Cross Creeks provides wintering habitat and protection for large numbers of waterfowl. In January duck populations will average 35,000 birds per day and during extremley cold weather these numbers may exceed 90,000 birds.

Waterfowl surveys have been conducted on Cross Creeks National Wildlife Refuge from the early 1960's. Both ground count and aerial survey methods have been utilized. Earlier surveys were conducted each week throughout the entire year with most counts occurring from the ground. In 1991, the refuge changed the waterfowl survey timing to bi-weekly counts from September 1 - April 15 and stated that the preferred survey method would be aerial surveys. In 1998 the surveys were further modified, changing the timing to bi-weekly counts from mid-October through the first week of March.

Normally, the surveys are conducted infrequently beginning in mid-October and ending in early March. Some of these surveys are now conducted using a fixed-wing aircraft with one observer in addition to the pilot, the rest are done by ground counts. This winter the refuge has made the difficult decision to suspend waterfowl surveys due to concerns about Covid-19.

Survey Data 

The waterfowl surveys conducted on Cross Creeks National Wildlife Refuge tell us a lot about how the refuge is being utilized. This data is essential for our managers to make the best possible decisions for the benefit of the wildlife. Over time, the data can show trends and fluctuations of the presence of migrating waterfowl. 
This graph shows over 40 years of waterfowl survey data! A peak count refers to the highest number of ducks recorded during a given year.
