. Brimleyana. Zoology; Ecology; Natural history. 118 J. Christopher Haney et al. k*. Fig. 1. Specimen of nominate Pterodroma mollis, showing underparts, collected from Antipodes Island, 13 February 1969, by J. Warham (Department of Zoology, University of Canterbury, Christchurch 1, New Zealand). Madeiras (James and Robertson 1985). Measurements of wing and body length in Fea's petrel overlap extensively with the black-capped petrel (Cramp and Simmons 1977, Harrison 1983). When we (J.C.H. and C.A.F.) compared specimens of P. feae and P. hasitata, we con- cluded that size differences between these two species would be difficult to detect under field conditions. The Freira petrel (a summer breeder) is significantly smaller than either the Fea's petrel or the soft-plumaged petrel (Cramp and Simmons 1977, Fisher 1989). Bourne (1983a) stated the P. madeira has less mottling on the flanks than P. feae. However, other accounts differ (see Cramp and Simmons 1977, Harrison 1983), and such relative field marks may not be useful at sea in the absence of direct comparison and experience. Status and distribution—We believe that the bird we observed must have been P. feae for the following reasons. First, the lack of a complete breast band eliminated southern soft-plumaged petrels. None of >290 specimens of the northern forms or numerous living examples examined by P. and F. Zino (personal communication) have a marked breast band, although a small minority of individuals with breast bands have been reported at sea off Madeira (taxonomic identity unknown; B. Zonfrillo personal communication). Generally, there is at least 1 cm of white between the two sides of the partial breast band in the northern species (F. Zino personal communication). Second, the large.
