Brood parasitism: a good strategy in our changing world?

ABSTRACT: The original life-history strategy of brood-parasitic birds has been the focus of a large number of studies in ecology and evolution. Whether species adopting such a strategy differ in their response to global changes remains, however, unknown. Both the absence of investment in parental care and the capacity to spread nesting failure by laying eggs in several nests might help brood parasites in dealing with environmental changes. Alternatively, brood parasites might cumulate the negative effects of environmental changes on their own environment and on their hosts' environment. Here, I tested whether brood parasites' extinction risk and population trend differed from those of species with parental care. Focusing on the five bird families containing brood parasite species, I show that brood
