Chris, sorry on rereading, I realised that the bird below is into its third year, when I have called it a second year bird. August puts it into its third year. I should perhaps have said second summer. This certainly tests the brain's ability to hold information. It's not hard to understand, it's getting the whole picture straight which is the challenge.

Sorry, it's getting complicated, and I am not explaining myself well. I was looking at the apparent difference between the Ps of an adult and a 2nd year bird in August in the book, and taking it back mentally to how I would expect the Ps of those same birds to look in April. And then trying to layer that on what I know about longipennis.
