On Tuesday evening, December 10th, 2019 the Linnaean Society of New York 
2019/2020 Speaker Program will feature two new presentations sure to be of 
interest to New York birders:

6:00 pm — Vulture: The Private Life of an Unloved Bird – Kathleen Fallon
Vultures are often overlooked, underappreciated, and unloved, despite the vital 
role they play in healthy ecosystems. Worldwide, vultures are more likely to be 
threatened or endangered than any other group of raptors, but in the United 
States, Turkey and Black Vultures may be increasing in number. This 
presentation will discuss the life and times of the noble Turkey Vulture, 
including its feeding, nesting, and roosting habits, migratory behaviors, and 
common misconceptions.
Katie Fallon is also the author of Cerulean Blues: A Personal Search for a 
Vanishing Songbird (2011), which was a Finalist for the Reed Award for 
Outstanding Writing on the Southern Environment. Katie has taught creative 
writing at Virginia Tech and West Virginia University, and teaches in the 
low-residency MFA programs at Chatham University and West Virginia Wesleyan 
College. She is a founder of the nonprofit Avian Conservation Center of 
Appalachia as well as current President of the Mountaineer Chapter of the 
National Audubon Society.
7:30 pm — Dancing Birds, Sexual Selection, and the Evolution of Cooperation in 
a Tropical Forest – Emily DuVal
Males of many species engage in fierce competition for mates. This competition 
can take the form of intense battles with rivals or flashy displays that 
attract females, but in just a few species, males do something truly unusual: 
instead of competing, they cooperate. Male Lance-tailed Manakins form long-term 
two-male partnerships and display together for females, but only dominant 
“alpha” males mate with the females a pair attracts. Why do males cooperate, 
and what are females looking for, anyway? Drawing on 20 years of empirical 
research into Lance-tailed Manakin cooperation and mate choice, DuVal will 
explore the astounding behaviors that have resulted from intense sexual 
selection while questioning long-held assumptions about how sexual selection 

Emily DuVal first became involved in ornithological research in college, 
collecting data on Great-tailed Grackle mating systems. Following graduation 
from Rice University, she traveled as a Watson fellow to study conflicts 
between conservation and cultural traditions in Guyana, Australia, and New 
Zealand. She studied Lance-tailed Manakins for her doctoral research at the 
University of California, Berkeley, then did postdoctoral at the Max Planck 
Institute for Ornithology in Seewiesen, Germany. DuVal is now an Associate 
Professor at Florida State University.
Both presentations are free and will be held in the Linder Theater on the first 
floor of the American Museum of Natural History <x-apple-data-detectors://7> in 
New York City. Enter at West 77th Street <x-apple-data-detectors://8> between
