OILED BIRDS. The menace to birds of oil in the sea continues. The assistance of bird watchers and others is urgently requested by the Royal Society for the Protection of Birds who wish to determine whether there has yet been any significant change in oil-pollution in British waters. The number and species of oiled birds found during 1957 should be com- municated to The Secretary, R.S.P.B., 25, Eccleston Square, London, S.W.I. Negative results are of as much value as positive ones. A form on which results can conveniently be entered during the year is available from the R.S.P.B. Several oiled guillemots and razorbills were to be seen at Aberystwyth during the past autumn and winter.
