G'day All
I've been mindful of this notion for many years
every time I come across a new Satin Bowerbird bower. In my experience the
reality doesn't measure up to the yarn, I'm afraid.
I believe that the idea is that if the bower is
facing north-south, the male can parade his satin sheen very nicely in the
sunlight to any bird that may be standing in his bower. However, I've had
Satin Bowerbird bowers facing east-west. They could well be designed/positioned
so that at least some part of the day the bird can dance about in the
sunlight which may be the key.
It's certainly entirely untrue of all the other
avenue bower builders too.
Happy birding
