Résumé :	In recent years, the occurrence in Europe of Common Snipes Gallinago gallinago showing characters associated with the North American race G. g. delicata - notably on Scilly - has generated considerable interest and debate. Several features have been proposed to help separate deficata from nominate gallinago but little has been published to quantify these characters. All criteria previously suggested are reviewed here and, based upon field experience and examination of museum specimens and photographs of both forms, their effectiveness discussed. Consistent differences were found in the depth of the white tips to the secondaries, extent of white on the underwing-coverts, pattern of the axillaries, number of tail feathers, and the pattern and width of the outermost tail feather. If supporting evidence documenting these features is obtained, separation of gallinago and delicata should be possible in many instances.
