Barred Antshrike ( Thamnophilus doliatus )

16cm. Identification: The male is practically unmistakably recognized for the fully barred body and a black crest in the head. The female is ferruginous and has a crest and is barred in the head. It is currently the only antshrike which lives in really urban and disturbed areas. It is worth reminding that this bird has only recently conquered the urban environment. In the early 80s the first records of this antshrike in large cities were so unexpected that they yielded notes in scientific papers. Like other antshrikes it lives in couples, leaping and flying from branch to branch, usually through the short trees’ canopy in search for the small arthropods it feeds on. In the breeding seas...

FUNGOS CONIDIAIS ASSOCIADOS A FOLHAS EM DECOMPOSIÇÃO DE Clusia melchiori Gleason e C. nemorosa G. Mey EM FRAGMENTO DE MATA ATLÂNTICA, BAHIA, BRASIL

Os fungos conidiais constituem um grupo diversificado, com cerca de 15.945 espécies. Contudo, pesquisas taxonômicas sobre esses fungos no Brasil permanecem escassas e pontuais abordando, sobretudo, os decompositores de substratos vegetais. A Serra da Jibóia, fragmento de Mata Atlântica inserido na Caatinga do Estado da Bahia, foi selecionada como prioritária para conservação da biodiversidade. Visando contribuir para o conhecimento dos fungos conidiais na área, folhas em decomposição de três indivíduos de Clusia nemorosa, e C. melchiori foram coletadas bimestralmente de outubro/2005 a junho/2006. No laboratório, as folhas foram lavadas, colocadas em câmara-úmida e os fungos identific...

Little Nightjar ( Caprimulgus parvulus )

Length: 20cm Identification: nightjars are always very difficult to identify as they are nocturnal birds, rarely seen during the day due to their camouflage.
