The bird assemblage of a southern temperate rainforest on Chiloe Island, southern Chile, was studied during the breeding season of 1993-1994. The modified variable-circular plot method was used to examine the effects on the estimated overall den[...]

Egg type is one factor that is likely to influence the results from artificial nest experiments. Here I document predation rates on Japanese Quail (Coturnix japonica) and the much smaller Zebra Finch (Taeniopygia guttata) eggs on the edge and in[...]

We modified a figure-8 leg-loop harness designed for small passerines to attach successfully 1.8-g radio transmitters over the synsacrum of migrant Soras (Porzana carolina). Because of the short caudal region of Soras, addition of a waist loop w[...]

I provide a detailed description of an arthropod sampling technique, "branch clipping," and evaluate its efficacy in measuring food availability for three foliage-gleaning migratory warbler species wintering in Jamaica. I incorporated foraging o[...]
