The range of the Bearded Long-tailed Partridge appears to be limited to the 

 highland forests of Vera Cruz. It is a rarer bird than D. macrurus, and nothing has 

 been recorded respecting its habits.

This Partridge is easily recognized from all the other members of the genus by its 

 white forehead and throat. It inhabits the thick forests of the highlands of Guatemala 

 and Costa Eica. According to von Frantzius, D. leucoplirys is known in the latter 

 country as the " Chirascua " ^, on account of ^ its peculiar cry, which is heard before 

 sunset. The bird is much sought after on account of the excellence of its flesh, but is 

 difficult to shoot, being extremely wild.
