Hello! Could you please help with the ID of this falcon? At first, I went with ad. Saker, but I'm wondering, could the other possible choice be F. peregrinus ssp. calidus? The thing that's bothering me is the very pale underparts with no distinctly darker underwing greater covers. Could juvenile calidus have that much of its juvenile feathers (brown upperparts) in this time of the year? Also, the undertail coverts seem to be striated and the colour of the feet - bright yellow. 19.03.2023, Southern Bulgaria.
