It’s back to Global Big Day with more bird pictures from Presque Isle State Park, mostly after the rain started.

It was a rather amazing Sunday at Presque Isle State Park – sunny, warm/humid, the smell of Multiflora Rose in the air, then ocean-like ground fog along the outer beach. Bird-wise, things got off to the best start possible for a hike out to Gull Point with exceedingly cute Killdeer chicks in the Budny Beach east parking lot:

Later, an amazing American White Pelican trio over outer Gull Point. (Ho-hum, just another day at the Point… 😉 Reported occasionally on eBird, still a rare occurrence for Erie County and the east coast generally – this is the first BirdingPI.com local sighting ever:

Here’s an alternating medley of more Killdeer and Pelican:

These Pelicans came in the from the west/northwest maybe, then made a looping turn over outer Gull Point to head pretty much due south:

Pure conjecture, but considering the abrupt turn south from the lake, wonder if they were using Gull Point as a navigation landmark. (“Bird things that make you go ‘hmmmm….'”)

Finally, same day at Gull Point, the perils of field mis-identification. Following bird spotted flying overhead – obvious shorebird, decent sized, with long straight-ish beak – immediate thought is Yellowlegs. “Why does that Yellowlegs have a rusty belly?” Good question. The answer: not a Yellowlegs, but an unusual-for-Presque Isle Hudsonian Godwit:

To be fair, hard to see well under these lighting conditions, but still a good example of being cognizant of field marking inconsistencies (e.g., no species of Yellowlegs has a streaked, rusty belly, regardless of age).

Well, Global Big Day weekend is long gone, and spring warbler migration is past-peak, but it was an oversized holiday weekend at Presque Isle State Park nevertheless. Compounded by rather amazing weather: a sunny Saturday start with rain by late morning (clearing later), a warm and humid Sunday w/ eventual ocean-like ground fog, & big afternoon thunderstorms Monday (including torrential rain & pea-size hail).

Concurrent with spring, of course it’s nesting season. Recent nests and/or chicks (juvenile birds) seen at Presque Isle: Bald Eagle, Osprey, Common Grackle, Red-winged Blackbird, Killdeer, American Robin, Wood Duck, Barn Swallow, & Tree Swallow. Here’s a great sequence of a lovely female Yellow Warbler nest building in a blackberry shrub along the Gull Point Trail, from Saturday (before the rain):

Coming up soon, amazing American White Pelicans at Presque Isle! Also, special Eastern Towhee portraiture! And baby Killdeer! #more_exclamation_points!!! #more_bird

“Dr. Science, I didn’t know there was a feral cat population in Presque Isle State Park!”

“Yes, Joey, there is. Although due to harsh winter conditions, ‘population’ more likely means transient individuals, such as strays wandering in over the ‘land bridge,’ or abandonments, or perhaps wide-ranging house cats from nearby neighborhoods.”

“Dr. Science, a ‘wide-ranging house cat from a nearby neighborhood’ wouldn’t be feral exactly, right?”

“You’re very astute, Joey. That means smart and observant. But take this example spotted recently by Dr. Science’s field team along the Duck Pond Trail. No houses around here!”

“That’s a beautiful cat, Dr. Science. It seems healthy.”

“Probably a reasonably steady diet of songbirds and chipmunks, Joey. House cats are great hunters.”

“Chipmunks!?! But they’re so cute, Dr. Science!”

“Probably also tasty, from a cat perspective, Joey.”

“Yuck. What’s going to happen to this cute kitty, Dr. Science?”

“No way to know, Joey – that’s nature for you. Hopefully it will wander back into inhabited areas, or be captured by the friendly park rangers for safe relocation to a good home.”

“Dr. Science, is the scientific name of the domestic house cat really ‘Felis Catus?’ That sounds made up.”

“Yes, it really is. … Say, Joey, have you ever been in a Turkish prison?”

So far this year there’s been Red-winged Blackbird harassing Red-tailed Hawk, Red-winged Blackbird harassing American Crow, Red-winged Blackbird and American Crow co-harassing Red-tailed Hawk, and Red-winged Blackbird harassing Canada Goose (<– true story; sadly, no pictures, but the goose seemed rather offended.) Here, it’s three Common Grackle and one Red-winged Blackbird harassing a Red-tailed Hawk, high above Erie County, PA:

First up, very special pictures of what may be the first ever BirdingPI.com coverage of Purple Finch in Erie County, PA! (Much less common than House Finch.) Taken recently at West Road Elk Creek access.

ID tip: typical finch features w/ an overall red-purple/raspberry wash.

