Personal Notes: Seen several times (along with several howler monkeys) in a central Belize lowland forest with a lot of blowdown from hurricane Richard and, sadly, a fair amount of illegal logging. We saw this species a second time in Arenal Hanging Gardens, a female seen sitting on a nest at the end of a long hole in the ground.

Compared to other honeycreepers in this area, Green Honeycreeper lacks striping on chest. Similar to Shining Honeycreeper but in the absence of seeing the distinguishing red legs, the lower elevation makes this most likely a Red-legged Honeycreeper.
