Black-capped Chickadees vs. Carolina Chickadee Here is the chickadee information I have written up for the CBC folks. From Jodi’s ebird pics the wing markings look good for a BCCH but I would like to see the full side view of the cheek. Black-capped Chickadees vs. Carolina Chickadee Black-capped Chickadees only occur in the Shenandoah Valley in the winter (late Oct to April) although there is a subspecies that breeds and winters in the Appalachian highlands – Highland County is a good spot. Even in invasion years BCCH tend to be rare to uncommon east of the Blue Ridge Mountains. Our lowland summer chickadees are Carolina Chickadees. Some winters northern “Canadian” chickadees migrate south and some winters they stay put in Canada, like the events that occur with northern winter finches (Pine Siskin, Redpolls, Evening Grosbeaks, Purple Finches, Crossbills, Pine Grosbeaks). The winter of (2016/2017) we had a good number of Black-capped Chickadees in the Shenandoah valley (40 to 95 % BCCH at feeders) whereas winter 2017/2018 and 2018/2019 we had none. This winter 2020/2021 we have a moderate number of BCCH in the Shenandoah Valley with most feeders having 1 or 2 to each 10 to 20 CACH. Here is what to look for. The BCCH white cheek is slighter darker under the eye then very white as it approaches the nape and large (each side almost touches) and has a fairly distinct border with the gray back. CACH is whitest under the eye then gets grayer as it approaches the nape and blends into the back. I have not seen this in textbooks but is a very good consistent feature to separate the two species. BCCH has the primaries and wing coverts white edged making it look like a hockey stick on the wing (hockey fits in with the more northern Canadian BCCHs). The CACH has the primaries light gray or light whitish edged but the wing coverts are not contrastingly edged – no blade of a hockey stick. BCCH has the tail feathers extensively edged white, extending down the feather. CACH has only whitish or gray edged tail feathers, mostly restricted to the tip (distal) of the feather. BCCH has a more extensive somewhat ragged black bib (the feathers are ½ black and ½ white at the junction to give the ragged effect often with errant black feathers below the bib demarcation line.). CACH has a small very sharply edged neat looking bib. The overall effect for BCCH is a very contrasty brighter, slightly larger bird. Once you get the marks down they are identifiable even in flight. Black-capped Chickadees have a lower slower “chick a dee dee” song than the CACH but this takes some experience for some people. Black-capped Chickadees are larger, but it takes some people a little practice to evaluate that. When banding them we take a wing measure and tail measure and plug it into a chart that gives a species determination. The BCCH has the larger measurements. Frankly once you get to see a few BCCH the measurements are not needed. I have trained 6- and 7-year-olds to identify them with 100% accuracy. My students who were lucky enough to help me band in a BCCH invasion year, quickly got to the point of being able to identify the species accurately, even while they were still in the net. If anyone wants me to check out a jpeg please send the image to <rsimpson...> or <rob...> Send different angles if possible but try for a side view with even overcast light for an easy identification. Shoot me some more photos if you think you have BCCH. See our http://www.agpix.com/snphotos and type in chickadee to see the 2 species taken at the same perch under the same lighting conditions – this is from our 2016 major invasion of BCCH.

OCEAN CITY, CHINCOTEAGUE, CAPE CHARLES, December 27-31, 2020 & January 1, 2021. A trip with George in his Nissan. 3 Christmas Bird Counts.
ABBREVIATIONS: cormorant = double-crested cormorant. ESVNWR, Eastern Shore of Virginia National Wildlife Refuge. KSP, Kiptopeke State Park.
DECEMBER 27, SUNDAY. S of Dover, DE, somewhere, c. 3,000 snow geese. On the way S from Philadelphia c. 12 red-tailed hawks and 2 Cooper’s hawks. Otherwise, at Ocean City:
common eider c. 30, king eider 1 imm. male (pointed out by Kevin Graff), American oystercatcher 17, dunlin 95, common loon 6, red-throated loon 6, brant 225, tundra swan 6 (WOC pond), sharp-shinned hawk 1, Forster’s tern 30, Bonaparte’s gull 3, long-tailed duck 14, red-breasted merganser 10, rock pigeon 135, bufflehead 30, sanderling 2, cormorant 35, Canada goose 40, ring-billed gull 300, great blue heron 5, hooded merganser 2, pied-billed grebe 2, American coot 12, a few black and surf scoters, black-bellied plover 2, northern gannet 0.
