Numbers of the Black Tern nesting in inland northern California, and of the Forster’s (Sterna forsteri) and Caspian (Hydroprogne caspia) terns as well, have decreased substantially during the drought-stricken early years of the 21st century, as detailed in this issue of Western Birds by W. David Shuford, Kristin A. Sesser, Khara M. Strum, David B. Haines, and Daniel A. Skalos.
Back cover: “Featured Photos” by Martin Reid of San Antonio, Texas: Long-tailed Jaegers (Stercorarius longicaudus) 5 km off Arica, Chile, 2 December 1993, showing variation in the plumage of nonbreeding adults and of a bird in its second winter (upper photo, top image). Note the barred central rectrix in the lower photo. In this issue of Western Birds, Peter Pyle and Martin Reid unravel the complex and hitherto inadequately understood cycles of molt in the jaegers.
