a. S ad. Luiconia, Ajo. April 29, 1909. 



Irides dark brown; bill, legs, and toes black. 



This specimen is in full plumage and is just completing 

 the moult on the head. 



Several of these birds were seen on the 29th of April, but 

 were so wild that I could only secure one. 



A pair or so are always to be seen at Luiconia on the out- 

 skirts of the rough grass country, but I am by no means 

 sure that it breeds there.
