Sticking with the pool themed posts here's another.
When it comes to song birds, we all know about the "fecal sack" or "poop pouch" right?! This is a feeding parents reward for bring the young food. The adult will fly off with this tough mucous membrane encasement of poop to be discarded away from the nest. It's their way of nest cleaning and keeping the nest free of waste and odor that might attract unwanted predators.
I've also seen Robin's carrying off blue egg shells too. Apparently, performing the same nest keeping duties, which all makes sense. However, I found the following in the pool the other day; a fertilized Robin egg! It would seem that an adult Robin was carrying this egg off, which it deemed unhatchable maybe, to deposit away from it's nest but it landed on the pool instead, YUCK!

One of the odder things I've found in our pool over the years.
