13 July 2024, Pittsburgh
Hot. Sultry. This week’s oppressive heat and humidity was curiously exhausting. Where have I experienced this weather before? Ah, yes. Florida in July. For the most part I stayed indoors so there’s not much “Seen This Week.”
On a brief foray around the Cathedral of Learning I did not find the peregrines but did see a beautiful flowerbed of black-eyed susans.

The peregrines cope with the heat by perching in the shade. Carla looks sleepy an hour before sunset on 9 July.

I’m not looking forward to next week’s heat wave, though it won’t be as bad in Pittsburgh as further east.
We complain about staying indoors during winter but now we’re staying indoors in the summer, too.

During spring warbler migration I try to see as many species as possible as they pass through Pennsylvania and Ohio. Unfortunately, I missed some of my favorites this year, most notably the Canada warbler (Cardellina canadensis), so Charity Kheshgi and I went to Laurel Mountain last Sunday to find them on their breeding grounds.
We thought we’d be able to see at least one of the two Canada warblers we heard singing along Spruce Bog Trail, but not. However, we got lucky on the Picnic Trail when the bird pictured above and below approached us making his warning call.

Here’s an example of what he sounded like:
There was plentiful shade in the forest, but that made the birds harder to see. This ovenbird (Seiurus aurocapilla) is nicely lit but still in the dark.

We found other delights on the mountain. A tiger swallowtail butterfly sipped nectar from pitcher plant flowers at Spruce Bog.

Pennsylvania’s state flower, mountain laurel (Kalmia latifolia), was in bloom.

We heard more birds than we could see, ultimately tallying 24 species in our checklist here.

Between the glory of woodland spring ephemerals and summer’s splash of native field flowers, June has fewer blooming natives. On a walk yesterday along the Three Rivers Heritage Trail near Millvale I found a host of pretty flowers, many of them invasive.
Orange day-lily (Hemerocallis fulva) is native to Asia and well established in Pennsylvania. You’ll see it blooming in ditches, along railroad tracks and in gardens. It pops up in so many places that it has at least 10 common names. Orange day-lily is considered invasive in Pennsylvania because its tubers create thick clumps that crowd out native plants in sensitive habitats.

What’s that popcorn-like smell? It’s poison hemlock (Conium maculatum) and it’s in bloom. You won’t want this plant anywhere you find it. Here’s how to get rid of it; expect a multi-year effort.)

Leaf-out reveals the browseline, Schenley Park, 5 May 2024 (photo by Kate St. John)
11 May 2024
This week I photographed a few puzzling objects for the record.
When I took a photo of Full Leaf trees in Schenley Park on 5 May I noticed something newly visible in the presence of leaves. Can you see it?
Look at the center of the photo where the path disappears in the distance. Above the path is a gap that allows you to see further under the trees. The gap flows to the right and follows the contour of the hillside. That’s the browseline, the cumulative effect of too many deer eating at the same location over and over.
I saw a native(!) honeysuckle this week. Pink with fused leaves, it’s called limber or glaucous honeysuckle (Lonicera dioica).

Was this a cattle egret at Moraine State Park? If so it was a rare bird! Nope. It’s a white bag.

On 3 May a leaf-footed bug appeared to walk across the sky.

We’re more than a week into May now, so it’s likely you’ve seen the tigers and tents that first appeared in late April. If you haven’t, here’s who they are.
Tigers
I first noted tiger swallowtails at Enlow Fork on 25 April but I remember seeing one earlier in Schenley Park. When was your earliest tiger swallowtail?
Find out more about them in this vintage blog: Flying Tigers
Tents

I saw the first tentworms on 30 April in Frick Park, but it seems this is not a big year for them. I haven’t seen many other tents. Did you know that tentworms are a favorite food of yellow-billed and black-billed cuckoos? Have you seen a cuckoo yet?

Since our last spring checkup six weeks ago, Pittsburgh has galloped into summer. Last weekend we had July-in-April weather with official highs of 83°F and even higher in town.
Pitt peregrine Carla felt the heat at 10am on 29 April as she shaded her chicks and gular fluttered (panted) to cool herself off.
Pittsburgh is not alone. In a wide swath of the U.S. from Iowa to New York spring was 20+ days early this year. In Pittsburgh nearly half of April was more than 10°F above normal while we had only one cold day at 12°F below normal.
So what temperature should we expect if we’re only 20 days ahead of schedule? April 29th ought to have been like a normal 19 May but it was way beyond that.
The heat prompted the trees to leaf out early and flowers to bloom ahead of schedule. Maples and buckeyes are in full leaf now and our oaks are at flower+leaf stage as shown at top. The leaves are hosting food for birds in the form of tiny caterpillars, so …
Migratory birds are taking advantage of the south winds and early leaf out. Since 27 April we’ve seen our first scarlet tanagers, rose-breasted grosbeaks, Baltimore orioles, indigo buntings and warblers.
Charity Kheshgi has been documenting our good luck with warblers at Frick Park. Notice the size of the leaves in her photos!
p.s. And where am I? Right now I’m at Magee Marsh a week ahead of The Biggest Week in American Birding. I don’t expect to see the swarms of migratory birds that will be here next week (I’m leaving on 3 May) but I’ll learn what happens before the people show up and why everyone waits until next week. 😉
Last Thursday four of us made our annual pilgrimage to Enlow Fork on the border of Washington & Greene Counties(*) to look for wildflowers and birds. We saw carpets of blue-eyed Mary as well as fire pink, wild geranium and dwarf larkspur in both blue and white. (Can you see the tiny spider on the fire pink petal, above?)

