Upper Klamath Basin Field Station
The Humboldt Bay Bird Observatory was established in 1982 by Dr. C. John Ralph and Dr. Carol Pearson Ralph. The station is located adjacent to the Lanphere Dunes Unit of the Humboldt Bay National Wildlife Refuge west of Arcata, California. It is bordered to the east by the Mad River Slough and to the west by coastal dune forest. The dune forest supports a high diversity of tree and shrub species, including beach pine, Sitka spruce, Douglas-fir, grand fir, wax-myrtle, and Pacific madrone. The forest understory includes huckleberry, bear-berry, and a wide variety of lichens and mosses. Adjacent habitats include open pasture, and riparian and other wetland habitats. This diversity of habitats supports a high diversity of bird species. Common species include Allen's and Rufous Hummingbirds, Common Flicker, Western Flycatcher, Chestnut-backed Chickadee, Winter Wren, Wrentit, Swainson's and Hermit Thrushes, Wrentit, Yellow-rumped Warblers, Song Sparrow, Red Crossbill, and Purple Finch. Rare vagrants over the years include Black-billed Cuckoo, Yellow-billed Cuckoo, Ruby-throated Hummingbird, Least Flycatcher, Yellow-throated Vireo, Gray Catbird, Northern Parula, Chestnut-sided Warbler, and Blackpoll Warbler. Bird populations and demographics have been monitored at the station continuously since 1982, making the Humboldt Bay Bird Observatory one of the longest running stations in the nation. Educational tours and volunteer programs provide the opportunity to observe and learn about birds, and to train in bird monitoring and research techniques. At the station, students from other bird-monitoring stations, Humboldt State University, and elsewhere have been extensively trained in various techniques. The station is operated throughout the year, ranging from weekly in the winter to almost daily (at two sub-stations) during the fall migration, providing ample opportunities for people to experience and learn from the capture of birds. We are dedicated to the promotion of high standards in bird monitoring and research. For more information on HBBO, or to visit,
