Data Collection

We use a variety of data collection techniques.

We capture birds in nets:

We band them using aluminum U.S. Geological Service (USGS) bands:

We collect physiological and morphological data:

Bleeding Bird
It is easy to assess fat load in a living bird. Most bird's skin is translucent, so when you blow on the feathers of their abdomen, you see something like the picture on the right below. Note that you are looking through the skin at breast muscle (red) and fat stores (tan). This bird was released unharmed. We then release them, hoping to recapture and collect additional data on them at a later date.


We have recently begun a project focused on Northern Saw-whet Owls in Lackawanna State Park.
