Streaked Horned Lark Patrol

Sauvie Island | March – July

Portland Audubon is working with the Oregon Department of Fish and Wildlife (ODFW) to monitor for Streaked Horned Larks and other bird species at agricultural and grassland pasture sites at ODFW’s Sauvie Island Wildlife Area.  

In recent years ODFW and partners have worked to restore grassland habitats on Sauvie Island to help attract once common breeding grassland bird species (e.g. Western Meadowlark) back to the island. These surveys help track bird response to these restoration efforts as well as keep alert for a glimpse of the rare Streaked Horned Lark. This is the only bird species (subspecies of the Horned Lark) on the Endangered Species List that breeds in the Portland Metro region. Less than 2,000 birds remain. This project adds to Portland Audubon’s overall efforts to help bring this bird back from the brink.
