Greetings. Every Friday, a neighbour of mine distributes an email on a natural history topic to interested locals. Today’s reads, in part:
Many Waterfowl species will nest in open tree hollows, ingeniously disguising the entrance with flybys where the pair fly close and fast in unison past the hollow with one disappearing into the hollow whilst the second
continues on, attracting an onlookers' gaze.
I had not heard of this behaviour before. Any comments/observations, please?
