Olivaceous Warbler (Ωχροστριτσίδα- Hippolais pallida)

There was a thought that this bird could be an Olive-tree warbler but it turned out to be an Oivaceous warbler(Thank you Niko for the help in identifying it).
Although it is a common bird this is the first time we see it at the airport area raising the total number of species recorded to 151.
