Observation details
This is well established bird hide and my count is conservative. Numbers very larger. As I had an opportunity to see a large number of Crested Partridges (Rollulus rouloul) at Trusmadi, I attempted to see if I could identify juvenile to adult progress. The collage shows an attempt. Individual images of the youngest juveniles are also shared below. Collage bottom row images are of an adult male and female. Collage middle row images are of immature male and female. Collage top left panel is a downy chick which is mahogany-brown, paler in the breast with a dark streak on the head and behind the eye. Collage top right panel is an older chick (poult), all of which resemble the female but are not yet able to differentiate as male or female.
