Subject: IBET ENSBC Program Meeting Tuesday - How Birds Make Colorful Feathers (NO SIGHTINGS)
The Evanston North Shore Bird Club will meet this Tuesday, September 26, for a program on “How Birds Make Colorful Feathers, and Why It Matters”.
In addition to flight, birds must use their feathers to keep warm, stay dry, hide from predators and attract mates. Colorful signals like the eyespots of a peacock are among the most diverse traits in nature, and several groups of birds differ only in their plumage colors. Inspired by this dazzling array of colors, Chad Eliason from the Field Museum uses a combination of physics and modern comparative methods to tackle pressing questions in biology, including: How do birds produce colorful signals? What do other birds see in a signal? And, what are the forces driving changes in color through time?

The meeting begins at 7:30 p.m. at the Evanston Ecology Center, 2024 McCormick Boulevard (corner of Bridge Street) in Evanston.
