LIST OF NOnFOLK BIRDS.

233. Puffin {^Fratercula arclica). 
'J'he I’ulHn is certainly not a coimuon bird, at least near tlio 
shore. Occasionally an example is picked up inland, and after 
continued rough weather, dead ones are sometimes found on the 
beach, both adult and immature. Six have occurred at different 
times in March, and several in May, but after that they have left 
us for their breeding places, the nearest of which is at I'lamborough 
Head: though some have been seen by Mr. Southwell in Yarmouth 
“ roads ” in summer. On the whole they are not nearly so common 
as might be expected, remembering the great numbers Avhich now 
resort annually to the bird-nursery just named. — O, 
234. Great J4ortiiern Diver {Colymbus glacialis). 
Is not uncommon at sea in the winter, but has not occurred in 
the breeding plumage as far as we can ascertain. Mr. Stevenson 
has recorded one as far inland as 'J’oniston Mere, near Watton 
(Trans. Norfolk and Norwich Nat. Soc. vol. ii. p. 210), and 
!Mr. Gunn another on Surlingham I’road (‘Naturalist,’ 18G7, 
p. 83). 
235. Black-tiiroatki) Diver {Colymbus arcticus). 
Not much rarer than the Great Northern Diver, and some have 
been shot which had in great part assumed breeding plumage ; but 
no example has ever been obtained in (luitc complete attire. 
23G. Ped-tiiroated Diver {Colymbus septeutrionalis). 
!Morc frequent than cither of the preceding, and is found at sea 
at most seasons of the year. In October, 1880, an extraordinary 
niigi-ation was witnessed off Cley by the Messrs. Power : the 
Divers were a quarter of a mile from the shore, and were going 
south-east in a constant stream for nearly four hours (Trans. Norfolk 
and Norwich Nat. Soc. vol. iii. p. 349). One obtained is said to 
have had a perfect red throat, but I have never seen a Norfolk one 
really in complete plumage. Mr. Gunn informs me that six were 
sent him to be stuffed in October, 18G5, killed in the county, all 
in nearly fidl breeding attire : some particulars of their plumage 
are given by Mr. Stevenson (‘Zoologist,’ 18GG, p. 85), and by 
Mr. Gunn in ‘The Naturalist’ (ii. 297). In a state of change it 
has been shot more frequently. — G.
