Seen This Week: While out birding on Tuesday I noticed blooming flowers and unusual leaves at Raccoon Creek Wildflower Reserve. Mitrewort (Mitella diphylla), at top, is one of my favorites because of its delicate, intricate flowers.

This red leaf gall caught my attention, but the bulk of it is under of the leaf and colored green (second photo). Does anyone know the name of this gall?

Meanwhile jack-in-the-pulpit (Arisaema triphyllum) is blooming in Schenley Park. I could not resist raising his lid.

A study seven years ago of bird population trends predicted that climate change would cause most species to decline while a few would increase. In May 2016 I wrote about two species whose fates would be different.
The maps below show population trends during the non-breeding season. The white-throated sparrow’s trend map for 2007-2020 indicates their abundance dropped 30% in the lower Mississippi area and on the East Coast from New York to North Carolina.
I’ve noticed the drop in white-throated sparrows during their peak migration in early October and mid-to-late April. American robins seem the same as ever here in Pittsburgh
Have you seen a change in white-throated sparrows? Let me know.

The new female peregrine, Carla(*), has been at the Cathedral of Learning for only a few days but is quickly becoming acquainted with the territory and her new mate Ecco. Yesterday they made courtship flights around the building and bowed at the nest several times.
Though it seems late in the season to start nesting, the snapshot camera shows Carla exploring the nest and the pair’s interest in each other. (The slides repeat automatically.)
#1. Ecco calls to Carla, “Come down from the nestbox roof.” When she doesn’t, he leaves and she asks him to come bow.

For the eighth consecutive year, falcon father Jamie and mother Moxie squawked loudly and angrily Monday as their baby chicks that hatched atop Indiana Michigan Power Center (IMPC) were briefly removed from their nest to receive identification bands.
The three male chicks were named Bolt, Unity and Artemis, and the one female was named Carla.
… We used the opportunity to invite I&M employees to select the names – and they submitted more than 650 names for consideration.
… [The name] Carla is in recognition of one of I&M’s respected leaders, who is retiring this summer after more than 30 years with the company.
Who is Carla’s namesake? I contacted Tracy Warner in Media Relations at Indiana Michigan Power, a subsidiary of AEP, and he confirmed that Carla the Falcon was named for Carla E. Simpson who retired in the summer of 2020.
Carla Simpson started as a clerk/cashier in 1988 and by the time she retired was a director of the company and listed in the Annual Report. Interviewed in 2017 for the AEP Retirees newsletter, Carla Simpson said something that really resonates with me.
Q (asked of Carla E. Simpson): What is the biggest challenge you have faced and overcome in your career at AEP?
A: The biggest challenge I have faced as a woman is not being heard at times. Sometimes I can make a suggestion or statement and it is overlooked, but another person may make the same suggestion and be heard. This is a challenge that I have not yet overcome but I am working on it. It sometimes requires me to restate what I said or ask for clarity as to how the other person’s suggestion or statement is different from mine.
West End Bridge peregrine viewing (Google map marked up by Jeff Cieslak)
The female was banded and by 4 May Jeff finally got a shot of her bands pictured below. Jeff wrote, “This kinda looks like S/01 Black/Blue? Could be green. …. [The bird] flew off and dropped a feather into the river, P5 left, I think, and that pretty much confirms that it’s the female.”

I can understand why Carla left the West End Bridge for the Cathedral of Learning. In 2020 she hatched on a 27-story building, the Indiana Michigan Power Center.
She is now preparing for a long stay on a 40-story building, the University of Pittsburgh’s Cathedral of Learning, as seen from Flagstaff Hill in Schenley Park below.

You can watch Carla and her future mate, Ecco, on the National Aviary Falconcam at the Cathedral of Learning. It is probably too late in the season to start nesting so they won’t be on camera frequently. However Carla and Ecco are getting to know each other and that may involve bowing at the nest. Wait and see.
In Sunday’s update I explained that Morela was very ill when she disappeared last Friday and said: “If Morela is gone a new female will come to the Cathedral of Learning to be Ecco’s mate.” Well, that didn’t take long! A new female peregrine showed up at 2:00pm and displayed her bands. I already know where she came from.
Yesterday was so warm and sunny that Ecco sunbathed for 90 minutes at midday. Then at 2:00pm a new female peregrine showed up and sunbathed for half an hour. (See slideshow at end.)
Summary: This month Morela became progressively ill and disappeared on 12 May. She is presumed dead.
Two weeks ago I wrote that there would be no peregrine eggs this year at the Cathedral of Learning because Morela was unable to lay any. She crouched and strained but appeared to be egg bound.
Since then Morela has had days when she looks very ill, then seems to recover a little, then looks ill again. Though she stopped standing over the scrape as shown above, she has not returned to her formerly energetic self. Her bleary eyes indicate she feels unwell.
He does what he can by bringing her food which he prepares more carefully than usual, as if he’s making it easy to eat. Unfortunately it is not enough.
On the morning of 7 May Morela felt bad enough that she left the nest for 36 hours. That day I found her facing the wall in the 38th floor southeast cache area.
She returned to the nest at 5:34pm on 8 May and seemed slightly better but in the next few days her health declined. In this snapshot she is leaning to the side, something she never did when healthy.
During a difficult night on May 11-12 Morela leaned a lot and may have lost her balance a couple of times. On Friday 12 May at 5:51am she left the nest and has not been seen since.
Her long absence and ill health indicate Morela has probably died.
Life goes on in the peregrine world. If Morela is gone a new female will come to the Cathedral of Learning to be Ecco’s mate. This year it’s too late to raise a family but if all goes well there will be peregrine chicks next year.
Hoping for happier times ahead.
UPDATE later on 14 May: Well, that didn’t take long! A new, banded FEMALE peregrine came to the nestbox on 14 May at 2:27 PM.
Here she is at the nest this afternoon. I thought this was Morela but when I looked at the image I can see that SHE’S BANDED! (Morela was unbanded.)

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.

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?

From Earth, Saturn is tiny and the Moon is large. You can see the huge size difference in Paul Byrne’s (@ThePlanetaryGuy) video of Saturn rising behind the Moon.

We’ve all experienced a moment when a smell suddenly brings back memories. A whiff of perfume, a hint of cinnamon and clove, even the smell of furniture polish can send us back in time with vivid detail.
The reason is that our olfactory bulb which processes smells is physically connected to the two places in our brain that process emotion and memory, the amygdala and hippocampus. The link makes a lot of sense in animals that use pheromones for sexual attraction.
This strange entanglement of emotions and scents may actually have a simple evolutionary explanation. The amygdala evolved from an area of the brain that was originally dedicated to detecting chemicals, Herz said. “Emotions tell us about approaching things and avoiding things, and that’s exactly what the sense of smell does too,” she said. “So, they’re both very intimately connected to our survival.” In fact, the way we use emotions to understand and respond to the world resembles how animals use their sense of smell.
Which brings me to this plant I found blooming at Hays Woods in late April. The scent of cypress spurge (Euphorbia cyparissias) is so unique that it takes me back to a particular place and time and the happiness of seeing beautiful birds at Presque Isle State Park in early May.

On Throw Back Thursday here’s why cypress spurge reminds me of migrating warblers:
