More birds added to our project thanks to the Mackinac Straits Raptor Watch

Bryce recently spent a week at the Mackinac Straits Raptor Watch in Mackinaw City, Michigan, where he and Nick Alioto deployed eleven units on migrant Red-tailed Hawks. Nick will be conducting a movement ecology study focused on migrants in the great lakes region, and we’re excited to see what insights he gains from these taggedContinue reading “More birds added to our project thanks to the Mackinac Straits Raptor Watch”

More birds join the project in the eastern Great Plains

We’ve been busy! Over the past two weeks, we’ve been putting transmitters out on the eastern Great Plains, primarily in Kansas. We added 8 new transmitters and an additional 8 birds that are marked with color bands. Take a look at the new birds! Apart from the generous contributions from the Kansas Ornithological Society andContinue reading “More birds join the project in the eastern Great Plains”

Meet Ahsoka – a light-morph harlani carrying a transmitter in Kansas

Meet Ahsoka, an after fourth-cycle harlani that wears the color band blue – 3Z! Luke added this excellent light harlani to our growing group of birds carrying transmitters. We first found this individual last year on its wintering territory just outside of Lawrence, Kansas. We checked regularly during our trapping efforts last winter to seeContinue reading “Meet Ahsoka – a light-morph harlani carrying a transmitter in Kansas”

Meet Obi-Wan – a new bird carrying a transmitter in Vermont

Meet Obi-Wan, an after second-cycle that wears the color band blue OB. Over the weekend we were able to trap and transmitter this bird in collaboration with the Vermont Institute of Natural Science. We also caught and color banded a few other birds. If you live in the New England or eastern Canada, keep anContinue reading “Meet Obi-Wan – a new bird carrying a transmitter in Vermont”

Meet our two new birds – a harlani from Utah, and an abieticola from Vermont

Grogu Grogu is a fourth-cycle dark morph harlani captured in Salt Lake City, Utah on 18 December 2020. The primary molt limits on this individual indicate an after third-cycle, but we actually know the age of Grogu because the bird was caught and banded at the Salt Lake International airport in 2018, when it wasContinue reading “Meet our two new birds – a harlani from Utah, and an abieticola from Vermont”

Blue 1W is our First color banded bird of the project – A gorgeous juvenile Krider’s in eastern Kansas!

Yesterday, 10 November 2020, Luke caught this stunning juvenile near Lawrence, Kansas (nice work Luke!). Unfortunately, we are not putting out telemetry units on juveniles, but Luke still took the necessary samples, and put a color band on the bird. This bird is now carrying a blue 1W on its left leg, so keep anContinue reading “Blue 1W is our First color banded bird of the project – A gorgeous juvenile Krider’s in eastern Kansas!”

We have breeding locations!

After months of waiting, our birds Kansas 01 and 02 have started their fall migration back to their wintering areas in Kansas. We now know where each bird breeds, and we can tell a bit about each just from this knowledge. Surprisingly, both birds breed in an area of northern British Columbia, in a glacialContinue reading “We have breeding locations!”

Are there B. j. calurus that winter in the great plains?

The question of whether or not Western Red-tailed Hawks winter on the great plains has been debated for years. Below I detail an anecdote that shows that at least one bird does… We were surprised to catch the bird below in eastern Kansas last winter. It’s a rufous bird that as far as I canContinue reading “Are there B. j. calurus that winter in the great plains?”

A Potential Intergrade harlani X abieticola

In February 2020, we trapped a very interesting dark bird north of Atchison, Kansas. We were targeting dark non-harlani for our transmitter effort to track these birds to their breeding grounds as a first step for understanding if the subspecies abieticola is polymorphic. At first pass this bird looked like our target, but when weContinue reading “A Potential Intergrade harlani X abieticola”
