Derek’s Birding This Week, 4/17-23/2021

My Leica V-Lux camera went to the doctor, and it finally arrived after about two months. This Snowy Owl on our first Saturday Morning Birdwalk of the year was a great way to break it back in!

My highlights over the past seven days included the following:

  • 1 continuing immature SNOWY OWL, Pennell Way, Brunswick, 4/17 (with Saturday Morning Birdwalk group).
  • 2 Evening Grosbeaks, Florida Lake Park, Freeport, 4/21.
  • Big push of White-throated Sparrows overnight 4/20-21 and perhaps another push later in the week. High count of 75+ at Capisic Pond Park and 100++ at Evergreen Cemetery (both 4/23 with client from Maine).
  • 1-2 Evening Grosbeaks, our yard in Pownal, 4/23.
  • 1 Peregrine Falcon and 1 Fish Crow, Capisic Pond Park, Portland, 4/23 (with client from Maine).

And my personal first-of-years and new spring arrivals this week were limited to just:

  • 1 Barn Swallow, Florida Lake Park, Freeport, 4/20.
  • 1 Blue-headed Vireo, Florida Lake Park, 4/21.

On Tuesday  – our biggest flight of the season at the Bradbury Mountain Hawkwatch – we observed an extremely pale Red-tailed Hawk. I propose it as a “Krider’s” x “Eastern” Red-tailed Hawk. Here’s my short blog about it:

And don’t forget about Feathers Over Freeport this weekend! Self-guided walks for kids, take-home crafts, and live online programs featuring live birds of prey. Saturday’s keynote address “Digi-scoping Made Easy” by Jeff Bouton on Kowa Sporting Optics.  We arranged for this based on the frequency of questions we get asked here at the store about taking photos through a spotting scope using a digital camera or a smartphone. It’s free, but pre-registration is require

Possible “Krider’s” x “Eastern” Red-tailed Hawk, Pownal, Maine, 4/20/21

This stunningly pale immature Red-tailed Hawk passed over the Bradbury Mountain Spring Hawkwatch, sponsored by Freeport Wild Bird Supply, in Pownal, Maine on the afternoon of April 20, 2021.

Highly suggestive of the extremely pale “Krider’s” Red-tailed Hawk (a subspecies or quite possibly just a very pale color morph) from Central North America and with scattered vagrant records along the Eastern seaboard, we believe this individual shows features most consistent with an “intergrade” between the so-called Krider’s and our typical Eastern subspecies.

The very pale white head first brought my attention to this bird as it approached the summit from the north-northeast, and circled overhead and slightly behind the plethora of counters and observers on our biggest flight day of the season. Tova Mellen gets the award for the best photos – by far – and we appreciate her effort and willingness to share them. Thanks, Tova!

Andrew Sharp, Mathew Gilbert, and Charles Duncan also managed photos, and I was able to capture (poorly!) a few additional angles that show some helpful features.

The mostly-white head, very pale underparts, and lightly-marked underwings (especially the reduced patagium) all suggest Krider’s. However, the darker crown and fairly-dark spots on what would be the edges of the belly band are more suggestive of an intergrade.

The relatively bold white panel on the upperwings is also suggestive of Krider’s, but it’s not as bold and bright as many photos suggest. The back color is also brownish-gray. Both of these look to be more consistent with an intergrade.

The white uppertail coverts/lower rump area was more evident than this too-dark photo suggests, nonetheless, it does not seem white and broad enough to be a Krider’s. Unfortunately, the pattern of the uppertail was not decipherable.

The poor exposure of this photo makes the bird look much darker than it appeared in the field (looked more like Tova’s photos, above), but it does accentuate where the dark markings are and are not.

As for printed references, this bird looks to be a near-perfect match for the “Juv/1st Year Eastern x Krider’s Integrade on Page 66 of The Crossley ID Guide to Raptors.

We had limited views of the upperparts, but they did suggest the presence of fairly extensive white on the scapulars, the large pale window, and the narrow pale uppertail covert band as shown on page 293 of Raptors of Eastern North America by Brian K. Wheeler.

