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.

November 2022 Quiz

 

February. Indiana.

Age: A large gull with black upperparts immediately narrows down our options to a four-cycle species. Given the adult-like white tips to the flight feathers, with brown markings on the underwing coverts and marked tail, we can be sure this isn't an adult, and best fits a 3rd cycle type.

Identification: Black-backed adults in North America can be approached by leg color, size/structure and wingtip pattern. The massive bill and head, all white tip to p10 (left wing) and pinkish legs point directly to Great Black-backed. Lesser Black-backed is ruled out by overall structure and wingtip pattern (note, some Lessers can show fleshy legs at this age). Western (and Yellow-footed) is ruled out by the white tip to p10. Slaty-backed Gull doesn't typically show this massive bill with large blocky head, and should have broader white tips to the trailing edge. Our November Quiz bird is indeed a 3rd cycle type Great Black-backed.

Notes:
1. Approximately 10,000 Black-legged Kittiwakes were recorded migrating west from Point Barrow on 11 October 2022. These numbers are not typical here, to say the least. See Alex Lamoreaux's report for details. 16 juvenile Thayer's Gulls were also reported. In most years 1-2 may be reported here at the height of Fall migration.

2. A nice showing of 630 Ross's Gulls was recorded at Point Barrow on 16 October 2022.
