Mew Gull (Larus canus) 2nd cycle (3CY): January - February

Mid-January 2017 a strong winter-storm hit the coast of the Netherlands and beached myriads of mollusks and starfishes, which in turn attracted large numbers of gull, including Iceland, Glaucous, Herring, Lesser Black-backed, Greater Black-backed, Caspian, Yellow-legged, Little, Black-headed, Mediterranean and Common Gull.

Especially on sunny days you'll find joggers, horse-riders, people with dogs, etc frequently passing by at close range, or even chasing away birds. Gradually the birds got used to it and with a little care could be approached. We rarely have Common Gulls in large numbers being this confiding; here is a link to a set of pictures of 3CY birds (2nd cycle) in January. All pictures January 27 2017 - Scheveningen beach. (picture is link to index page)

Some species, especially the smaller ones like Little Gull (top row) and Black-headed Gull (second row) attain adult plumage in 2 years (summer of their 3rd CY). Next rows illustrate the plumage development of Mediterranean Gull and Mew Gull, species inwhich it takes 3 years to get the adult plumage. Lower rows illustrate Lesser Black-backed Gull, Herring Gull and Great Black-backed Gull.

Mew Gull - Mew Gull - Ring-billed Gull

Mew Gull Larus canus is an abundant winter visitor and common breeding species in The Netherlands. Two Nearctic gulls look quite the same, but can be identified in all plumages. Ring-billed Gull delawarensis is a very common and widespread species in Canada and the USA, Mew Gull brachyrhynchus is a bird of the north-west and has the main winter area along the West Coast. Due to distant breeding grounds and their migration routes, the latter species may not be a prime candidate for turning up at our beaches, but nonetheless there have been claims, e.g. a trapped bird at Klitmøller, Thy, Denmark in February 2010. Ring-billed Gull is an annual vagrant to Europe and several birds (returning birds in winter) have been well documented in the past.

When seen well, Ring-billed Gull is characteristic in adult plumage, showing:
- black ring on yellow bill
- yellow iris
- much black in wingtip, including broad sub-terminal band on P10
- small mirror on p10
- small white primary tips
- yellow legs
- pale grey upperparts, Kodak 4-5.


Ring-billed Gull delawarensis adult, April 2007, Toronto, Ontario, Canada (Wikipedia).

First cycle (first winter) Ring-billed Gull is a bird inbetween Mew Gull canus and Herring Gull argentatus, especially female argenteus. Ring-billed Gulls first impression is a large Mew Gull, od medium size with a pink-based bill and much contrast between back and wing-coverts. Like Comnmon Gull, they develop a grey back, 2nd gen scapulars in Herring Gull strongly patterned with anchor-shapes, and Ring-billed Gull may frequently replace wing-coverts in the post-juvenile moult (sse picture below, right bird), not replaced in Mew Gull nor Herring Gull. Image below (left bird) shows the flat head and stronger bill than in Mew Gull, and also the more chequered greater covert pattern (plain greater coverts in Mew Gull, lacking barring and lining), but some Ring-billed Gulls may show plain greyish greater coverts as well, and remember when coverts have been replaced 2nd gen coverts are plain greyish as well.

Ring-billed Gull delawarensis 1st cycle, January 10 2013, Florida (Christine Dodding). Pink base of bill. Chequered pattern on greater coverts. Side of breast and flanks not clean, but chevron (arrow-head pattern) pattern on flanks.

Chequered pattern on greater coverts very worn. Side of breast and flanks not clean, but chevron (arrow-head pattern) pattern on flanks.

Ring-billed Gull delawarensis 1st cycle, December 30 2012, Louisiana (Ronnie Maum). Pink base of bill. Plain grey on greater coverts. Proximal half of tail also with lining and spotting.

Ring-billed Gull delawarensis 1st cycle, December 30 2012, Louisiana (Ronnie Maum). Dense chevrons on flanks and side of breast. Chequered pattern on greater coverts. Proximal half of tail also with lining and spotting.

