VARIOUS NOTES ON BIRDS OF ESSEX. 25 Mr. J. B. Nichols. I had the opportunity of examining the specimen before it was sold on 11th June, 1929. It was stated to have been shot by Mr. Eedle. This species can now be fully admitted to the Essex list. Coot (Fulica a. atra L.) . A party of about eighty was seen on the tidal water of the Blackwater, near Bradwell, on 1st February, 1930. Migration.—Mr. L. S. Harley informs me that on the evening of 18th September, 1929, he saw a large flock of birds perched on the high-tension power lines between Pitsea Station and Bowers Gifford Church. They appeared to be either Martins or Swallows, but he could not identify them from the train. The wires were black with the birds, which occupied all six lines for over 150 yards, and it was estimated that the flock must have contained about 10,000 birds. Mr. P. W. Horn observed a considerable movement at Southend on 31st October, 1929, between 9 a.m. and 3 p.m. Rooks were mostly in evidence, small parties of from six to thirty being noticed. Small parties of Skylarks, a few Linnets, several parties of female Chaffinches, and one party of seven Song Thrushes, were also noted. The birds were coming across the estuary from the direction of the Kent coast, the wind being N.E. FELSTED DECOY. Mr. A. Hills has published an article in the Essex Review of October, 1929, in which he expresses the opinion that the late Mr. Miller Christy was mistaken in his view that a decoy had existed in this locality. Although it may yet be proved that Mr. Christy made an error I am unconvinced by the arguments adduced by Mr. Hills. The chief point that he makes is that the ponds referred to in his article are described in the Historical Monuments as Mill Ponds. If Mr. Christy based his conclusions on the existence of these ponds nothing more need have been said, but I have no knowledge that he did so. Some of the statements used by Mr. Hills to support his opinion call for comment. He has assumed that all decoys had pipes, but this is not so, for Sir Ralph Payne-Gallwey shows that there were types without them. The fact that Mr. Hills has "never been able to find anything . . . remotely resembling a decoy in shape or character" does not destroy Mr. Christy's argument.
