Wildlife biologist intern Ale Larranaga holds a red-eared slider turtle egg she removed from a nest July 26, 2022. The red-eared tail slider eggs are distinctive by their soft shell, which dimples easily under pressure. Wildlife biologists with the Portland District, Army Corps of Engineers regularly look for and remove red-eared slider turtles and their eggs from Willamette Valley Corps locations because the species is invasive and competes with native turtles for food and habitat, especially nesting sites.
