Virtual - Kirtland's Warbler versus the Brown-headed Cowbird - An Evolutionary Arms Race

6-7pm CST, May 7th, Online via Zoom
Registration is required for this program. 

(For everyone) Come join as we explore the life history of the Brown-headed Cowbird and how its presence in the Midwest has affected vulnerable bird populations, especially that of the Federally Endangered Kirtland’s Warbler. Join the Urban Ecology Center's very own - Lucero Serna who has helped study the impact that Brown-headed Cowbirds pose to the small breeding population of Kirtland's Warbler in Wisconsin. We will go over the unique adaptations of the Cowbird, what adaptations other bird species have developed to overcome Cowbird parasitism, and why birds in the Midwest may be at a disadvantage. You will not want to miss this lecture on one of the most fascinating evolutionary arms races of all times!
