No difference in chick-provisioning by bridled and non-bridled Common Guillemots Uria aalge
Abstract Despite recent evidence that bridled Common Guillemots Uria aalge may depend more on cold-water prey species than non-bridled, there was no morph-specific difference in the species composition or size of fish caught for chicks by adults in a North Norwegian colony. This supports the recent...

Summary: | Abstract Despite recent evidence that bridled Common Guillemots Uria aalge may depend more on cold-water prey species than non-bridled, there was no morph-specific difference in the species composition or size of fish caught for chicks by adults in a North Norwegian colony. This supports the recent suggestion that selection pressure on the morphs acts in the non-breeding season, rather than in summer. |
