38 THE ESSEX NATURALIST A similar observation is recorded from Loughton. A resident, visiting her poultry-run in February, 1946, surprised a sparrow-hawk therein and managed to catch it, but the bird soon died. P. Thompson. House sparrows stripping lime twigs. On 26th March, 1946, we noticed that a pair of house sparrows were taking the bark from a branch of a tree in a front garden. The tree is the common lime; about 2ft. 6in. had been stripped by 30th March. On 1st April a second branch was attacked ; by 30th July all work appeared to be finished and the branches were examined more closely. They did not appear to have been previously diseased or damaged. The two branches completely cleared of bark each measured 6ft. 6in. long by fin. diam. I estimate that a total of over 170 sq. in. of bark had been removed from the two branches. There may have been more than one pair of birds at work—circumstances did not permit of a more accurate observation. Richard Ward. Rare birds near Colchester, In April, 1946, a night heron visited the South Essex Waterworks reservoir near Colchester, where I was able to examine it through glasses and make certain of its identity. In October, 1946, I had a good view of a great grey shrike which was sitting on a telegraph wire on Mersea Island. I am familiar with both these birds abroad. Another rare bird which visited the reservoir during November, 1946, was a bittern ; it was unfortunately shot by a person who knew no better and I have its skin in my possession. C. G. Mangles, Lt.-Col. Fallow Buck at Parndon. During the summer of 1945 a male fallow deer, believed to have strayed from Epping Forest, frequented the Parndon district. G. Dent. There are (October, 1946) a number of fallow deer in the woods about Aimes Green. Deer straying from the Epping Forest herd must be less frequently disturbed in some of the larger woods and may breed there. It would be interesting to have details from those who know of such occurrences. C. B. Pratt. Seal at Southend. A seal was observed from the end of Southend Pier at high tide about midday on 2nd May, 1946. For over an hour it appeared at intervals of 10-15 minutes, remaining on the surface usually about two minutes. When first seen it was within 30-35 yards of the pier-head and, during the period we watched it, was never more than 200 yards away. It appeared to be interested in the onlookers, who, with almost complete unanimity, described it as a "porpoise"! G. H. Greaves. BOOK NOTICE The Story of the Parish Church of Loughton, Essex. By Percy Thompson. It is always pleasant to find a little book providing, in easily read form, an account of the history of one of our parish churches. When, as so often happens, the present building is a comparatively modern one which has replaced an earlier parish church, such an account written by one well versed in the history of the church and its predecessor is more than ever necessary to help one visualise the generations of faithful parishioners who have worshipped in and cared for the ancient foundation.
