Rarity of Influenza A Virus in Spring Shorebirds, Southern Alaska
Highlights
To the Editor: Knowledge of avian influenza (AI) virus and its host epidemiology and ecology is essential for effective monitoring and mitigation [1]
Research in the Delaware Bay area, eastern United States, suggests an ecologic and epidemiologic viewpoint of AI virus in wild birds in which shorebirds are predominant hosts in spring; research in Alberta, Canada, suggests that waterfowl are such in autumn [2,3]

Summary
To the Editor: Knowledge of avian influenza (AI) virus and its host epidemiology and ecology is essential for effective monitoring and mitigation [1]. Research in the Delaware Bay area, eastern United States, suggests an ecologic and epidemiologic viewpoint of AI virus in wild birds in which shorebirds (family Scolopacidae) are predominant hosts in spring; research in Alberta, Canada, suggests that waterfowl are such in autumn [2,3]. To increase knowledge of AI transport among shorebirds in spring in the North Pacific, we conducted AI virus surveillance during the springs of 2006 and 2007 at the Copper River Delta area of Alaska. In 2006 and 2007, 1,050 shorebirds (Western Sandpiper, Calidris mauri, and Least Sandpiper, C. minutilla) and 770 Glaucous-winged Gulls (Larus glaucescens) were sampled during peak spring migration at Hartney Bay, Cordova, Alaska (60°28′N 146°8′W; Table). Species and sample sizes of wild bird hosts screened for avian influenza virus, Cordova, Alaska, May 2006 and May 2007
