PTBEOCLID^ PTEEOCLES 187 



It is found during tlie day singly or in pairs scattered over the 

 grassy veld in search of seeds and berries which form its food; 

 in the morning and evening it resorts in large numbers, often 

 in company with the other sandgrouse, to watering places, circling 

 round high up in the air and descending very suddenly with a dash. 

 Its note is less shrill and piping than that of the other species. 

 The eggs are described by Layard as pale dull greenish-brown 

 spotted with light brown and indistinct purple, and further spotted 

 with dark brown. Eriksson states that three eggs of this bird 

 were brought to him by one of his hunters ; they were laid on the 

 bare sand in a small depression.
