Disappointment at Two Bridges

PGC's Art McMorris looks for the peregrine nest (photo by Sean Dicer)

Yesterday Dan Brauning and Art McMorris of the Pennsylvania Game Commission ventured out in PennDOT bucket trucks to band peregrine nestlings at two Pittsburgh area bridges:  Tarentum and Westinghouse.

Observers Rob Protz at Tarentum and John English at Westinghouse had pinpointed the locations on the bridges where the peregrines were nesting so Art arranged the site visits with PennDOT.

PennDOT was very helpful and the bucket trucks were impressive.  Unfortunately the news was not good.

At Tarentum, pictured above, Art McMorris leaned back to look into the nest hole but there were no nestlings, just one abandoned egg.

At Westinghouse there was one nestling too young to band and handicapped by convulsions and a deformed beak.  Not good.

This was not what anyone expected. Such a disappointment!

The adult peregrines will continue at their respective bridges, as shown below at Tarentum, but there won’t be a fledge watch at either site.

Alas.

UPDATE, Friday afternoon, May 17:  Dan and Art visited the McKees Rocks Bridge peregrine nest where they found one unhatched, abandoned egg.  Make that “Disappointment at Three Bridges.”

    Did they remove the little one with convulsions? :( So so sad and I’m so so sorry!

    No, it is still there. Penndot will check later.

    Tough news to hear :(

    This sucks. I think that the Tarentum Bridge needs a nest box. I can get you in touch with local scout leaders, maybe someone needs an Eagle project?

    Just such sad news!

    Steve-o,
    Someone actually suggested a nestbox for the Tarentum Bridge a while back on PABirds listserv. I replied that I didn’t think it would work, and Art replied in agreement. Now I’m not so sure. It might be a good idea, but I don’t know if Hope would take to it. However, it would be complicated, and would have to be coordinated with PGC and PennDot. I was thinking of something that could be attached to the side of the catwalk, myself.

    Some of the nestboxes here in the midwest are being built with the roof hinged so when opened it covers the front of the box, would something like that maybe be an option? Bob Anderson could be contacted through the Raptor Resource Project for more info on those.

    Such sad news from both nest sites.

    Such sad news. Is it just me, or does anyone else think this seems to be a very disappointing year for a lot of the “birds of prey”?

    In some respects it’s been disappointing but in others it’s been GREAT. We have 4 nestlings at the Downtown peregrine nest

    and Bald Eagles nesting in the City of Pittsburgh for the first time in centuries!

    Rob: Maybe make a box that is suspended under a catwalk? I still think that the high-rise would be a better location for a nest, but I can’t tell them that.
    I’ll be in Tarentum next month and am hoping to the falcons down at the bridge.

    I can’t help remembering poor Dorothy covering the eggs for a solid 12 hours during a snowstorm! The snow just kept piling up on the poor girl’s back, and every once in a while she’d get up and shake it off. And kept on keeping those eggs warm!

    I notice that the good outcome (downtown) is in a deep alcove on the building, and probably pretty sheltered from the elements. The more exposed nest sites (bridges, Pitt) were less successful. So I’m wondering if the winter-that-wouldn’t-die had anything to do with the low baby-count this year?

    Are there falcons on the East Rochester-Monaca bridge this year? I was down there yesterday and today but didn’t see any.

  13. Kate St. Johnon 19 May 2013 at 8:16 am

    Winter was probably not the determining factor at Pitt and some of the bridges nests. At Pitt, the unhatched eggs are part of Dorothy’s normal aging process (http://www.wqed.org/birdblog/2013/04/29/what-happened/).

    At the bridges we have 1 abandoned egg at Tarentum, 1 abandoned egg at McKees Rocks, and 1 handicapped nestling at Westinghouse. Winter is probably not the cause of these nest failures either. There are many years in which no peregrines hatch at one or more of our bridges. The sites are just not as productive as Pitt and Downtown.

    Monaca – EastRochester bridge: This year the peregrines moved their nest to the big railroad bridge downstream. The location is very high and requires railroad approval to get up there. It may be that no banding attempt will be made at this nest.

    Cool, the Beaver P&LE Bridge is my old stomping grounds too! I’ll look for flying PFs next time I go down (next week maybe.) Are they at the Monaca end, the Beaver end, or somewhere in the middle?

  15. Kate St. Johnon 19 May 2013 at 5:27 pm

    Not sure where they are on the bridge. I hear they are up very high.

    Thank you, Kate St.John, for keeping us so informed. You earned the title of “Patron Saint of Peregrines”. You are incredible.
