Abstract

To the general rule that the struggle for existence among plants and animals is sharper and more exacting in the tropics than in cooler parts of the earth, birds form no exception. Moreover, so far at least as the region we are about to consider is concerned, the unfavorable or hostile elements in the environment of tropical birds differ greatly in kind or in proportion from those that must be provided against by birds of temperate climates. We should, therefore, expect to find a strongly marked difference between the habits, particularly the breeding habits, of the birds of the two regions; and this is actually the case.
