On Sunday we went for a walk up from Bibra Lake.
Whilst at the lake we found an egg exposed out on the sandy bank. It looked like a duck egg and it was still warm to touch. There were some pairs of ducks roosting, head under wing, further down on the edge of the water. Just as I stood there a very persistent and quite unafraid crow came down to take the egg.
Whether these are the ducks (Australian Black Duck) that laid the egg is unknown (there was another pair nearby and none of the ducks were near where the egg was laid)
