Larus armenicus Filchagov, A.V. (1993): The Armenian Gull in Armenia. British Birds 86: 550-560. Breeding biology and behaviour Body movements during the Long Call display resembled those of the Lesser Black-hacked Gull, the head movements having a very large amplitude. At times in the Throw-forward phase, the bill nearly touched the belly, and in the Throw-back phase the head almost touched the back. Variations of this display were classified according to head position at the extreme point of the Throw-back phase: fuscus-type when the head was perpendicular to the ground surface or nearer to the back (plate 211); argentatus-type when the head-neck-back line was straight (plate 212); and intermediate-type. Of 54 displays observed, these types occurred in the ratio of 33:8:13, respectively. 211.

Filchagov’s photographs taken during his trip to Armenia were stolen in a robbery in Paris. The plates accompanying this paper have, therefore, been taken from the only remaining (rough) prints which, fortunately, had been sent to British Birds with the first draft of this paper. EDS] |
