122 THE ZOOLOGIST. 



whatever lake or marsh they were using. If they had been im- 

 mature one might have suspected them of being the produce of 

 somebody's pinioned birds, but from their appearance they 

 seemed to be adults. The great autumnal movement did not 

 commence in earnest until Sept. 18th, but when it came it was 

 far from being confined to Norfolk. In fact, the observations of 

 Mr. W. Eagle Clarke, taken on Fair Island (Ann. Scottish Nat. 

 Hist. 1906, p. 236), which is midway between the Orkney and 

 Shetland groups, point to a wave of migration reaching from 

 lat. 52° to lat. 59°. This extended front was chiefly made up of 

 small birds (Passeres), but in Norfolk other Orders among birds 

 were not unrepresented, as will be recorded further on. 



The rarities for the year, so far as they have been communi- 

 cated to the recorder, are : — January : Nyroca Duck (two) . April : 

 Stilt (?), Crane, Nyroca Duck (four). May: Ortolan Bunting, 

 Bluethroat, Nyroca. June: Sand Grouse (?). July: Pelican. 

 August : Purple Heron, Great Eeed- Warbler. September : Bed- 

 breasted Flycatchers, Glossy Ibis (four), Bed-crested Ducks 

 (fourteen). October: Bed-crested Duck. December: Whooper 

 Swans (about one hundred and fifty). 



As before, the letters "d. u." denote "date uncertain"; and 

 the figures following the direction of the wind are used in the 

 same sense as in the publications of the Meteorological Office — 

 force 2 is a gentle wind, force 3 a breeze, force 4 a high breeze, 

 and force 5 and 6 a gale. 



My register for the rainfall was 25'43 ; that of Mr. Knight, 

 which has been usually given, was 27*16. The effect on birds of 

 the arctic weather which set in on Dec. 24th was very disastrous; 

 very many perished. 



January. 



1st. — January, which opened with a sharp frost, brought a 

 rarity with it — the Nyroca Duck, which the Bev. M. C. Bird has 

 already alluded to (Zool. 1906, p. 75) ; while a still rarer one, if it 

 had not escaped — the Baikal Teal — was taken in Essex. 



5th. — A Water-Bail picked up at Tuddenham, with a Trout 

 3^- in. long sticking in its mouth, which is by nature a small one 

 (E. Gunn). About this time (d. u.) a Common Tern (immature) 

 was, as I learn from Mr. W. Clarke, picked up dead on the edge
