Biological Surveys

Large flock of Snow and Greater White-fronted Geese taking flight

Several types of surveys are undertaken throughout the year.  These help us to understand population sizes, trends, changes over time, or simply provide us a baseline of information.

Regular Surveys

The following are examples, and results, of surveys conducted at Quivira.

Waterfowl Surveys 

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.

Waterfowl population estimate/survey, most recent:  Wednesday, March 25, 2020 (survey, Refuge-wide).  Surveys are conducted September through March.  

NOTE:   the numbers below are either from formal, refuge-wide surveys or from informal estimates.  The data is incomplete and not to be disseminated for use as official.  Waterfowl estimates can also be obtained by calling the refuge phone number 620-486-2393 and ask for extension 105, or the same number after business hours (7:30 - 4:00 Monday through Friday) for a recorded message.

North American Migration Count (NAMC) 

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.  Click here for the most recent count results:  Bird List NAMC May 11, 2019


Christmas Bird Count (CBC)

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.

Breeding Bird Surveys

Most years, a Breeding Bird Survey (BBS) route is conducted twice during early summer (usually June).  This is done along a 25-mile route, with stops every half mile, where all birds seen and heard are recorded.
