Bob Sallinger, a longtime environmental activist involved in numerous conservation efforts across Oregon, died Thursday. He was 57 years old. For decades, Sallinger was the face of various conservation efforts throughout Portland and the rest of the state. He frequently appeared in local news stories about those efforts, whether it was peregrine falcons on the Fremont Bridge or raising concerns about a new baseball stadium. A graduate of Reed College, Sallinger worked for three decades with the Bird Alliance of Oregon, formerly known as the Portland Audubon Society, most notably as its conservation director. …That includes fighting to protect peregrine falcons nesting on the Fremont Bridge and other bridges across Portland. Today, the Fremont Bridge has one of the most productive falcon nests in Oregon. …Many of his efforts sprang from his passion for wild birds, especially protecting marbled murrelets and the northern spotted owl, the latter of which is a threatened species.
