Uploaded this picture to Birdforum a few years ago but what the heck, this is my blog. On the left is an adult Japanese Peregrine Falcon (Hayabusa - Japanese) Falco peregrinus nominate/japonicus? (Photographed at Toyano, Niigata, in October 2007) and right, an adult Australian Peregrine Falcon, Falco peregrinus macropus (female, the smaller male was following her, at the Toowoomba cemetery, May 2002 -slide film and scanned in 2002).
The Japanese falcon is generally a paler species with an 'open-cheeked' black helmet compared to the Australian species which is darker and has a much fuller helmet.
What ever the case it's nice to see both species, and love the blue skies in these pics.

Nice comparison!
The resident race of Peregrine Falcon in Thailand also has entirely black cheek too.
The shot on the left is a nice one, I've never really managed a decent shot of a Peregrine.........
I saw many of them in the UK, weird to think it's found in England, Thailand, Australia and Japan. Not to mention Africa and the Americas too...........
Saw one today just like the one on the left. At least that is from a fair distance but our UK race would certainly appear to look more like the japanese than the aussie.
Hello. Just posting to let anyone know who cares that I saw what I'm pretty sure was a Peregrine in Bangkok two days ago. I was at the top of a building adjacent to the Sutthisan station, and had a very clear view of it. It was near dusk, and I had good binoculars with me; I got a very good look at it, but since I'm from the states I was very shocked to see such a bird in this area. Anyhow, it landed on a large tower several miles directly to the west, so perhaps it stays there in the evening. Robert, phone -- 08 248 71512
