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.
