A HISTORY OF NORTHAMPTONSHIRE 



202. Great Northern Diver. Colymbus glacialis, 



Linn. 



A rare winter visitor, usually keeping to the 

 sea, but occasionally coming inland to rivers 

 and large sheets of water. Three, at least, 

 have been obtained in Northants. 



203. Black-throated Diver. Co/ymbus arcticus, 



Linn. 



An occasional winter visitor, scarcer than 

 the last, but of much the same habits. One 

 was shot on Naseby reservoir on October 

 25th, 1881. 



204. Red-thro.ited Diver. Co/ymbus septen- 



trionalis, Linn. 



An occasional winter visitor under much 

 the same conditions as the last two species, but 

 decidedly more abundant than either, and 

 oftener seen on rivers. Obtained with us in 

 winter dress, it should be remembered that the 

 red throat is then not worn, being only a sum- 

 mer adornment, as are also the black throats of 

 the last two species. 



205. Great Crested Grebe. Podicipes crhtatus 



(Linn.). 



A resident, wandering about, more or less, 

 from autumn to spring, and breeding upon 

 several of the larger sheets of water in the 

 county, e.g. at Ravensthorpe, Naseby, Blather- 

 wycke, Deene, Canon's Ashby, and Byfield. 

 It is to be feared that the pike in these places 

 get most of the young birds. 



206. Red-necked Grebe. Podicipes griseigena 



(Boddaert). 



A winter visitor, uncommon, and usually 

 marine in its habits. I have occasionally met 

 with small parties on the north-east coast ; it 

 has once been obtained on Naseby reservoir, 

 on February 17th, 1876 [Lilford^ ii. 281), 

 and one was seen at Saddington reservoir in 

 March, 1899, by Mr. W. J. Horn. 



207. Slavonian or Horned Grebe. Podicipes 



auritus (Linn.). 



An occasional winter and spring visitor, 

 which has half a dozen times been obtained 

 on ponds and reservoirs in Northants, no 

 doubt on its way to or from Iceland, where 

 it breeds abundantly (see Lilford., ii. 282, 283). 



208. Eared Grebe. Podicipes nigricolUs 



(Brehm). 



A rare casual visitor, occurring indifferently 

 at any time of the year, but not known to 

 have bred in Britain. A pair were shot on 

 Daventry reservoir in 1869 [Lilford). 



209. Little Grebe or Dabchick. Podicipes 



fiuviatilis (Tunstall). 



Common and resident. A great skulker, 

 therefore little seen in summer when reeds 

 are thick. 



210. Storni-Petrel. Proce/laria pe/agica,L,'mn. 



A purely marine species, except during the 

 breeding season ; occasionally driven inland 

 by severe gales, and has two or three times 

 occurred in Northants. 



211. Leach's or Fork-tailed Petrel. Oceano- 



droma leucorrhoa (Vieillot). 



A much rarer species than the last, yet it 

 has been obtained four times in Northants 

 (see Lilford, ii. 255, 256). 



212. Manx Shearwater. Puffinus anglorum 



(Temminck). 



A pelagic species occasionally driven inland 

 by storms. Three or four have been obtained 

 in Northants {Lilford, ii. 250, 251). 



213. Fulmar. Fulmarus glacialis (Linn.), 



A marine species occasionally driven inland 

 by storms, whereof one specimen is recorded 

 as having occurred near Bainton on April 4th, 

 1 88 1 {Lilford, ii. 253, 254).
