black and white pattern of remiges in JUV and F different to the brown bands on darker brown ground of remiges of Eurasian Hobby, sexing by broad black barring of JUV tail feathers, M are supposed to have at least a few greyish parts in body at June, if parts of the tail are moulted, these feathers have to be completely grey, aging by heavily barred underwing and mostly JUV tail feathers (three moulted AD-type inner tail feathers with thin black bares to wide grey gaps), body feathers still very similar to 1CY-birds

still JUV black and white barring of underwing-coverts (brownish in Red-footed Falcon, BIF1569), first grey body feathers and reddish at trousers, but face still JUV, worn tips of primaries typical for 2CY birds

Amur Falcon Falco amurensis, F AD
BIF1583, 23/05/2011, Kherlen Gol, Mongolia, Mathias Putze
finely barring of underwing-coverts, arrowhead-type body feathers and tail pattern suggest AD F, quite light F with regular barring from primaries to secondaries (compare to BIF1581)

from above very similar to Red-footed Falcon, beware of the light conditions and try to catch a view from the underparts (compare with BIF1567)