The West Ocean City Pond as barren as I’ve ever seen it. Spent most of the time at the inlet. Things a bit sparse there, too. Tonight and tomorrow night at Comfort Inn. $50/night I assume COVID-19 rates, unbelievably cheap … almost.
Common Eiders seem to be taking over the World. I’d heard up to 70 at Ocean City. On Jan. 3, 2021, George estimated 280 at Manasquan Inlet, NJ. For several years they’ve been breeding in eastern Long Island.
DECEMBER 28, MONDAY. Ocean City, MD, Christmas count. George and I work Center, the sector leader Lynn Davidson, accompanied by Hal Wierenga. Here are some of the birds George and I encounter, based largely on his eBird reports. Areas we hit, all south of Route 50: OC airport, Castaways Campground, the Walmart Pond, Jerry Mack Rd., and Seahawk Rd. We join Lynn & Hal for an hour at Castaways in mid-afternoon, when it is low tide. There are plenty of shorebirds:
brant 60, Canada goose 770, gadwall 6, American black duck 160 (in an inland plowed field !!), ring-necked duck 23, bufflehead 44, common goldeneye 2, hooded merganser 25, red-breasted merganser 25, green heron 1 (seen by George & photographed several times, at the golf course), bald eagle 6 (in sight simultaneously: a pair eating a horned grebe, a 3rd on a piling nearby, that drops down to catch a small c. 6” fish, a 4th perched on the roof of one of the many dozen cabins at Castaways),
These are unofficial, incomplete, totals. Earlier in the day Lynn and Hal see a yellow-throated warbler. Haven’t heard what else they see. Early in the day, when the tide is up, I carefully estimate 620 dunlin, counting by tens. George knows this sector well - all the little lakes, the fields, woods, and small roads - having covered it for years.
With my bad right leg I spend a couple of hours just sitting and scanning at Castaways, and at the productive Walmart Pond (where I get the shivers), most of the rest in or close to the Nissan.
Fair or partly overcast, 41-55 (but with a chilly SW15 wind), 7:15-5. 7 deer, 1 gray squirrel.
DECEMBER 29, TUESDAY. Chincoteague N.W.R. Christmas count, the refuge Wash Flats Road, George, Bill Hohenstein, and me. Totals below are incomplete, a combination of eBird reports by George and Bill and my own observations. George and I are only there until 12:30, Bill all day.
sora 2 (BH,GA; present earlier). common gallinule 2 (seen by all of us). waterfowl dominate, as expected: snow goose 280, tundra swan 13, gadwall 600, American wigeon 7 (think I heard 4 males were present earlier), American black duck 225, mallard 55, northern shoveler 250, northern pintail 210, green-winged teal 110, bufflehead 220 (big flocks of almost entirely female-plumaged birds inside the impoundments). I feel some of these totals are low.
Otherwise: great egret 12, tricolored heron 1, white ibis 4 (lots more seen along Wildlife Drive), bald eagle 11, peregrine falcon 1, dunlin 200, American woodcock 1 (BH), Bonaparte’s gull 1, Forster’s tern 7, great horned owl 2 (BH), Carolina chickadee 11, brown-headed nuthatch 9, marsh wren 1 (BH), hermit thrush 3, orange-crowned warbler 2, myrtle warbler 435 (many observers, in my opinion, tend to overestimate how many there are; but surely there’s a bushel basket or 2 of them present, no doubt), swamp sparrow 15, brown-headed cowbird 1 (with big flock of starlings apparently consorting with ponies).
Also: fox squirrel 3 (1 by BH, 1 seen by GLA & HTA, a 3rd heard by GLA). sika deer 1. c. 36 ponies. clear, 31-41, winds NW 10-20. pretty day.
DECEMBER 30, WEDNESDAY. Cape Charles Christmas count, ESVNWR area. 7-6, clear, SW10 - calm - SW15-20, temperatures 25-50, tide high A.M., low P.M., both times more extreme than usual (full moon Dec. 29). 56 species, Kristin Klein, Liz Armistead, and me. Highlights, such as they are:
snow goose 300, bufflehead 70, hooded merganser 8, wild turkey 30, common loon 1 (loons and grebes scarce hereabouts), brown pelican 9, cormorant 110, tricolored heron 1, bald eagle 9 (2 active nests are in the area), red-shouldered hawk 2, merlin 1, killdeer 33, American woodcock 48 (mostly seen by others at dusk after they had finished covering their assigned areas), great horned owl 1 (Dan Cristol), northern flicker 6, crow unIDd 65, eastern bluebird 16, hermit thrush 2, myrtle warbler 110, palm warbler 2, common grackle 150, purple finch 1.
