>> GENERAL >>>>><\/strong><\/p>\n

– medium-sized falcon, size roughly like Common Kestrel<\/a> but longer wings
\n– breeding in Asia, vagrant in WP
\n– diurnal migrant, but regularly non-stop sea-crossing between India and Africa takes place
\n– migrates singly or in often large loose flocks, in WP sometimes mixed with Red-footed Falcon<\/a><\/p>\n

\nBIF2815, 25\/08\/2017, Dornod, Mongolia, Mathias Putze

\nBIF2817, 25\/08\/2017, Dornod, Mongolia, Mathias Putze

\nAmur Falcon Falco amurensis<\/em>, F AD<\/strong>
\nBIF1583, 23\/05\/2011, Kherlen Gol, Mongolia, Mathias Putze
\n– fine barring of underwing-coverts, arrowhead-type body feathers and tail pattern suggest AD F
\n– light F with regular barring from primaries to secondaries (compare to BIF1581)<\/p>\n