Therefore, we reached the tentative conclusion that this bird was an Eastern x Krider’s, but as with all subspecies and especially hybrid thereof, designations of Red-tailed Hawk, absolute identification is likely impossible. Fun bird though!

I’ll add any comments and feedback I receive here:

A Mid-Western Road Trip

When the Iowa Ornithologists’ Union invited me out to be the Keynote Speaker for their 2013 Fall Meeting, I jumped at the opportunity to get some birding in in a part of the country that I have not spent very much time exploring.  Add to that a program and book signing at Milwaukee’s Urban Ecology Center, and I had a solid excuse to work on some under-served state lists…and visit some good friends.  Each day, I posted a short synopsis of my travels and birding on my book’s Facebook page.  Here, I’ve simply edited those and added some photos for your viewing pleasure.

10/10: Travel to Des Moines, Iowa.  Departing Portland at 6:14am.

10/11: Ankeny, Iowa.
On my way to the Iowa Ornithologists’ Union‘s Fall Meeting, I spent the first day and a half of my trip birding the Des Moines-Ankeny area with my friend Danny Akers, the 2009 Bradbury Mountain Spring Hawkwatch Official Counter.

I had hoped for Smith’s Longspurs to fill in a gap on the ol’ life list, but unfortunately, we came up empty, despite a few miles of walking up and down short-cut fields at a couple of locations. While a stiff southerly wind has not helped, they just don’t seem to be “in” yet. Unseasonably warm temperatures – a high of 78 yesterday for example – has likely put quite a few fall arrivals behind schedule.

A nice consolation prize for me, however, was a fair number of LeConte’s Sparrows – a bird I really like, but don’t get to see too often. Other birds that were a treat for me include Franklin’s Gull, Sedge Wren, Red-headed Woodpecker, and American White Pelican. Our best bird, however, was probably the Pileated Woodpecker at Waterworks Park in Des Moines – a long overdue Polk County bird for Danny.

But as always, I just flat out enjoy birding new places. And since I’ve only barely birded Iowa once before, my state list is growing by leaps and bounds. I was not too happy that I was unable to bird the famous Saylorville Reservoir, however, thanks to the government shutdown. John Boehner: you owe me some state birds!

We then headed east towards Clinton, where Danny and I would be leading a field the next morning.  I very much looked forward to seeing what might be moving behind this approaching cold front. While it might not clear in time for a flight tonight, Sunday morning could be a lot of fun.

10/12: Clinton, Iowa – Iowa Ornithologists’ Union Fall Meeting.
Danny and I led a field trip this morning to Princeton Marsh here in Clinton, IA. We had a great turnout – I was honored! – of birders. I just wish there were more birds than mosquitoes!

Few migrants were around in the morning; there was no morning re-determined migration today. The approaching cold front took its sweet time in getting here, and had not pushed through easternmost Iowa by dawn. It was interesting to see the huge flight on the Des Moines radar overnight, just west of the front, compared to the Davenport radar, just east of the front (where we were).

So the woods were quiet, but we had ample numbers of things like Yellow-rumped Warblers, both kinglets, and lots of Red-winged Blackbirds commuting overhead. A heard-only Pileated Woodpecker and a good look at a Winter Wren were local highlights. Oh, and I got a life frog: Cricket Frog! And lots of Leopard Frogs were around; it was not a good sign that I was ranting about bush honeysuckle and playing with frogs within the first 30 minutes of the walk.

A scrubby, weedy wetland area near the southern edge of the property was much birdier, however, highlighted by a teed-up LeConte’s Sparrow, 7 Wilson’s Snipe, and a Sora. A small group of 5 Eurasian Tree Sparrows were a little unexpected.

The front had now pushed through, dropping just a few sprinkles, but also blowing away the skeeters. That was nice. Danny and I decided to try a little river migration watching, so we headed over to a small riverfront park in Princeton that intrigued us during a quick visit yesterday.

