A neighbour destroyed their nest just before any eggs were laid. But those eggs were coming and the couple found refuge on our balcony. No time to build a nest. Around here, if not disturbed, exposed eggs like these usually get predated by Magpie Pica pica or Carrion crow Corvus corone.

Today a visit to the top floor revealed that both Black-headed Gulls Chroicocephalus ridibundus and Common terns Sterna hirundo have large young. A small number of Black-headed gull chicks has fledged by now (I ran into one in the street below a couple of days ago). The solar panels seem to provide a useful shelter to the chicks. The Herring gull pair from the previous post (no solar panels present) lost all its chicks shortly after hatching.

About three pairs of Common terns Sterna hirundo nest among the Black-headed Gulls.
Herring Gulls Larus argentatus (photo above) and Lesser black-backed Gulls Larus fuscus also nest in the area, but their nests are more widespread and difficult to detect.
