Dozens of evening and pine grosbeak carcasses have been found on State Route 20 near Colonial Creek Campgrounds in North Cascades National Park, according to a July 17 report. The birds, a federally protected species with a 92% population decline over 50 years, are usually seen alive in the park but were struck by vehicles in recent weeks.

North Cascades Institute communication manager Christian Martin called the incident a 'grosbeak massacre.' Resident Nikita Kozhekin reported seeing dead birds every 100 feet along the road in late June. The park is a known hotspot for these threatened birds, but the roadside deaths are an unusual summer occurrence that officials are investigating.

The National Park Service and wildlife agencies are working to determine the cause of the increased bird fatalities. No specific next steps were mentioned in the source, but the incident highlights ongoing conservation challenges for a species listed on the brink of endangerment.
