From late July through late August in 1991, the US Fish and Wildlife Service Migratory Bird Management Alaska Region conducted a fixed-wing aerial survey in western Alaska to estimate the abundance of Western Population Tundra Swans (Cygnus columbianus columbianus). The survey design consisted of a simple random sample of plots (quarter sections of 1:63,360 US Geological Survey topographic maps), each of which was surveyed by a 2-person aerial survey crew. The location and attributes of each observation were recorded onto paper 1:63,360 topographic maps and later transcribed into a computer and digitized. Observations were recorded as a single adult, adult pair, single with brood, pair with brood, or flock of adults,...

The Alaska Swan Survey Protocol was first developed by MBM-AK (James G. King, retired) in the 1960s to describe a standardized method of conducting aerial swan surveys in Alaska. Documentation of the protocol was last updated in 2007. All the swan survey data in the Alaska Swan Database were collected using this protocol.

From 1981 to 2009, MBM-AK collaborated with its partner, U.S. Forest Service Cordova Ranger District, to conduct spring nesting and late-summer trumpeter swan surveys on the Copper River Delta, Alaska. An annual summary report was produced by MBM-AK. As of the date that this metadata was written, only the 2004-2009 reports were available in digital format and archived in the FWS Alaska Regional Data Repository (AK_Swan_Database project). All the reports in paper format are available upon request from MBM-AK (see contact information elsewhere in this metadata).
