OTIDIDAE—BUSTARDS. 229 posed it to be standing, then looked through cautiously and had a fine view of it. It was about 150 yards off, and appeared to be an old bird in perfect plumage. Of course it was no use firing at it at such a distance, but I thought if I went on a few yards further, and crawled through a gap, and ran in upon it, I might get within shot before it rose, or that it might fly towards me. But while I was thinking of this it took wing, and flew right away from me towards some salt marshes, where it pitched again. I followed to the bank, and, upon looking over, saw it about a mile off, standing on some bare mud. Soon after it was fired at by some one from a boat which was in a creek near at hand ; and it then flew off to the westward, and I lost sight of it." After this, I received several further reports of the bird, which was repeatedly seen on the marshes and mud-flats between Walton-on-the-Naze and Harwich for several weeks after. On Oct. 14th, Mr. Kerry reported its having been seen there in company with some Herons. Family OTIDIDAE. Great Bustard : Otis tarda. There can be no doubt that this interesting species was once resident in Essex, as in most other parts of England, although now never seen, except as a rare and accidental straggler. It was probably never abundant in this county, which has few of those wide, open, uncultivated districts fre- quented by the bird. However, on the extensive downs around Heydon and Chrishall, in the ex- treme north-eastern corner of the county, which are exactly suited to its habits, it was probably once fairly common—indeed, we have actual printed evidence of the fact, for in Addison's Spectator for March 4th, 1712 (No. ccxvii.), occurs the follow- ing advertisement, to which Yarrell's attention was drawn (14. i. ix.) by Mr. Joseph Clarke :— " Heyden, in Essex, near Walden and Royston.
