  1. Funny! when I was a kid, I always saw this bird (all around the NY metro area) with beautiful, irridescent feathers (never noticed the blue tinge on the beak); we called them starlings. Haven't seen them in recent years; then again I've stayed away from the NY metro area for the past 30/40 years.

    1. Yes, that is a European Starling. It's non-native to North America and out competes many of our native birds for food and habitat. There's a year-round open season on shooting them here in Michigan.

  2. The bird graphic suggests that the bird would be a tetrachromat. Some molluscans (bivalvia in particular) may have 16 visual opsins making them 16-chromats. In humans the opsin gene is carried by the X-chromosome and in at least one documented case a mutation of one opsin gene shifted its color sensitivity peak; the other on the other X-chromosome was normal: both genes were expressed in the retinas, making the person a tetrachromat, who could see differences in shades of color imperceptible to others. And the perception of light polarization is common in mollusc, arthropoda and chordata.

  3. How come both images don't look the same to me? Am I a bird, or is it my bird brain?

  4. Mozart had one for a pet. Apparently they can sing, too.
