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 have increased, especially for the last 3 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.

April 2020 Quiz


Age: An apparent large white-headed gull that appears to be beyond its 1st cycle. Notice the marbled inner greater coverts and lower tertial edges. Also, there appears to be three generations of median coverts. The mid median coverts are oldest. These worn and frayed feathers are likely 2nd basic. The outer median coverts are fresher and may have come in with a later 2nd prebasic wave (along with the lesser coverts). The darker gray inner medians are very likely 2nd alternate. All in all, the upperparts do not fit a 1st cycle. It's difficult to make out primary-tip shape or patterns, but the very small and indistinct white tips to p6-p7 on otherwise black primaries are expected on 2nd generation flight feathers.

Identification: This is a four-year gull with an apparent long wing projection, prominent gape with a "frown", a dark post-ocular line, pinched in forehead, straight tubular bill with a familiar distal-black, proximal-red pattern on the tip, bluish tibia, heavy lower neck markings, and medium gray upperparts coming in. The gull in the background is a heavy-billed Western Gull giving us a very good sense of overall body size and shape. I hope by now you've settled on California Gull if you were unsure about our April quiz. Many people nailed this one without a problem this month but were tripped up by plumage/age. One final note on that, notice the very tip to the bill. In 1st cycles, the tip is typically all black, similar to that we see in many 1st-2nd cycle Glaucous.
