they very rarely occur, and the normal clutch of S. dougalli 

 consists of two eggs, laid apparently at an interval of two or 

 three days. — F. C. R. J. 



An examination of 76 nests of the Arctic Tern in one colony 

 during this season gave the following figures: — 11 contained 



1 egg each, 4 contained 3 eggs, and 61, or over 80 per cent., 



2 eggs. On the other hand at another colony (only a very 

 small proportion of the nests being found) no less than 8 out 

 of 13 contained 3 eggs.— N. F. T .] 



ARCTIC TERNS FEEDING ON CRANE AND 

 MAY FLIES. 



A curious incident happened a few days ago whilst fly fishing 

 on Lough Melvin, co. Leitrim, for the famous gillaroo. We 

 had landed on Inishtemple Island to lunch and during the 

 interval I took the opportunity of visiting a Tern colony 

 there ; the young in most cases were hatched and a good 

 number full^ fledged, these I noticed were being fed not 

 with sand eels (the sea being five miles distant) but with 

 large crane flies, there being enormous quantities of these 

 insects among rushes in the centre of the island. 



On resuming fishing my brother, who was using a blow fine 

 with bowh a greendrake and crane fly on the hook, and whilst 

 drifting past the spot on which the Terns were nesting, we 

 were surprised to see an adult Arctic Tern dash down, seize 

 the bait, and on rising again get caught and entangled in the 

 fine hue, the hook entering under the wing. It was an easy 

 matter to reel the bird in, and putting a ring on one of its legs 

 we let it go again. A second one was caught in a similar 

 waTyr a few minutes later, and doubtless had we been longer 

 oii the drift we should have hooked many others. The 

 greendrake as well as the May fly were out in large quantities 

 on the water and the Terns were feeding on these as well as 

 the crane flies.

BRUNNICH'S GUILLEMOT IN YORKSHIRE. 



On June 27th last I saw on the Bempton Cliffs an undoubted 

 example of Briinnich's Guillemot (Una bruennichi). I saw 

 this bird several times as it always returned to the same ledge 

 in company with a Common Guillemot, and it was not more 

 than forty or fifty feet below me, so that I could discern every 

 detail with the naked eye easily, and with my Zeiss glass I
