Hello all,
Just above the nest of 'my' Willy Wagtails (on a different
branch), there is a nest of Magpie Larks. The two species seem to get
along fairly well, but today I saw something a bit more interesting. The
two of them collaboratively chased out a magpie from the tree, the lark
'mother' being the only bird that remained in its nest, and the Willy
Wagtail singing victory (I think he was trying to cuckold the poor unwary
magpie-lark, a few metres away on the tennis court fence), having
returned to its nest. Is this common behaviour?
I now have strong suspicions there are two families of wagtails in
the tree, but the other nest I cannot see. There are never fewer than
three willy wagtails in the surroundings, and occasionally, three of them
are on the tree.
