Cover at nesting sites selected by breeding birds can reduce the risk of nest predation. Using artificial nests, we tested whether dense cover reduces nest predation upon understory birds (rhinocryptids) in temperate forest ...

Observations on the nesting activities of Microthurge corumbae, carried out at the University Campus of Ribeirao Preto, São Paulo, Brazil, from 1977 to 1981, indicated that 61.9% of nests were re-used by succeeding ...

The breeding biology of the only Scarlet Ibis Eudocimus ruber colony in southeastern Brazil was studied during the 1996-97 breeding season. The ibises began to visit their colony site by mid-September. Nest building and ...

Nine nests of Pachycondyla striata Fr. Smith, 1858 were excavated between 2006 and 2007 at the UNESP university campus in Rio Claro, SP, southeastern Brazil. The P. striata population was larger in the two nests excavated ...

Breeding success and nest-site characteristics were studied during the 1996-1997 breeding season in a colony of Scarlet Ibises Eudocimus ruber in south-eastern Brazil to test the hypothesis that nest-site characteristics ...

In eusocial Hymenoptera, females are more tolerant towards nest-mate than towards non-nest-mate females. In solitary Hymenoptera, females are generally aggressive towards any conspecific female. Field observations of the ...