Mew Gull canus 1st cycle, January 02 2011, Warmond, The Netherlands (Maarten van Kleinwee). Most of the scapulars replaced. Few dark markings on upper tail coverts, and tail with broad dark band.

Mew Gull canus 1st cycle, January 29 2011, Leiderdorp, The Netherlands (Maarten van Kleinwee). Scapulars replaced, all wing feathers (coverts, tertials, secondaries and primaries) are first-generation, brown feathers. Especially the median and greater coverts look bleached.

Mew Gull canus adult, April 19 2006, Bergen, Norway, (Frode Falkenberg). Dark iris. Mew Gull brachyrhynchus, June 14 2012, Denali NP, Alaska, (Glenda Suebee). Paler iris and slender, finer bill.

Adult summer Mew Gull probably is not the first plumage to be expected in The Netherlands. Therefore this page focus on Mew Gull brachyrhynchus vs Mew Gull canus in 1st cycle, 2nd cycle and adult winter plumage. Below is a list of "classic" differences, which may be more prominent on one bird than it is on the other, so please always consider individual variation in either taxon.

Classic Mew Gull canus in adult winter:
- very dark iris,
- band on bill,
- bill colour rather greenish yellow, not vivid yellow,
- leg colour rather greenish yellow, not vivid yellow,
- very delicate fine spotting 'often pencil streaking' on winter head,
- this spotting concentrated on crown and not in hindneck; also not running down to sides of breast (clean breast),
- short tongues op P10-P8,
- very large mirror on P10 often completely merged with white tip,
- large mirror on P9,
- sub-terminal black on P6 points upwards along outer edge of feather,
- often no or little black on P5,
- large white tips on outer primaries.

Classic Mew Gull brachyrhynchus in adult winter:
- speckled, but medium dark to paler iris,
- even in winter no band on bill,
- bill colour more vivid yellow,
- leg colour more vivid yellow,
- blotchy, mottled winter head,
- this mottling concentrated in hindneck (which sometimes solidly dark); also running down to sides of breast creating scally pattern,
- long tongues op P10-P8, tongue of P9 >50% of visible length,
- obvious white tongue tips 'string of pearls' with sharp division between white and grey on P8,
- medium-sized mirror on P10 often with complete sub-terminal band,
- small mirror on P9,
- black on P9 not reaching prmary coverts,
- sub-terminal black on P6 of evenly width, not upwards along outer edge of feather,
- often broad 'symmetric' black band of even width on P5,
- sometimes spot on outeweb of P4,
- outer primary tips becoming smaller outwards,
- inner primaries and all secondaries with large white tips.

EXTRA'S
- delicate small head on long-looking neck,
- delicate fine bill,
- slightly darker than Mew Gull canus,
- P10 patterned like cachinnans, canus more like michahellis.

IMMATURE PLUMAGES, COMPARISON OF CANUS (LEFT) AND BRACHYRHYNCHUS (RIGHT).

In first cycle (= 1st winter) birds, all flight feathers (tail, secondaries and primaries) are still juvenile; as winter progresses the only process to consider is wear and bleaching. Hence, patterns on primaries and especially tail remain the same throughout the period until a complete moult in summer will replace all these larger feathers.
Mew Gull in first cycle is easily told apart from Mew Gull by tail, uppertail coverts and rump. Like in many American gull species, the tail is largely blackish, and uppertail coverts are densely barred. In resting birds the most eye-catching feature is the solidly patterned pale brown hindneck, this texture continues on the side of the breast and may sometimes be apparent on most of the underparts. Once the mantle and scapulars are replaced in Mew Gull, there will be a strong contrast between these new grey feathers and the brown "shawl". In Mew Gull the hindneck may be brown as well, but this is often blotchy and showing stripes or scaly pattern.

Below some example birds, with Mew Gull canus (left) and Mew Gull brachyrhynchus (right).

Mew Gull brachyrhynchus 1st cycle, September 28 2012, SSM Landfill, US. (Kirk Zufelt). Blackish tail, dense barring on uppertail coverts. Juvenile plumage. Note thin fringes on tertials. Solid brown on hindneck and side of breast.

