Took these photos of a White-faced heron feeding around the carcass of an EGR on the Kings Hwy one morning a few months ago.  You will notice the European wasp in one of the photos - it can be seen flying in front of the heron's face.   The bird was feeding there for a few mornings running.
Apologies if the attached files are too big.
