April 23rd: "Careless Whispers? Deciphering the Hidden Vocal Repertoire of a
Common Backyard Bird, the Dark-eyed Junco", Dr. Dustin Reichard, Assistant
Professor, Department of Zoology, Ohio Wesleyan University.



     Dr. Dustin Reichard is an assistant professor of zoology at Ohio
Wesleyan University where he teaches classes focused on Ornithology,
Organismal Biology and Animal Behavior.  He conducts research with his
undergraduate students investigating animal communication, sociality and
hormones in birds and other species, while also serving as co-curator for
OWU's Brant Museum of Zoology. Dr. Reichard earned his Ph.D. in Evolutionary
Biology from Indiana University, Bloomington, where he studied the structure
and function of whispered vocalizations in Dark-eyed Juncos.



     Ornithologists and bird enthusiasts alike have long been fascinated by
the diversity of songs and calls produced by birds throughout the year, but
often with renewed effort during the breeding season. These vocalizations
help us to identify species by ear, and the loud, melodic songs produced by
songbirds in the spring serve two important functions: attracting mates and
repelling rivals. Until recently, research on vocal behavior focused almost
exclusively on those loud, flashy vocalizations while largely ignoring the
quiet, whispered sounds produced by many species during close proximity
interactions with a mate or rival. Recent evidence has indicated that these
secretive sounds serve a variety of important functions that affect a bird's
ability to survive and reproduce, and in some cases these songs are even
more complex and impressive than the loud songs produced by certain species.
In this program, Dr. Reichard will reveal this "hidden" vocal repertoire in
a common winter resident of central Ohio, the Dark-eyed Junco. He will
discuss his research that focuses on determining the function and
evolutionary significance of these under-appreciated signals.
