Part of this study talks briefly about BFA's basically having names for each other within a flock in order to better communicate. Or at least that's what I take from it. Never the less although a bit dry to read, kinda interesting.

Thank you Kimba! I am going to print that out so I can read it. I read a little bit of it online and it does look very interesting.

Very interesting but I did not understand the same thing you did, Kimba. They do speak of individual recognition through vocalizations but not through a sound that would represent a 'name' but because each bird has a different voice and even though the sounds themselves are the same and uttered at the same time of the year (they did determine that their calls are seasonal and their songs territorial), their calls record differently in their instruments (the same way that a human singer's voice would appear different than another singer) so they speculate that it is possible that they identify individuals from their flock through their different sounding calls. I don't know why they even doubt this. Parrots can recognize different human voices so it stands to reason that they would differentiate the voices of different individuals of their own species even better.

Bea...you are right. I honesty read so many PDF field studies that I sometime read them too quickly. But never the less kind of a neat read!

I hear you! I've been reading these dry, scientific papers for so long now that I've become quite used to 'translating' their long words and round-about way of putting things. They should all hire somebody to re-write these articles in 'normal' language for people like you and I -LOL.
