On 13 September 2019, I observed an adult Red-necked Grebe (Podiceps grisegena) accompanying two large young in juvenal plumage (Figure 1) near the boat-launch site on Big Lake, ~6 km north of McArthur, Shasta County, California. Covering ~3 km2, Big Lake is a relatively shallow (~4 m deep) spring-fed lake at an elevation of 1008 m. With other connected water bodies (Horr Pond, Tule, Little Tule, and Fall rivers), it is part of a large hydroelectric project constructed in the early decades of the 20th century. Th lake and several small islands are surrounded by a dense band of emergent aquatic vegetation, primarily tule (Schoenoplectus acutus). Pied-billed (Podilymbus podiceps), Eared (Podiceps nigricollis), Western (Aechmophorus occidentalis), and a few Clark’s (A. clarkii) Grebes nest on the lake.
