The effects of rainfall and arthropod abundance on breeding season of insectivorous birds, in a semi-arid neotropical environment

Rainfall in tropical semi-arid areas may act as a reliable cue for timing bird reproduction, since it precedes future food supply.With this in mind, we set-up a study to test the reproductive response of insectivorous bird to arthropod abundance and rainfall patterns.Sampling occurred in a seasonally dry Neotropical forest, in north-eastern Brazil,