Mew Gull canus 1st cycle, January 25 2009, Cascais, Carcavelos, Portugal. Picture: António A Gonçalves. Some 1st cycle Mew Gulls get blotchy in the hindneck, but still there remains a spotting pattern, more obvious on the crown and ear coverts. Note much white in the tail.

Mew Gull brachyrhynchus 1st cycle, October 31 2011, Virginia Lake. (Kirk Zufelt). Very mottled texture connects hindneck with breast and belly. Broad bands on undertail coverts.

Mew Gull canus 1st cycle, January 02 2011, Leiden, The Netherlands (Maarten van Kleinwee). Breast-pattern of first-cycle Mew Gulls is quite variable: from pure white, dark-patterned flanks, to fully-dark breast and flanks as shown in this individual. However, dark hindneck not solid, no shawl, but striped and spotted.

Mew Gull brachyrhynchus 1st cycle, February 02 2011, Washington (Dennis Cheasebro). Blackish tail, texture connects hindneck with breast and belly, overall simple pattern (actually no pattern) on coverts. Note worn plumage.

Mew Gull canus 2nd cycle, November 10 2012, Esbjerg, Denmark (Graham Ekins). Bill and and dark iris. 2nd winter canus may have head streaking more mottled and blotchy. Lacks black ink spots on tertials and tail.

Mew Gull heinei 2nd cycle, January 2010, Copenhagen, Denmark (Kjeld Tommy Pedersen). Measurements indicate heinei. Heinei more often tend to show immature markings to a large extent in 2nd winter. Note elongated head and compare to rounded head and fine bill of Mew Gull.

Mew Gull brachyrhynchus 2nd cycle, January 03 2012, Sayer's Park, WA. (Amar Ayyash). Ink spots on tail, broad white tips on secondaries.

Mew GullS FROM THE EAST, SSP KAMTSCHATSCHENSIS AND HEINEI.

West European canus is replaced graudually in central Russia by slightly larger ssp heinei, and further east by the even bigger ssp kamtschatschensis. Especially large male heinei can be safely identified on measurements in the hand; and every winter bring at least a few heinei into our region, as confirmed by trapped bird by ringers. However, also in the field some heinei can be identified in a group of Mew Gulls, based on careful examination of open wing differences between heinei vs canus. In general, the wingtip pattern for heinei has more pigmentation and the grey tone on upperparts is distinctly darker. Subbtle differences in adult plumage:
(i) heinei more often show a deep black full subterminal band on P5; where canus normally has a thin, uneven or broken band, or black only on one web.
Sometimes, adult heinei may show a black spot on the outer-web of P4;
(ii) in heinei, black pigmentation extends all the way to the primary coverts on P8, where canus only has this black reaching 50-75% of the primary;
(iii) heinei shows extensive black on P7 (more than 80% of the way to the primary coverts); while canus has mostly less than 50%;
(iv) in heinei a long black 'bayonet' on the outer web of P6 extends for approximately 65% of the way to the primary coverts, while the maximum in Chris Gibbin's canus sample is 53%, with most having black only 20-40%.

The overall result of these details is a wingtip that has a lot more black and less white than canus.

Mew Gull kamtschatschensis 1st cycle, January 25 2012, Jinzhou Bay, China (Terry Townsend). Dark brown, well marked upperparts and barred uppertail coverts. Moult seems to be later than in ssp heinei.

Moult seems to appear somewhat retarded compared to ssp heinei: still black markings in tail and on several secondary centres. Extensively brown in greater primary coverts. Many coverts have brownish fringes, which may proof to be a good feature of second winter kamtschatschensis.

Mew Gull heinei adult, December 29 2012, Aktau, Kazakhstan (Kadirov Aisagali). Deep black full subterminal band on P5; black pigmentation extends all the way to the primary coverts on P8, extensive black on P7, in this bird there is a slight bayanoet on P7, not on P6.
