Liver Birds.

Liverpool Life Discover the city’s hidden flock of Liver Birds in the Liverpool Echo:

"Liverpool's hidden Liver Birds Scattered around the city are lampposts covered with Liver Birds - like this one outside the Liverpool Museum on William Brown Street.

"As emblematic guardians of their city, the two huge birds standing on top of the Liver Building can punch their weight – all four tons apiece – with any landmark around the globe."

That would be quite some crowd sourcing project for people to collect liver birds from throughout the city, not the flickr doesn't have a decent selection already.
