dc.description.abstractOver the last 20 years drastic changes have been recorded in the composition of a flock of Lesser Kestrels Falco naumanni and Amur Falcons F. amurensis at a roost on the campus of the National University of Lesotho at Roma. Numbers of the latter have increased, while those of the former species have dramatically decreased. Changes in the number of Amur Falcons recorded in February – March suggest that their southward migration continues until early February and soon thereafter a departure north starts, with most birds vacating the roost in the first half of March. The earliest arrival of Lesser Kestrel was 26 October, the latest departure 9 April. The earliest arrival date of Amur Falcon was 19 December, the latest departure date 7 April. Early-morning departure from the roost lasted for up to 40 minutes, but most birds left during the first 5–10 minutesen_US
