November 2023 Quiz

 

March. Illinois.

Age: The marbled greater coverts, overall muted pattern to the upperparts, and rounded primary tips suggest a delayed 2nd cycle type. Our November bird is a four-cycle species, and the upper mantle shows some subtle, adult-like gray, which also points away from a 1st cycle.

Identification: The fairly straight and short bill, small rounded-head, low-contrast upperparts and brownish primaries with pale edging are all fairly typical of a 2nd cycle Thayer's Gull. For comparison, a 2nd cycle American Herring is in the background, showing a messier appearance with high contrast from the primaries to the tertials, and tertials to the wing coverts. Our November Quiz gull is a small, female type, Thayer's Gull.

Notes:

*The 1st ABA Gray Gull from Walton County, Florida was last seen on 15 November 2023, but was later spotted by Don Clark from the Dauphin Island-Fort Morgan Ferry in Baldwin County, Alabama on 27 November 2023. Attempts to relocate this Albama 1st State Record were unsuccessful. Interestingly, this individual performed a similar jaunt in late September where it was relocated 40-50 miles to the west in Pensacola Beach. It would behoove observers from the Walton County, Florida region to continue searching for the Gray Gull at Dune Allen Beach.

October 2023 Quiz

 

September. California. 

Age: The overall fresh patterned coverts, mottled head and body, black primaries and dark tail suggest a 1st cycle.

Identification: Given the location, Western, Herring and California Gull are in the running. Several features support California Gull, including the small head, fairly straight bill that is already almost completely pale in September, as well as the long wing projection. The extensive white areas to the greater coverts are unexpected in American Herring. Western Gull is ruled out by bill size and overall structure. Also note the plain post-juvenile scapulars, which are common in California Gull, but usually dark-centered in Western. 

The October Quiz bird is a relatively large (m?) 1st cycle California Gull.

Notes:

  • The Florida Gray Gull was reported throughout the month in Walton County, but it's obvious the bird moves to unknown locations at times where it goes unnoticed. Most secondaries are now replaced, revealing a rather broad white trailing edge consistent with 2nd/3rd basic feathers. Given the earlier images from June 2023, the most likely explanation is the bird is now in 3rd basic.  
  • Nick Ramsey reports Chandeleur Gulls (presumed hybrid Kelp x Herrings from the Chandeleur Islands off the coast of Louisiana) were present on the islands on 30 October 2023. According to Donna Dittmann, this is a departure from years past where these hybrids would leave the area after breeding. 
  • Lesser Black-backed Gull continues to expand its nonbreeding range in the interior. At Findlay Reservoir in Hancock County, Ohio, Edward Hicks recorded no less than 438 individuals, which is likely an undercount of birds arriving to roost at dusk. This serves as a new interior high count for North America, away from the Atlantic.

    The October 2023 eBird map shows an obvious incursion north, as far as southern Alberta (~ 4) and British Columbia, and as far west as Tillamook County, Oregon and Humboldt County, California on the Pacific. The number of singletons reported west of the Rockies is simply awesome. Finally, sightings from southern Baffin Island around Iqaluit have increased in the last 2-3 years, likely due to increased coverage.

September 2023 Quiz

 

Wisconsin. May. 

Age: Our quiz bird is in the center of the frame, in flight. The full tailband and dark ulnar bar across the upperwing suggest a 1st cycle. Given the month, it would be a one-year old, but it still hasn't begun its 2nd prebasic molt as all of the primaries are still intact. 

Identification: The trailing edge to the wing is important, and helps rule out Bonaparte's & Black-headed Gull. There is a trace of dusky pigment across the trailing edge of the outer secondaries and inner primaries, which rules out Black-legged Kittiwake. Given how bold and full the ulnar bar is (for a one-year old), the small bill and dusky cap, it is safe to say that the September Quiz bird is a Little Gull. The two-toned outer primaries (dark outer webs and paler inner webs) also support this ID. 1st cycle Little Gulls show pale wing linings, unlike older individuals which are marked boldly black. The even central tail feathers and full tail band rest any worries of a Ross's Gull. All the surrounding gulls are similar-aged Bonaparte's Gulls.

Notes:

*A tattered 1st ABA Gray Gull was found in Walton County, Florida on 03 September 2023 by Adam Pickos. The bird was associating with Laughing Gulls in and around Dune Allen Beach and continued/s to be seen through mid-day, Wednesday, 20 September 2023. After rumors of local residents having seen the bird since at least late June/early July began to circulate, photos of presumably the same gull at nearby Camp Helen State Park were shared (Marvin Bojo Friel; 05 June 2023). June photos show an individual with thin white tips to the secondaries and a grayish-white head pattern. The best explanation for the June plumage is 2nd alternate (2nd cycles averages thinner white tips to the secondaries and browner upperparts and outer primaries than adults). Between early June and early September, the tips to the secondaries became so worn, presumably, such that most traces of white were erased, now giving the impression of an individual undergoing its 2nd prebasic molt, especially given its transformed basic head pattern. The June photos, coupled with new flight feathers growing in September suggest the bird was actually undergoing its 3rd prebasic molt (and hence a 3rd cycle). At the conclusion of its current prebasic molt, this individual should be virtually indistinguishable from an adult, and in fact would simply be labeled an adult. After going missing for a couple of days, it was relocated about 40 miles to the west in the Pensecola Beach region on both 24-25 September 2023. It then returned to its original location at Dune Allen Beach on 29-30 September 2023.

Relevant to this month's highlight, Liam Ragan found Mexico's 3rd Gray Gull (alternate adult) at the mouth of the San Isidro River in Oaxaca on 18 September 2023. Mexico's records are all very recent at two-year intervals, from 2019, 2021 and 2023, with the most recent sighting serving as the westernmost record. These recent sightings, including the 1st Galapagos record from July 2023, support the hypothesis that extralimital reports of Gray Gull correlate with strong El Nino years.
