Bird Migration Research

[Laurie Knight <>]

There is an interesting article discussing research on the reasons why  
a number of shorebirds migrate to the Arctic region to breed.  Not  
only do they have constant daylight and a plentiful food supply, they  
also are subject to reduced predation. In some areas, the overlap with  
lemming populations are an important diversionary food supply for the  
foxes etc that would otherwise predate the birds.

summarises are more lengthy article in the same edition of Science].
