These Big, Fierce Birds Found Love in Australia—and Laid the First Southern Cassowary Eggs at the Adelaide Zoo in 34 Years

A female southern cassowary at Adelaide Zoo in South Australia laid two bright green eggs after being paired with a potential mate, the first eggs laid at the zoo in 34 years and a breakthrough for a captive breeding program managing genetic diversity for the endangered species.

Whether the eggs are viable and will hatch into chicks remains unknown; zoo staff are monitoring them closely.
