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

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

Persistence Pays Off – a post by Brett Mandernack about the fitting of D27’s transmitter.

D27's transmitter fitting

It is early August and I have one satellite transmitter (or PTT) yet to deploy on a young eagle. Dave and Ann Lynch spent two solid weeks in late June/early July perfecting their craft of artful presentation of fish to the Decorah fledglings, yet the “kids” instead chose to food-beg loud and often and insist Mom or Dad bring them food at the nest. There was no evidence of any of the fledglings ever picking up a fish during that

Announcing – the final fledge!

D27 fledges!

Last night we announced that D27 hadn’t fledged yet. And it hadn’t – at least, not at 1:15pm. But I missed D27’s flight from the nest at 2:16pm. It wasn’t an especially long flight given that D27 returned fairly quickly, and we didn’t have boots on the ground to verify that no one was in the nest…at least, not at 2:16pm! However, after a great deal of discussion with moderators and a thorough review of footage from the time period,

Eaglet Growth and Development, Week Two

D26 asleep on the nest

It is April 10 as I write this, and our eaglets are growing rapidly! In Decorah, D26 is 10 days old, D27 is 9 days old and D28 is 6 days old. At Decorah North, DN4 and DN5 are 12 and 11 days old. And at Fort St. Vrain, FSV34 and FSV35 are 15 and 13 days old. D26. See the earhole? In their second week of development, the eaglets will gain roughly two pounds between their 7th and 14th day

Welcome, D28!

Welcome to the world, D28! D28 hatched at 6:57AM nest time (central) this morning, completing hatch at the three bald eagle nests we are watching this year. We have two at Xcel Energy’s Fort St. Vrain nest, three at Decorah, and three at Decorah North! It’s hard to catch a glimpse of the eaglets with the Seattle-style rain Decorah is getting this week, but this video from Blossem Holland gives us a nice look at the new hatchling and a

Hip pip hooray!

External pip in Decorah

We have an external pip in Decorah! Thanks to Prairiefirewind and the Decorah mods for their hard work getting this very brief moment. D26 is on the way! Video: https://youtu.be/BN5Var9p8ys It has been 37 days, 21 hours, and 36 minutes since Mom laid egg number one in Decorah this year.

Nest Round-Up!

DN4

We have a nest round-up! We are getting a lot of questions about the Decorah nest. Have we seen pip? What is going on there? Are you still reporting on it? We are! As of 8:35pm on March 29: Decorah: We haven’t seen a verifiable pip yet, although the rain has Mombrella and PopTent up and in action! We are at 37 days + about an hour and a half now, so our best guess for an external pip is
