Käyttäjän monroyfotografo tunnistukset

Observed at Kiraikai lodge near Filandia, Colombia. My guide called this a Mountain Velvetbreast in the field. In reviewing pictures much later, I don't think that is correct, but I cannot find a species that matches this exactly. My best guess is a Green Hermit, perhaps a young bird in transition plumage? Any help would be appreciated!
