Sexual size dimorphism can result in reduced competition if it leads males and females to use different foraging techniques or consume different prey items. Among woodpeckers, differences between males and females in bill length are common and m[...]

In Florida, habitats that include the breeding territories of Crested Caracaras (Caracara cheriway) are protected, but non-breeding individuals may be vulnerable because they may occupy different areas and habitats. We captured and radio-tagged [...]
