10 April 2024

Peregrine information is quiet in early April whilst the entire nests are incubating … or are they? I simply did the mathematics and Tarentum Bridge goes to hatch on or ahead of lately (see finish of article). Right here’s the scoop.

Cathedral of Studying, Univ of Pittsburgh: The day gone by I simply came about to be at the roof deck of my rental development at 6:24pm once I noticed a peregrine go off the Cathedral of Studying and head east over 5th Street the usage of territorial flappy flight. I may listen it kakking whilst a 2nd peregrine used to be within the sky over South Craig Side road circling up and up and up. The “flappy” peregrine rotated up too and dove at the intruder, using it to the east.

The day gone by’s movement detection pictures point out that the “flappy” peregrine used to be Carla. Each peregrines had been watchful all day, then all at once at 6:24pm Carla were given mad and left the nest briefly, shouting to Ecco to take over incubation. I used to be very fortunate to peer the come across within the air.

p.s. The falconcam is simply tremendous however Ozolio’s movement is funky. You’ll on occasion see an previous nonetheless shot, then spinning, then every other nonetheless shot, then sooner or later the true reside movement. The Nationwide Aviary is operating with Ozolio tech give a boost to to mend it.

Downtown Pittsburgh: On 28 March 2024 I stood close to the Monongahela Incline on Mt Washington and used my scope to see into the 3rd Street peregrine nest the place I noticed a peregrine incubating eggs.

East Liberty Presbyterian Church, Pittsburgh: On 29 March Adam Knoerzer reported that the nest is undoubtedly throughout the blue circle in his picture underneath. “The feminine is at all times there and not at the external aside from when the male pops in for a shift trade.” (I believe this at the Highland Street facet of the steeple.)

Sewickley Bridge, Ohio River: Jeff Cieslak stories: “On a number of visits all through March, one or two falcons had been fussing round beneath the bridge, close to the some distance pier. On April 3, two had been noticed in what looked to be a nest change on a beam close to that house. This would be the 3rd yr that I’ve witnessed a breeding pair in this bridge, and I’ve by no means observed a fledgling.”

No doubt now not incubating.

Each possible web page is indexed underneath …

and also you’re almost definitely questioning …

When will the eggs hatch? … How about TODAY? see underneath

The standard calculation is “34 days after incubation starts,” regardless that generally we don’t know when it began. Of the 4 nests that appear to be incubating right here’s a coarse bet.

  • Cathedral of Studying: Began round 3/19; Hatch roughly 22 April.
  • Downtown 3rd Street: Your bet is as just right as mine. We didn’t know they had been incubating till 3/28 as a result of we didn’t glance.
  • Sewickley Bridge: Noticed a nest change on 4/3; Hatch on or ahead of 7 Might … almost definitely ahead of.
  • Tarentum Bridge: Noticed incubation 3/7; Hatch on or ahead of TODAY 10 April!
