Great stuff Larry.
Sorry to hear that P&K let you down with the pelagics (I've not used it for them yet....); as far as the Noddies go, when I visited Michaelmas Cay (offshore from Cairns) I saw thousands of Common Noddies and only a handful of Black Noddies amongst them. Whether this is a reflection of their relative abundance in the area I really couldn't say...
If you take a trip out there July/August you will almost certainly see Common as they nest throughout the year, but maybe not Black as they don't start nesting again until the Spring. Certainly worth the trip for the snorkelling!
According to Harrison's 'Seabirds', Black Noddy has a whiter and more extensive cap than Common (Brown) Noddy; sharply demarcated lores and longer bill. The underwing is different in having a uniform colour without darker margins; Common has the darker margins to underwing which is otherwise paler. Common appears 'two-toned' at sea whereas Black overall looks a more uniform colour. Black is also a smaller bird.
Hope that helps a bit!
