Birders Capture Image of ‘Odd’ Duck and Accidentally Make a Key Scientific Discovery
Chicago birders photographed a rare white‑winged scoter eating an invasive red swamp crayfish, confirming a link in the local food chain. Loyola University Chicago researchers studying these crayfish found they contain microplastic levels higher than previously recorded, raising concerns about how these pollutants move through aquatic ecosystems.
Nearly 7,000 watercraft inspections conducted in Douglas County, MN
Douglas County completed nearly 7,000 watercraft inspections in 2025, with only one lake testing positive for zebra mussels and no new invasive plants detected. Signal crayfish were also monitored by the Minnesota Department of Natural Resources. 203 traps were checked and no signal crayfish were detected.
