  1. What chickadees can tell us about climate Ross Caruso Meteo 482 4/22/14 Article posted on March 19, 2014

  2. 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

  3. Black-capped vs. Carolina Chickadee

  4. 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 Chickadee Population of POI’s in 1998 (Hawk Mountain-blackcaps) (Nolde Forest-mixed) (Chester County-Carolinas)

  5. 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
