David Lank – Competition, cooperation, and deceit among three male morphs of ruffs and the females that choose to mate with them: is this the most complex avian mating system?

Ruffs (Philomachus [or Calidris, if you prefer] pugnax) have the most complex mating system of any bird in the world. Three genetically distinct types of males, with different morphologies and mating strategies, attempt to mate at leks with as many females as possible. Most highly ornamented males fight, but others are somewhat cooperative, and small unornamented males mimic female morphology and behaviour. Nearly all ornamented males carry individually distinctive plumage coloration and patterns. How and why did this hyperdiversity in behaviour and morphology evolve, and how does it persist? A chance chromosomal mutation 4 million ago started this unique situation, but it persists through complex social interactions. Uneasy alliances occur between certain males despite their fundamental competition for mates. Although there is strong sexual selection, with many females choosing to mate with particular males and most males mating with none each year, all three morphs and the extensive plumage variation persists. What has thwarted directional selection for one type of male in this case? My talk will cover genetics, development, identity signals, mate choice, and the social behavior that maintains these complex polymorphisms.
David Lank started studying shorebirds during the summer of 1972, when he demonstrated the use of star compasses by migrant semipalmated sandpipers for his undergraduate thesis research at Marlboro College, Vermont. Following a MSc at the University of Minnesota and PhD at Cornell on the behavioral ecology of sandpipers at migratory stopover sites, he joined Lew Oring to study polyandry in spotted sandpipers. In 1984 he began fieldwork on the complex mating system of ruffs, which continues to this day, including work with a captive breeding flock since 1985. Following a decade as a researcher at Queens University, Ontario, he is now at Simon Fraser University, Vancouver BC, Canada, where he has supervised research on the breeding biology of western sandpipers and phalaropes, migration and non-breeding season biology of shorebirds in British Columbia, Mexico and northern South America. His more recent research has emphasized the role of the change in ‘danger landscapes’ brought about by resurgent raptor populations on the migratory and non-breeding biology of shorebirds.
Sarah Hird – Birds and Bacteria: The Avian Microbiome
February 3, 2020
Assistant Professor, Molecular and Cell Biology
University of Connecticut
Microorganisms have existed on this planet for billions of years. They have shaped our world in countless important ways. How have microorganisms affected animal evolution? Birds are a globally important clade of animals that are essential components to nearly all terrestrial and many aquatic ecosystems. Their morphological, ecological and phylogenetic diversity are immense. All birds have microbiomes - the communities of microorganisms that exist on and in birds. Microbiomes performs various functions for their hosts but can also have little or negative effects on host biology. The microbes within the microbiome benefit from their association with a host, but can also be negatively affected. The Hird Lab uses the genomic information of the microbiome and computational methods to address this question: What can the microbiome tell us about birds - and specifically, bird evolution?
Sarah Hird is an assistant professor in the Molecular and Cell Biology department at the University of Connecticut. She is an evolutionary biologist interested in how the microbes that live on and in birds (collectively, the “microbiome”) have affected bird biology and evolution. She received a Master’s degree from the University of Idaho, a PhD from Louisiana State University and was a UC Davis Chancellor’s Postdoctoral Fellow at the University of California, Davis. Outside the lab, she is devoted to diversifying Academia and supporting women in science. Outside Academia, she enjoys playing Legos with her kids.

Sonoran Joint Venture Coordinator
U.S. Fish and Wildlife Service
The southwest United States and northwest Mexico is a region of incredible biological diversity, as well as human diversity. Birds and habitats don't recognize international boundaries, and neither can our efforts to conserve then. Successful conservation requires cross-border collaboration that takes into account not just the biological needs, but also the social needs of the region. The Sonoran Joint Venture is a binational partnership the works to conserve the unique birds and habitats of the southwestern U.S. and northwestern Mexico. Join Dr. Jennie Duberstein, Sonoran Joint Venture Coordinator, to learn how the SJV brings together partners from both sides of the border to develop and implement innovative mechanisms to address the biggest conservation priorities of the region and ensure a healthy landscape for birds, other wildlife, and people.
Dr. Jennie Duberstein is a wildlife biologist and conservation social scientist who has spent her professional career working to build partnerships for bird and habitat conservation across the United States and northwest Mexico. She has directed environmental education programs, developed community-based conservation projects in the U.S.-Mexico border region, developed and taught courses and workshops on bird identification, ecotourism, and bird monitoring, and has studied species including Double-crested Cormorant and wading birds in Sonora and Yellow-billed Cuckoos in Arizona. Jennie has also worked with young birders for many years, directing field courses, summer camps, and conferences, and generally helping to connect young people with opportunities and each other. Jennie received her B.S. in Wildlife Biology from Virginia Tech and her M.S. and Ph.D. from the University of Arizona’s School of Natural Resources and the Environment.
Gabrielle Nevitt – Following the Scent of Avian Olfaction
May 4, 2020
Professor, Department of Neurobiology, Physiology and Behavior
University of California, Davis
When John James Audubon proclaimed that birds lacked a sense of smell, the study of avian olfaction was doomed to suffer ridicule by ornithology text books for years to come. In recent years, ornithologists have renewed their interest into the sense of smell in birds leading to a new appreciation of their chemical ecology. The tubenosed seabirds (petrels and albatrosses) of the order Procellariiformes have among the most impressive olfactory abilities of any animal on earth. Species within this order spend most of their lives flying over the world’s oceans, returning to land each year or every other year, to breed and rear a single offspring. They tend to partner for life and show strong nest-site fidelity between breeding seasons. Much of my research career has focused on elucidating how procellariform species use olfaction to perform behaviors ranging from foraging and navigation to mate choice and individual recognition. My presentation will touch on some of our recent findings and hopefully convince you that olfaction is a rich field of study, and that questions related to sensory ecology are both important and applicable to scientific inquiry into the biology and conservation.
Gabrielle Nevitt is a leader in the field of vertebrate Chemical Ecology and has conducted pioneering research in the sense of smell in birds, focussing on procellariform seabirds. She graduated from Stanford University, received her PhD in Zoology from the University of Washington, and did postdoctoral training in the Department of Neurobiology and Behavior at Cornell University. She has been a professor in the Department of Neurobiology, Physiology and Behavior at UC Davis for 24 years. She lives with her family on a rural property with various birds including emus.
Gail Patricelli – Robots, Telemetry, & the Sex Lives of Wild Birds Using technology to study & protect an enigmatic bird
June 1, 2020
Professor, Department of Evolution and Ecology
University of California, Davis
Animals use a dizzying array of sounds, smells, colors, dances, electrical fields and seismic vibrations to convince each other to mate. These elaborate courtship signals were a mystery until Darwin’s time—after proposing his theory of natural selection, Darwin was left with the question of how the flamboyant peacock could be shaped by the same process that makes the peahen so perfectly camouflaged. There is now strong support for Darwin’s answer to this question, the process he termed sexual selection, proposing that the courting sex must be elaborate because the courted sex demands it. But how can we study the conversations males and females in non-human animals have about mating? One way to do this is to participate, controlling one side of the conversation with a robot. Gail Patricelli will talk about using robotic females and other technology to study courtship behaviors in the greater sage-grouse, and how such research informs conservation of this iconic North American bird and its habitat.
Gail Patricelli is a professor in the Department of Evolution and Ecology at the University of California, Davis. Professor Patricelli and members of her lab study bioacoustics, the evolution of breeding behaviors, and the impacts of noise pollution on birds.
