I agree - I really like this photo, Semioptera. I like how you caught it at just the right moment so that the birds seem like they're almost mirroring each other.
I've only ever seen the tawny frogmouths sitting perfectly still. Was this one still as the bird-of-paradise checked him/her out?
Thanks Korhoen, AnaheimZoo. @AnaheimZoo: This Tawnyfrog stayed still in his place eventhough the BOP bothers him. Female Raggiana only stayed for a while checking the frogmouth, before she chased other birds in the exhibit
