Continuing immature male, which today started singing - not the familiar high-pitched whistle, but a scratchy song a bit like an Anna's. I'd never heard/noticed Costa's doing this before, and could only find one recording on Xeno Canto, and none on the apps. This is from Birds of the World: "In California, immature male gives song approaching complexity of male Anna's Hummingbird, but “fainter and less sustained” (Woods 1927, F. G. Stiles in Wells et al. 1978: 546)."
