Steppe Gull barabensis adult, March 20 2010, Dubai, Oman. Picture: Chris Gibbins. The number and size of primary mirrors varies: this bird has only a small mirror on P10, while others also have a mirror on P9. The most frequent pattern is for black to extend inwards to P5 as a broad black band, very like michahellis. Many, like this bird, also have a black spot on the outer web of P4 |
