Telemetry is a valuable tool for understanding species behavior like movement patterns, dispersal distances, and survival rates to name a few. Fitting wildlife with telemetry units requires years of experience to ensure the capture and transmitter attachment do not stress or harm the animal or their young. CCB staff have over 25 years of transmittering experience with raptors, shorebirds, songbirds, and wading birds. These skills are learned by hands-on mentoring from one biologist to the next, passing on knowledge and techniques. CCB staff have trained or consulted with many other researchers around the globe ensuring safe transmitter attachment practices are being used on imperiled avian species. Below are some ongoing raptor projects in which we have recently provided technical assistance on harnessing techniques.
Golden Eagles (Aquila chrysaetos) in Finland
Olli-Pekka Karlin, lead researcher
Objectives: Track four golden eagles 1) to help reindeer herders find mammalian killed reindeer and 2) to understand golden eagle movements around Finnish wind farms.

Wedge-tailed Eagles (Aquila audax) in Australia
Simon Cherriman, lead researcher
Objectives: Tracking wedge-tailed eagles 1) to understand foraging behavior of breeding adults 2) dispersal movements of juveniles and 3) survival of juvenile eagles.

Crowned Solitary Eagle (Harpyhaliaetus coronatus) in Argentina
José Hernán Sarasola, lead researcher at Centro para el Estudio y Conservación de las Aves Rapaces en Argentina-Universidad Nacional de La Pampa (CECARA)
Objectives: Track juvenile crowned eagles to understand 1) movement patterns, 2) causes of mortality, 3) age to first reproduction, and 4) dispersal distances.

A bald eagle nest just off the Poropotank River in Virginia in 2003. A nest with two equal young and ample food was a normal scene during this time period. This reflects a golden period during the late 1990s and early 2000s when males had more leisure time to hunt and provide for broods. Photo by Catherine Markham.
Breeding female on the Eltham Bridge. This female was hatched on Elkins Marsh along the seaside of the Delmarva in 2010 and has held the territory on the Eltham Bridge since 2013 with three successive males. She has been very aggressive and protective of the nest site and has held the territory together. She was found with a wing injury from a collision in December and could not be rehabilitated. She is one of a number of falcons that have been documented to go down in 2022. Photo by Bryan Watts.
