Transcript:
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.
packratjohn: The vent is the opening, analogous to to the anus. The cloaca is a chamber, analogous to the rectum and bladder combined. In spite of notsooldguy’s masterful explanation of the nature of guano, I had a feeling I would get in a lecture as well. :-)
sphinx wormwood: Actually it is either. Bat guano was primarily used in the extraction of potassium nitrate for black powder in guns in North America. Sea bird guano (mainly from Chile) was used for explosives in Europe until the late 1880s when it was discovered how to make it from coal. It was mined for fertilizer until WW-I, transported by sailing ships into the 1920s. The City of Alberni, the last commercial sail cargo ship, was sold in 1944 along with its lumber cargo, after losing a battle with Cape Horn.

Someone’s beak is so far up the boss’s cloaca they can taste seed.
