The Field Museum and the Palmer House served as the meeting sites for 650 ornithologists from August 13-17. These were joint meetings of the two largest North American ornithological societies, the American Ornithologists’ Union and the Cooper Ornithological Society. On Tuesday (Aug. 13), three of the five workshops preceding the presentation sessions were held at the museum on topics that included working with egg collections (taught by Linnea Hall and René Corado from the Western Foundation of Vertebrate Zoology) and collecting parasites from birds (taught by Research Scientist Jason Weckstein and colleagues). The presentation and poster sessions were held at the Palmer House from the 13th-17th August. Field Museum staff and students organized four of the meeting’s symposia on topics that included: The Assembly of the North American avifauna (Ben Winger, Committee on Evol. Biology, U. Chicago), How well do we know the Old World tropics? (Research Associate Sushma Reddy and Bird Division Collections Manager Ben Marks), Cowbird brood parasitism: A Uniquely New World Phenomenon (Research Associate Bill Strausburger and colleague Mark Hauber), and Avian Parasites: models for understanding process and patterns of diversification (Jason Weckstein and colleagues).
The 20 presentations and posters presented by researchers associated with The Field Museum are listed down at the bottom and I’m pleased to write that authorship on papers included Filed Museum paleontologist Lance Grande and botanist Rick Ree to illustrate the cross cutting nature of the interactions. Also, one talk (Jennie Lee, U. Chicago) and two posters (by Mark Swanson, Illinois Wesleyan, and Michael Hanson, graduate of Loyola University) were presented by undergraduates or recently graduated undergraduates. The research presented was the result of fieldwork on four continents (North America, South America, Africa and Asia). Many attendees came over to conduct research on specimens in the museum’s Bird Collections.
I chaired the local committee with Mary Hennen, and Peter Lowther took charge of the scientific program. Many other staff, students, and volunteers pitched in. A number of people across the museum including Stephanie Ware (Insects), Mario Avila (Media Services), Ed Czerwin (Print Shop), Tyana Wachter (Action Science), Christine Giannoni (Library), Jean Cattell, Nel Fetherling, Greg Mercer, and Emily Ward (Exhibits) helped with various projects that enriched the meetings. At a late night music event, Sean Bober and his band FulKinetic performed to a delighted crowd. John Weinstein took a wonderful meeting group photo on Saturday evening. The crowning event of the week was a Saturday night banquet in Stanley Field Hall where after their dinner, 330 attendees were treated to the revised Ronald and Christina Gidwitz Hall of Birds, the Green River fossils in Evolving Planet, Restoring Earth: The Abbott Hall of Conservation, and the Daniel F. and Ada L. Rice DNA Discovery Center. The meetings were a scientific success and attendees thoroughly enjoyed everything Chicago and the museum has to offer.
We brought several novel events that we hope might become traditions to these meetings. The first was that through the efforts of Nick Block, we received support from local birding groups to support the attendance of a group of 10 High School Students to attend the meetings for a day. These students came from Illinois, Wisconsin, and Michigan. They got to see talks and meet a number of ornithologists throughout the day.
On Wednesday night we provided popcorn and then screened The Field Museum’s award winning “Passion for Birds” video along with The Ordinary, Extraordinary Junco which was created by Ellen Ketterson, Jonathan Atwell and colleagues at Indiana University. Following the screening we had a panel discussion in which Ellen, Christy Bergeon-Burns (Associate Producer/Director of the Junco project), Kate Webbink (Field Museum Media Producer), and Ed Scholes, Curator of Video, Cornell Lab of Ornithology discussed how to apporach undertaking such projects and how to target audiences. This video event combined with the short video contest arranged by Nick Block and the student affairs committee highlighted this important field of scientific communication. In the future, such activities are likely to become commonplace with avian research projects. This year's short video winner was University of Chicago and Committee on Evolutionary Biology doctoral student Aaron Olsen.
