Bat Falcon female (Falco rufigularis petoensis)

As I was photographing the feeding male, this much larger female came swooping low right past me. She then dive-bombed the male forcing him off his perch and displacing him on the same branch. Much loud Kestrel-like calling ensued. She seemed none too happy with her mate's refusal to share. Marital spat? Note the relatively smaller eyes, flatter head and the lack of ear-like projections on her head cf. the male. Also the rusty undertail coverts visible in this photo indicate she is an adult.
