Small leaf warbler, smaller and tinier than a house sparrow, about 10 cm in length, olive-green above and off-white to yellowish below, and a well defined yellowish supercilium. Nightmare to ID, because of its resemblance with Wood and Willow warblers (P. sibilatrix and P. trochilus).
This is a common eurasian leaf warbler; observed here in peripheral urban setting, on edges of Tbilisi town center but on cliffs of protected Botanical Gardens.
Unfortunately for this warbler habitat, as everywhere these days, plastic garbage introduces itself - and that plastic bottle was well beyond my reach.
Lat: 41.72, Long: 44.87
