The incentive has been to limit migratory movements into heavily trafficated winter areas and away from young forest plantations. In this article, we report on landscape characteristics that increase the use of feeding stations, and on how browsing activity on Scots pine Pinus sylves ...

If radio tags had no effect, apparent survival rates should not have differed between the two groups of birds. Overall, juvenile s ...
