1. Bald Eagles: A Conservation Comeback Marker
Bald eagles are at the top of the food chain, making them vulnerable to environmental toxins like DDTa chemical once used to control insects. DDT entered waterways and was consumed by fish, a major food source for eagles. This caused eagles to become sterile or lay brittle eggs, leading to a dramatic decline in the eagle population, which reached an all-time low by 1964.
Through breeding and hatching efforts, the Columbus Zoo successfully released 20 eagles into their native habitats between 1979 and 2005. Zoo staff used two methods: fostering (transferring eagles born in human care to a nest in their new habitat) and hacking (placing older eaglets on artificial nesting towers near suitable habitats until they learned to fly). These efforts were crucial to ensuring the survival of the newly released eaglets.
