CRANE-FLIES and Leather-jackets are accounted for in vast numbers by Lapwing, Rook, Starlings, Thrushes, Corncrake, Wren, House-Sparrow, Yellow-Iminmer and Curlew. Professor Newstead records that during a plague of Crane-flies the remains of 400, with 1,600 eggs, were found in one of the pellets (representing probably one meal) of a Black-headed Gull. " If this were a single Gull it would be accountable for the enormous number of 4,000 Crane-flies per day, making an aggregate of 28,000 per week."—Birds, Insects and Crops (The Royal I Society for the Protection of Birds, 1918)
