Contraception and narcissism?

Ahem. Now that I have your attention with that title....

We have mirrors in our garden for visual challenges and spreading winter light. They also entertain birds, especially wrens, but also blackbirds. Blackbirds are a troublesome introduced species in Australia. They have fine voices but are survivors which compete vigorously for habitat with less assertive native bird species.

Here is a movie of a female blackbird at a mirror. Raising the question of whether the infatuation with the bird in the mirror provide some contraceptive limitation to the spread of blackbirds, at least in our garden.... :-)

(We have at the moment only bowerbird visits, the dancing pavilion area is a bit bare and exposed in the end of winter and with essential pruning.)

every blue item gone, but flowers that bloom in the spring tra la

I have a camera out there to record the vanity of the blackbirds that spend extraordinary amounts of time dancing and pecking at their own images in mirrors, clack-clack. But the blue items of the bower and stores of them under adjacent tree, are all taken away. Bowerbirds visit briefly, but winter (and some pruning) have reduced for now the privacy of the bower pavilion space.

Rattleberry has his eyes on the scene, this early morning.
