Seasonal use of habitat by shrub-breeding birds in a southeastern national forest

摘要: Abstract Populations of shrub-breeding birds are declining in eastern North America, and loss habitat has been implicated these declines. Seasonal use by the southeastern US remains understudied despite fact that it is well documented species resident within a region can shift dramatically between seasons. To better understand year-round occupancy birds, we conducted bird counts vegetation surveys during summer winter 2008–2009 Tuskegee National Forest, Alabama. We used multi-season models to examine contrast seasonal patterns four birds—Brown Thrashers (Toxostoma rufum), Eastern Towhees (Pipilo erythrophthalmus), Northern Cardinals (Cardinalis cardinalis) Carolina Wrens (Thryothorus ludovicianus). Brown partially migratory—meaning some populations have separate breeding wintering are...
