Could someone post photos of the Besra - preferably showing them in flight.
I am working on a raptor migration project in Thailand and we need visual information about how to ID the juveniles and adult Besras from other sparrowhawks such as Japanese S; Chinese S.; Shikra; Crested Goshawk; and even Eurasian Sparrowhawk (rare) - all of these have been seen here. We suspect Besra may be a rare migrant but need some visual guides.
Thank You,
