NOTES. 225 



the courageous little hen again returned and administered to 

 the youngster another green caterpillar, keeping one eye on 

 me meanwhile. I then put the young bird back into the nest 

 after first fastening a ring on one leg. This business occupied 

 some minutes, during which the mother crept round and round 

 me, now fluttering with apparently 'broken wing, now creep- 



ing in and out of the rough tangle of sedge and grass, all the 

 time uttering a curious cry which resembled that of a weasel. 

 The male bird, which diligently took his turn in feeding 

 the young, occasionally showed great displeasure at my 

 presence by displaying his tail-feathers as shown in the 

 accompanying photograph.

BLUE-HEADED WAGTAIL IN ESSEX. 

 On September 12th, 1909, I saw six Blue-headed Wagtails 

 (Motacilla flava) in the neighbourhood of Southminster, 

 Essex. Two of them were adults and four were young birds.
