This 500g/1lb bird stands about 57cm/24inches high is very difficult to photograph. I'm not sure whether it's shy or whether my dogs (especially Eddy who loves to chase birds) have frightened it in the past. Debbie grabbed my camera and managed to get a few photos before it took off in flight.
If you enlarge the first photograph, you will see where it gets its name from. The Hamerkop (which means "Hammerhead" in Afrikaans) has a distinct backward projecting crest. It's diet consists of frogs, tadpoles, aquatic insects and small fish. It would get the first three in my pond but that day it did not stay for dinner.
