Caracterização de ninhos de Acromyrmex laticeps nigrosetosus Forel, em povoamento de eucalipto em Paraopeba, MG Anais da SEB
Araújo,Márcio S.; Della Lúcia,Terezinha M. C..
The nesting habits of the leaf-cutter ant Acromyrmex laticeps nigrosetosus Forel were studied in areas under Eucalyptus plantations in Minas Gerais State, Brazil. A total of 12 nests were killed with methyl bromide and talcum was injected into entrance holes with a small air pump to mark the underground chambers and channels. In general, these nests presented a single chamber with average dimensions of 0.28 x 0.23 x 0.19 m (length x width x height) located just below the soil surface (0.11 m). Chambers were connected to the soil surface by 2-5 channels which opened at the surface. Externally they were covered by a large amount of dry leaves and in their early stage presented a mound of loose soil. The total nest population was, on average, 12,231...

Bird-termite interactions in Brazil: A review with perspectives for future studies Biota Neotropica
de Vasconcelos,Marcelo Ferreira; Hoffmann,Diego; de Araújo,Mércia Caroline; Vasconcelos,Prinscila Neves.
We present a review on the principal interactions between birds and termites in Brazil. We found 218 bird species feeding on termites or using termitaria for nesting or perching. Termites were mentioned as food source for 179 bird species. Alates were the most consumed caste. Termitaria were mentioned as nest site for 45 bird species. Some bird species also perch on the top of termite mounds to search for their prey or to conduct territorial and/or courtship displays. Considering all interactions between both animal groups, little is known about the identification of termite genera or species. Therefore, we suggest more detailed studies to be conducted on the natural history and ecology of interactions between birds and termites in Brazil.

Nest architecture of the stingless bee Geotrigona subterranea (Friese,1901) (Hymenoptera: Apidae: Meliponini) Biota Neotropica
Barbosa,Fernando Mendes; Alves,Rogério Marcos de Oliveira; Souza,Bruno de Almeida; Carvalho,Carlos Alfredo Lopes de.
We located ten nests of Geotrigona subterranea in the transition area between Cerrado and Caatinga within the municipalities of Lontra and Januária, state of Minas Gerais, southeastern Brazil. We collected the nests to study their architecture in detail. In the present paper, we describe the general nest structure of this bee species in terms of: number, shape and area of the combs; size of the brood cells; size of honey and pollen pots; volume of honey and mass of pollen stored in closed pots; presence of inquiline species; and defensive characteristics. All nests were found in subterranean cavities. The nest structure of G. subterranea is similar to that of other congeneric species.

Nesting behavior of the Picazuro Pigeon, Columba Picazuro (Columbidae, aves) BJB
ONIKI,Y.; WILLIS,E. O..
The Picazuro Pigeon nests in all months of the year in southeastern Brazil. Nest material is plucked from trees or ground and carried to build a frail and transparent nest of sticks where one egg is laid. Female and male alternate in incubation and brooding and do not soil the nest with feces.

Nesting behavior of the swallow-tailed hummingbird, Eupetomena macroura (Trochilidae, aves) BJB
ONIKI,Y.; WILLIS,E. O..
An August or winter nestling of Eupetomena macroura was fed only every 40-50 min for at least 24 days in the nest, with fewer feedings at midday. As in other hummingbirds, it was brooded only the first week or two, and left alone even on cool nights after 12 days, probably due to the small nest size. The female attacked birds of many non-nectarivore species near the nest, in part probably to avoid predation. Botfly parasitism was extremely high, as in some other forest-edge birds.
