Small hawk/falcon in Mindo, Ecuador (1 Viewer)

[akjackson1]

I studied this bird (taken Feb 8) for a bit and realized all the raptors that somewhat resemble this bird have a lot of variation. Any suggestions on the ID? I'm thinking it's got to be one of the following:

Bicolored Hawk
Semicollared Hawk
Barred Forest-Falcon
Collared Forest-Falcon

 

[Butty]

I'd forget most of those because they don't look much like this bird at all. I'd guess bicolored hawk, immature (blackish crown, plain underparts, dusky tail, whitish hind-collar).
