202. Great Crested Grebe. Podiceps cristatus (Linn.).
As long ago as 1744 it was shot by Mr. van Hatten's keeper about a mile and a half from Dinton Hall. Occasionally obtained on the waters of the county. It breeds in some numbers on the Halton (Weston Turville) reservoirs, as well as on the Tring reservoirs. W. Rothschild saw a pair with young in May 1901, in Stowe Park near Buckingham.
203. Red-necked Grebe. Podiceps griseigena (Boddaert).
A ' fine specimen,' ' in winter plumage,' was shot at Sanderton near Risborough, on October 10, 1848.
204. Slavonian Grebe. Podiceps auritus (Linn.).
One was shot by Mr. Heneage Cocks' gardener at Great Marlow in the ' sixties.' Two were shot on Halton reservoir between 1874 and 1880. These were identified by the Rev. H. Harpur Crewe and seen by W. Rothschild in a keeper's possession, but we do not know where they are at the present moment. Mr. Kennedy mentions a specimen killed upon the Thames at Datchet in December 1867, and he heard of another near Eton about the same time.
205. Eared Grebe. Podiceps nigricollis (Brhem).
This bird was obtained on the Tring reservoirs in 1846 or 1847. The specimens were identified by W. Rothschild, who saw them in the hands of a keeper, but we do not know where they are now. The statement that it was found breeding on Tring reser- voirs (Kennedy, p. 210) must be erroneous. In the MS. at Dinton Hall a specimen shot on November 20, 1776, is figured.
206. Little Grebe or Dabchick. Podiceps fluviatilis (Tunstall).
A very common bird, breeding on many reservoirs and ponds of the county.
207. Storm-Petrel. Procellaria pelagica, Linn.
In 1865 an example was shot and pre- served near Burnham by a man named Hebbs. In October 1859, after the dreadful gale that wrecked the Royal Charter, one was found lying dead, but still warm, upon the road opposite the Priory, Burnham. On January 21, 1868, one was knocked down near Wy- combe (Kennedy). About the middle of October 1877, one (said to belong to this species) was seen flying against a mill at High Wycombe, but recovered and flew away. There had been strong gales the previous days (D. Thurlow, Field, 1877, Oct. 20, p. 441). In November 1880 a storm-petrel was picked up near Wendover (Clark Kennedy, Zoologist, 1881, p. 68).
208. Leach's Fork-tailed Petrel. Oceanodroma leucorrhoa (Vieillot).
After the strong gale in the summer of 1847 or 1848 a man named William Hibbs caught a specimen at Eton. On November 1, 1859, during the storm that brought a storm petrel to the county, a gardener of Lord Chesham found a fork-tailed petrel in the park at Latimer, which was examined by Mr. Burgess (Clark Kennedy, p. 218).
