Here is the schedule for the New Haven Bird Club's April activities.
Larry Bausher, Publicity Director
Thursday, April 8—Christopher Clark, Ph.D.
How and why birds 'sing' with their feathers. The Jones Auditorium
of the Connecticut Agricultural Experiment Station, 123 Huntington
St., New Haven, CT.
Like humans, birds produce sounds to communicate both through
vocalizations and also mechanical sounds; the latter being similar to
human instrumental music. Whereas bird vocalizations have been
scientifically studied for decades, the mechanics and function of
mechanical sounds has received relatively little scientific
attention. This talk will present the results of recent research on
the tonal sounds (so-called 'whistling' sounds) that birds such as
snipe, doves, and hummingbirds produce during flight. Birds can
produce a a diverse array of sounds with their feathers, which will
be demonstrated with high-speed video and sound recordings of the
courtship displays of several species of Hummingbirds. Moreover, the
physics of how these sounds are produced yields insight into why
birds produce them.
Social half-hour at 7:00, program begins at 7:30. For more
