Schenley Park Outing to See the Owls, Sun 2 March, 9:30

Birds of Prey, Books & Events, Schenley Park

1 March UPDATE: Yes this outing is happening as planned and yes it will be COLD. Dress warmly. Here’s some news:

  • One of the owlets fell from the nest on Thursday 27 Feb and was rescued by Sarah Mateskovich & taken by WIN to Tamarack Wildlife Center where they determined it has only a minor beak injury. The rescued owlet may be fostered at another nest since this bridge nest is inaccessible for her return.
  • As of 28 February there were still 2 owlets in the nest, apparently there were 3 to begin with!

23 February 2025

You’ve been hearing about them. Now come see them!

Join me on a daytime great horned “owl prowl” in Schenley Park on Sunday 2 March 2025. Meet at 9:30am in front of the Schenley Park Visitor Center (40.438514, -79.946479). We’ll walk from there to the viewing area.

NOTE the time! 1 HOUR LATER THAN USUAL!     9:30AM

Dana Nesiti photographed two owlets in the nest on 19 February, above. Since this outing is 11 days after his photo I expect the owlets to be halfway to adult size.

Dress warmly in layers and wear comfortable WARM socks and boots. Bring binoculars, field guides and a scope if you have them. We probably will be standing still on frozen ground while we wait for the owls to move. This is a very cold activity so be prepared!

The outing will last 60+ minutes, depending on the weather.

And just to tantalize you, here’s what they looked like this morning

17 February 2025

It was overcast with misty rain when Dana Nesiti visited Schenley Park on Saturday 15 February to capture photos of the great horned owl’s nest. As you can see, the owlet is growing fast and starting to get facial disc feathers. (You can also see raindrops on the back of Dana’s camera, below.)

For comparison, here’s what the owlet looked like 4 days earlier on 11 February — all beak.

Hoping for a good look at the owl family, Charity Kheshgi and I visited Schenley yesterday while it was sunny. Unfortunately the wind was so cold that the owlet hid beneath his mother’s belly feathers while her ear tufts flapped in the wind.

We did, however, find the father owl roosting in a tree on the opposite hillside — in the sun and out of the wind.

Today it’s so cold that the owlet will be hiding. Next weekend’s above freezing temperatures will be a good time to check on his progress.

Eagle Egg at Irvin

16 February 2025

In case you missed it, the bald eagle pair at the US Steel Irvin nest welcomed their first egg of 2025 on Thursday afternoon 13 February. WTAE reports:

WEST MIFFLIN, Pa. — The bald eagles living at U.S. Steel’s Irvin Plant have welcomed their first egg of 2025.

Mother Stella laid the egg around 5:30 p.m. on Thursday.

Stella joined Irvin in the nest after Claire left late last year. Irvin has lived at the nest for six seasons.

The egg could hatch in as little as 35 days and be the eighth eaglet born at the nest.

— WTAE: Bald eagles welcome first egg of 2025 at U.S. Steel Plant nest

This is happy news since nesting at Hays looks doubtful after months of disruption by several immature eagles. Though the breeding season could be salvaged at Hays by a strong driven pair, that type of pair bond has not developed yet this spring.

A similar though very short drama occurred last fall at USS Irvin resulting in a new couple with a strong bond: Stella and Irvin. Learn about their history in this video from KDKA.

Seen This Week: A Gull, 4 Merlins, and 60 Feet into Ohio

15 February 2025

Welcome to Day Two of the Great Backyard Bird Count (GBBC). I’m staying indoors while it snows and rains so much that …

FLOOD WATCH REMAINS IN EFFECT FROM 7 AM EST THIS MORNING THROUGH SUNDAY EVENING...Flooding caused by excessive rainfall continues to be possible.
— National Weather Service forecast for Pittsburgh PA 15 Feb 2025

Gull: Since most of the rain will fall south of here the Monongahela River will rise again. It was falling last Tuesday when I photographed one of the many ring-billed gulls at Duck Hollow. This one seemed to be asking, “Do you have food for me?” Someone had left birdseed on the trash can cover.

4 Merlins: Yesterday I went to the Bob O’Connor Golf Course at Schenley Park half an hour before sunset to see if I could find the two merlins who usually hang out there. As soon as I arrived one flew in and landed on the highest pine in the Palmer Loop Practice Area north of Schenley Drive.

Soon a second merlin landed on top of the tallest tree, a bare tree between holes 8 and 9. I walked a big circle to check for songbirds and saw the first merlin in an intense chase with a third. On my way back to the car I found a fourth(!) and was able to stand in one spot and see all four merlins at the same time.

