The Neighborhood Watch: Alarm Calls

January 8, 2023: HM responds to the neighborhood crow watch with a warning of his own.

On Saturday of January 7, we watched HM and HD respond to alarm calls issued by the local neighborhood crow watch. Alarm calls convey information with pitch, volume, bandwidth, repetition, duration, inflection, and sound. Most of us are familiar with a chickadee’s ‘chick-a-dee-dee-dee’ alarm call: a social signal that tells other chickadees to rally in the vicinity of the predator – usually a perched bird of prey – and join in a chorus or mob of calling. The number of

Tick-tock egg clock! Date guesstimates all around our nests.

January 5, 2023: HM near N1

Tick-tock egg clock! Okay, it’s a little early to start counting the minutes, but here are the days we’ve penciled into our planners for first eggs, first falcons, and ice-out on the Mississippi River Flyway. Get your (RRP) calendars out and feel welcome to make your own best guesstimates. Eggs will be here before we know it! Decorah North I’m saving the afternoon of February 16th for DNF’s first egg! She’s been a remarkably consistent layer date and timewise, although

January 4, 2023: HM and HD in snow.

Is anyone else tired of what seems like the eleventy-billionth winter storm this season? Decorah and Decorah North were hit with snow, rain, and sleet today: a dreaded mix that can be tough on wildlife adapted to January’s usual snow and subzero temperatures. Despite the frightful weather, HD and HM stayed busy with nestorations, a shared lunch, and some preening. The days are already five minutes longer than they were on the solstice and we’ve seen behavior that indicates both

Who is that eagle with a transmitter?

D27? This was the only look we got at the eagle's face. D27 turned five years old in April.

Our sharp-eyed camera operators found an eagle with a transmitter on near N1 this morning! While we couldn’t get a band or transmitter number, Brett thinks this was most likely D27 based on the eagle’s location and age. We haven’t heard from D27’s transmitter since late November, but we know that she was in Decorah and tends to spend time in an area between the hatchery and Highway 52. She is looking great and we’ll keep searching for potential nests

News and Nestflix from Decorah!

December 20, 2022: HD and HM visited N1 at 2am. We're not sure what prompted their late night visit, but it might have been an owl strike.

Grab a warm drink, hunker down, and enjoy HD and HM’s snowy NestFlix nestorations in Decorah! Several of you have expressed concern about Mr. North and DNF. It’s not uncommon for eagles to disappear during extremely cold weather, since they seek shelter and reduce activity to maximize energy gain and minimize energy loss. We saw the Norths last Wednesday (thanks, Pauline) and we’re looking for them again now that things have warmed up. If we don’t see them on camera

Can birds detect severe weather? Storms, cold, and Bald Eagles in winter!

January 2, 2022: Mr. North looks stylish in his wintery down jacket! Subzero temperatures had every one in winter gear today.

Can birds detect severe weather? I’m watching the birds at my feeder as a major snowstorm rolls in. American Golden Finches, Dark-Eyed Juncos, Black-Capped Chickadees, and White-Breasted Nuthatches are decimating my seed feeder, while our resident Downy, Hairy, Red-Bellied, and Pileated Woodpeckers clean out my suet feeder. The feeder action started yesterday. Did our birds know a major storm was on the way? While birds can’t predict long-range weather patterns, they have at least two ways to detect and prepare

2022 Memory Lane Moments: Nestorations at N1

Besties or Beakersons? HD and HM place the furniture at N1.

We asked our volunteers to give us their favorite moments from 2022. While we miss Mom and DM2, Glogdog is so happy to see nestorations at N1 again! We’re curious about what 2023 holds in store and crossing our talons for eggs and eaglets at Decorah North and in Decorah. To see the full video, follow this link: https://youtu.be/anJ4Q0AAYdY.

Birds and Nest-Building

A blackbird's cup nest

When I say ‘bird’s nest’, you know the type of nest I’m talking about, right? It could be a bald eagle’s stick platform high up in the branches of a tree. Or perhaps a peregrine falcon’s scrape in dirt, sand, or gravel on a shallow cliff ledge. Or maybe the burrows that bank swallows and belted kingfishers excavate in dirt, the cavity nests that woodpeckers excavate in dead wood, or the woven nests that orioles and weavers build. When I
