Birds of Modoc National Wildlife Refuge

Modoc National Wildlife Refuge, established in 1960, is located three miles southeast of Alturas, California in Modoc County. The area is one of a chain of refuges along the Pacific Flyway that extends from Canada to Mexico. The primary purpose of the refuge is waterfowl production and maintenance, and the lands which make up the refuge were purchased with funds collected through sales of Migratory Bird Hunting and Conservation Stamps.

Modoc NWR contains 6,283 acres surrounding the confluence of the north and south forks of the Pit River. Lying at an elevation of 4,365 feet, the refuge is situated on the western edge of the Great Basin Desert, with the Warner Mountain range on the east and the Adin Mountain range on the west. Several different habitat types are represented at Modoc including: freshwater lakes and ponds, farmland and irrigated meadows, sagebrush upland, and riparian corridors. This habitat diversity supports a wide range of wildlife.

Bird populations vary greatly in abundance and diversity according to the season. Large concentrations of waterfowl visit the refuge during spring and fall migrations, with a portion of these remaining through the breeding season. The best opportunity to observe the greatest diversity of bird life at Modoc NWR is during April and September. Visitors are encouraged to contact headquarters to get up-to-date information on current wildlife viewing opportunities.

A total of 232 bird species have been observed on the refuge, including 18 accidentals. At least 76 species have been documented as nesting at Modoc. Of all the birds listed, two are classified as endangered.

The following list includes birds which have been observed by refuge personnel and other individuals since the establishment of Modoc NWR. The list is not considered final, as observations will continue to add to its accuracy. All observations are appreciated and encouraged, and should be reported to refuge headquarters as soon as possible.

A few abbreviations have been used to assist the observer in determining status and seasonal abundance. Names are in accordance with the sixth (1983) American Ornithologist's Union Checklist of North American Birds.
