Coltsfoot gone to seed, Frick Park, 9 April 2024 (photo by Kate St. John)

16 April 2024

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.

  • Coltsfoot (Tussilago farfara), at top, is found in disturbed soil.
  • 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:

6 April 2024

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.

30 March 2024

A Wednesday trip to Moraine State Park was cold and gray but quite worthwhile. We saw 300(!) red-breasted mergansers, many ring-necked ducks, blue-winged teal and a rare bird — a trumpeter swan. Charity Kheshgi’s photos show off the teal and swan.

Trumpeter swans (Cygnus buccinator) are “the heaviest living bird native to North America and the largest extant species of waterfowl.” They were nearly extinct in 1933 — only 70 remained in the wild — but several thousand were then found in Alaska. “Careful re-introductions by wildlife agencies and the Trumpeter Swan Society gradually restored the North American wild population to over 46,000 birds by 2010.” The trumpeter at Moraine is one of their descendants. (quotes from Wikipedia)

Spring is 20 days early in Pittsburgh this year. To prove it the yellow buckeye trees were in near-full-leaf on Thursday 28 March in Schenley Park.

They are 8 days later than the astoundingly early spring of March 2012. Click here to read about that year.

Early spring is the hungriest time of year for deer in Pennsylvania because they’ve already eaten all the easy-to-reach food. When the deer population is greater than the area’s carrying capacity they seek out food in unusual places. Thus I was amazed but not surprised to see a deer browsing the bushes next to our highrise at 5:30am. There is nothing to eat down there. There is nothing to eat anywhere near here.

This week non-native flowering trees put on a show in the city of Pittsburgh. Originally from China and Japan their growing season is earlier than our native trees.

This month’s three-day spurts of highs in the 60s and 70s prompted the red maples to flower and start producing seeds.

Last Saturday I visited Wolf Creek Narrows, almost an hour north of Pittsburgh, where the growing season is later than at home. There we found an interesting jelly fungi called witches butter (Tremella mesenterica) …

… and a decapitated skunk cabbage that allowed us to see the spadix inside. The hood usually covers this structure but something ate the hood. What animal could put up with the odor to eat that hood? And then the animal would vomit because the plant is toxic.

I promised you an owl.

Inspired by Steve Gosser‘s photo of an American woodcock at North Park Upper Fields on 4 March, two of us stood out in the cold on Thursday evening waiting for sunset and for American woodcocks to make their twittering courtship flights. The sky was clear and the moon was so bright that we had moon shadows. It was also 5°F colder than at home in the city and I brought the wrong gloves. Brrrr!

Despite the cold it was worth the trip. Half an hour after sunset three American woodcocks put on a show and two flew right past us on their way to the sky.

But the big surprise of the evening came before the woodcocks. Karyn saw a great-horned owl fly out of the pines and land on top of a brush pile. The owl was hunting while the voice of a youngster begged for food from pines.

Meanwhile a second adult owl flew to a bare tree at the other end of the field where we could see its silhouette against the glowing sky. Though my cellphone is not good at distance photos, you can faintly see the ear tufts that prove that this second bird of prey is a great-horned owl.

After a slow start to spring in the southern part of the U.S., spring is spreading more quickly now across the central part of the country. Des Moines, IA is 20 days early, Detroit, MI is 23 days early, and Cleveland, OH is 16 days early compared to a long-term average of 1991-2020.

Though it’s only 23°F this morning in Pittsburgh we, too, are having a very early spring. Just three days ago I photographed daffodils and many flowering trees in my neighborhood.

Today’s low temperature feels like an aberration compared to what we’ve come to expect this “winter” with highs in 60s and 70s. Dark red on the map below shows how early spring is across the continental US. In Pittsburgh it’s 20 days early.

Four days this week were unseasonably warm with highs 18 to 20+ degrees above normal. The flowers and birds responded.

On Tuesday, Charity Kheshgi and I heard a fox sparrow at Frick Park but he was elusive. We spent a long time trying to get a good look him until a blue jay’s weird call made us pause. So did the fox sparrow, as shown above in Charity’s photo.

On Wednesday there were few birds at Toms Run Nature Reserve but we saw purple dead nettle (Lamium purpureum) in bloom.

On Thursday 14 March I was surprised at the lack of birds at Raccoon Creek Wildflower Reserve, but the flowers on the Jennings Trail cliff face (bordering the creek) were responding to the heat. It’s not Full Blown Spring yet but I found:

The weather doesn’t know what to do with itself in Pittsburgh. Some days it rains all day (today for instance). Some days it’s hot and sunny. Some days it’s chilly and overcast. This week we saw it all.

On Monday and Tuesday hot sunny weather (74-75°F) encouraged everyone to get outdoors. I waited a while to get a photo, above, without a lot of people in it. Just around the bend the sun was so low in the sky at 4:40pm that it made long shadows.

That beautiful day came after a foggy rainy weekend, seen at Duck Hollow below. The Monongahela River was running high because of all the rain.

All kinds of critters were busy this week including a striped red ant on a trail in Schenley Park. What ant is this? Can you tell me its name?

On Monday I also found two refugees from water-logged soil on a sidewalk in Oakland. Not earthworms, these are invasive Asian jumping worms. Not good! Click here to see a brief clip of them squirming.

On Thursday 7 March I found new leaves of (maybe) corydalis at Todd Nature Reserve.

And on the way home I stopped at the Tarentum Bridge to check on the peregrines. The male was perched nearby while the female incubated eggs in the nest. This (lousy) digiscope photo shows the female’s wingtips visible in the nest box as she incubates with her tail toward us. This is early for most peregrines in southwestern PA but not for this bird. She’s always early.

Despite a few cold snaps, this winter has been quite warm in Pittsburgh and the plants are responding. During the past ten days I’ve found:

  • Woodland crocuses (Crocus tommasinianus) blooming in the grass on Neville Avenue and at Schenley Park,
  • Skunk cabbage (Symplocarpus foetidus) at North Park,
  • Flowering cherry trees blooming at Carnegie Museum.

Despite these signs of spring the overall look of the land is brown. Last Sunday, 25 Feb, I took a walk with the Botanical Society of Western PA at Hays Woods where I learned a new grass.

Grease grass or purpletop (Tridens flavus) is a native bunchgrass whose seeds are oily, hence the grease name. Claire Staples holds it against a dark background so we can see the seeds.

On Thursday I found several species of honeysuckle (Lonicera sp.) leafing out in Schenley Park.

Honeysuckle leafout is an spring indicator on the National Phenology Network (USA NPN) so I wondered about the status of spring elsewhere. On 26 February USA NPN wrote:

How does this spring compare to “normal”?
After a slow start to spring in Florida and parts of the Southern Great Plains, spring is spreading more quickly now across the country. Albuquerque, NM is a week early, St. Louis, MO is 2 weeks early, and parts of Washington, D.C. are 22 days early compared to a long-term average of 1991-2020.