Four is unusual but I remember a time, perhaps in the late 1990s, when Bill Hintze first found merlins at the golf course. In those days there were sometimes as many as four.

60 Feet into Ohio: On Monday 10 Feb four of us went birding on the Stavich Bike Trail in Lawrence County PA to do a Winter Survey for the Third PA Breeding Bird Atlas. We were ready to head back to the car when I realized we were only a half mile from Ohio. So we kept going, crossed the state line and walked 60 feet into Ohio.

Ta dah! Here we are just inside Pennsylvania. Best Bird: a white-crowned sparrow.

11 February 2025

Remember this great horned owl nesting in Schenley Park? According to eBirder Andy Georgeson, she’s been incubating since at least 8 January.

[Great horned owl] continuing – I have now observed this owl on the old red tail hawk nest for the last 3 weeks. … This morning the owl was mobbed by 2 Ravens and displayed a defensive posture while in the nest before the Ravens flew off.

— eBird Checklist comment from Andy Georgeson, 29 Jan 2025, 7:30am

Last Sunday, 9 February, Dana Nesiti saw movement under her breast feathers and patiently waited until her owlet appeared. Can you see its little gray beak poking out under her white collar?

Incubation for great-horned owls (Bubo virginianus) lasts 30-37 days, averaging 33 days. If this owlet hatched on Saturday 8 February, its egg was laid around 6 January. Andy Georgeson’s observation supports this timing, too.

Great horned owlets are in their nestling phase for 42 days. This one will probably walk off the nest (called “branching”) on or around 22 March.

We’re going to have 6 weeks of Superb Owlet(s)!

UPDATE at noon on 11 February: Charity Kheshgi and I visited Schenley Park this morning to see the owls, best viewed in the vicinity of the stone bench here. I was lucky to digiscope a photo of the chick.

The owlet is the white fluff closest to his mother in the center of the photo. The other white stuff is the remains of a rabbit on top of the twigs at the left.

If you can’t discern the owlet above, here’s the same photo flipped so that the chick’s sleeping face is in the normal upright position. Ignore everything in this marked up photo except the area inside the yellow circle. Notice that the owlet’s white head, dark eye (closed), and beak are peeking out to the right of the nest twigs.

Plucky Crows Harass Bald Eagles

Bird Behavior, Birds of Prey, Crows & Ravens

4 February 2025

Bald eagles are top predators who will eat crow nestlings, fledglings and unwary adults if the opportunity arises, so crows learn from a very young age to watch out for eagles.

Even in the nest young crows hear and see their parents drive off hawks and eagles. In their first year of life, which they spend with their parents, they learn the rules of harassment.

  • When a lone crow sees an avian predator he perches prominently and calls for reinforcements.
  • When his buddies arrive the crows work as a mob to drive away the predator.

  • When the situation is acute and the mob is left behind, a solo crow may harass an eagle even though he’s the only one left. Sometimes he does something daring.

Ten years ago photographer Phoo Chan went to the shore at Seabeck, Washington to photograph the bald eagles who arrive in large number during the midshipman fish run (Porichthys sp). He was very lucky to capture photos of a lone crow riding on an eagle’s back. See more in his article below.

In the past week I’ve been lucky to see gulls on ice, an owl on the nest, and three Bonus Birds.

Tiny icebergs were floating down the Monongahela River when Charity Kheshgi and I visited Duck Hollow on 28 January.

Ring-billed gulls outnumbered every other species. A few immature herring gulls made a ruckus in the middle of the river. And a Bonus Bird: A peregrine falcon flew over. I wonder who it is!

On 1 February I visited Schenley golf course to take a photo of my shadow and decided to drive down Circuit Road on the way home. The sun was so bright that it illuminated the great horned owl’s nest under the Panther Hollow Bridge. From the road I digiscoped a photo of the female and cropped it for a closer look.

Yesterday I went back with Charity Kheshgi to see the owls. The captions on her video and photos tell the story.

We were able to see both the male on the left and the female on the nest from a trail on the same level as the nest (the “Lower Trail”).

Below the bridge we couldn’t see the nest but the male was visible, roosting in the shadows.

Great Horned Owls Already on Eggs

30 January 2025

Great horned owls (Bubo virginianus) are the first birds to nest in Pennsylvania each year(*). They start courting in late fall and become really intense in December when you often hear them hooting in the woods and suburbs.  By January or February they’ve chosen a nest site and the female lays her eggs.

