Falcon tree.

On a sunny day in February last year I took this picture of a Merlin (Falco columbarius) at the Reifel Migratory Bird Sanctuary.

On a gloomier day in October 2008 (i.e., yesterday), I took a picture of a immature Peregrine Falcon (Falco peregrinus) that was perched on the same tree, same branch.

And through the magic of Photoshop, here they are perched side-by-side. The trees don't line up exactly because the two photos were taken from slightly different positions, but what fun nonetheless.

Here are the size stats for the two species, from The Sibley Field Guide to the Birds of Western North America: Merlin-L 10" WS 24" WT 6.5 oz (190 g); Peregrine-L 16" WS 41" WT 1.6 lb (720 g).

And now, photographic verification. Peregrine is bigger. A lot.

I found an active merlin nest once while doing rare plant surveys in Michigan -- I was pretty excited. The wildlife guys were so skeptical they made me escort them back, but there it was: bonified.
