Bird Studies From Banding

by Lee Johnson

Lee Johnson has first-hand experience that comes from years out in the field.  Lee started Sand Bluff Bird Observatory in northern Winnebago County in 1967.  The all-volunteer organization has banded over 300,000 passerines and raptors.  The data generated over 49 years of banding in the same place is important.  It shows what is happening with bird populations over time.  There are people who do not “believe” in global climate change, but bird banding data shows that many of the migrating birds and nesting birds are shifting their historic locations.  Lee will talk about some examples which the banding has shown, including Indigo Bunting, Gray Catbird, Fox Sparrow, and Tennessee Warbler. He will also give examples of unusual retraps from other countries, and longevity records from retraps.  

FREE!  Wonderful desserts and snacks during social at 7PM until 7:20PM.  

Please, bring your friends and family!
