Predation and Limitation of Bird Numbers, if not from predation then from something else. For predators to reduce a breeding population below the level that would otherwise occur, at least part of the mortality they inflict must be “additive” to other mortality, and not simply “compensatory,” replacing other forms of death.

Nonbreeding Social Organization in Migratory and Resident Birds,aptiveness of behavior is a threshold to territorial defense that depends on factors such as resource renewal rates (Wolf, 1978; Pyke, 1979; Davies and Houston, 1981) or intruder pressure (Myers .., 1979a; Norton .., 1982; Tye, 1986). Other examples are changes in flocking behavior with predation pr

Sibling Competition, Hatching Asynchrony, Incubation Period, and Lifespan in Altricial Birds, and the significance of variation in synchrony of hatching—and their implications for other aspects of the life history. Among bird species of similar size and developmental state of the neonate, incubation periods vary over a threefold range (Rahn and Ar, 1974). Long incubation periods have puzzle
