  • Positive and negative sources of selection on fruit-eating by birds are discussed. It is hypothesized that fruit is rarely favored as the complete diet for small nestling birds because it results in slower growth rates than those allowed by animal food. Nest predation pressure is greater in totally frugivorous birds and counteracts the advantages of the abundant and easily accessible food supply afforded by fruit. The evolutionary result of total frugivory is discussed, relating population size… CONTINUE READING
