Most of his early research was on bird migration and orientation. He was a cofounder (with L.R. Mewaldt) of the Point Reyes Bird Observatory, served as its Director for a period, and continues his involvement with migration research and bird observatories in general, more recently helping start the Klamath Bird Observatory working in southern Oregon and northern California.
After a stint as a professor teaching at Dickinson College in Pennsylvania, he moved to Hawaii in 1976 where he began work on endangered forest birds for the Forest Service as a Research Ecologist. His work there focused on the behavioral ecology of the birds, especially foraging, population dynamics, and demography. In 1981 he and his family moved to Arcata, California to join the Forest Service's Redwood Sciences Laboratory.
Current Emphases, Studies, Projects
One of his principal research topics here has been on an old-growth dependant bird, the Marbled Murrelet, involving extensive research from Alaska to California, both in inland forests and much work on monitoring offshore populations of this seabird.
His other principal work is on landbird monitoring, especially involving census and constant effort mist netting.
An import result has been the Klamath Landbird Monitoring Network of stations in northern California and southern Oregon, with the Klamath and Humboldt Bay Bird Observatories, and heavy involvement with Partners in Flight, especially being co-chair of the Monitoring Working Group, and with the North American Banding Council where he serves as chair.
Since 1994 he has directed research at a bird monitoring station in Costa Rica, now one of the longest running stations in Latin America. Beginning in 1980 he has conducted research on an island off New Zealand involving monitoring and reintroduction of native birds.
He has published more than 150 scientific articles and edited several books on bird monitoring and the Marbled Murrelet. A list of his publications can be found at http://www.fs.fed.us/psw/topics/wildlife/birdmon/BirdLabPubs.shtml
