November 2020 Quiz

 

Indiana. May.

AgeA large four-year gull with two generations of primaries showing. Primary replacement well underway. The 5 inner primaries are new, 2nd generation feathers, and thus this individual is in its 2nd molt cycle. All secondaries are 1st basic.

Identification: Overall the head, body and uppertail are very white for a four-year gull in early 2nd cycle. The thin tailband and overall peppered plumage aspect are reminiscent of Great Black-backed gull. The ginormous bill and stealth-bomber body with long thick legs all help identify this as a Great Black-backed Gull. 

Indeed, the field-readable leg band "Black 3U4" trace this bird back to its natal colony of Appledore Island in Maine. More on this individual here

October 2020 Quiz

 

Washington. January.

Age: This is one of our four-year gulls. Almost everything looks okay for an adult, but the dull bill pattern with black near the tip, and darker greater primary coverts (just below the drooping white secondaries at the base of the outermost primaries) suggest a subadult. Here, subadult means a bird that's mostly adult, but with one or two imperfections. This is a vague term for what could be a very advanced 3rd cycle type, 4th cycle, or perhaps an older bird with some retained "subadult" features. 

Identification: Given the location, let's start with the expected pink-legged taxa: Western and Glaucous-winged Gull. The gray upperparts look a tad darker than a typical Glaucous-winged and slightly flatter and paler than Western. Also, the dusky gray primaries are intermediate between the black on Western and pale to medium gray of Glaucous-winged. You may already be on to where this is going. Intermediate individuals such as our October Quiz gull are freely assigned to the hybrid population of this region: Glaucous-winged x Western, or Olympic Gull. They often have more bulbous-tipped bills than this one, but we might attribute this to our bird being a slighter female. The smudgy head, neck and breast markings are expected on both Glaucous-winged Gull and Olympic Gulls, and to a much lesser extent, on Western Gulls (subadults). 

It bears mentioning that birds with this amount of pigment on the primaries are routinely identified as pure Glaucous-winged Gulls in far northeast Asia. From southern Alaska down to central California, Glaucous-wingeds with this degree of pigment on the primaries are often suspected of having either Herring or Western influence. However, there are apparent pure Glaucous-winged Gulls with darker primaries matching our bird. Those birds should score perfectly in other areas such as wingtip pattern, gray upperpart coloration, eye color, orbital color and bill color/pattern.

Notes:
1. There was an above average presence of Little Gulls throughout the lower 48 this month, many in mostly fresh juvenile plumage. 

2. Lesser Black-backed numbers were likely the highest they've ever been in September throughout the interior, especially in the far southwest United States.

3. A 2nd cycle type Red-legged Kittiwake was observed for less than an hour in Deep Bay (Vancouver Island). This appears to be the 2nd occurrence of this species in BC.

September 2020 Quiz


Wisconsin. February.


Age: Profile and stature suggest a large-white headed gull. An open wing would be helpful for such a plumage aspect, but the overall muted and plain pattern to the tertials and upperwing coverts, as well as the amount of adult-like gray on the back, suggest a 2nd cycle type gull. The primaries, particularly p7-p8, are gently rounded at the tips, which should help move us away from 1st cycle. The bill pattern, with yellow on the nail, is also more expected on an individual beyond its first cycle. 

Identification: Beginning with the primaries, we note a dark brown coloration -- not black -- with prominent pale edging, especially on p5-p6 (closest to the tertials). The tertials are a couple of shades paler, encircled with a pale outline. The coverts become a shade paler than the tertials and have a noticeable frosty look. And so from the wingtip to the lesser coverts, the bird gradually goes from dark to pale in an even manner.  Structurally, the bill is relatively thin with no noticeable buldge at the gonys. The head is nicely rounded, and the head and breast markings are more smudged than streaky. Also helpful here as a supporting field mark is the vividly pink legs. All of this points toward a white-winged gull -- too lanky and small-billed to be Glaucous-winged, which leaves us with Iceland Gull. 

Additional Comments: Note that Glaucous-winged x Herring Gulls can approach this plumage aspect. Those hybrids tend to have a heavy-chested appearance, as well as more body behind the legs and slightly shorter-looking wings than this. But surely there are instance when these two -- Thayer's and Glaucous-winged x Herring hybrids -- can be difficult to separate.
