Bateman Island is n. of SR 240 on Columbia Center Blvd. to 1650 Columbia Park Tr. This 160-acre islet, at the mouth of the Yakima River where it flows into the Columbia, is an urban wildlife area. A 1-mile gravel trail loops through a wooded riparian habitat that is a haven for birds.
Birds reside here year-round, but their numbers peak during spring and fall migrations. From March to May look for dunlins, black-necked stilts, American avocets, greater and lesser yellowlegs, long-billed dowitchers and spotted sandpipers. Bird species increase again from August to November, and waterfowl are common in winter.
Historically the island was an ancestral Native American fishing and hunting ground. Near the trailhead, the Lewis and Clark Overlook has interpretive panels about the Corps of Discovery and the Tap Teel (Yakima) River. The island marks the farthest upstream point of the Columbia reached by the explorers in 1805.
