My issue is the disparity of the pictures, with the bowtie picture having the duck's entire neck almost completely in shadow, while the shadow is comparatively minimized on the necktie image. It'd be nice to see both options under both light and dark conditions.
That said, I currently prefer the necktie; it provides an element to the rest of the body. I'm the bowtie picture, everything is happening around the head - beak, eyes, hat, bowtie - leaving the rest of the body comparatively empty.
Oh, I found it interesting - there were a number of things I'd just never really considered about having (or trying to control) large bird populations in cities. I find it very informative!
I'm sorry about your snow, though :)
