Figure 3. Common Woodpigeon Columba palumbus specimens (NHMUK 1930.8.14.1, NHMUK 2000.11.1, NHMUK 1923.3.8.1); the phaeomelanised plumage is probably the product of a similar mutation as 'recessive red' in Feral Pigeon C. livia (cf. Fig. 2D) (Harry Taylor, © Natural History Museum, London) Figure 4. 'Perdix montana', the phaeomelanistic variety of Grey Partridge P. perdix, NHMUK 1939.12.9.3717, Nasavad, Slovakia, 10 November 1932 (at left) and NHMUK 1939.12.9.3716, Norfolk, England, October 1911; the gene for this recessive mutation is present throughout the range of the species and is therefore a frequently recurring variety on the borderline of being recognised as a morph (Harry Taylor, © Natural History Museum, London)
