Overview

• Oregon Zoo says the 8-year-old polar bear will depart next month, with Portland visitors able to see her through the first week of September.
• Brookfield Zoo will place Amelia Gray with resident bears Hope and Hudson in the Great Bear Wilderness habitat.
• The zoo expects she could be on public view in Chicago as early as October after health and acclimation checks.
• The transfer follows AZA-managed plans to sustain a genetically diverse population, with a potential future pairing with a male to support cubs.
• Nora will be solitary again in Portland, which biologists note aligns with typical polar bear behavior.
