I’m so glad we see birds in their migration paths. We went to Point Pelee last year and saw some, but I think it’s even nicer to see the birds here. One thing you don’t have to deal with is the crowds.
The challenge is to identify these little birds as they travel through. The warblers move so quickly through the trees that it’s hard to identify them. This site has been a big help: http://www.whatbird.com/
One thing I noticed in my research that was interesting is that they often use porcupine quills for material for their nests.