2 other all-day parties cover different parts of this sector with our combined species total 106, reported previously at length on VA-BIRD. Also, we see 6 white-tailed deer.
Most of us stay in the no. 5 lodge of Kiptopeke State Park. Rudy Cashwell brings us a BIG sack of clams he has raised and some beautiful vegetables, which, if Cezanne had seen these first, would have caused him to abandon his apples, oranges, and other fruit. They’re THAT pretty.
Today George works the big Ferry sector, as he has for several years, that extends from the north side of Route 704 KSP for 5 mi. or so north, all of it west of Route 13. His very successful day with 86 species include a black-and-white warbler, 5 orange-crowned warblers, 190 cormorants, 2 blue-headed vireos, 162 brown pelicans (on the concrete ships), 13 bald eagles, a peregrine falcon, 28 ruby-crowned kinglets, 5 white-breasted nuthatches, 33 red-breasted nuthatches, and 26 vesper sparrows.
Some recent years there’ve been only 1 or just a few vespers here. In big decline as with so many others grassland birds. I remember one year back a ways when we had more vespers than juncos. Imagine that!
DECEMBER 31, THURSDAY. After 4 days of sun and moderate temperatures today is overcast with light rain or mist off and on, but the temperature gets up to 50. Something of a relief NOT to have to press hard on a Christmas count today. The pressure’s off. Good to sleep in a little. I see 75 brown pelicans on the concrete ships.
At Ramp Lane early, hooded merganser 5, tricolored heron 1, red-breasted merganser 1, bufflehead 7, great blue heron 1. 48, overcast, S15, light rain. Derek Ayres, George and I go along Arlington and Custis Roads late morning to early afternoon: GOOD look at an orange-crowned warbler, wild turkey 3, red-tailed hawk 3, yellow-bellied sapsucker 1, American kestrel 2, red-shouldered hawk 2, fox sparrow 1, hermit thrush 1, bald eagle 2, 100s of Canada geese, American oystercatcher 1, American crow 45, and 13 deer.
Ramp Lane, again: 4:30-5:30, 53-55, light rain, overcast, NW5+: bald eagle 1, bufflehead 12, hooded merganser 34, red-breasted merganser 2, and 4 deer . On the way back to the lodge after rampin’ it up, see an eastern cottontail and a small frog leaping, saltatin’, across the wet, warm road, I bet either spring peeper or green tree frog. Rushing the season, little fella?
JANUARY 1, FRIDAY. There is a Long-bodied Cellar Spider on the wall of our rest room, identified by George via iNaturalist. He counts 140 brown pelicans at the KSP concrete ships, earlier had a fox sparrow, a bald eagle, and a woodcock from his room at KSP lodge no. 5. He and Kristin see 28 vesper sparrows, Arlington Road, no doubt the same group he saw yesterday.
With Liz Armistead on the way home to Philadelphia: MACHIPONGO - BOX TREE ROAD: 10:53 A.M., 43, overcast, calm, tide starting to let out: greater yellowlegs 35, dunlin 110, kingfisher 2, black duck 6. WILLIS WHARF, tide real high: ruddy turnstone 4, herring gull 60 (on Terry’s roof), bufflehead 11, hooded merganser 2, common loon 1, gray squirrel 1. On leaving, run into Gerry Tracy and his lady friend.
Best to all. - Harry Armistead.

I think maybe it's not mentioned much is that it's hard to tell the difference in size unless you have both species at the same time,then it's quite obvious. BCs seem to have a bigger head in proportion to their bodies that does the Carolina. Anita

I find the size difference to be quite obvious, even without a direct comparison. Perhaps that comes from so many years of observing these birds.Â And the Black-capped is always verifiable by its much slower and deeper-pitched "chick-a-dee-dee-dee".Â Thanks for writing, Anita.Â Sincerely,MarleneÂ In a message dated 1/9/2021 2:00:54 PM US Eastern Standard Time, <aghuffman...> writes:Â I think maybe it's not mentioned much is that it's hard to tell the difference in size unless you have both species at the same time,then it's quite obvious.

Thanks everyone. My friend and I got a glimpse of it today before she flew off. We waited for nearly two hours and she didn't return so we left. We've photographed her twice there but were hoping to get better photos. Oh well. Vineeta "Choose to be optimistic. It feels better.â€ Dalai Lama XIV
