" Perdiz" (Spanish name). 



Tlie Perdiz is common in most parts of Yucatan, and very abun- 

 dant in the east. Its flesh is highly prized for food, being very 

 fine and savoury. In the dry season this bird may often be seen in 

 great numbers drinking water at the aguadas, and along the roadsides 

 in the heat of the day, where it is easily shot. It is the sport of 

 the boys of the ranches to go out at 4 p.m. with stones to kill 

 Perdizes ; and those who aim well rarely return unrewarded. It is 

 never seen upon the trees, but is a good runner, rarely taking wing, 

 except when hard pressed. Its song is a single, loud, short, fluie-like 

 whistle, uttered at intervals of one or two minutes in the morning 

 and evening. This bird is found domesticated in many houses ; it is 

 said to rid the premises of the dreaded Alacranes (scorpions).
