Office birding

Fortunately I have a very nice view from my office window, so I can't avoid seeing birds also during work hours. This morning the weather was bit foggy, but when the fog disappeared, there was a lot of move in the sky. Within few hours I saw for example Northern Lapwings (Vanellus vanellus), Common Skylarks (Alauda arvensis), Whooper Swans (Cygnus cygnus), Common Woodpigeons (Columba palumbus), 1 Eurasian Sparrowhawk (Accipiter nisus), Common Gulls aka Mew Gulls (Larus canus) and Black-headed Gulls (Choirocephalus ridibundus). Well, nothing special indeed but not a bad observations during phone meetings and writing documents...