Record-setting rain in the beginning of April left flood debris in the valley. Donna Foyle photographed the fallen trees that nearly hit the pedestrian bridge.

I tried to capture the water-swept mud and flood depth by photographing debris stuck in the trees. The high water mark here was up to my chin.

The floodwaters swept freshwater clams from their homes leaving their empty shells among the flood debris.

We didn’t see many birds at first, perhaps because it was so cold. By the time we were ready to walk back it had warmed up enough to see my First Of Year Baltimore oriole, rose-breasted grosbeak and scarlet tanager deep in the woods.

We also saw or heard seven warblers including Louisiana waterthrush, common yellowthroat, northern parula, redstart, Nashville, yellow and yellow-throated warblers.
At one point I put my bright hat (on top of my sun hat & headband) in case a distant wood thrush would notice. The thrush did not, but I earned the name “Golden-crowned Katelet.”

We had a great day among pale spring leaves and blue-eyed Marys.

Next week will be much warmer. Bring on the birds!
(*) Where is Enlow Fork?
The Enlow Fork of Wheeling Creek forms the boundary between Washington and Greene Counties in southwestern PA. When we say “Enlow Fork” we are referring to the northern section of PA State Gameland #302 on both sides of Enlow Fork creek. The Gamelands (unpaved) parking lot is at this pin drop: https://maps.app.goo.gl/uzw42KqYZexLP4AB6.

Do you ever feel frantic in the Spring?
This week in Pittsburgh the highs were always above 60°F and three days were in the low 80s. Migratory birds came in a rush midweek while early-blooming flowers went to seed. Spring came so quickly that I couldn’t keep up. It’s enough to make you frantic.

There were some stunningly clear days this week but the partly cloudy ones were more interesting, especially at sunrise: Duck Hollow on 15 April and Oakland on 19 April.

On Thursday 18 April Charity Kheshgi and I saw great birds in Frick Park.
The trees in town began the week with tiny pale green leaves; Some ended the week with large dark green leaves. American bladdernut (Staphylea trifolia) was blooming yesterday in Schenley Park.

Last week was so full of news, from peregrines to floods, that I had to skip my usual “Seen This Week” report. Meanwhile Spring isn’t holding still. Wildflowers are blooming and the early ones have already gone to seed. Here’s a selection of my best photos from last week, April 8-11.
Above and below, three photos from Frick Park. All of these are alien and some are invasive but they are pretty.
Speedwell’s (Veronica persica) tiny flowers bloom in fields and lawns. A dewdrop dangled above this one from a blade of grass.
Lesser Celandine (Ficaria verna) is abundant along creeks and river banks including Duck Hollow and Nine Mile Run. Very invasive, but pretty, which is why it was imported as a garden plant.

Last Thursday I visited Barking Slopes for just an hour before the rain chased me away. Even though I didn’t have much time I saw more than 15 species in bloom including:

This week March went out like a lamb and April came in like a lion.
After photographing garden flowers on Easter morning I traveled out to Independence Marsh in Beaver County. I did not find my target bird, rusty blackbirds, but I did find spring flowers: Dutchmans breeches, cutleaf toothwort, bloodroot (above) and the first tiny bloom on shooting star (below).

As soon as March was over, things went wrong. I should have known when I saw this troubled sky of mammatus clouds on Saturday, 30 March. Not a good sign.

It rained and rained and rained on April 1-3, setting a record of 2.68 inches on April 2. Streams and basements were hit hard while the rain was falling. The rivers rose, as shown at at Duck Hollow on 4 April with the Monongahela River at parking lot level. (more flood photos and videos here)

Later that same day, Thursday 4 April, the temperature fell and so did graupel.

Today it’s cold but the precipitation has finally stopped.
Meanwhile ….Remember those beautiful tulips I posted last Sunday, Easter morning?

And remember the deer I saw between two highrises in Oakland on 24 March?

Well, the two met up and the tulips did not fare well.
