Can conditions experienced during migration limit the population levels of birds?
I Newton - Journal of Ornithology, 2006 - Springer
Populations of migratory birds are usually considered to be limited by conditions in breeding
or wintering areas, but some might be limited by conditions encountered on migration. This …
