24cm. Identification: it is the only Brazilian thrush with reddish belly. It is the Brazilian Symbol Bird and this title has recently been given for its strong presence in the country’s popular culture, especially in poetry and music. Although it is distributed throughout Brazil (except from the Amazon region ) it is more common near the coastline as it prefers moist environments. This thrush lives in farms, forest edges and is especially common in urban parks, being one of the most typical birds in some of Southeastern Brazil largest cities. The very beautiful song is very variable, even at the individual level.The real song can only be heard in the spring, the breeding season when th...

11,5cm. Identification: there is no other Brazilian species like this bird, at least not in urban and disturbed areas. Formerly all the house wren populations ranging from Canada to Chile were considered as a single species, but after several studies the populations south to Mexico were renamed as the Tropical House Wren (Troglodytes musculus ). This hyperactive bird hops non-stop on the ground in search for the small invertebrates it feeds on, reminding a mouse (musculus = mouse ). It only perches to rest or to sing. Its song is very complex and melodic, like other well known members of the Troglodytidae family. It is famous for the breeding behavior, as this bird may nest in the mos...

Você sabia que insetos podem nos ajudar a resolver investigações criminais? Estes pequenos seres podem ser muito úteis em casos de homicídios ao nos darem pistas sobre há quanto tempo uma vítima foi morta. Mas como extamente isso é feito? Neste vídeo explicamos de forma simplificada como é feito o cálculo do intervalo pós-morte (IPM) com base no ciclo de vida de insetos presentes nos corpos em decomposição.
