Not a bird that comes to chum
slicks very often - this species often just cruises on by. Notoriously
difficult to separate from the closely related Zino's Petrel this
species can cause ID headaches. However, many of the birds we saw were
really quite different from Zino's with massive beaks.
The use of bill size as an ID feature reminded me very much of the
difference between Parrot Crossbill and Common Crossbill
