318 THE ESSEX NATURALIST some 5 years earlier that he wrote the following in a letter to Heysham: — "I am happy in being able to send one rarity, viz.: two eggs of the Hawfinch, which till this spring I never saw. The nest is built in the most careless manner, and consists of a few coarse sticks, then a layer of that coarse lichen which grows on the stems of oaks, and (is) lined with a few roots. It is also extremely shallow. They seem to build in any situation. The nest I took was in a whitethorn, about 4 feet high, and I saw one on the top of a tall spruce fir ... . I have now a full-grown young Hawfinch in confinement, which was caught in our forest about a fortnight ago". Until Doubleday recorded finding the bird all the year round at Epping it was thought to be purely migratory. The great variety of country met with in our county has resulted in the number of species of birds occurring in it to be well above the average for the whole country; the ponds in the Epping Forest area provided from time to time a variety of uncommon birds: for example, he was given a Wood Sandpiper in May 1840, in full summer plumage, which had been shot at a pond near Epping by "a fellow celebrated for poaching". His observations on many other Essex birds were contained in numerous private letters to fellow naturalists, and in correspond- ence to scientific magazines, particularly The Zoologist. We must not pass from the subject of birds without men- tioning that he was responsible for first noting the Little Ringed Plover in this country. This was in the year 1845 and it was at Shoreham that the bird was obtained. The Blue-headed Wagtail was first taken by Doubleday in this country, at Walton-on-the- Naze, on October 3rd, 1834. A description of the bird was given to Heysham, and the event was briefly recorded by Doubleday in Loudon's Magazine of Natural History. Shortly after it was shot he wrote: "When I came to London I took it to Bruton Street (where the Museum of the Zoological Society then was) and there I met with Bennett, Gould and Yarrell, all of whom at once pronounced it Neglecta". This bird was kept in his own collection until all his birds were sold in 1871. In 1836 Doubleday attempted to revise the classification of British birds by publishing A Nomenclature of British Birds. He was unhappy about the existing catalogues, and it was an effort systematically to classify all the species found in Great Britain and Ireland. Although it ran through four editions in ten years, it was not received very enthusiastically, and came in for a good deal of criticism. It was undoubtedly his accounts of seasonal plumage changes, nesting habits and bird behaviour, that put him in the forefront of ornithologists in his early years.
