Body composition and migration strategies : a comparison between robins (Erithacus rubecula) from two stop-over sites in Sweden
(1992) In Vogelwarte 36(3). p.188-195- Abstract
Robins captured as passage migrants by the Baltic Sea in Sweden at Falsterbo and Ottenby Bird Observatories, respectively, differ with respect to body mass, fat load and orientation behaviour. Relatively more birds with large visual fat deposits are captured at Ottenby than at Falsterbo, but robins at Falsterbo carry more fat than robins at Ottenby. Robins with small fat loads at Ottenby probably consisted of birds which had depleted their fuel reserves during a preceding extensive flight across the Baltic Sea. The difference in fat content, fat-free body mass, flight muscle and liver mass may reflect differences in physiological and ecological conditions for robins migrating mainly over land (arriving at Falsterbo) and over sea...
