Notes: 
1. Angela MacDonald found an adult type taimyrensis in New Glasgow, Nova Scotia on 04 January 2021. A darkish eye, fine streaking restricted to the lower hindneck and a sherbert-orange/yellow leg color support this taxon. Late primary molt is also in favor of this Asian form. P1-P7 new and fully grown, P8 80% grown, P9-P10 retained. P10 with medium to large mirror, P9 with small rounded mirror not reaching the outer web. Black on P7/P8 reaching p-coverts along the outer webs. Full, asymmetric subterminal band on P4, and black mark on outer web of P3 (on right wing). No white tongue tips on P6-P7, with very little slivers of white on inner webs of  P4-P5. The taxonomy on Taimyr Gull is unsettled. Some authorities treat it as a hybrid population between Heuglin's and Vega Gull, others place it with the Lesser Black-backed Gulls. A recently adopted position on this form is that it is a good taxon worthy of species rank.

January 2021 Quiz

 


Washington. January.


Age:
There is no reason to suspect this isn't an adult. On the underwing, we'd be looking for black markings on the tail, hints of dark centers on the secondaries and darker wing linings -- none which are seen here.

Identification: This appears to be a "white-winged" species, lacking black on the underside of the outer wingtip. The ghostly gray remiges, darkerst on the outer 5-6 primaries suggest Glaucous-winged Gull or a Kumlien's type Iceland Gull. The proportions -- long and broad wing, long tail, barrel-chested body, thick neck, and above all, the stout, bulbous-tipped bill -- all support Glaucous-winged Gull. This Glaucous-winged Gull was photographed in the Olympic peninsula region, and is the expected white-winged large gull here.

December 2020 Quiz

 

Wisconsin. June.

Age: The primaries are 1st generation, as are the brown median/lesser coverts and tertials. It's also likely the greater coverts are 1st generation, and the different color here is due to a combination of a paler pattern on this tract and wear. The gray scapulars are likely a mix of 1st alternate and formative feathers. Note also hints of a black distal tailband just below the primaries. Thus, we will assume this is a 1st cycle, but May-June is prime time for the start of flight feather molt, and only an open wing would reveal if the 2nd plumage cycle has "formally" commenced. 

Identification: This is a small tern-like gull. The petite bill and short tarsi suggest the smallest of the sternine gulls. The black cap can be found on Bonaparte's at this time of year, but this head pattern, along with the solid brown covert band across the wing panel supports a different species. The black and white saw-tooth pattern on the primaries readily identifies this individual as a Little Gull.

The official longevity record of a known-age Great Black-backed Gull in North America is 26 years 9 months.


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
