摘要：

Juvenile little blue herons (Florida caerulea) miss prey more frequently and capture less food per minute foraging than do adults. The inefficiency of juveniles in capturing prey is an adequate explanation for the deferment of reproduction beyond the time when the birds might first be expected to breed. © 1969.
