U.S. Fish & Wildlife Service Birds Bill Williams River National Wildlife Refuge Birding at Bill Williams River National Wildlife Refuge Created in 1941 as part of Havasu National Wildlife Refuge, the Bill Williams River National Wildlife Refuge encompasses approximately 6,000 acres along the Bill Williams and Lower Colorado Rivers. The four major areas of the refuge include the open waters of an arm of Lake Havasu, the Delta Marsh, riparian woodlands along the Bill Williams River, and surrounding upland deserts with dramatic cliffs. The refuge contains the largest remaining nativevegetation dominated riparian forest along the Lower Colorado River and the only one that is still flood re-generated. Due to the location of the refuge and its rich habitat diversity, it is an important breeding, wintering, and migratory stopover point for birds, as well as providing habitat for many other wildlife species. The 353 bird species are listed in accordance with the 7th edition A.O.U. checklist and the 2012 supplement. If you should find an unlisted or rare species during your visit, please contact the Refuge staff and provide a description on the form on the last page. Seasonal status and abundance categories are to be considered as guides and should not be viewed as hard seasonal dates because birds and migration are dynamic and do not follow the calendar definitions of spring and fall. Summer status indicated for many nonbreeding species of shorebirds, terns, flycatchers, vireos, swallows, warblers, tanagers, and grosbeaks actually refers to early fall migration, which begins in July and August for these groups. As landscapes change due to human activities and natural processes, species populations and distributions must change as well. Over time, species may become locally absent (extirpated), restored, newly arrived, endangered, or even extinct. Some have always been rare on the Lower Colorado River. On the Bill Williams River NWR, species once common but now absent or rare include Vermilion flycatcher. wood storks, wood ducks, and vermillion flycatchers. Species that have recently arrived include Eurasian collared doves, indigo buntings, and northern cardinals. Many riparian obligate species that have declined in most areas of the southwest due to habitat changes remain common on the Bill Williams River where their habitat has been restored. We manage habitat to help recover endangered species as well as declining species including many riparian forest birds such as the yellow-billed cuckoo and summer tanager.
