146 THE BIRDS OF ESSEX. Family CAPRIMULGIDAE. Nightjar: Caprimulgus europaeus. Locally, "Night Hawk' (Orsett). A regular summer visitor, but very sparingly distributed, except in a few spots which are peculiarly suited to its habits, as Epping Forest, Ongar Park Wood, and the woods and commons round Danbury, Tiptree, War- ley, and elsewhere In most parts of the county it is seen occasionally when on migration. It usually arrives about the middle of May, and de- parts in September. Albin says (3. i. 10), "I have seen them on Epping Forest and divers other places." Mr. Buxton says (47. 93) they are " frequently seen during summer in the Forest, where they breed." "J. H." records (39. Jan. 13,1883) that in 1883 he found a couple of nests in the Forest, and I found a nest near Ambresbury Banks in 1870. I also saw a nest—or rather eggs—in Ongar Park Wood in 1877. Mr. G. Walford wrote in 1838 : This bird " appears to have been unusually numerous in this county during the last season, several having been sent tome to be preserved." (19. 74). According to King (20) it is ' rather rare " round Sudbury. At Harwich it is fairly common and breeds (Kerry). Round Orsett, where there is very little woodland, it is "not common " (Sackett), but Dr, Laver speaks of it as "common in both the Colchester and Paglesham districts." Mr, Clarke states (24) that one or two were killed in most years round Walden, where in 1880 I knew of two nests, although I know the bird to be decidedly uncommon there, except round Chesterford, where Mr. Brewis tells me it breeds commonly. Mr. W. C. Emson of Littlebury also in- forms me that they breed there every year. It abounds among the woods and commons round Danbury and Little Baddow, and on Tiptree Heath. My cousin, Mr. R. W. Christy, saw a specimen in Nightingale's Wood, Roxwell, on several different days during frosty weather in the winter of 1881-82. This is a very remarkable occurrence, though it has on other occasions been known to remain till November. Mr. Fitch has once found the eggs in Hazeleigh Hall Wood. specimen (29. Nov. 23 & 30, 1878) which is said to have been preserved by Morris, a bird-stuffer, of Low Leyton, Essex, but nothing further is known about it. Ambrose of Colchester, through whose hands the specimen passed, did not believe it had been set up from a skin.
