Chesapeake Audubon Field Trip Leaders

Marian Dodson Argentino, Field Trip & Program Director for CAS, is an ardent nature enthusiast who greatly enjoys being outdoors
 discovering whatever the day has to offer.  Although her primary interest is birding, she misses few opportunities to learn about all of the
 flora and fauna that crosses her path.  She invites you to come along.  Who knows where you might go or what you might see next?

Hugh Simmons is President of Chesapeake Audubon, and is known for his friendly and helpful attitude. Hugh knows his birds, and where to find them.

Bryan MacKay is the author of Hiking, Cycling and Canoeing in Maryland: A Family Guide (2008) and Baltimore Trails: A Guide for Hikers and Mountain Bikers (2002). He especially enjoys introducing people to unique natural places.

Timothy Houghton  moved to Maryland last summer and is now teaching literature and writing at Loyola University.  He has led walks in many in his previous states of residence, most recently Kentucky, where his last hike was to find the Swainson’s Warbler.  Tim’s favorite season of birding is during spring songbird migration and he especially loves warblers.

Mark Schilling, a former staff member, lives on the Eastern Shore and participates annually in the NJ Audubon World Series of Birding. He specializes in birding by ear, and particularly enjoys having novices on his trips.
