Corrie Navis, a masters student at EMU, is using Haehnle Sanctuary for her research. 

She is investigating stress levels of American Goldfinch in urban and rural environment. She setup a feeder trap at the Sanctuary off Wooster Rd. on Sunday, 07 February to capture some birds.

The photos show Corrie with one of the birds she collected from the trap.  

The bird is captured and a blood draw is done within three minutes of capture.  The hormone cortisol is collected at that time and then 30 minutes later.  The levels of this hormone are then measured and compared. While captured, she also measures and photographs the specimen. Finally she bands the finch before release.

Research is one of the goals of the Phyllis Haehnle Sanctuary so we are pleased to provide a venue for this student to do her study.
