Shadows and angle made the identification confusing and there was disagreement between our guides at the time. My current thinking is that this is an immature male Black-tailed Trogon, based on the grayish throat combined with overall green upperparts. Blue-crowned is eliminated by bill and crown color Another candidate is Collared Trogon which I believe is eliminated by the the broad-based tail which tapers towards a narrower the tip. Corrections always welcome.
