Early birds get the worm:
The first of two paper stemming
from the Shortest Day Survey, run in conjunction with BBC
Radio 4, has just been published online early in the Journal
of Ornithology. The study has revealed that birds with larger
eyes relative to their body size are able to initiate feeding
at dawn than birds with smaller eyes. This demonstrates
that birds are limited by their visual acuity when it comes
to finding food in the half-light of early winter mornings.
