Will HM’s eggs hatch?

March 14, 2023: HM shortly before leaving the nest.

On Tuesday March 14th, two brush pile burns were conducted south of the Decorah Eagles nest near the hatchery. During the early morning, the wind was blowing to the south, which carried smoke away from the nest. But at about 10:00 AM, the wind switched direction and began carrying smoke north toward the nest. Wind speed also increased from about 2.2 to about 9.2 miles per hour, which blew even more smoke and some light ash as the day progressed.

Nest-guarding and intraspecific intrusions

March 16, 2023: Mr. North and his last evening of incubation.

The Decorah North Eagles have been dealing with a lot of intraspecific intrusions this year. Intrusions happen when members of other species encroach on or enter a nest in search of food, nesting materials, or a nest: think squirrels, mice, raccoons, chickadees, woodpeckers, red-tailed hawks, house sparrows, and other animals we’ve seen in and around our nests. Intraspecific intrusions happen when other eagles intrude on daily nest activities in search of food, new mates, or breeding territories. They can lead

What’s Going on at the North Nest?

February 24, 2023: DNF and Mr. North back on the North nest.

North nest watchers know that 2023 is off to a very unusual start. DNF has laid her first egg on February 16th for two years in a row and her average first lay date, excluding her first year, is February 17. We were surprised when she didn’t lay her first egg until February 20th, especially after her extended stay in the nest on the night of February 14. Male and female eagles both incubate eggs, but female eagles almost always

February 7, 2023: What happened to HD’s foot?

February 7, 2023: HD's foot.

What happened to HD’s foot? On February 3, several sharp-eyed volunteers and fans noticed that one of his toes appeared to be injured. We talked with Dr. Laura Johnson and Master Bander Dave Kester about the injury. What’s going on? It isn’t easy to diagnose a condition based on photos, but Laura told us that it looks like an injury (possibly a constriction or bite) caused a loss of blood supply to HD’s toe and nailbed. We first noticed the

Nest N3 destroyed in the strong storms that rolled across NE Iowa on Saturday night

July 28, 2022: The view from the trail behind Walmart. N3 is gone. Many of the dead trees (and some of the live ones) either fell or took damage from the wind and other trees.

Nest N3 – the nest that Mom and DM2 built behind the Walmart in the fall of 2020 – was destroyed when the nest tree fell in the strong storms that rolled across NE Iowa on Saturday night. Based on the debris line and flattened, muddy grass along the upper Iowa behind Walmart, the river was at one point roughly four feet over its current flow level. The discharge in cubic feet per second more than tripled overnight following 4+

June 14, 2022: Fall at Great Spirit Bluff

June 14, 2022: Falcon falls from Great Spirit Bluff

The falcons at Great Spirit Bluff have jumped out of the box. We originally thought that we were seeing some exploratory behavior, but it looks like the blackflies drove the youngest falcon out before the older two. We’ve been asked if we plan to go down and rescue them. For now, we’re leaving them alone. It is our experience that falcon parents will take care of their young by flying into the understory to find, feed, and defend them. We

Decorah Eagles Update at N3 with Mom Decorah & DM2

Our new male and female close up and personal! Notice the differences in the two? Male front, female back.

– By RRP Director John Howe We have finally completed our recent assessment of what we believe is going on at N3 and what Mom Decorah and DM2 are up to. ALL the eagles of Decorah are out doing the things that, well…eagles do. We don’t always understand why they are doing what they do, but they really are not obligated to report back to us humans either! First, we can report that Mom Decorah and DM2 appear to be

As The Nest Turns: Decorah

April 11, 2022: The new eagles. He's left, she's right, and they look a lot like Mom and DM2. I can see some subtle differences up close and we're working on iris fleck and feather catalogs.

If you’ve been watching the Decorah Eaglecam, you know that a new eagle pair appears to be settling into the starter nest we built at N1. I’ll be honest: a lot of us have mixed feelings about that! We hoped the nest would lure Mom and DM2 back to the hatchery, but they chose to nest in N3 again this spring. Still, their behavior this fall gave us a little bit hope that they might make a different decision in

‘House Hunters’ or ‘As The Nest Turns’? The latest from Decorah…

April 1, 2022: The cast of characters!

‘House Hunters’ or ‘As The Nest Turns’? Why not both! If you’ve been watching the Decorah Eagles, you know a Canada Goose is incubating six eggs in N2B and we’ve seen a pair of eagles in and around N1 for a couple of weeks. We initially identified them as Mom and DM2, although we wondered why they were so far from their nest after full incubation began. But the couple at N1 last night were clearly not Mom and DM2!

Finally, an egg at N3!

What has been going on with Mom and DM2 this year? RRP staff and volunteers have been monitoring Mom and DM2 at N3 and the hatchery, and we have a pretty good record of their whereabouts with boots-on-the-ground observations and appearances on the hatchery cams. We have documented her standing in the nest for long periods of time, but she didn’t begin incubating until sometime between Robin’s observations on Sunday, March 20 and Dave Kester’s observations on the morning of
