Chestnut-necklaced Partridge

The chestnut-necklaced partridge is a medium-sized ground partridge about 26–32 cm long. Its brown upperparts are finely patterned, while a rich chestnut band forms a conspicuous necklace across the lower throat and upper breast; dark facial markings and pale spotting add contrast. The sexes are similar. Taxonomy and geographic limits within Tropicoperdix have shifted, so locality and vocal evidence are important when distinguishing regional forms (Wikipedia, general species account).

It is associated with lowland evergreen and secondary forest, where pairs or small groups walk beneath dense cover and forage through leaf litter for seeds, fallen fruit and invertebrates. Birds usually run when disturbed and make only short, explosive flights. The scientific spelling is commonly given as Tropicoperdix charltonii, while the site currently uses T. charltoni; this should be checked against the project's chosen bird taxonomy before any name change is made (Wikipedia, general species account).
