Pick a Bird Brain Series Jan. 24, 2023
At Hawk Ridge an average of more than 60,000 raptors are counted migrating through Duluth each fall, and over 2500 are banded. Some of these banded birds are recaptured at points further south but very few are recaptured or traced to their breeding grounds generally north of Duluth. As a result, very little is known about the distances they travel from their breeding grounds and the timing of their passage through Duluth during migration. Do birds from further north come through earlier than other birds of the same species breeding further south?
In this Pick a Bird Brain Program, Emily Pavlovic will discuss the research she completed for her master’s degree at UMD using a combination of stable isotope analysis and banding return data to learn more about where Northern Saw-whet Owls, Sharp-shinned Hawks and Red-tailed Hawks are breeding, and whether the location of their birth impacts when they are likely to pass through Duluth on their way south.
