Other than one rescue budgie we had, none of our mostly rescued birds have been human-imitative talkers. After volunteering for 4 months at a parrot shelter, I've begun wondering how special the natural "songbird-like" vocalization streams of budgies may be among all parrots. I've heard all kinds of vocalizations from the many other, larger species at the shelter, and a lot of very engaging imitative sounds, but nothing I would characterize as 'singing,' happy sounding runs of chirps, "choy, choy, choy", whistles. Sometimes broken up with squawks or yells but settling back down to pleasant little babbling runs. You probably know just what I mean.
The males are specialists at it but most of our females have also been good little songstresses, happy-talking away sometimes simultaneously with their male companions, especially when there's higher pitched sound in the room such as TV shows with a lot of applause.
A bird's song is a focus of Nature VS Nurture. A lot of the time it is a mix between what it has learnt from parents, picked up from other birds, noises that he or she has found work well in their song; and what is instinct. Budgies and other parrots specialize in copying and therefore their song will mainly consist of things he or she has found where other species usually have a characteristic song for the species as this is what works when attracting a mate! It really is a beautiful and complex work of nature but all it boils down to is the individual and it's species
