Not for sure, but Decorah Mom is on the nest late tonight and she has that "trance-like" look.
Maybe an egg coming?

I'm surprised the egg would be left uncovered for any length of time with the temps in the low 30's.

But, I'm sure they know what they're doing.

Years ago, during a polar vortex, there was concern from even the director that the eggs were uncovered for too long.

That was much colder than this winter event and maybe a bit longer with eggs uncovered.

All three eggs hatched and the eaglets all fledged. I think that event was in 2014. It was a stressful event, but a great lesson in, "Trust Nature, Trust the Eagles."

Before I close for the night, a flashback to 2012. Mom may repeat this in the morning.. 2-20-12 so about this same time seven years ago. Mom may be blanketed in the morning with the blizzard warning tonight in North Iowa.

And to close the night Mom lays her second egg. The video is about 22 minutes, but it is pretty amazing. A bit after three days after her first egg with her new mate. Friday or Saturday may be the third egg if it happens.

And as of 7:05 Mom Decorah lays her third egg. Only 4% of eagle couples lay three eggs. Mom Decorah has done it consistently since 2009. She laid two in 2008.

Mom has laid 34 eggs. 31 of them hatched and were raised to fledge.

Another thrill today was a past eaglet, that was mounted with a transmitter, was spotted today.
She has traveled thousands of miles and was spotted today.

Default Unusual nest companions

I am not sure what to make of this group dynamic.

Mom is sitting on three new eggs. The mice live in the bottom of the nest and normally do not surface during the nesting season. In the off season the mice have free reign to clean up the nest.

Unlikely nest companions

Just a sidenote, this video was shot with the night vision camera so neither party can see each other well, but they probably realize each other are there. Some complain that a light is shining on the nest and that it is disruptive. (It is IR light that neither eagle nor human can see)

A school teacher was watching this and one of her 4th grade students noted the size of Mom's pupils. "Teacher, look at the size of Mom's pupils. It must be really dark there in the nest."

^^^^ The eagles and the mice have a relationship called "Facultative mutualism, A type of mutualism in which the interacting species derive benefit from each other but not being fully dependent that each cannot survive without the symbiotic partner." Basically we tolerate each other and provide a service for each other, but we do not need each other to survive.

Well one of the mice violated the terms of the agreement and pestered Mom on the nest a dozen times while she is sitting on three new eggs. She wing wacked him a dozen times before she tired of nuisance. Usually a mouse is not worth the effort or energy of an eagle, but...


And this view of Mom explaining the term "Apex Predator" to the mouse that ignored a dozen warnings..Mouse in the beak.




Unrelated to the event with Mom and the pesky mouse, the event did provide a photo shot of Mom's brood patch. It is a bare spot on the male and female eagle parents that they have during incubation. It is rare to get a photo of the eagles belly, but Mom offered it up while dealing with the mouse.

The brood patch is bare skin to transfer heat to the eggs. It grows back when the eaglets hatch and get their feathers and can therm-regulate on their own.

Yeah, his mouse buddies bragged at how much they could get away with on the eagle's nest. Sometimes right next to a sleeping eagle.

He may have missed the part where his buddies said, "But NEVER try that in the daylight, though! The eagles do not have great night vision, but in daylight they have laser vision and they are pretty dang quick." Ooops..

No doubt. I can’t believe he came back after the swat in the video.
If there were 12 before that, well that’s just a mouse version of a Darwin Award.

Pretty sad morning in Decorah. I had turned on the site at about 6am. At about 7am Mom clocked out of her night shift and there was a broken egg that came out of the egg cup with her. Mom has a long history of three eggs hatching and fledging. This year may be only two. (which is the majority of eagle nests. Decorah was always in the top 4% with three eggs)

Raptor Resource Project on the broken egg at Decorah

Mom and DM2, the new mate this year, did not spend any time mourning a broken egg. They have two more eggs that need their constant attention.

And life goes on..
