July 2020 Quiz

JANUARY; CALIFORNIA

Age: This appears to be a large, four-year gull. Based on the rounded primary tips, muted pattern to the inner primaries and wing coverts, moderate gray on the back, and largely white tail coverts, we can safely assume this is a 2nd cycle. A 1st cycle holding on to all its flight feathers would likely show less gray on the back, and patterned uppertail coverts and greater coverts. A 3rd cycle would show adult-like primaries, or at the very least, adult-like inner primaries, which this individual does not. 

Identification: Based on the darker gray scapulars that have come in, we can eliminate paler-backed species such as the Iceland Gulls, Herring Gull and even Glaucous-winged Gull. One may ask, how do we correctly interpret the gray on the back, and this could be done by judging the white on the uppertail coverts. The white on the uppertail is a true white -- not blown out and not covered in shadow. Thus, we can visually measure the contrast between the gray upperparts and the uppertail to get a sense of gray values.

This is a broad-winged bird with noticeable white tips across the secondaries. It looks too broad winged for Lesser Black-backed and the bill appears too heavy for that species too. Judging from the swollen bill appearance and smudged head and dusky neck markings, this bird best fits a 2nd cycle Western Gull, and is actually a fairly typical bird. A 2nd cycle Yellow-footed Gull at this time of year would show some indication of adult-like flight feathers and should perhaps average more gray on the upperwing coverts. The date and location also support Western Gull.

Notes:

• The biggest surprise this month was the apparent Glaucous-winged type from Wichita County, Texas. It looks like a bona fide Glaucous-winged Gull, but bleaching on the primaries makes it impossible to ascertain previous patterns. Uppertail pattern favors Glaucous-winged Gull over a hybrid.
• 08 June 2020 - 2nd prebasic molt in motion with p1-p2 missing.
• 11 June 2020 - new p1 barely visible, just beyond primary coverts.
• 12 June 2020 - p3 missing, new p1 now clearly visible well beyond p-coverts.
• The other highlight this month is alternate adult Black-headed Gulls found in random places that they're not usually expected in the summer. Most notable is Bay County, Michigan which had not seen this species in the county in 39 years, and is now a first summer record. 
• Finally, summering Lesser Black-backeds in the interior continue to increase in the summer season, especially for the last 3 consecutive years. Colorado, Wyoming and Nebraska all reported 1-3 birds each. All of these individuals, expect for Wyoming, appear to be one-year-olds beginning their 2nd plumage cycles. 

June 2020 Quiz

June. Wisconsin.

Age:  It's safe to assume this is a 1st cycle based ont the black terminal band on the tail.

Identification: Our June bird appears to be a small, two-cycle, gull. The small, pointy bill, black pseudo-hood and thin black tips to the primaries immediately evoke Little Gull and Bonaparte's. It's difficult to judge bill proportions here, but Black-headed is safely ruled out not only by the bill's color, but also by the white under side to the primaries. As for Bonaparte's, that species would show a prominent black trailing edge running across all of the remiges. Here's an example of a typical trailing edge on Bonaparte's:

Instead, what we see here is a "spotty" black trailing edge that is discontinuous and weakly patterned, which leaves us with Little Gull.

May 2020 Quiz

Michigan. August.

Age: This month's quiz is timely with many gulls in the northern hemisphere now beginning to replace flight feathers. Undergoing a complete molt, this individual has renewed most of its primaries which have an adult-like pattern to them. Overall the upperwing and tail are far from "definitive adult" and so it is perfectly fine to assume the newer flight feathers that have come in are 3rd generation. Thus, this is the 3rd plumage cycle and the complete molt here is the 3rd prebasic molt. The old retained primary (p10) is 2nd generation.

Identification: The brownish cast to the upperparts impart a darker feel than is typical of this species. Focusing on the new primaries, it is apparent that we're looking at a paler gray species. The bill is on the heavy side, but proportionately sized with the head. The eye appears dark, but zooming in shows much speckling and paling -- this helps rule out California Gull. The wide and complete tailband, and bill pattern, are wrong for a Ring-billed Gull, among several other features. The only reasonable identification for this pink-legged, pale, large white-headed gull, is Herring Gull.
