It is very common to hear the loud calls of these birds during early mornings and at dusk. They constantly move around foraging the forest floor for grains, seeds and tiny insects. The Grey Junglefowl get easily spooked at the slightest disturbance. This coupled with the fact that they rarely standstill make them a pretty challenging subject to photograph.
Here is a collection of images of this very restless bird. All images are taken at 600mm focal length with the D300, 300mm f2.8 lens mounted with the 2x TC.
