I have been observing the Fork-tailed Woodnymph for three years now. A common hummingbird at Kabalebo. He/she is not shy/afraid for other birds or humans, they are rather dominant and defensive. They sip nectar from blossoming flowers, sugar water from feeders in the open and in the interior.
I have witnessed many times that the male started to 'complain' the moment you touch his tree.
I have taken this picture of the male near his tree and as you can see, he is not afraid or shy, but is rather curious.
When there is enough sunlight you can spot the wonderful colors on the male his neck and chest. If not, it looks like he has dark/black colors.
The female looks less 'colorful' since she has to incubates the eggs all by herself and a camouflage color always comes in handy.
In 2012 I was lucky to 'spot' a nest of this hummingbird, about 2.5 meters above the ground on a branch.
