Flying Squirrel Nests and Boreal Owls Back to: Biological Field Research Index |
|
| The photos were taken in 1995 in Idaho, where scientists were studying boreal owls. They had built nest boxes for the owls, but then found that northern flying squirrels had taken over the boxes and built nests in them, using a lichen, Bryoria sp., called black tree hair. So the researchers expanded the study to include the squirrels, their nests, and the lichens, as well as the boreal owls. |
