Variations in Black Guillemot Cepphus grylle natal dispersal and philopatry across Britain and Ireland
Using ring recovery records collected in Britain and Ireland from 1935 to 2015, we investigated philopatry and dispersal in Black Guillemots Cepphus grylle ringed as nestlings and recovered at breeding age during the breeding season. Levels of philopatry and dispersal distance varied between colonie...

Summary: | Using ring recovery records collected in Britain and Ireland from 1935 to 2015, we investigated philopatry and dispersal in Black Guillemots Cepphus grylle ringed as nestlings and recovered at breeding age during the breeding season. Levels of philopatry and dispersal distance varied between colonies, and were significantly related to latitude, possibly due to differences in ecology between populations. However, an increase in ringing effort is required to allow robust comparisons of these behaviours between colonies. |
