200 THE ESSEX NATURALIST They must have had a good breeding season, for by the late summer of 1948 they were completely re-established, in spite of the way they are perse- cuted here by everyone with a gun. RED-BACKED SHRIKE While never common, before the war one or two could be seen every summer. Since 1945 I have seen only one. COMMON AND RED-LEGGED PARTRIDGE Both species have increased considerably. SNIPE Fairly common. Before the war it was very common, but has decreased a good deal, undoubtedly owing to the drying up and draining of wet land. LONG-TAILED TIT Here, at any rate, this species has not suffered from the 1946-7 winter as much as one might expect, in fact, there seem to be as many around as before. WHIMBREL This species, as a passage migrant, seems to be more common than before. Reason unknown to me. Little flocks of four or five birds fly over saltings and inland regularly between April and November. I. Rainier. The Wood-lark and other birds at Warley While I have been stationed at Warley Barracks I have been much im- pressed by the wealth of bird life in a small area. During the early part of the nesting season of 1949 I was able to map many nesting sites and to spend considerable time watching some of the birds, particularly a nesting pair of Wood-Larks (Lullula arborea). Five nests of this species were found within the barracks area. I first saw one pair of the birds on April 13th when I watched the hen feeding. She walked along the edge of a drive carrying a grub in her beak, she then put the grub down while she searched for more in a tuft of grass. Before passing on to another tuft she picked up the first grub and this procedure was repeated until five or six grubs had been col- lected. The cock was singing from April 13th to April 29th. He did not sing and was rarely seen while the hen was sitting. His song was again heard on May 15th, 16th and 17th but only for a short period after dawn. He did not sing again until after the young had left the nest. The breeding time- table of this pair was as follows : April 23rd. Hen building nest with dry grass collected from a distance of about three feet. April 28th. Nest completed. April 29th—May 3rd. Neither bird seen. May 3rd. First egg laid. Additional eggs were laid on each suc- ceeding day, one being taken on May 6th. No incubation took place during the laying period and the birds left the area after each egg was laid. May 8th. Incubation commenced. I was away between May 18th and 22nd. On the 23rd I found four young in the nest. While the young were being fed the parents always landed some five feet from the nest and approached it by a well worn path and a small tunnel. When leaving they flew straight from the nest over my hide. The excreta was removed from the nest in a manner similar to that of the Hedge-Sparrow.
