Three-part speaker series explores new ideas and science presented by ornithology and evolutionary biology experts
DENVER – The Denver Museum of Nature & Science and the Bird Conservancy of the Rockies announce the 2016 speaker series “Birds of Change: Adaptation, Survival and Our Changing World.” All presentations will be held at the Museum.
Nov. 7, 7 p.m., Phipps Theater
Christopher C. Witt, associate professor in the Department of Biology and curator of birds at the Museum of Southwestern Biology at the University of New Mexico, and his colleagues are studying how the genes of birds are adapted to the elevations at which they live. Witt will showcase fascinating discoveries involving hummingbirds and other species that have significant implications for the persistence of montane birds under climate warming. His work will be featured in an upcoming episode about hummingbirds on ”Nature” on PBS, airing Oct. 12, and available for limited online streaming after that date at http://www.pbs.org/wnet/nature/.
Avian Biodiversity Today
Nov. 15, 5:30 or 7:30 p.m., Gates Planetarium
Travel throughout the Americas and explore how environmental changes affect avian biodiversity. Garth Spellman, curator of ornithology at the Denver Museum of Nature & Science, takes you to Central America to see how global cooling during the Pleistocene allowed house wrens to become the species with the largest range in all of the Americas, from southern Chile to the Canadian subarctic. Soar above the Rocky Mountain and western North America to examine how these same ice ages enabled new species to spread across this dynamic landscape, and to the Black Hills of South Dakota, where Virginia’s warbler has recently expanded its range. Conclude with a discussion of how current global warming is affecting birds.
How Mother Bluebirds Shape Ecological Communities
Nov. 29, 7 p.m., Ricketson Auditorium
Renée Duckworth, associate professor in the Department of Ecology and Evolutionary Biology at the University of Arizona, made the incredible discovery that bluebird mothers transmit information to their offspring by altering hormones in their eggs, producing a feedback loop between the mother’s experience, offspring behavior and community change. Duckworth studies how competition for nest cavities among bluebirds in fire-affected landscapes is leading to subtle but measurable changes. Join her to explore these findings and others that are shaping
our understanding of how avian communities change over time.
