Magnetic compass of migratory Savannah sparrows is calibrated by skylight polarization at sunrise and sunset

Rachel Muheim, Auteur ; Susanne Åkesson, Auteur ; John B. Phillips, Auteur

Dans Journal of Ornithology (148 DEC 2007)

Migratory birds use compass systems derived from the geomagnetic field, the stars, the sun and polarized light patterns. We tested whether birds use a single underlying reference system for calibration of these compasses and, specifically, wheth[...]

Naive migrants and the use of magnetic cues: temporal fluctuations in the geomagnetic field differentially affect male and female Ruff Philomachus pugnax during their first migration

Eldar Rakhimberdiev, Auteur ; Julia Karagicheva, Auteur ; Kim Jaatinen, Auteur ; David W. Winkler, Auteur ; John B. Phillips, Auteur ; Theunis Piersma, Auteur

Dans Ibis (156(4) OCT 2014)

In many species, naive first-time migrants undertake migration without adults, supposedly on the basis of a simple' vector programme that combines an innate directional preference with a temporal programme that specifies distance. In strongly di[...]
