     The Audubon Naturalist Society's April lecture features
Robert Leberman and Robert Mulvihill, speaking on "Thirty-five
Years of Learning from Birds", at Baird Auditorium, Museum of
Natural History, Smithsonian Institution, 10th and Constitution,
NW, Wash. D.C.  The lecture begins at 6 p.m.  For tickets, call
202-357-3030.

     The talk is about a pilot birdbanding study, using mist
nets, that Robert Leberman began in 1961 at the Carnegie Museum's
newly established Powdermill Nature Reserve, located in the
Appalachian Mountains east of Pittsburgh.  Joining Leberman in
1983 was Robert Mulvihill.  From their data, Leberman and
Mulvihill have discovered trends in hummingbird migration and
Ovenbird survival, a dietary basis for plumage colors in Cedar
Waxwings, and molt characteristics in several other passerines.
