I learned that Great Blue Herons are incredibly adaptable, and live near lakes and wetlands across all of north and central America, and their nesting area is called a heronry. The only predator that consistently hunts them as full grown adults is the Bald Eagle, because grown herons fight back with their sharp bills.
I learned a lot about Prairie Dog family structures and breeding. I learned they mate underground, and they have nurseries in the deeper more remote parts of their burrows where they raise the young until they're about 5 months old, which is why you never see baby prairie dogs, just juveniles and adults. I also learned that they're particularly susceptible to Bubonic Plague, and it can wipe out whole colonies, but there are vaccines that have been air dropped on at-risk colonies to inoculate them against the disease.
