262 THE ZOOLOGIST. 



was even darker than the one just quoted, and the other two 

 almost the same as the lighter kind described ; these I did not 

 take, and have since regretted it, as it would have tended the 

 better to substantiate the occurrence of these two birds nesting 

 together. I do not altogether place too much reliance on the 

 fisherman's statement, because I know very well that their in- 

 formation, though not actually perhaps fickle, is at all events 

 sometimes a little inaccurate, and I should be very happy to hear 

 some other observer's opinion as to whether this social and 

 economical instinct has been noted in these two Gulls before, or 

 whether it is that I have fallen into one of the many traps pro- 

 vided by the eccentricities of Nature for her youthful students. 



The following is the list of birds, with notes on same, com- 

 piled during my visit : — 



Mistle-Thrush (Tardus viscivorus). — Not so common as the next 

 named, but met with several times singing from the tree-tops in various 

 parts of the island. Found no nest of this species. 



Song-Thrush (T. musicus). —Well distributed throughout the island, 

 but always keeping well away from the sea. One individual sang from 

 the trees opposite our windows punctually at daybreak, and again at 

 night, right up to 8.45 p.m. on one or two occasions. 



Blackbird (T. merula). — Quite one of the commonest birds. Found 

 nests with eggs in various stages of incubation. On May 24th a nest 

 of four young ones in a furze-bush. 



Whinchat (Pratincola rubetra). — Saw only one individual, and did 

 not see the nest. 



Stonechat (P. rubicola). — This bird was quite abundant among the 

 gorse on the western coast, and again in Little Sark, but was less 

 noticeable in other localities which seemed to be equally suitable. 



Robin (Erithacus rubecula). — Common. Saw two or three broods 

 of young ones, and found deserted nest with five eggs in hollow in 

 grassy bank at side of road near Beau-regard. 



Whitethroat (Sylvia cinerea). — Rather rare. Did not see this 

 species many times. 



Lesser Whitethroat (S. curruca). — I fancy I saw this bird once 

 near the Seigneurie grounds, but am not quite sure. 



Garden Warbler (5. hortensis). — Once heard one singing from the 

 tangle at the side of road running through the Seigneurie grounds, 

 and also saw one fidgeting about in brambles in the same neighbour-
