Notes:

1.    Lesser Black-backed Gull numbers in the Kennessee and Ohio River Valley region continue to increase annually while numbers on the western Great Lakes appear to have decreased in recent winters. Noteworthy are reports of over 40 individuals from Benton County, Tennessee this month.
 
2.    California had no less than 10 reports of Lesser Black-backed this month, with roughly half of these coming from Monterey County and points north.
 
3. The Fairfield County, CT Kamchatka Gull and Bristol County, RI Common Gull went missing for most of the month, suggesting an observer bias, or these birds may in fact cover a rather large winter-feeding area. 

February 2023 Quiz

 

Oregon. January.

Age: The rather plain wing coverts and tertials, and adult-like gray scapulars suggest a 2nd cycle individual of a large, four-cycle species.

Identification: The blob-tipped bill and smudgy head immediately evoke thoughts of Glaucous-winged Gull and Western Gull. Overall the wing coverts and primaries seem a tad too dark for Glaucous-winged, and too pale for Western (especially the pale-edged primaries, for example). Given the location, it is reasonable to assign this individual to the Olympic Gull hybrid swarm. 

Several responses this month insisted on "pure" Glaucous-winged, reinforcing the subjectivity of identifying this species. Although it may be one, the primaries appear too dark to comfortably dismiss a hybrid.

31 January 2023

January 2023 Quiz

Florida. January.

Age:  A multi-bird quiz. Let's call these front, center and back. The center bird (facing right) seems to be the simplest -- an adult type hooded gull. The front bird is a smaller individual, but a member of the large white-headed gulls and should be a 1st cycle. The bird in the back is also a large white-headed gull, but clearly larger and suggests 2nd cycle. Why are these two white-headed gulls one cycle apart, given that they look somewhat similar? Three-cycle species mature faster, of course. Another way to say this is four-cycle species mature slowly.

Identification: Beginning with the center gull, the somewhat long and droopy black bill, medium gray upperparts, and much black in the wingtip, look spot on for Laughing. The smaller individual in the front has a small bill with pink base. The post-juvenile scapulars (1st alternate) are light gray. The size, in comparison to the Laughing Gull makes this a fairly safe 1st cycle Ring-billed. Ring-billeds often have messier wing coverts at this age, especially this late in the season, but some maintain plain coverts and dark tertials. The 2nd cycle in the back has kept much black on the bill and has obvious slate gray scapulars (2nd alternate). The body size and bill size seem to eliminate Great Black-backed. The only other expected dark-backed (so-called black-backed) species in Florida is Lesser Black-backed, which this is. 2nd cycle Lesser Black-backeds are highly variable. This one looks rather docile and still shows a largely dark eye.

Notes: 
1. On 10 December 2022, Andy Dettling found an adult Vega Gull in Wayne County, Michigan. This individual displayed all the field marks needed for this taxon, and would constitute a state first pending acceptance. Vega Gull is treated as a subspecies of Herring Gull by the AOS, but many bodies have now elevated it to species status.

 2. On 30 December 2022. Todd Eiben found an adult Common Gull in Cuyahoga County, Ohio. This individual shows intermediate features that are most consistent with Kamchatka Gull (L canus kamtschatschensis), albeit on the smaller end of the curve. The wingtip pattern is most interesting with a mix of features that combine canus, heinei and kamtschatschensis. It is doubtful that this bird will be confidently identified to subspecies.

December 2022 Quiz

 

Illinois. November.

Age: The nondescript brown plumage gives every indication of a 1st cycle large gull. In fact, all scapulars, upperwing coverts and tertials are juvenile (1st basic).

Identification: An interesting combination of uniform brown upperparts with neat pale edging throughout can match a number of species in November. But not many combine smooth brown neck, breast and sides, with paling bill. This individual superficially recalls Lesser Black-backed Gull, but that taxon generally lacks a pale bill base at this date, seldom shows pale tips on the primaries and has paler underparts. Our November quiz bird is "just" an American Herring in crisp juvenile plumage.

Notes:

  1. Perhaps most interesting this month is what proved to be 2 different adult Slaty-backed Gulls at the Muskegon Wastewater Treatment Plant in Muskegon, Michigan. While observers sensed there was something not quite right about the movement of black-backed gulls they were seeing in the area, no one explicitly picked up on two different birds in the field. It was Liam Singh who keenly discovered this multiplicity while reviewing photos on eBird. Differences in wingtip pattern and head pattern leave no doubt. This is the first time more than one Slaty-backed Gull has been present at the same site in the interior, and perhaps for all of the lower 48.
