It's a Boy!

D24 is a boy!
Raptor Resource Project
9 hrs
~June 30, 2016~ GPS Tracking Transmitter Application
Raptor Resource Project (RRP) would like to announce the successful banding, transmitter application, and r...elease of the juvenile Decorah Bald Eagle known as D24.
This morning at 5:45AM CT, RRP Board Members Brett Mandernack (of Eagle Valley Nature Preserve) and David Lynch, along with Ryan Schmitz (wildlife technician from Eagle Valley Nature Preserve), and assisted by Bob Costanza (from Eagle Valley Nature Preserve) captured D24 for the purpose of applying a GPS tracking transmitter and leg band. D24 was found to be in great health, and was determined to be a male with a weight of approximately 8.5 pounds. The capture process went very smoothly and D24 was released back at the Decorah Fish Hatchery at approximately 6:50AM CT. D24 immediately took flight and perched for about an hour at the rear of the hatchery property.
Later in the morning as the breeze picked up, D24 took flight and rode the thermals around the Decorah Fish Hatchery. He was eventually joined by his sibling D25 and the two juveniles soared together. After approximately and hour the two juvenile eagles returned to perch: D24 on the original Decorah Eagles nest tree (N1) and D25 on top of the bluffs that surround the hatchery, a common perching place for these juveniles and the adults. Watching the juvenile eagles learning to master flight and landings was quite a sight to see!
Interesting Facts:
-D24 was captured using a Ring Padam Noose trap, which has been used by Eastern falconers for centuries as it is elegantly simple, lightweight, and very safe for the bird.
-The capture and transmitter application, which took days of preparation and planning, was completed in less than 2 hours.
-Like his predecessors, D1, D14, and Four, D24 will join the eagle migration and travel study that began at Eagle Valley Nature Preserve in 1999.
-RRP will now begin to monitor D24 on a daily basis to watch his travels will share tracking information with the public both on Facebook and on our project website at http://www.raptorresource.org/
After tracking primarily adult eagles for 15 years to determine migration dynamics in the Upper Midwest, their fidelity to migration routes, as well as fidelity to and mobility on summer and winter ranges, The Eagle Valley Nature Preserve study has recently been focusing on immature eagle travels and observing if/how the migration behavior changes as the birds mature. As with any species, how can we be effective stewards if we do not understand basic travel behavior? The Raptor Resource Project is working hard to live our mission: “ to preserve and strengthen raptor populations, expand participation in raptor preservation, and help foster the next generation of preservationists”. RRP would like to extend special thanks to Brett Mandernack for his support and dedication to raptor preservation.
We would like to thank all of the RRP fans for their support and we look forward to learning more about the travels of D24 along with you!
