New papers on the Honey buzzard migration!

Agostini N., Chiatante G., Gustin M., Cento M., Von Hardenberg J., Dell'Omo G., Panuccio M. 2021. Local and regional wind patterns affect spring migration magnitude, flyways and flocking of European honey-buzzards Pernis apivorus at the Strait of Messina. Ardeola 78: 373-390.                           

This study investigated the influence of wind conditions on the migration patterns of European honey-buzzards across the Strait of Messina. Simultaneous observations occurred at four watchpoints, three on the Sicilian side and one on the continental boundary (Calabrian side). The magnitude of honey buzzards spring migration at the Strait is strongly affected by wind patterns in the Sicilian Channel the previous day. By interpreting migratory behaviour both at local and regional scales, this work can help to plan more efficient monitoring of honey buzzard and improving the efficiency of anti-poaching efforts. 

Cento M., Malpassuti V., Dell'Omo G., Agostini N. 2021. Differential timing of autumn migration between sex groups in adult European honey buzzards Pernis apivorus. Avian Biology Research.

Previous studies concerning timing of autumn migration in relation to sex groups in adult European honey buzzards provided contrasting results. In particular, a field survey made in southern Sweden did not report differences in timing, while a satellite study via GPS tracking on six adults, three males, and three females, revealed that the latter departed earlier. The aim of this 4-year study (2016-2019) is to further investigate the timing of autumn migration in this species carrying out observations at the Strait of Messina. Adult European honey buzzards concentrated the passage between late August early September, with females passing on average 5 days earlier than males. It is suggested that a different role of sexes concerning exhibition of territorial displays during the late breeding season, would explain differences between sex groups in timing of both moult and autumn migration.
