10 April 2024
Peregrine information is quiet in early April whereas all of the nests are incubating … or are they? I simply did the maths and Tarentum Bridge goes to hatch on or earlier than immediately (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 condominium constructing at 6:24pm after I noticed a peregrine go off the Cathedral of Studying and head east over Fifth Avenue utilizing territorial flappy flight. I may hear it kakking whereas a second peregrine was within the sky over South Craig Road 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 images point out that the “flappy” peregrine was Carla. Each peregrines had been watchful all day, then instantly at 6:24pm Carla received mad and left the nest shortly, 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 You’ll typically see an outdated nonetheless shot, then spinning, then one other nonetheless shot, then finally the precise dwell stream. The Nationwide Aviary is working with Ozolio tech assist to repair 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 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 inside the blue circle in his photograph under. “The feminine is at all times there and by no means on the outside besides when the male pops in for a shift change.” (I feel this on the Highland Avenue aspect of the steeple.)
Eckert Road, Ohio River: As of 5 April Jeff Cieslak reviews {that a} peregrine pair is close to the Eckert Road nest website however they don’t look like nesting there. He says it’s the identical feminine, in all probability a brand new male.
Sewickley Bridge, Ohio River: Jeff Cieslak reviews: “On a number of visits throughout March, one or two falcons had been fussing round below the bridge, close to the far pier. On April 3, two had been noticed in what seemed to be a nest alternate 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 should have failed. eBird reviews from the “Mouth of the Beaver River” hotspot in late March by 2 April point out that each peregrines are seen concurrently. Undoubtedly 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 photograph from 23 March. Since this website was profitable up to now, it seems to be promising for a household this yr.
Each potential website is listed under …
and also you’re in all probability questioning …
When will the eggs hatch? … How about TODAY? see under
The standard calculation is “34 days after incubation begins,” although normally 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 alternate on 4/3; Hatch on or earlier than 7 Might … in all probability earlier than.
- Tarentum Bridge: Noticed incubation 3/7; Hatch on or earlier than TODAY 10 April!
