Swarms of swifts in Baku, including around the Maiden Tower - where there was also a bright kestrel swooping in and clinging to the stonework. (Excellent Baku swift nesting relocation information can be found here: https://t.co/FxTnq1ZUAb)
And then - something else, yellowy-green and bright in the sun but somehow not parakeet shaped (and anyway they don't, according to Collins, seem to be feral here?) - and I THINK it might have been a juvenile golden oriole?
Oh, also lots of lovely urban hoodie crows, but as I recall from Mongolia many years ago, the grey seems paler than at home, almost a buff type colour.
