Colorful sunrise at DNN. Red to pink to orange to gold. Cam ops gave us a nice panning tour of the creek area. Extreme closeup pic of the brush pile.  Good views of the tall long grasses along the banks (no pic), and DNF brought some to the nest about 11 AM.  MrN brought her a nice long stick.

Jaspurr, thanks for the heads-up to listen for the owl on the rewind.

Several BEs around the creek this morning. One is a sub-adult, can't tell about the other, could be one of the Norths.

Jaspurr, you are soooo right about the beautiful North nest!  The location is perfect for many different angles of wonderful views by the expert camera operators.  Thank you all. And to the RRP folks who put those cameras in the perfect places.

I agree about the beauty of this nest and its location.  The new camera angles are terrific - thanks cam-ops! It doesn't hurt that there's a beautiful eagle pair living here! ;D

The Norths spent the night in the Love tree. Just at color-on, DNF did some stretching and calling. She made a short nest visit, too.

From RRP's FB page about DNN:

Raptor Resource Project

At Decorah North, DNF and Mr. North stay busy with nestorations (the 2022 penthouse project is looking good!), visitors, and copulation. While we admire an eagle and a crow on the Flyway, a subadult eagle appears to admire itself in the water!

November 22, 2021: Squirrel looking for a snack - https://youtu.be/kbt3V4-EjVU. Better watch out, squirrel! When the eagles are away, the squirrels do play!

November 21, 2021: Copulation #3 on cam - https://youtu.be/pSogfYWRqkI. It's interesting to me that the North eagles copulate this time of the year. We know that a lot of migratory birds shrink their gonads once they are done with their reproductive cycle. Sex hormones stop flowing and don't start again until some time after the winter solstice, when gonadal growth is triggered by increasing daylight length, especially in birds that winter north of the equator. But mated territorial eagles have been observed copulating ten months out of the year and we see reproductive activity at the North nest while the days are getting shorter! Do non-migratory eagles have intact gonads year round? Are there other circannual clocks that could come into play? Sex hormones and increasing daylight length still remain a key driver of reproductive activity in the eagles we watch, but I have to think they aren't the only factor.

November 21, 2021: DNF works on wonky stick placement - https://youtu.be/MujjHld6Mew. Wonky sticks tie the nest together, but they aren't always very easy to place. Fortunately, DNF is a pro! She deftly weaves her latest stick into place. The North 2022 penthouse project is looking good!

November 19, 2021: Visitors - https://youtu.be/d0XOr6f3Hhs. Two adults, one juvenile, and one subadult pay a visit to the Valley of the Norths!

Beautiful sunrise pics today. MrN and DNF have been on the nest early this morning. Rewind to find them on the Ladder branches, close up, Each did a big rouse and some preening before flying away.

Couple more pics from this morning.  I'm in awe at DNFs skill in weaving in those long sticks.
