A band recovery connecting eastern Kansas to Grand Prairie, Alberta

Last month, Bryce caught this stunning dark bird just north of Lawrence, Kansas and discovered that it was already banded. After reporting the band and asking around, he learned that the individual had been captured and banded near Grand Prairie, Alberta in May 2015 by Sylvain Bourdages, an active raptor bander and friend of theContinue reading “A band recovery connecting eastern Kansas to Grand Prairie, Alberta”

A juvenile hybrid Red-tailed X Rough-legged Hawk captured in eastern Kansas

Luke and Bryce recently captured this amazing juvenile Rough-legged x Red-tailed Hawk hybrid in eastern Kansas. Here is our breakdown of the identification – Note the multiple Rough-legged Hawk traits such as head coloration and pattern, including pale auriculars; subtle carpal patch; buffy base coloration to breast and underwing; pale and unpatterned base to flightContinue reading “A juvenile hybrid Red-tailed X Rough-legged Hawk captured in eastern Kansas”

An attempt to better understand the Krider’s Red-tailed Hawk (B. j. kriderii)

One of the research goals of the Red-tailed Hawk Project is to better understand the “Krider’s” Red-tailed Hawk (Buteo jamaicensis kriderii). There has long been debate about the validity of this currently recognized subspecies, because of its variability and that it breeds alongside (and with) birds we consider as the subspecies borealis. The two mostContinue reading “An attempt to better understand the Krider’s Red-tailed Hawk (B. j. kriderii)”

“Liggy” the light morph harlani

Over the weekend, Neil Paprocki caught and outfitted this light morph harlani with a GPS/GSM transmitter in Northern Idaho. The members of our group decided that this harlani, the first bird to be tagged for the winter 2021/2022 field season, is to be named “Liggy” in honor of our mentor and friend Jerry Liguori. “Liggy”Continue reading ““Liggy” the light morph harlani”

Four birds join the project, in collaboration with Cedar Grove Ornithological Research Station

In October, Bryce had the privilege of visiting the Cedar Grove Ornithological Research Station (CGORS), a long-term fall migration monitoring station along the shore of Lake Michigan in central Wisconsin. Each year, strong winds from the west cause a large number of migrants to build up along the shore as they move south. CGORS isContinue reading “Four birds join the project, in collaboration with Cedar Grove Ornithological Research Station”

Dark morphs tagged in Kansas breed in sympatry with harlani

Most of our birds are back on the grid as they finish their fall migration. As a result, we have breeding locations to share – perhaps the most exciting of which are the dark putative ‘non-harlani‘ birds. Below are the breeding locations for the remainder of our tagged harlani, as well as individuals we taggedContinue reading “Dark morphs tagged in Kansas breed in sympatry with harlani”

Fall migration has started, as told by our harlani moving south!

The first three birds to check in after a summer off-grid are three of our harlani that we tagged last winter in Kansas and Nebraska. Fortunately, all three transmitters worked great and we now have nesting locations and some fine scale movement data! Here are their tracks to date: There are still a lot ofContinue reading “Fall migration has started, as told by our harlani moving south!”

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”
