Mom and Dad at N2B

Mom and Dad are busy working on N2B – with a side-trip to N1! As the solstice approaches, look for bursts of activity from Mom and Dad, especially on warm days, and continued eagle ‘flirting’ – pecking, brushing against one another, and tail touching. Although productive mating is very brief, eagles have been observed copulating ten months of the year and its something we are watching for at N2B. We are supposed to have a stretch of warm weather between

What a year!

What a year it has been! Our banding season stretched from late May to early July this year, although a combination of black flies, hippoboscids, extreme weather, and reduced productivity caused our numbers to fall. In 2017, we banded 58 falcons at 22 sites as compared to 77 falcons at 25 sites in 2016. We also replaced cameras and microphones at many of our nests, started a new partnership with Explore to provide an ads-free stream of the Decorah Eagles,

Eagle Eyes!

Human Eye versus Eagle Eye

Has anyone ever called you eagle-eyed? Relative to humans, bald eagles have larger, sharper eyes that see further, collect more details, and produce stereoscopic vision to greatly improve depth perception. A bald eagle’s visual acuity begins with its eye size and shape. Dad’s somewhat tubular eyes occupy over 50% of the volume of his skull, as compared with less than 5% in us spherically-eyed human types.  He can voluntarily adjust the curvature of his large cornea and lens (we’re restricted

Videos: pole-vaulting sticks, nuzzling, net visitors!

In Decorah, Mom brings in a pole-vaulting stick. Although eggs are still about three months away, Mom and Dad work on the nest bowl together and do a little nuzzling under IR candlelight. Meanwhile, Mr. North eats with his mouth open (check out the size of that bite!) and a bluejay, pesky squirrels, and an intrepid crow all visit the nest – and the Norths! I really enjoyed all of these videos, but especially liked Mom and Dad Decorah under

A Veterans Day Thank You from the Raptor Resource Project

A Veterans Day thank you from all of us at the Raptor Resource Project! November 11, Veterans Day, honors and celebrates the service of all military veterans. Thank you to our veterans for their patriotism, love of country, and willingness to serve and sacrifice for the common good. You heard the call of duty and left the lives you knew to answer it. When we think of veterans, we usually think of the people we know. But our veterans also

Cam on date: October 7th!

It has been a busy couple of weeks for us in Decorah! We started camera work at 9:00am on September 13th and finished up at roughly 7:00pm on the evening of September 22nd. The crew had moments of joy, a little hand-wringing, and no small amount of sweating in the unusual 90+ degree heat that prevailed almost the entire time we were there. We saw Mom and Dad Decorah sitting in a maple tree, fishing in the pond, and perched

Live from the Fort St. Vrain Bald Eagle nest!

Back in late August, John and I traveled to Platteville, Colorado, to work with Xcel Energy employees Bill Heston, Tina Lopez, and Naresh Dahagama on an upgrade to the Fort St. Vrain Eagle cam. Over three days, we took down and re-positioned the existing cam, added a new PTZ cam, cleaned up the solar panel area, added two radios and a couple of networked video recorders so plant staff could watch their eagles from the lunchroom again, threw in a

What’s on the Menu at Fort St. Vrain?

So what’s on the menu at Fort St. Vrain? While we were up in the nest, I decided to collect prey remains. We don’t have the necessary permits to take feathers (of which I found only two, both belonging to prey), but there were plenty of skulls and a few turtle shells. I got them home, laid them out on a table, and started ID’ing them. Some Moms bring home t-shirts and postcards. I bring home skulls and photos of

Raptor Banding and Trapping Station

The Raptor Resource Project and Luther College have launched a trapping station project to collect data on birds of prey, provide field-based research opportunities, and deliver environmental education to youth. The project was funded via a Resource Enhancement and Protection/Conservation Education Program (REAP/CEP) through Iowa’s Department of Natural Resources. To learn more about REAP/CEP, including some of the really cool projects they have funded over the years, follow this link: While we know a fair amount about cameras and
