STUBBS : THE CORNCRAKE IN ESSEX. 191 alarm note3 ; for it transpired afterwards that, at the very spot, the female was sitting on eggs, and may well have been disturbed by a rat or a weasel. When the field was cut late in June, Mr. A. H. Tozer went to the place and saw the nest ; and, the following day, his dog was very elaborately befooled by the artful mother, which, on two occasions, by simulated lameness, led the animal to the very extremity of the meadow. On the 24th June, the dog was unlucky enough to catch two of the nestlings, which were shown to me by Mr. Tozer. One Mas safely returned, but the other was injured and died, the skin being preserved as a specimen for the Essex Museum of Natural History. In life, it may be remarked, the eyes, beak, and feet of these nestlings were sooty black, the downy plumage being also black, glossed with brownish bronze. Mr. Christy makes the very reasonable suggestion that perhaps this family are the survivors of a local Essex race of Corncrakes. So far, the only evidence of disparity is that of voice, and at the moment I can find but few references to this subject in the literature of birds. My own notes, for Derby- shire and Lancashire, state clearly that "crake" is uttered about once a second. In Mr. T. A. Coward's Fauna of Cheshire (vol. i., p. 367), it is stated that the "disyllabic note is some- times uttered sixty times per minute." The note is, therefore, not the single crake, but the double crake-crek ; for this alone could be called disyllabic. My own remarks are clear that I myself count each of the paired syllables as a single note. At any rate, the 1914 Theydon Bois bird said "crake" 90 to the minute ; and, by 1917, it had reached 112, and was far too hurried to give the impression of disyllables. Northern birds, I ought to add, utter their notes in pairs ; and this is recognised in the iron combs used as calls by old-fashioned gunners, where a notch in one of the teeth assists the user in making every second crake about one fourth shorter than the rest. The disyllabic "crake-crek" is thus, on the Pennines, uttered thirty times a minute. I feel pretty confident (remembering my first exper- ience with this Essex bird) that, had I heard a similar cadence in Wales or Scotland (where I have often encountered the Corncrake), I must have noticed its dissimilarity to the birds of north-west England. 3 cf.
