| الوصف: | Liechti, Felix/0000-0001-9473-0837 ; WOS: 000595749100009 ; For migratory birds optimal timing of the onset of reproduction is vital, especially when suitable conditions for reproduction occur only for a short while during the year. With increasing latitude the suitable period becomes shorter and we expect the organization of annual cycle to be more synchronized to the local conditions across individuals of same population. This should result in low variation of arrival and departure date in breeding sites at higher latitudes. We quantify the temporal and geographical variation in pre- and post-breeding migration between individuals from four different populations of alpine swifts Tachymarptis melba along a latitudinal gradient. We tracked 215 individuals in three years with geolocators. The two western and two eastern populations showed separate migratory flyways and places of residence in Africa. Length of stay at the breeding sites was negatively correlated with latitude and differed by more than a month between populations. Duration of migration was similarly short in all populations (median 6.2 days in autumn and 8.7 days in spring). However, variation in timing of migration was unrelated to latitude and individuals everywhere arrived in the same asynchrony at the breeding site. ; Swiss federal office for the environment (FOEN) [UTF 400.34.11]; Wolfermann-Nageli foundation ; The Swiss federal office for the environment (FOEN) contributed financial support for the development of the tags (grant UTF 400.34.11). The Wolfermann-Nageli foundation granted supported for fieldwork. |
