530 On the Ornithology of Blackburn 



20. Larus marimis. Greater black-backed Gull. Though not exact- 

 ly common, these birds are generally to be met with on the coast. 

 Last week, at Blackpool, I saw fourteen together in a flock ; be- 

 ing without a gun they suffered me to approach very near. Out 

 of the fourteen only three were in the adult plumage. When fly- 

 ing they presented a most enormous expanse of wing. 



21. Larus glaucus. Glaucous Gull. Very rare. This is the most 



scarce of all the gulls proper. 

 Sub-gen. 3, Chroicocephalus. 



22. Chroicocephalus rudibundus. Black-headed and red-legged Gull. 

 Common. Dr. Moore observes that in Devonshire this bird is ve- 

 ry scarce in the summer plumage ; now on our coasts the reverse 

 obtains, and they are generally observed in the summer plumage, 

 that is, with the black hood. On my recent visit to Blackpool I 

 observed numbers of them in this state of plumage ; I suppose 

 this is owing to their breeding somewhere about these parts. It 

 is well known that they do breed on the rocky coast of Wales to 

 the south, and on the isle of Walney to the north, as also in the 

 isle of Man. This is one of the great advantages of local Faunce, 

 that the habits and haunts of birds can be observed in so many 

 points simultaneously. 



Gen. Sterna. 



23. Sterna Anglica. Gull-billed Tern. Very rare. I have one spe- 



cimen shot at Blackpool in the summer of 1832. 



24. Sterna cantiaca. Sandwich Tern. Equally rare with S. Anglica. 



25. Sterna arctica. Arctic Tern. Frequently met with on our coasts 

 but generally confounded with Sterna marina. I have seen se- 

 veral specimens shot at or near Blackpool ; and until the publi- 

 cation of Gould's beautiful plate of this bird, I fell into the com- 

 mon error of confounding it with the common tern, but can now 

 easily make the distinction. 



26. Sterna marina. Great Tern or Common Tern. Abundant. 



27. Sterna minuta. Little Tern. Very common. 



28. Sterna nigra. Black Tern. Rare. I have one specimen shot in 

 the spring of 1832, on a bleach-works lodge. 



Fam. iii. — Totipalmata. 

 Gen. Phalacrororax. 



29. Phalacrororax Carlo. Cormorant. Often met with on the coast. 

 Gen. Sula. 



30. Sula bassana. Gannet. Very rare ; occasionally shot in the estu- 

 ary of the Ribble after severe storms. In the spring of 1837 one 

 was taken in a rabbit-hole, near Lytham, into which it ran for 

 shelter on being pursued. 



Fam. ir. — Lamellirostres. 

 Gen. Mergus. 



31. Mergus Merganser. Goosander. Though not common it has seve- 



ral times been taken on the Ribble and Hodder. I have a fine spe- 

 cimen of the male shot some years ago on the Hodder, in Bowland. 



32. Mergus serrator. Red-breasted Merganser. Very rare. For the 



capture of the only one that I ever met with, vide the * Magazine 

 of Natural History,' vol. ii. n. s. page 333. 



33. Mergus albellus. Smew. Rare. For the capture of two vide the 



'Magazine of Natural History,' vol. ii. n. s. page 331. 

 Gen. Fuligula. 



34. Fuligula ferina. Pochard. Obtained occasionally on the coast.
