Individual quality and age affect responses to an energetic constraint in a cavity-nesting bird
Individual variation in life-history trade-offs can be caused by differences in quality and age. We tested for individual variation in parental investment in incubating tree swallows (Tacyhcineta bicolor) subjected to a feather-clipping manipulation. Individual quality influenced how females were affected by feather clipping; lower quality clipped females showed a greater reduction in incubatio...
متن کاملResponse to Chemical Cues From A Predator In A Cavity - Nesting Bird
Birds have long been considered to have poor senses of smell, but recent studies have shown differential behavioral reactions to various scents in songbirds. Predator detection via olfaction may be particularly important in cavity nesters because predators could trap them or ambush them from within the cavity. We examined the response of House Wrens (Troglodytes aedon), a common, cavity-nesting...
متن کاملLack of Nest Site Limitation in a Cavity-nesting Bird Community
We examined the relationship between nest site availability and density of secondary cavitynesting birds by blocking cavities in an oak-pine (Quercus spp.-Pinus sp. ) woodland. I n 1986 and 1987 we blocked 67 and 106 cavities, respectively, on a 37-ha plot. The combined density of secondary cavity-nesting birds did not decline in either year by a greater proportion on the treatment plot than on...
متن کاملPhysical habitat quality and interspecific competition interact to influence territory settlement and reproductive success in a cavity nesting bird
*Correspondence: John A. Jones, Biology Department, Appalachian State University, 572 Rivers Street, Boone, NC 28608-2027, USA e-mail: [email protected] Determining how to best measure habitat quality is essential for many conservation plans and basic ecological questions. Territory quality is thought to be a product of physical habitat characteristics (i.e., habitat quality) and the densit...
متن کاملImmunity and Virulence in Bird-Parasite Interactions
The interaction between hosts and parasites is characterized by the evolution of reciproca adaptations aiming at reducing the cost of infection (from the host point of view) and to optimize host exploitation (from the parasite point of view). Within this co-evolutionary scenario, the immune system takes a central role. The immune system has evolved to fight off parasitic attacks. However, immun...
