109 NOTES ON CERTAIN BREEDING HABITS OF THE SNIPE. By FREDK. J. STUBBS. [Read 30th October 1915.] DURING the past few years, I have found the Common Snipe to be fairly abundant as a breeding species in the eastern portion of Essex, and have taken the opportunity of checking and extending previous observations on the species, made in other parts of Great Britain. The most remarkable contribution to our knowledge of the bird and its habits has been described already in the Zoologist (1912, p. 196-177), but may perhaps be mentioned in these pages. On 2nd May 1912, in a large marshy pasture near Passingford Bridge, I watched a Snipe amusing itself by shooting along for many yards through the air, on outspread wings, back down- wards. This extraordinary manoeuvre was repeated again and again. Subsequently, I observed the same bird going through the evolutions of "drumming," but taking the usual plunge back downwards. In the next number of the Zoologist, confirmation came from three naturalists, Messrs. H. Eliot Howard, J. A. Harvie-Brown, and Julian S. Huxley, who had, independently, observed the same curious habit. Since that date, I have observed this reversed plunging of a bird high in the air on several occasions, but it has not been my fortune to see again clearly the strange upside-down horizontal flight. So far as I know, this last-noticed habit had not been recorded previously for any bird; but, from an article on the birds of Anglesea (Zoologist, 1904), two good ornithologists, Messrs. T. A. Coward and C. Oldham, appear to have seen the proceeding, although they failed to notice whether or not the performer was upside down. The Snipe is a most difficult bird to observe, but I have no doubt that its acrobatic habits are frequently indulged, and are well worth patient watching. The "drumming" of the Snipe is, I suggest, a problem that is still unsolved. Although sometimes audible at the distance of a mile, and at every hour of day and night in spring, and conspicuous in districts where the bird breeds, I have not yet questioned anyone who had unaided first observed the
