404 Mr. H. Durnford's Notes on the 



Tringa fuscicollis. 



Resident. Very common in the valleys of both the Sengel 

 and the Sengelen, and seen always in flocks. 



Calidris arenaria. 



I did not observe this species at Chupat during my last 

 visit ; neither did I see it during my journey to Lake Colguape. 

 I shot two out of a flock at Tombo Point on the 30th De- 

 cember. 



*Gambetta flavipbs. 



Not observed at Chupat during my last visit. Seen occa- 

 sionally on the Sengel. 



*LlMOSA HUDSONICA. 



Not observed at Chupat during my last visit, or during our 

 expedition to Lake Colguape. 



NUMENIUS BOREALIS. 



From the 8th to the 10th October large migratory flocks 

 passed the Chupat valley, flying south. They made a very 

 short stay in the valley, but long enough to enable me to 

 secure two examples. Not seen again. 



Iris wood-brown ; beak black ; legs and feet dark slate- 

 colour. 



^Sterna hirundinacea. 



Resident. A few observed about Lake Colguape, and sub- 

 sequently seen on the Sengel. There is a large ternery of 

 this species on Tombo Point. I was prepared when I visited 

 this place in December to see a considerable quantity of birds ; 

 but the number that met my eyes fairly staggered me. These 

 nests cover an area about 150 yards square. Allowing three 

 nests and five eggs for every square yard (a very moderate 

 computation, it being difficult to walk without treading on 

 the eggs) , we arrive at the extraordinary number of 67,500 

 nests, 135,000 birds, and 112,500 eggs; and, wonderful as 

 these figures may appear, I feel sure that I have rather under- 

 stated than overstated the numbers. The nests were mere 

 hollows in the fine gravel or shingle, and contained one, two, 

 and sometimes three eggs. The latter generally have the
