Today I share an article from Lincoln Park Zoo on an incredible migration event that’s been happening since this past spring. Being an endangered species in Illinois the Zoo closed off part of the property to allow this amazing migration event. Read about the 560 Herons that homed here to nest during breeding season. That means that what I posted as being a Yellow-Crowned Night Heron a few days ago was more probably a Black-Crowned Night Heron. Amazing!!
