Waterfowl Counts
Loess Bluffs National Wildlife Refuge was established in 1935 as a refuge and breeding ground for migratory birds and other wildlife. Our 3,500 acres of wetland habitat often finds itself so full of migrating waterfowl you can hardly see the water. Waterfowl counts are taken once a week during the peak of migration and posted here for all of our refuge birders.
When there are such large numbers of one species, the bird
numbers are determined based on a calculation. We look at the number of birds
in smaller grids and calculations are used to determine the total number of
birds in that area in every unit. For other species, they are counted individually (i.e. trumpeter swans, eagles, shore birds).
