A very common resident in tlie Ajo district. The nest is 
a slight hollow in the ground, sometimes lined with a few 
bits of sticks or rubbish, and four eggs form the complete 
clutch. 
Thirty-six eggs were brought home ; the ground-colour 
varies from bright buff to clear olive, and they measure : 
axis 1*7 to 2’0in., diam. 1*27 to 1*37.

All these specimens are in winter plumage, and are still 
moulting. 
The American Golden Plover is very plentiful throughout 
the summer months, and frequents, often in large flocks, 
both the open grass-land and the edges of the lagoons. 
I have not observed it during the winter.
