Table 1. Comparison of the breeding bird populations of Badby Wood, Oxfordshire (1946-1950) with that of part of St Thomas' Quarters, Epping Forest (1966-1969).

A B.T.O. survey of a 34 ha area of the Forest, in St. Thomas' Quarters, near the Wake Arms, between 1966 and 1969 may be compared with the figures obtained from a similar study of a slightly larger 40 ha pedunculate Oakwood in Oxfordshire between 1946 and 1950 (Simms, 1971) (Table 1). Against the 36 species breeding in the Oxfordshire wood, 27 bred in St. Thomas' Quarters and 22 of them were common to both localities. The Epping site had 5 birds not recorded for the Oxfordshire locality and the eleven Oxfordshire birds that were not listed for St. Thomas' Quarters are known to breed in adjacent parts of the Forest, suggesting that the bird communities of the two areas to be broadly comparable. Irvine (1977) studied the breeding bird community of an 8 ha area of the New Forest. The site is part of the "Ancient and Ornamental" woodlands, and is dominated by beech, including a number of ancient pollards, but with dense stands of holly as well as glades of bracken (Pteridium aquilinum), heather (Calluna vulgaris) and bilberry (Vaccinium myrtillus) being invaded by birch 10
