OK. Pavel, please look avibase taxonmy (link), which recognaze refectus as part of species (?) named as Buteo [buteo, refectus, japonicus, bannermani or socotraensis]. Absolutely unclear situation. Why this bird is not japonicus? Good question in my opinion. [....]
Sorry, Pavel for a long time silence. Regarding culminatus taxon, first, not all of Authorities regognize this taxon as a full species (avibase), second, in case I split Large-billed Crow to three independed species users and visitors of this website [....]
A warbler. Looks good for a Blyth's Reed Warbler, considering the time and location of sighting.
