The bird we most commonly associate with Venice is of course the humble pigeon. They flock to Piazza San Marco to hoover up the scraps dropped and thrown by the larger flocks of human traffic, leaving only when the lagoon steps in to flood the area from time to time. Seagulls are similarly unsurprising sights; the green waters that lap at the foundations are sea water and, despite the efforts of the industrial Mestre nearby, do contain fish.
I was surprised to see a little egret perched upon a barrier in the shadow of the Rialto bridge however, for this is a bird I associate more with Africa. Still they have even been finding their way to England in recent years so perhaps its presence is not so unusual. I still couldn’t stop a pigeon from gate-crashing though.
