) and urban areas. Diet: Feeds on insects and spiders caught on the ground. Also eats small fruits and seeds. Sometimes prey on other bird’s eggs. Reproduction: The nest is built about 1,5m from the ground on a small tree or scrub. The external part is made of thick branches and the interior of thin roots and grass. It may have up to four broods a year, eac...

18,5 cm. The body is gray, slightly blue with the inferior parts lighter. The tail and the tips of the wings are blue, somewhat green. There is a spot of this color in the shoulders. Male and female are similar. Distribution: Mideast Brazil from Maranhão to Rio Grande do Sul, also in Venezuela, Colombia, Bolivia, Argentina, Paraguay and Uruguay. Habitat: Lives on trees, either in open areas, parks or cities. Diet: Feeds on fruits, leaves, buds, nectar including from eucalyptus trees. Also catches flying insects as butterflies and termites. Reproduction: During the breeding season the male exhibits its shoulders to the female. The nest is built by the couple and is a compact open...

60 a 70 cm. The top of the head, the back and the wings are black and the other parts of the body are mostly grey. The immature is brown and striated. Distribution: All over the world, except from the poles and Australia. Habitat: Slow flowing rivers, lakes, reservoirs and swamps. Diet: Aquatic insects, mollusks, crustaceans, fish, amphibians and reptiles. May also eat carrion and rests of food fallen from other bird’s nests, including dead hatchlings. Reproduction: Breeds in colonies together with other species of herons. The nests are built from 1 to 7m from the ground or water. Lays two or three bluish green or buffy eggs. Natural history: During most of the day it rests...

Just like other seedeaters, it is practically impossible to tell this species apart from the brownish females, virtually identical to the other seedeaters’ females. Nevertheless the males present the chest and the head in black, the upper parts dark brown and the belly is yellow or beige. Its behavior is very similar to other seedeaters and may form mixed groups with other species when not breeding. It is less urban than the Double-collared and the Lined Seedeaters, being more common in grasslands and grain crops. May be raised as a cage bird. In the breeding season the couples split from the groups. The nest is a low bow made of grasses and the female usually lays 2 or 3 eggs.

There is still some debate on this bird’s taxonomic status. The Brazilian Official Bird List considers two species, the Suiriri Flycatcher, with two subspecies, the Chaco Suiriri, and the Campo one, which differs from the previous for having a yellowish rump, instead of grayish, and there is the recently described Chapada Suiriri ( Suiriri islerorum ), similar to the Campo one (possibly hybridizing with it) but with a smaller beak and white in the tip of the tail. Very little is known about this species. It is mostly solitary and uses the same hunting techniques of most other flycatchers, that consist basically of catching flying insects few meters away from its perching site and returni...

15 cm. The male is dark grey with the top of the head black. There are white spots in the tip of the tail’s feathers and in the wings, in a pattern that is similar to other antshrikes. The female is brown. Distribution: From Peru and Bolivia to Uruguay. Absent in most of the Amazon. Habitat: Mostly in Forest borders, gallery and secondary forests. Diet: Arthropods. Beats the wings to shake the foliage, catching the insects that are scared. Reproduction: The male offers the female some food before mating. The couple builds a nest with stems and moss. The female lays three white eggs with red dots. Generally the male incubates during the day and the female in the night. The paren...

23cm. The beak is dark, the wings ferruginous and the throat from white to light brown with faint streaks. The inferior parts are pale, sometimes white. Distribution: From Venezuela to Argentina and Paraguay. Mideast and South of Brazil. Habitat: Secondary forests, woods, gallery forests and cities, provided there are enough trees. Diet: Feeds on fruits, seeds, arthropods and earthworms. Reproduction: The female builds the nest with sticks and mud. It is usually placed in a palm tree or on walls. The male helps feeding the brood (generally three). Natural history: The name “sabiá” in Portuguese comes from Tupi (an indian language) and means “the one who prays” and is related...

32 cm. The body is green. There is a red and yellow area below the wings. There is a pale area around the eye. The male’s body and beak are stronger than the female’s. The beak is light brown in the immature individuals. Distribution: From the Guyanas to Argentina. Habitat: Forest borders, cerrado, woods and parks in cities. Diet: Feeds on buds, leaves, flowers, seeds, fruits and sometimes insects. Reproduction: Builds a nest inside holes in trees or rocks, witnessed by the author building a nest inside a hole in the old wall of a building. Lays three or four white eggs, incubated by the female that is fed by the male during this period. The couple feeds the brood. May learn some...

Infográfico voltado para o público infantil mostrando as fases do desenvolvimento de um inseto com desenvolvimento holometábolo

A ocorrência de uma reação química é indicada pelo aparecimento de novas substâncias ou pelo menos uma diferente das que existiam antes. Existem reações químicas que ocorrem sem que sejam percebidas, pois nenhum fato é registrado visualmente. Entretanto, algumas reações deixam clara a sua ocorrência, pois percebemos algumas mudanças tais como: desprendimento de gás e de luz, mudança de coloração e cheiro, formação de precipitado (ppt), mudança de temperatura...

A energia, no panorama mundial atual, tornou-se uma peça essencial para o crescimento dos países. Grande parte da energia utilizada emana de fontes fósseis, principalmente do petróleo, portanto, tornam-se cada vez mais significativas as pesquisas e o desenvolvimento de novas fontes alternativas de energia, realçando a preocupação com os parâmetros sustentáveis. Assim como há uma preocupação com a escassez do petróleo e com o desenvolvimento de alternativas sustentáveis para produção de energia, observa-se também outro problema que aflige a todos: o aquecimento global e seus impactos no clima, no bem-estar e saúde dos seres vivos. O aquecimento global é um fenômeno natural do planeta, mas vem...
