This is a little gem of a movie that deftly combines beautiful photography with an touching story line that gains depth as the movie progresses. The comic acting of the parrots and Mark Bittners amusing narrative keep the film from total chickflickness. Fun and touching, what more do you want. And, oh yeah, it's non-fiction. Great ending!
I guess the only film that comes to mind to compare it to is Winged Migration, a big hit film (for an indy) about birds. Parrots has some great footage of the birds in question, but none of that flying with the flock sensation thatt Winged had. But what Parrots has, of course, is humanity. The relation of Mark to the birds is central to the films arc. The film also addresses the issue of humanities impact on the environment and the natural vs unnatural setting for the parrots.
Ultimately it decides, and I agree, we've changed the environment of urban areas irretrievably so let's not pretend otherwise.
