Through behavioral observations of a color-banded population of northern mockingbirds, I measured parental defense of offspring against potential predators and feeding of fledglings while renesting. Observations of defense against human intruders acting as potential predators of young showed (1) both males and females defended eggs and nestlings, (2) males defended young more strongly as measured by distance of approach to intruders, proximity of attack dives at intruders, and following intruders to the edge of the territory, (3) male, but not female, defense increased with age of nestlings, (4) levels of defense by males and females were correlated within pairs, and (5) pairs in which males strongly attacked intruders had higher seasonal n...