Also exciting, amazing Purple Martin “in the wild.” Meaning not at or around a Purple Martin house. These pictures from the swampy area near the east Long Pond Trail trailhead.

Following are alternating Purple Finch & Purple Martin:

It wouldn’t be complete coverage without a comparison to House Finch. Following shots are of beautiful males in Millcreek Twp (“Gateway to Presque Isle”). Note the similar features but much less extensive red-purple colour:

Recent shots of male Red-winged Blackbird in flight in Erie County, PA, at West Road Elk Creek access. (More on this very interesting location coming up soon.)

Looks like nice weather Friday & Sunday, maybe rain Saturday. Happy birding/nature!

Warm temps and big thunderstorms yesterday and overnight in Erie County, PA. Weather this morning: sunny & plenty of bird activity. Time to get out into nature – just avoid the mud & wet grass!

Following, another lengthy posting of pleasant photos from the other morning at Presque Isle State Park, at Leo’s Landing:

Thank goodness – no crazy annotated photographs in today’s post. (Yikes.) Just pleasant bird photographs from Presque Isle State Park, taken a couple weeks ago (more or less) in the morning at Leo’s Landing.

[Editor’s note: the bird in the second photograph above appears to be a Bald Eagle, maybe.]

Time for recent long-distance observations at Gull Point. With a camera + long lens (most shots below @ 1200mm), lots of heat shimmer on a warm day = blurry birds. Nevertheless, a useful tool for interesting bird ID’s/sightings.

First up, terns! The most common tern @ Presque Isle State Park is Caspian Tern, the world’s largest tern species. Which is confusing, esp. for this post, because there’s a species actually called Common Tern. (Another awful/generic bird name.) And speaking of both, here’s a shot of mixed Caspian Tern, Common Tern, and what might be a juvenile Bonaparte’s Gull (?) on the lower right:

Let’s discuss this ID. Caspian Terns: relatively large, distinctive tern black cap, chunky/dagger-like red-orange bill. In the annotated shot below, Caspian Terns @ “A.” Best way to ID other tern species generally, if possible, is based on size. Note the terns at “B” – similar looking overall (black cap, pointy red or orange bill) but much smaller. Could be any of several smaller tern species, but at Presque Isle the non-rare options* would be Common Tern or Forster’s Tern. Meaning, start there for an ID analysis.

Both Common Tern and Forster’s Tern have a forked tail, so this shot is not terribly helpful:

OTOH, Common Tern typically has a gray belly and a thinner, reddish, black-tipped bill, whereas Forster’s = white belly and heavier, orange-ish, black-tipped bill.

In the annotated shot below, note what appears to be a gray belly at “A.” The bill at “B” appears orange-ish, but is very thin and straight:

Another factor: wing colouration. Common Tern has darker gray wings outlined by black at the tips, mostly visible in flight:

In this annotation, note the black-looking wing tip region at “A,” and again, the gray belly at “B:”

Another view of dark wing tips:

And another interesting clue, this time the bird @ lower right:

In the following annotation, note the colouration pointed to by the arrow. As per the experts, “Immatures and nonbreeding adults have a distinctive black bar on the leading edge of the wing, known as a carpal bar.”

So, very possibly an immature Common Tern. Another view:

In conclusion, small size, consistent bill, gray belly, dark wing tip regions, + possible juvenile = positive ID for Common Tern!

---

Moving on, a much easier ID of a blurry but still cute adult Piping Plover:

Note the single narrow breast band, thin black head band, and overall relatively light face/head colouration:

Semipalmated Plover (the next likeliest species at this location) would be overall larger, overall darker, & with a much darker overall face/head.

---

Another easier ID, it’s a blurry but great Black-bellied Plover:

Factors for this ID: relatively large, + black belly, + lacks the black top-of-head patch of an American Golden-Plover (which would be rare for this location/time anyway).

---

Enough long-distance, time for some ‘bonus’ not-as-blurry birds:

And as if this post isn’t long enough already, a great sequence of American Kestrel @ flying & landing:

This is one of the several Gull Point outwards-facing “Don’t moor within 100 yards of shore” (or something like that) warning signs for boaters, reflecting the protected nesting season status:

* Tip: to see the mostly likely candidates for the date/location in question, pull up the eBird checklist, which defaults to “non-rare.” For Gull Point in May, the most common tern options are Common, Forster’s, & Caspian. (Plenty of other ways to utilize eBird in this regard, such as looking at species reporting bar charts for recent years; here, 2023 reporting shows more reportings of Caspian and Common Terns in May, but fewer Forster’s.)

Coming soon, very blue and purple birds!
