I usually head to Point Pelee National Park if I want to see lots of spring migrants but there are other places in the Windsor region that can be very productive for birding. One relatively unknown location is the Big O Conservation Area on the outskirts of Comber.
Woodlots are few and far between in this part of the county which is devoted to growing corn, soybeans and winter wheat. Woodland birds have very few choices on where to rest and search for food during migration and this small patch of swampy woodland can be full of migrant birds in May. This "migrant trap" was alive with birds last weekend yet I was the only birder present. Here are a few of the birds present that day.
Yellow-rumped (Myrtle) Warbler
Black-throated Blue Warbler
