** Correction to this posting see below*** (Rallus obsoletus)

I have been in contact with eBird, and the consensus is that this small population of birds is in fact a Ridgway's Rail, have been split off from the Clapper with the 55th AOU supplement. I actually saw my first RIDGWAY'S Rail a couple of weeks ago in this same location, but only got a marginally decent image. I tend to get a bit obsessive about getting a publishable image, something I can use in one of my stories...so, after several hours waiting, a lovely young couple wandered out into the open for me. This female was not only in the open, but less than 15 feet away, and..in the sunshine!!

Great photo of a great bird. I just believe it is a Ridgway's Rail (http://www.birdforum.net/opus/Ridgway%27s_Rail) which was split from Clapper Rail. The narrow post-split Clapper Rail should not occur in Baja California.

You are correct NJ Larsen, I have been in contact with eBird and that is the consensus considering the split. Interestingly enough, of my dozens of guides and reference books, I can find no listing of the Ridgway's in anything.

Nice one Thomas! It's great when species get split off giving you a new tick, isn't it.

Think you'll generally find that Opus is pretty up-to-date. The trouble, now, with books and the like, they're virtually out of date as soon as they're printed; taxonomic changes happen so quickly.
