This little Wader has much the same actions as the Curlew- 

 Sandpiper [Tringa subarquata), for which species I at first 

 mistook it. Like that bird it wades deep into the water — in 

 fact, until the water flows over the back of its neck.

This species was observed in nearly every locality visited, 

 but is apparently only a winter visitor in the Ajo district, 

 as I have not heard of it breeding there. At that season 

 it congregates in flocks of several liundred individuals, and 

 frequents both the coast and inland Avaters, where it is usually 

 seen hawking over the water with slow regular flight, 

 presenting to ray mind a rather ungainly appearance.
