Refuge-wide estimates of waterfowl (geese, ducks, swans, etc.) are conducted from September through April. These surveys are not on a set schedule but are held on average once every two weeks. Counts of Sandhill Cranes, White Pelicans, and Bald Eagles are usually included on these surveys.
A county-by-county survey conducted the second Saturday each May, the NAMC is a volunteer-run count. Typically, the count covers Quivira, but additional areas in the county (such as area towns) are frequently checked. Check back here in 2013 for the latest results.
An all-day count held annually in mid-December, this is a group effort to find as many birds as possible within a 15-mile diameter circle, centered in the middle of Quivira. As many as a hundred species (and several million birds) have been recorded in past years. Quivira's first CBC was held in 1959, and the count has been conducted annually since except for 1966 and 1982.
Note: CW = seen during the count week, but not on count day; bold type denotes a species new to the count.
