- Title
Bromeliad density correlates with territories in a cooperatively breeding wren, the Band-backed Wren ( Campylorhynchus zonatus).

- Abstract
In many species of animals, the distribution of critical resources underlie the pattern of the animals themselves. However, in areas of apparently abundant resources, it is not clear which resources, if any, are limited. I investigated a possible limitation for a cooperatively breeding wren living in lowland tropical rainforest. I found that the composition of epiphytic foraging substrates, especially the abundance of bromeliads, correlated with the distribution of wren habitation, and were heavily foraged upon. High densities of these bromeliads were found only in gallery forests, suggesting that areas of high bromeliad density may be a limiting factor in dispersal in Band-backed Wrens ( Campylorhynchus zonatus).
