| Notes | “My goal in this research was to identify environmental features or habitat characteristics that predict shorebird abundance in Oregon estuaries“ (p.72). The author found differences in preferred habitat between spring and fall migrations. In the spring, shorebirds have a relatively narrow window in which to make it to their Arctic breeding grounds. In this intensely social time, the birds preferred larger estuaries. On the other hand, in the fall, shorebird preference was more strongly influenced by habitats. Marsh habitats and grasslands for roosting sites were good fall density predictors. Estuarine channels were preferred feeding sites. In Oregon, the Coquille River estuary, Coos Bay and Siletz Bay were the preferred fall sites. This most interesting and enlightening work can help wildlife managers better understand the relative importance of various habitats. |