Now we were in business! A trickle of raptors began to move overhead, as soon as the clouds cleared. A handful of Sharp-shinned Hawks, a Merlin, a few Red-tails, etc. A group of about 30 Franklin’s Gulls sitting on the sandbar took flight, soaring high and perhaps southwards. As we were about to depart, a line of 32 American White Pelicans came cruising down the river. Yay, migration in action!

In the afternoon, I presented my Russian Far East: In Search of the Spoon-billed Sandpiper program. Yeah, I apologize I went a little long there. Oops. But it was such a great experience to share, and really, is there ever such thing as too many Tufted Puffin pictures?

10/13: Clinton, Iowa.
What a difference a day makes! A very strong flight took place overnight Saturday into Sunday, and a lot of birds arrived for Sunday morning.

Not only was I very happy to see a lot of birds on our field trip to Princeton Marsh, but I was happy to see that my predictions came to fruition. Following my evening program “A Sandy Point Case Study,” in which I concluded with a little local radar analysis, I predicted it was going to be a good morning (it’s always a risk sticking one’s neck out like that!).  And it certainly was at Princeton Marsh at least!

Large numbers of Yellow-rumped Warblers were reorienting overhead at dawn, and new arrivals included Palm Warblers and Fox Sparrow. Some waterfowl also arrived with Blue-winged and Green-winged Teals, and Gadwall becoming new entries in my state list. 2 Nelson’s Sparrows joined two LeConte’s Sparrows; both species were seen very well by all, and Nelson’s is fairly rare around here.

Very local in Iowa, a conspicuous Pileated Woodpecker was enjoyed (a lifer for some, actually), as was a spiffy adult Red-shouldered Hawk. But the bird-of-the-day was a very truant adult White-faced Ibis that was foraging in a shallow wetland.

A great morning of birding concluded a most enjoyable and productive weekend for me. I thank the Iowa Ornithologists’ Union for having me out, and I hope to see you again soon!

10/14: Clinton, Iowa:
Danny and I headed north this morning. Our first stop was the Goose Lake WMA.

After another good flight on the radar overnight, we found a lot of birds here. American Robins, White-throated and Swamp Sparrows, Red-winged Blackbirds, Cedar Waxwings, and Song Sparrows were all abundant, trumped only by the cloud of 500+ Tree Swallows.

A flock of Rusty Blackbirds were in the marsh, along with a single Ring-necked Duck – the last two new species for my Iowa list of the trip. The highlight for me, however, was the 60+ Wilson’s Snipe that joined ~25 Killdeer on a mudflat in the marsh; I’m not used to seeing so many snipe together.

We then drove to Madison, Wisconsin, picked up David La Puma and new friend Jessica Gorzo, and – in what, in hindsight was not a great idea – raced north to chase a long-staying White-tailed Kite. Not that an occasional chase with friends is a bad idea, but the fact that we were essentially racing the sun made us reconsider this.

Arriving in the area with about 30 minutes to sunset didn’t provide much hope, but an ultra-distant male Northern Harrier hovering over a field did – at least for a little while. Flocks of Sandhill Cranes were heading to roost, as was a massive cloud of Canada Geese. No small – in my mind – consolation prize, however, was the flock of about 30 Greater Prairie-Chickens that I spotted as they flew just over the tops of a field, before disappearing into the grass. Although known to be here – and intensively managed for them – they are not often seen, especially at this season, so that was a real treat for me. Having seen Greater Prairie-Chicken many fewer times than White-tailed Kite, I left satisfied. Mostly.

Danny said goodbye and took off in pursuit of the White-tailed Kite once again (unfortunately, despite many people looking it was not seen, and has never been seen again. Apparently, we missed it for good by exactly one hour). David and I wished him luck, but we thought our time would be better spent birding locally in Madison before heading over to Milwaukee.

The Pheasant Branch Conservancy was our destination – after a ridiculously late start for all (our respective travels had clearly caught up with all of us!). While the radar did not suggest that this was a morning that could not be missed, we probably – it’s October afterall – should have motivated sooner, but sometimes the body makes such decisions for you.

