Fig 19: Larus armenicus and michahellis, frequency and occurence of three types of wing-tip patterns.
There is a significant difference in the frequency of occurrence of these three types, when the three interior colonies are compared to michahellis-colonies (chi2, p<0.001). That is, armenicus showed significantly less white in the wing-tip that michahellis (80% of michahellis has a mirror on both P9 and P10 and they more often show a broken sub-terminal band). Barabensis, scored in Lake Tengiz in Kazakhstan, also more often has mirrors on both P9 and P10 (77% of the breeding birds, small sample size, n = 22). All birds were sexed using molecular markers, and there appeared to be no sex-difference in the number of primaries with white mirrors.
The white tips of the primaries were worn by the end of May and early June. Even in fresh feathers, the primary tips are relatively small in armenicus.
Black: Type I
The breeding range for armenicus is pale-grey, the breeding range for cachinnans is dark-grey, the breeding range for michahellis is characterized by a line along the coast.
