I have been calling all my “green” birds females, when in fact, young males resemble the adult females. I normally see an adult male and a green bird come in together …and was calling them a pair. So my small flock can be a mixture of mature birds and adolescent males…as well as females.
The mature males are all in bright color. They usually head for their breeding grounds sometime around April. Today is April 1st and they are still here…Perhaps they will stay and raise their young nearby.
