Point Pelee National Park juts out into Lake Erie like a finger, as every spring thousands of birds touch down on it. It’s a key stop along their migratory routes from the southern U.S., Central and South America to northern Canada.

But climate change has been shifting the conditions of migration, making it harder for some birds and ultimately affecting bird populations, which are already in steep decline. Decibel host Menaka Raman-Wilms, producer Rachel Levy-McLaughlin and Globe and Mail columnist Marcus Gee headed to Point Pelee to see spring migration up close.

A special thanks to Matt Fuirst and Birds Canada, and, as well as, the Cornell Lab of Ornithology, who provided some sounds from their Macaulay Library in this episode.
