Shot without a flash so the true colors of the bird may not appear as the vast majority of the light in the understory has passed through a green leaf. I mostly use the flash inside the forest to fill in shadows, and since this shot has no shadows, I am happy with it.
Found inside the forest, and similar to the [Greenish Puffleg], but less green and more grey/drab. Male and female similar, but male is dark grey in front, while female is lighter ({hoary}). Note {rufous} rump and head can be hard too see in the field.
