Periodically, we list the species for which we need good quality blacka n d - w h i t e photographs to illustrate forthcoming papers. O n this occasion, we have listed the urgent requirements separately. Photographers who are able to help should submit prints (or original colour transparencies for conversion) to Dr J . T. R. Sharrock at the editorial address. Please note, as previously announced (Brit. Birds 73: 541), that, unless a specific request is made (on the back of each photograph) for their return, prints will be retained for reference and possible further use.
