All Events
From guided bird walks to interactive learning sessions and meetings, the Champaign County Audubon Society offers a variety of regular events throughout the year (although we typically take off the summer!).
Monthly Program: Bird Health During Migration
Overview:
Migration is one of the most taxing periods of a bird’s annual cycle. My presentation will focus on how blood metabolites (glucose, ketones, triglycerides) reflect migration strategies and body condition (fat and muscle) during spring and fall migration. This project determined baseline blood metabolite levels for six study species, how those correlated with fat and muscle, and how migration strategies influenced the overall condition of migratory birds.
About our Speaker:
Tara Beveroth is an associate avian ecologist at the Illinois Natural History Survey Prairie Research Institute of the University of Illinois at Urbana-Champaign.

Monthly Program: TBD
Overview:
Urban areas along migration routes pose significant risks to migratory birds due to threats that include building collisions and light pollution.

Monthly Program: How Our Noise Affects Red-winged Blackbird Parents
Overview:
Noise pollution is an increasingly pervasive environmental challenge, with demonstrated effects on animal communication and behavior. For Red-winged Blackbirds (Agelaius phoeniceus), male parents providing food is largely influenced by auditory cues from nestlings. I studied whether noise from highways interfered with male provisioning behavior by masking auditory signals from nestlings. These results may also offer insight to highway departments, urban planners, and developers of other human-made structures in designing and routing infrastructure to reduce the effects of noise pollution on wildlife.
About our speaker:
Angelina Roman-Alcocer is a senior in integrative biology at the University of Illinois Urbana-Champaign and has been participating in research since her freshman year.
