The angle from which the photograph was taken could be somewhat misleading in 
regard to the tail length and wing length.  See the various photographs of a 
Great-winged Petrel from La Jolla, CA.  One gives a similar profile to the bird 
you photographed, while most appear to show a longer winged bird and one with a 
longer tail.
