A Prothonotary Warbler (Protonotaria citrea) captured 19 August 1976 in a mist net at Blue Sky, 1920 m elevation on the east slope of Hart Mountain, on Hart Mountain National Antelope Refuge in Lake County is apparently the first record for Oregon. I took it from the net within 1 m of a small stream in riparian habitat dominated by Ponderosa Pine (Pinus ponderosa), Quaking Aspen (Populus tremuloides), and Mountain Alder (Alnus tenuifolia). This hatching-year (ca. 15% skull ossification) male in excellent plumage (no molt in progress), wing chord of 70 mm, and weight of 13.0 g (light fat) was banded, photographed (Figure 1), and released. Two color photographs showing the bright orange-yellow head and neck, the bluish-gray wing and tail feathers, white under tail coverts, and white inner webs of the tail feathers are on file with the Oregon Bird Records Committee and the Hart Mountain National Antelope Refuge.
