3/1/18: Check out the GVSU webcam

The peregrines that claim the nest box on GVSU’s Eberhard Center have been visiting the nest box several times a day.  Most of the time it appears to be the same male as last year.  He enters the box, checks out the bottom of the box, possibly rearranging the gravel to create a depression for the eggs.  Sometimes he perches on the front rail for a time before leaving.  Occasionally he is joined by the female in the box.  I haven’t gotten a complete look at her bands, but it sure looks like Majestic.

GVSU webcam can be found here.

My best guess is that they won’t lay eggs until the last week of March or early April, which is typical for the peregrines in this area.  If the weather stays warmer than usual, however, they could lay earlier.  As egg laying time gets closer, we might catch the pair mating on the front rail, but in my experience, most mating is done away from the nest box.

As always, please let me know when and where you see the falcons.  Observations of mating are of special interest right now.  By the way, I haven’t gotten many reports of falcons in or around the courthouse box.  It would be great to confirm that a pair is also using that box.

In response to an earlier question, yes, the nest box now has an access for safely banding the chicks.



  1. Saw one peregrine in flight Monday 2/26 in flight over Monroe and Sixth St.

  2. I have seen the leg bands and they indeed are b/blu, 29/M. Still trying to figure out the male.

    • Thanks for the confirmation of the female’s band number. The male’s top black band is a sideways R or a B. Since his lower band is unreadable, we’ll likely never know exactly where he’s from.

      • One of Majestic’s parents fledged in Muskegon in 2013. Hopefully there’s enough genetic variety.

      • I don’t think in-breeding will be an issue. All of the falcons banded in Midwest are recorded in the Midwest Peregrine Society’s database. My search of the database shows a few falcons with an R or a B on the top band, but none are from Michigan, and the most recent record is for a bird fledged in 2005. Wild peregrines can live to be 20 years old, but the average is much less. My guess is that our male is from outside the Midwest, and I haven’t found a band database to search for those falcons.

      • I searched the database using an asterisk, denoting sideways, and the *R brings several results of males banded in Indiana in 2014. *B bring up older bandings, or some females in Milwaukee. If I were a betting man, I’d go with a male from Indiana born and banded in 2014.

      • Now I’m even more disappointed that we can’t seem to read the bottom band below the *R! I agree that an Indiana born male makes the most sense, but we’ll probably never know which one.

  3. 12:20 PM Friday March 2 (today), over Ionia Ave at about Trowbridge St: several of us got a real nice look at a peregrine chasing off a red tailed hawk.

    • Cool! Any idea what perches they are hunting from?

  4. Saw a pair of peregrines soaring over Trowbridge at Monroe 3/13/18 a few minutes ago, at about 1:50 PM. Moving southerly toward downtown.
