BIRDS Some Rough Notes on the Altered Status of Birds in North Fambridge, Essex From September 1935, when I came to live in North Fambridge, until September 1939, when I left on War Service, I kept notes of birds and mam- mals of interest seen, rarities, if any, dates of migrants' arrivals and de- partures, first and last song dates and so forth. I did not return home until the summer of 1945. During my absence, rough plot land covered with rosebushes, hawthorn and scrub had been ploughed up, as was pasture land. Certain marshes which used to contain reedy fleets were drained, so that the fleets are now merely muddy patches or are gone altogether. The drought of 1947 up till now, has also probably made a difference to the bird population. North Fambridge is a hamlet of about 250 people on the north bank of the Crouch estuary, nine miles up river from Burnham-on-Crouch, and thirty-seven miles (by rail) from London.
