Sample text

Comparing the costs of reproduction between Hooded Warblers and Dusky Antbirds is like comparing apples and bananas. Tropical birds do not have low reproductive effort just because clutch size is smaller. There is good evidence for immediate (rather than future) tradeoffs: low food availability for young, high nest predation, and limited opportunities for young to obtain good territories all favor small clutch size. Unlike temperate zone birds, tropical birds appear to lay as many eggs as they can successfully raise.

Few studies have attempted to measure the cost of reproducing in tropical birds. Tropical House Wrens whose brood was increased by two young laid fewer eggs later that year and the next breeding season, but did not suffer decreased survival (Young 1996). Green-rumped Parrotlet females could raise large broods that were manipulated to hatch synchronously without any decrease in adult survival or future reproductive success (Stoleson and Beissinger 1997). Both these species have relatively large clutch sizes, so perhaps the costs of reproduction would be higher for species with the more typical clutch of two or three eggs.

Even in frugivorous birds, nestlings are often fed arthropods early in their development (Morton 1973). Many frugivores breed during the dry season when arthropod abundance is low, and male parental care may be crucial only for a few days when nestlings cannot survive on fruit alone. This could be tested with temporary male removal experiments in a species like the Claycolored Robin where starvation in nestlings is common even when both parents are feeding (Chapter 3). 5 BEHAVIORAL ECOLOGY OF TROPICAL BIRDS Cooperative breeding Cooperative breeding, where many individuals can assist a single pair in breeding or breed together themselves, lies at the other extreme of sociality from promiscuous species.
