Rapid microevolution of migratory behaviour in a wild bird species
THE Blackcap, Sylvia atricapilla, a widespread Palearctic migratory bird, rarely wintered in Britain until the 1950s. The winter population has since increased to several thousand birds1,2. RingingExpand

Heritability of the timing of autumn migration in a natural bird population
In recent decades, global temperature has increased at an unprecedented rate. This has been causing rapid environmental shifts that have altered the selective regimes determining the annualExpand

25-Year Study of the Population Development of Central European Songbirds: A General Decline, Most Evident in Long-Distance Migrants
During the past century a decline hasbeen noted in European bird popula-tions, both in large species [1] andpossibly also in songbirds [2]. Todaythe “Red List” (of endangered spe-cies) includes aboutExpand

Genetic transmission of migratory behavior into a nonmigratory bird population
Crossbreeding experiments with blackcaps from a nonmigratory population (of the Cape Verde Islands) and a migratory population (from southern Germany) demonstrated that the urge to migrate as well asExpand

Inheritance of a novel migratory direction in Central European blackcaps
described above differ markedly from those of all avian species studied to date [2]. Most notable is the panoramic nature of vision beneath the bill. We propose that this feature is closelyExpand
