sub-adult (4cy / 5cy): January - April

Sub-adult LBBG in 4cy and 5cy very much resemble birds in adult plumage. On average, 4cy birds may still show a few immature features, but on the other hand some 4cy match the average adult very well and may be difficult to identify.

Only very few sub-adults remain in the Netherlands during the first three months of the year. Together with adults, sub-adults return to the colonies in spring and maybe a few will already breed. It's difficult to separate sub-adults from adults, although sub-adults normally show:
- some black on the bill
- pale yellow legs
- or no pure yellow irises.
However, this may occur in adults in winter plumage as well.

Best features to distinguish sub-adults from adults are:

- less developed primary tips,
- less developed primary mirrors (but beware of smaller sized mirrors in females, normally only showing a P10 mirror),
- extensive black on the bill,
- extensive wear in the coverts with a brown hue, already early in spring and sometimes a hint of barring.


3CY Lesser Black-backed Gull with classic pattern on 2nd gen primaries and secondaries: extensive brown brown on inner primaries, often complete outerwebs dark brown, lacking well demarcated sub-terminal markings. Tail might be anything from classic 2nd gen (broad tail-band over all feathers) to completely white tail.


4CY Lesser Black-backed Gull. Almost similar to 3CY bird above, when you compare tail and combination of brown and grey wing-coverts. However, note difference in secondaries and primaries. Inner primaries P1-P2 adult-like grey and central primaries with black sub-terminal markings and clear-cut white tips. Secondaries with broad white tips, and especially innermost secondaries show adult-like grey base.


sub-adult Lesser Black-backed Gull. Almost similar to adult birds, with adult-like inner primaries and central primaries with black sub-terminal markings and clear-cut white tips. Secondaries with broad white tips.
