Does Day Length Affect Winter Bird Distribution? Testing the Role of an Elusive Variable
Differences in day length may act as a critical factor in bird biology by introducing time constraints in energy acquisition during winter. Thus, differences in day length might operate as a main determinant of bird abundance along latitudinal gradients. This work examines the influence of day lengt...
