| Abstract: | Summary Savalli, U. M. 1993. The behaviour of male Yellowmantled Widowbirds Euplectes macrourus in western Kenya. Ostrich 64: 57?62. Male Yellowmantled (Yellowbacked) Widowbirds Euplectes macrourus use two displays in territorial defense. The territory boundary display involves a specific, upright posture along with the hiss-trill vocalization, but the song does not have a visual component. Courtship displays involve flicking up the wings and tail, sometimes leaning toward the female with the tail elevated, and a slow, bouncing flight display. The swivelling display described by Emlen (1957) was not observed, and seems to be replaced by the flicking displays. During the breeding season, male Yellowmantled Widowbirds defend territories from conspecifics but do not exclude Marsh Widowbirds E. hartlaubi. At night they form communal roosts off their territories. During the non-breeding season they form mixed species flocks with other finches. Male widowbirds are most active in display before 10h00, and often leave their territory in the afternoon.Summary Savalli, U. M. 1993.
