More than 10.5 MILLION birds crossed Charleston County in just three nights. 🤯🐦
While most of us were sleeping, an incredible wave of fall migration was unfolding overhead.
BirdCast estimated 2,767,000 birds Thursday night, 5,362,800 Friday night, and another 2,454,300 Saturday night crossing Charleston County — bringing the three-night total to an estimated 10,584,100 birds.
So what did all of that migration look like on the ground?
I headed out to Sullivan’s Island to find out. By morning, migrants were moving through the maritime forest, including warblers and other songbirds making their way south for the fall.
It’s pretty incredible to think that while Charleston is sleeping, millions of birds can be moving through the darkness above us — and by morning, some of them are right here in our parks, forests and backyards.
I wrote about the experience, the BirdCast numbers, and what I found on the ground in the newest Holy City Birding blog.
