Despite the resolution of the identification debate, it is important that seawatchers and pelagic birders remain familiar with key criteria needed to distinguish Fea's Petrel from Zino's and Soft-plumaged Petrels. Here is a series of pictures of a Fea's Petrel that I took in deep Gulf Stream water off Cape Hatteras, North Carolina during one of Brian Patteson's trips. Brian's black and white photos of the same bird (see Figs. 8-9) appear in the second installment of Mike Tove's comprehensive review published in ABA's Birding magazine.
Figure 1. Fea's Petrel Pterodroma feae, Gulf Stream, North Carolina USA 7/20/96 (photo Copyright © 1998 Angus Wilson) Strong brown 'M' pattern typical of many Pterodroma. Striking pale uppertail coverts contrasting with gray mantle. Soft-plumaged Petrel in contrast, has a darker 'rump', that matches the mantle. This photo also shows the slightly darker tail feathers projecting from under tailcoverts. The tail looks long. The secondaries and inner primaries appear paler than the outer primaries.
Figure 2. Fea's Petrel Pterodroma feae, Gulf Stream, North Carolina USA 7/20/96 (photo Copyright © 1998 Angus Wilson). Long slender wings. Photographs of suspected Zino's Petrels off Bugio, show broader wings, more obviously rounded wing tips and a much reduced 'M" mark. Again this photo of a NC bird shows the pale secondaries and striking off-white rump covering darker tail feathers.
Figure 3. Fea's Petrel Pterodroma feae, Gulf Stream, North Carolina USA 7/20/96 (photo Copyright © 1998 Angus Wilson). Note the dark 'cap' extending across crown and covering eye. Bill relatively robust. Breast band very incomplete.
Figure 4. Fea's Petrel Pterodroma feae, Gulf Stream, North Carolina USA 7/20/96 (photo Copyright © 1998 Angus Wilson). Very distant view I'm afraid, but shows the characteristic dark underwing contrasting with immaculate white belly and vent. The incomplete breast-band barely extending onto the breast is obvious.
