I guess that seabirds and waders will go into two massive separate posts. Here I am going to show few photos (sigh) of the remaining birds. I have seen the common buzzard (Buteo buteo), the common pigeon (Columba livia), the common woodpigeon (Columba palumbus)...and that's it! So, I should really do birdwatching more often.
