WebJun 1, 2005 · Magnetic compass reception in birds appears to be a light dependent process based on antagonistically interacting spectral mechanisms with at least one short-wavelength and one long-wavelength mechanism ( Deutschlander et al., 1999 b) or multiple states of a short-wavelength sensitive mechanism ( Ritz et al., 2000, 2004 ). WebJan 27, 2024 · Although first outbound migration in songbirds is typically, though not universally (), thought to use an inherited clock and compass (vector) navigation program (2–5), additional or alternative mechanisms must be required to account for the accuracy with which birds return to the natal or breeding site (philopatry) (6, 7).Experienced birds …