However, even in the middle of the morning, this Middleton preserve was decidedly birdy! It was full of sparrows, and my paltry state list grew by leaps and bounds. Fox Sparrows had arrived, White-crowned Sparrows were in good numbers, and plenty of White-throated and Song Sparrows were to be found, along with a goodly number of Lincoln’s Sparrows – one of my favorites!

Before we knew it, however, it was time to head to the Urban Ecology Center for my evening program. At a pre-presentation dinner, it was great to meet some new friends, and get re-acquainted with some of the people who joined me (OK, technically, I joined them) aboard the UEC’s private charter aboard the Schooner Lewis R. French out of Camden, ME last summer. They were stuck with me for 5 days yet came back to hear me talk even more, so I guess that is a good sign!

I wanted to thank Tim Vargo of the Urban Ecology Center for inviting me over, and I thank everyone who came out last night. I hope you all enjoyed the show!

Following my Sandy Point Case Study presentation at the IOU Meeting over the weekend, I looked at the local radar with the group and suggested it would be a very good morning in the field. And, in most places, it definitely was. After my Urban Ecology Center program last night, we looked at the radar and saw virtually nothing that suggested bird migration.

David chastised me a little bit for even hinting that “no migration on the radar” means “don’t go birding in the morning.” “It’s migration – go birding every morning!” (My point in the progrAm was simply that I would not have gone to Sandy Point that next morning). And he’s absolutely right. There are plenty of birds around in mid-October even when they have not moved in the night before.

While there might not be a Morning Flight of note without many “new” birds, there are plenty of birds in the field – literally. It’s sparrow season, and just to prove the point, local Madison birding once again proved why you go birding every day in migration! First, we walked through the woods from David’s neighborhood to the 1918 Marsh. Not much happening. A walk around and through the marsh, out to Picnic Point. A little dissapointed by the low numbers of sparrows, we instead enjoyed a nice little sampling of newly-returned migrant waterfowl (Northern Pintail, Bufflehead, Gadwall, American Wigeons, and Redhead), and lots of American Coots. Coots always amuse me. And drake Wood Ducks are always worth and extended view.

Readers of my blog and the store’s Facebook Page know I am a big fan of birding community gardens in the fall, so you could image my glee when we exited the Biocore Prairie (which itself had a goodly number of sparrows) and I stepped into the acres of the Eagle Heights Community Garden. This is where all of the sparrows were! 400+ House Sparrows, 150+ American Goldfinches, 100+ White-throated Sparrows, 75+ Song Sparrows, 50+ White-crowned Sparrows including one of the western subspecies Gambelli. A couple of dozen Lincoln’s Sparrows and Dark-eyed Juncos. A smattering of Field Sparrows, Yellow-rumped Warblers, and Chipping Sparrows. A handful of Palm and Orange-crowned Warblers, 1-2 Fox Sparrows, and my 100th Wisconsin Bird: 2 Brown-headed Cowbirds. Times flies (as in almost 3hrs here!) when you are having fun!

This was my last day of birding of my little Midwest trip. After David and I hit the Eagle Heights Community Garden in Madison (more juncos and Chipping Sparrows, 1 Nashville Warbler, multiple Orange-crowned Warblers, a late Ruby-throated Hummingbird, a continuing “Gambell’s” White-crowned Sparrows, etc), I hit the road for Minneapolis.

Visiting a non-birding friend – yeah, sometimes I tolerate hanging out with people that don’t like birding – my birding was limited to a walk around LoringPark and the art museum’s SculptureGarden. White-throated Sparrows were quite common, with a fair number of Dark-eyed Juncos, Swamp Sparrows, and a couple of Lincoln’s Sparrows. There was actually a reasonable diverse selection of migrants in this small, very manicured city park. And I do love city park birding!

As much as I love to travel, I love to come home even more! It’s good to be back, but I thoroughly enjoyed my time birding, visiting, and chatting about “How to Be a Better Birder” in Iowa and Wisconsin. Thanks again to the Iowa Ornithologists’ Union, Tim Vargo at the UrbanEcologyCenter, Danny Akers, and David La Puma for making this tour happen.

Next up, New Hampshire Audubon in Concord on 10/24.
