Species notes
Rather large, wholly dark petrel. Often found with much commoner, but very similar White-chinned Petrel and is not easily identified unless distinct black bill tip of Westland can be seen (White-chinned has pale bill tip). Slightly smaller Parkinson’s Petrel looks very similar to Westland, but favors warmer tropical and subtropical waters and has a smaller, more rounded head and slightly slimmer bill.
