Behavioral barriers to non-migratory movements of birds
Although effects of physical barriers to animal movement are well established, the behavioral inhibition of individuals moving across habitat gaps, ecotones, and interpatch (matrix) habitat has received little attention. Birds are often cited as a taxon in which movements should not be disrupted by gaps in landscape connectivity. Here we synthesize evidence from the literature for behavioral in...

sions about site settlement on both breeding and nonbreeding grounds. Each year a fraction of surviving individuals return to sites occupied in previous years. The accumulation of capture histories, and the widespread distribution of capture–recapture software to analyze such data (Lebreton et al. 1992) have lead to a proliferation of estimates of apparent annual survival rates for migratory bi...
متن کاملSerological Monitoring of Avian Influenza in Migratory Birds of Iran
Although migratory waterfowl is well known to be a major reservoir for avian influenza virus (AIV), there are only few recently published reports about the seroprevalence of AIV in this group of birds. To investigate the AIV antibody status in migratory waterfowl of Iran, we collected 217 serum samples from 25 different species of waterfowl during 2003 and 2004. These serum samples were teste...
متن کاملBirds as predators in tropical agroforestry systems.
Insectivorous birds reduce arthropod abundances and their damage to plants in some, but not all, studies where predation by birds has been assessed. The variation in bird effects may be due to characteristics such as plant productivity or quality, habitat complexity, and/or species diversity of predator and prey assemblages. Since agroforestry systems vary in such characteristics, these systems...
