How it started Villanova University
biology professor Robert Curry
Looked for an interesting project for his students
He found it in his own backyard feeder: The Chickadee
Wanted to catch a lot of birds and monitor them
Nesting's, offspring, partners, etc.
Focused on two species: Carolina Chickadee and the Black-Capped Chickadee
Black-capped vs. Carolina Chickadee
Location of project• Good candidates for his
project, since they don’t migrate seasonally
• The areas in which they intersected contained hybrids
• Made fake nests in those areas (450 total)
• Started collecting blood samples from birds to determine bird type
• Started project in 1998(Hawk Mountain-blackcaps) (Nolde Forest-mixed) (Chester County-Carolinas)
Chickadee Population of POI’s in 1998
Surprising Results Noticed more hybrids in
Hawk Mountain Found that the line
separating species was about 17 degrees
Carolinas wont live where its colder, while black-caps will
Warmer temperatures and Carolina Chickadees were moving north in sync at an average of .7 miles a year
Other possible organisms, parasites, and diseases could be following the same path
