Monitoring Neotropical and Migratory Birds in Alaska. Final Research Performance Report, 24 April 1997-23 April 1998

摘要

In 1997 monitoring of migratory land birds continued for the sixth year at the Creamers' Refuge migration station in a cooperative project with the Alaska Bird Observatory. Mist nets were used to capture birds on 42 days between 25 April and 14 June and 66 days between 15 July and 30 September. A new standard array of nets was established in 1997 using a subset of previous years' nets to reduce variations in net effort. Comparisons of capture rates in the original and reduced set with data from fall 1994-1996 found no significant differences.