Since great horned owls never build a nest they often take over an old red-tailed hawk nest and that’s what they did at this bridge in Oakland. Ankur and Wenting saw the pair last Sunday 26 January.

The female owl is the only one who incubates, so she’s on the nest in the photo. Look closely behind and above her and you will see her mate perched on a horizontal girder. He feeds her at night and roosts near her during the day.

According to eBirder Andy Georgeson, this female has been on the nest since around 8 January:

[Great horned owl] continuing – I have now observed this owl on the old red tail hawk nest for the last 3 weeks. … This morning the owl was mobbed by 2 Ravens and displayed a defensive posture while in the nest before the Ravens flew off.

— eBird Checklist comment from Andy Georgeson, 29 Jan 2025, 7:30am

Look at old red-tailed hawk nests near you for some ear tufts sticking up. If you see them, don’t get too close!  You don’t want to tangle with Mama owl!

Snowy Owl? Or Plastic Bag?

Is that a snowy owl? Franklin County, PA 12 Jan 2014 (photo by Nancy Magnusson via Flickr Creative Commons license)

23 January 2025

Those who ventured out in this week’s bitter cold hoped to see birds from the far north who had just arrived on the wind. The typical way to find them is to drive past frozen fields watching for movement and scanning for anything that looks like a bird.

What’s that white lump in the field? Is it a snowy owl? Or a plastic bag?

Eleven years ago the winter of 2013-2014 was extremely cold and there was a huge irruption of snowy owls in the Northeast and Great Lakes. People photographed all of them, even the distant ones, to document them in eBird.

At top: Is that a plastic bag on that patch of snow? Below: Are there plastic bags or snowy owls in this photo? And how many?

Where’s the snowy owl? There are 3 in Jackson County, MI on 26 Dec 2013 (photo by Don Henise via Flickr Creative Commons license)

Is there a snowy owl in this picture?

Answer: All three photos have a snowy owls in them. The middle photo has 3 along the ridge top.

This winter we have not seen a big influx of snowy owls into Pennsylvania though there have been a couple of sightings.

Recently there’s a snowy owl near Grantsville, Maryland which is often photographed from afar. A white lump?

Hays Bald Eagle ‘Dad’ is Back!

Birds of Prey, Nesting & Courtship

20 January 2025

From 2013 through 2023 a male bald eagle, nicknamed ‘Dad’ by his fans, nested at Pittsburgh’s Hays site. Here he is adding sticks to the nest in November 2018.

Male bald eagle, ‘Dad’ adds sticks to the Hays nest in Nov 2018 photo by Dana Nesiti, Eagles of Hays PA)

Sadly ‘Dad’ disappeared from his territory in September 2023 and many feared he was dead. A new male, HM2, mated with the original female in 2024 and she laid one egg but the nest failed when the egg deteriorated and collapsed.

Then on a gray and rainy morning, Saturday 18 January, Dana Nesiti (Eagles of Hays PA) was taking photographs at the Hays nest viewing site when an adult eagle came in, perched, and flew. Dana’s in-flight photos show that this bird has ‘Dad’s unique traits: a wing gap and a stubby talon.

It didn’t take long to spread the happy news. ‘Dad’ eagle is back!

With Dad’s return hope is renewed for a successful nesting season even though it’s already late January. As Merry Wander commented on Facebook:

…and Dad only needs 4 days to whip this place into shape…

Woo hoo!

p.s. If you aren’t on Facebook you won’t be able to see Dana’s entire Facebook message. I’ve quoted it below.

“1-18-2025 Got to the trail while it was still dark and was able to see a eagle in the cam tree with binoculars. While I was watching that eagle it flew out at 7:22am and circled the river a couple times before flying downstream. It appeared to be a sub adult. I continued down the trail to the nest area and took my pack off and was going to get set up. Another eagle was flying down the hillside which looked like a sub adult and it had a adult eagle chasing it. They did some maneuvers and also flew downstream. It was still dark and my camera was in my backpack.

“At 9:20am a eagle came over the hill and landed in the slanty tree area and sat for a few minutes. When it flew we were shocked. This eagle appears to be the original Hays male “dad”. I’m 99.999% sure it is. What do you think?

“EDIT: Looking at other images from the flight of the hill, we can see the top wonky feather and his stubby talon. I’m saying 100% the original male!!

“There have not been any signs of nest building that we are aware of and the past week there have been several different sub adult eagles hanging around. Sorry for the bad quality pics as the sky was drab and rainy.“
