The great blue made a lot of noise taking off from the pond. Must have been annoyed by all of the ducks. Unfortunately, I still haven't been able to get close enough to get a good identification shot on any of the ducks (my small camera doesn't have much of a zoom). There are at least three species, though, one of which is posted in 'birds'. It may be a female canvasback, but the sunset lighting makes it difficult to tell.
