Cross-dressing in the wild
These she-males have also started acting differently. They aren't attacked as much as the hawks that look male, but they do tend to be more aggressive. They defend their winter roosts more, recruited by the he-males to do the fighting and other dirty work. And when they are aggressive within their own species, it is directed more towards females instead of males.
But these personality shifts are not the reason for the physical changes. It is possible, like another bird species that has changed their features, that these birds may be doing this so they can get closer to the female hawks while avoiding competition. They can get "some" easier than those males with traditional features.
Birds are not the only species that do this. Garter snakes also mimic their female counterparts. After males come out of their winter dens, they emit female pheromones that attracts hundreds or more males. But their main goal is to get warm. In these huddles, enough body heat is produced that enables them to warm up after a long winter.
This article goes along with one of my earlier posts, the one about the squids who seemingly have bisexual tendencies. In the wild, there isn't a lot of uproar about animals doing whatever it takes. They aren't necessarily doing these things because of sexual preferences, but because of traits that have developed to increase their chances of survival and reproduction. This makes me wonder what types of tendencies have naturally developed within the human population? Did something over time trigger sexual preference changes in humans or are they just personal preferences that have always been there but have recently begun to surface more?
