The Trevor Zoo Herons are BACK. Help us keep this broadcast streaming by giving to the Trevor Zoo. https://www.millbrook.org/zoodonations. Say hello to Heather and Hudson, two wild Great Blue Herons, living 90 feet above the Trevor Zoo! http://www.millbrook.org/trevorzooherons. Watch them nesting above our wallaby and emu enclosure. Wilds herons have been nesting in the trees above the zoo for the past 8 years. The Trevor Zoo, a member of the AZA since 1989, is the only zoo in the world located at a high school. About 75 members of the student body care for the animals on a daily basis, feeding and cleaning about 180 animals from 80 species, nine of which are endangered. It’s a one of a kind living-laboratory that rewards the students involved with incredible learning and responsibility experiences.
