In 2010, the Klamath Inventory and Monitoring Network (KLMN) of the National Park Service implemented the third year of their long-term landbird monitoring protocol (Stephens et al. 2010b). Klamath Bird Observatory, in partnership with the KLMN, developed the protocol and has implemented the monitoring since 2008. This annual report provides a summary of 2010 efforts, including (1) a summary of the monitoring protocol, (2) a summary of point count and area search surveys and constant effort monitoring efforts, and (3) a summary of birds detected at each of the park units where monitoring occurred.
