Peregrine information is quiet in early April whereas all of the nests are incubating … or are they? I simply did the mathematics and Tarentum Bridge goes to hatch on or earlier than as we speak (see finish of article). Right here’s the information.
Cathedral of Studying, Univ of Pittsburgh: Yesterday I simply occurred to be on the roof deck of my house constructing at 6:24pm once I noticed a peregrine go off the Cathedral of Studying and head east over Fifth Avenue utilizing territorial flappy flight. I might hear it kakking whereas a second peregrine was within the sky over South Craig Avenue circling up and up and up. The “flappy” peregrine circled up too and dove on the intruder, driving it to the east.
Yesterday’s movement detection pictures point out that the “flappy” peregrine was Carla. Each peregrines had been watchful all day, then immediately at 6:24pm Carla bought mad and left the nest rapidly, shouting to Ecco to take over incubation. I used to be very fortunate to see the encounter within the air.
p.s. The falconcam is simply high quality however Ozolio’s stream is funky. You’ll typically see an outdated nonetheless shot, then spinning, then one other nonetheless shot, then ultimately the precise stay stream. The Nationwide Aviary is working with Ozolio tech help to repair it.
Downtown Pittsburgh: On 28 March 2024 I stood close to the Monongahela Incline on Mt Washington and used my scope to look into the Third Avenue 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 certainly throughout the blue circle in his picture beneath. “The feminine is all the time there and by no means on the outside besides when the male pops in for a shift change.” (I believe this on the Highland Avenue facet of the steeple.)
Eckert Avenue, Ohio River: As of 5 April Jeff Cieslak experiences {that a} peregrine pair is close to the Eckert Avenue nest website however they don’t look like nesting there. He says it’s the identical feminine, most likely a brand new male.
Sewickley Bridge, Ohio River: Jeff Cieslak experiences: “On a number of visits throughout March, one or two falcons had been fussing round beneath the bridge, close to the far pier. On April 3, two had been noticed in what seemed to be a nest trade on a beam close to that space. This would be the third yr that I’ve witnessed a breeding pair on this bridge, and I’ve by no means seen a fledgling.”
Monaca Railroad Bridge, Ohio River: For some time it regarded as if the peregrines would nest however their try will need to have failed. eBird experiences from the “Mouth of the Beaver River” hotspot in late March by way of 2 April point out that each peregrines are seen concurrently. Positively not incubating.
Rt 40 Bridge, West Brownsville: Fred Kachmariak and Jeff Cieslak each visited this bridge in mid to late March and noticed a solo peregrine. Right here’s Jeff’s picture from 23 March. Since this website was profitable previously, it appears to be like promising for a household this yr.
Each potential website is listed beneath …
and also you’re most likely questioning …
When will the eggs hatch? … How about TODAY? see beneath
The same old calculation is “34 days after incubation begins,” although usually we don’t know when it began. Of the 4 nests that appear to be incubating right here’s a tough guess.
- Cathedral of Studying: Began round 3/19; Hatch roughly 22 April.
- Downtown Third Avenue: Your guess is pretty much as good as mine. We didn’t know they had been incubating till 3/28 as a result of we didn’t look.
- Sewickley Bridge: Noticed a nest trade on 4/3; Hatch on or earlier than 7 Might … most likely earlier than.
- Tarentum Bridge: Noticed incubation 3/7; Hatch on or earlier than TODAY 10 April!
