Abstract

We analysed the display behaviour of male little bustard Tetrax tetrax to identify displays that are used in the context of male-male competition andthose that are used for attracting females. Courtship was the main activity of males during the breeding season. Calling activity occurred throughoutthe day, and leks were attended for more than 4 months. Male sexual displays included snort call. wing-flash, and jump display. Snort call was performed throughout the day and mainly involved male-male interactions. In contrast, the wing-flash display was given only at twilight, and was performed most commonly when a female was present, supporting an inter-sexual functionfor this display. The jump display was performed only in the presence of female at anytime of the day. Analysis of individual variations in display behaviour revealed that intra-individual variation was low compared to inter-individual variation, especially for the jump display. It is, therefore, possible that display rates provide information on male quality. Four male settlement patterns could be defined, singles, paired, lekking and satellitelekking, but only wing-flash display and stamped snort call differed amongthose categories. We suggest that satellite males are attempting to benefit from proximity to higher status males, in accordance with the hotshot hypothesis of lek evolution.
