I’ve known for years that chimney swifts eat flying bugs as they zip around above us but I didn’t think about the variety of insects they encounter. Now that I live in a high-rise flying insects sometimes perch outside my window. This elegant bit of “chimney swift food” visited my window more than a week ago.

This week I spent four days birding at Magee Marsh, Ohio on Lake Erie’s shore where I saw 113 species including 20 species of warblers. See my eBird trip report here.

The warblers were on time but the plants were late compared to Pittsburgh. Places near the lake have a later growing season because water temperature changes more slowly than land and influences local weather. Instead of deep green leaves, the trees had tiny leaves and the oaks were still flowering.

Woodland wildflowers were also still in bloom. At Pearson Metropark in Oregon, Ohio I found wild geranium (Geranium maculatum), star-flowered lily-of-the-valley (Maianthemum stellatum) and wild ginger (Asarum canadense).

Star-flowered lily-of-the-valley (Maianthemum stellatum)

This blooming plant was new to me: American black currant (Ribes americanum)

On the subject of green things, last weekend in Schenley Park this small cascade pond on Phipps Run was too green with clumpy algae. Algae is unusual for Phipps Run. Something went wrong … but what?

Tomorrow is the big Enlow Fork Extravaganza at State Gamelands 302 on the border of Washington and Greene Counties. Known for its wildflowers and birds, the site is called “Enlow Fork” because its defining feature is the creek that runs through it, the Enlow Fork of Wheeling Creek.

Though tomorrow’s weather looks like rain, my friend Barb Griffith and I had a nice day there on Wednesday April 26.

We saw 45 species of birds including First of Year gray catbird, Baltimore oriole and American redstarts (checklist is here). We were disappointed not to find any wood thrushes, scarlet tanagers or rose-breasted grosbeaks though we have seen them there in late April in years past.

Spring leafout at Enlow Fork was late compared to the City of Pittsburgh, even though Enlow is 40 miles south of town. The side-by-side photos below show leafout at Schenley Park and at Enlow Fork on virtually the same day. I didn’t expect our urban heat island to make that much difference.

Lack of leaves and much less deer browse made the wildflowers superb. Here are just a few of those we saw. As always, if I’ve misidentified any, please let me know.

This week in Pittsburgh began 15 degrees above normal, dipped to freezing (10 degrees below normal), then soared back into the 80s. The flowers and leaves coped.

On Saturday 15 April I visited Harrison Hills Park and found busy insects pollinating Virginia bluebells, golden ragwort, spring beauties and garlic mustard.

Garlic mustard is in bloom everywhere right now but I rarely take a picture of it.

On Monday 17 April at Schenley Park, jetbead, greater celandine, and common blue violets were in bloom.

The poison ivy leaves were small on Monday but are much larger now.

By yesterday, 21 April, the redbud was seriously leafing out in Schenley.

These two photos show Schenley’s leafout progress: The first below is a yellow buckeye near Anderson Playground on 17 April. The second is the same yellow buckeye 4 days later! It’s hard to see Panther Hollow Lake through the trees.

New birds! Yesterday I saw my first of year house wrens and chimney swifts (my Schenley eBird checklist here). Today I’ll dodge the raindrops to find the wood thrush reported by friends near Circuit Drive / Serpentine Road.

Happy Earth Day!

During February’s heat wave I was sure Spring would be extremely early this year in Pittsburgh. Then temperatures dropped in March and everything paused. Yesterday the flowers on this red maple were giving way to seeds while the leaf bud was opening. Is this normal for early April? It’s time for a Spring checkup. Where are we now?

Spring’s progress is easy to see in this USA National Phenology Network animation. Leaf out raced northward in February producing dark red-brown in the places with an earliest Spring on record. In mid-March the racing stopped and gave way to paler red across PA and New York state. But what’s the dark blue in Kansas and the Southwest? It’s a very late Spring.

[As of 10 April 2023] Spring is 11 days late in Denver, CO, 2 days late in Chicago, IL, and 2 days early in Albany, NY. The West is mostly late. Yakima, WA is 12 days late, Boise, ID is 20 days late.

Most of Pennsylvania is close to normal compared to baseline years 1981-2015. Pale green is OK. Dark green is not. Southcentral and southeastern PA were off-the-chart early.

As you can see by the splash of color on the map, bush honeysuckle, the Spring leaf out indicator, has finished in Pennsylvania. You can follow the progress of spring blooms and check on the rest of the country at USA National Phenology Network.
