International Duck The nations, whatever their political troubles, are beginning

to co- operate with great efficiency over the study as well as the preservation of birds. A striking example is the formation of the British Branch of the Wildfowl Research Institute, which at the instance of the Trustees of the British Museum is to be centred at Tring. The whole tribe of duck are powerful migrants, and therefore can only be protected by common action along their lines of migration. The reconstruction of older decoys, as at Orielton in Pembrokeshire, and in the region controlled by the Severn Wildfowl Trust, will give, indeed are giving, more and more evidences of the range of wildfowl. One teal ringed at Orielton in December was recovered some eight months later in Finland. Another was -recovered in the same country five years after being ringed. The attempt to make some sort of a census of wildfowl has produced some very strange evidence concerning the variations in breeding. There seem to be barren and productive years, for which it is difficult to account. Those who wish to help or know about the work should apply to Miss Barclay Smith, British Museum, Cromwell Road, S.W.7.
