White bird with box: Guess who stopped and picked up a dozen glazed crickets on the way to work! Dark grey bird: Boy, that Jennings...what a white-noser.
Your science moment for the day…bird urine is white. In contrast to mammals who excrete nitrogen waste as urea, birds excrete urate which is white. The urine and the poo collect in a common chamber called the cloaca. Thus the urine and the poo are mixed together although it seems the urine tends to predominate. A cursory examination of the exterior or your car or truck will generally confirm this. Thank you for your attention. You may now return to enjoying the comics.
