Bowerbirds are also pretty competitive
and will sometimes resort to going over to another bird's bower to steal stuff or mess it up.
As a result, male Bowerbirds put in a lot of thought
and hard work to make that good visual first impression on the ladies.
Bowerbirds: When looking for a mate,
Bowerbirds(found in northern parts of Australia) put in a little more sophistication and effort into the process unlike a lot of other animals.
If you Google around for pictures of a Bowerbirds nest, it's rather impressive to see
just how creative they can get with their decorating.
That said,
it has also been observed that the most popular male Bowerbirds have it all-
good looks, the artistic talent displayed through their beautiful homes and the most charm, courting their ladies with song and dance.
The younger female Bowerbirds are quick to judge a book by its cover, or
in this case, a bowerbird by his bachelor pad and they pick the male with the best looking bower.
These studies are largely based on“costly signalling theory”- a model borrowed from evolutionary biology which suggests that conspicuous displays that are difficult to acquire,
such as the elaborate and colourful nests of Bowerbirds, serve a vital function in signalling one's desirable traits.
However, the more mature female Bowerbirds(once she's already fallen for the guys
with the fancy bachelor pads and mated a few times) aren't so easily impressed with just their homes and start looking for more of a courtship from the male himself.
