Research Wildlife Biologist

Primary Responsibilities: 
Conducts applied research in support of USDI land and wildlife managers. Responsibilities include establishing partnerships with federal, state, and academic collaborators, developing research strategies, writing study plans, developing special field/lab investigative techniques, complementing field studies with controlled laboratory or pen studies, solving often difficult field logistical problems, overseeing field research studies, conducting data analyses, presenting results at workshops and symposia, and by authoring formal publications. Mike has spent most of his early careeer conducting field studies of waterbirds, wetlands, and Chesapeake Bay. His work focused for many years on wintering waterfowl ecology, especially on Chesapeake Bay canvasbacks. Current research topics include investigating the role of exotic nutria on marsh loss at Blackwater National Wildlife Refuge, establishing the importance of horseshoe crab eggs to spring migrant shorebirds in Delaware Bay, and investigatinig the population status of Chesapeake Bay diamondback terrapins.


M.S., Wildlife Science, Cornell University 1975

Dissertation: Wood Duck Ecology and Management within the Green-Timber Impoundments at Montezuma National Wildlife Refuge 

B.S. Electrical Engineering , Clarkson College of Technology, 1966

Areas of Expertise/Interest:  Field studies of waterfowl and wetland birds, e.g., stopover ecology of migrant shore and wetland birds, ecology of wintering waterfowl on Chesapeake Bay; application of stable isotope methods to food habits and trophic investigations; use of conventional VHF and satellite telemetry with birds; wetland dynamics and restoration; island ecology and management for wetland birds.
