 Redshanks {Tringa erythropus) are recorded from Morton 

 Loch (N. Fife) on 30th August, and one there on 5th and 

 8th September (1. 1916, 287), these being the first records 

 of this Wader for Tay. A Black-tailed Godwit {Limosa 

 limosa) was seen near Arbroath on 7th September (Douglas 

 Hunter). Two Black Terns {Hydrochelidon nigra nigra) were 

 seen flying inland near Port William (Luce Bay) on 

 20th May (J. G. Gordon), and Little Gulls {Lams minutus),

 {Pagophila eburnea) ; adult males are recorded from Mallaig

Extension of Breeding Range. 



There are two extensions of breeding range to record for 

 1916. Great Crested Grebes bred for the first time on 

 Kilconquhar Loch (E. Fife), two and possibly three pairs 

 and young being seen several times during the summer 

 (1. 19 16, 264). This is a further spread of a species which 

 has been increasing of late years as a breeding bird in 

 Scotland. 



On 27th May a Black-headed Gull's nest was found on 

 Sule Skerry, the " first known to breed there." In Studies of 

 Bird Migration, ii., p. 302, Black-headed Gulls are said, on 

 the authority of Mr Tomison, to visit the island " for a day 

 or two in the middle of summer."
