Starlings are amazing
Back in May, Amy Schwartz posted a photo of a starling that shethat had ringed that morning:
Impressed by the subtlety of the coloration, I wondered what would happen if I increased the colour saturation. I did this very simply: in the free image editor GIMP, I selected the parts of the photo that were starling (omitting the human hand and the background), and using the Hue-Saturation tool I wound the saturation up to 100%. Then I did the same thing again. Here is the result, with no other editing at all:
What an extraordinary riot of colour, in a bird that we mostly think of as “basically black with dots.”
So I thought I’d try the same trick on another starling photo, this one from the All About Birds page on the European Starling. Here is the original:
And here is the result of saturating the colours — this time through three cycles.
So my question is this: can other starlings see all this colour? In their own closed starling-centric world, are they fabulously colourful? Is this something close to what is perceptually apparent to animals whose eyes are attuned to different wavelengths from ours?that
