This is not a purely academic question.
I was at Niagara Falls today. As I was right at the rail near the top of Horseshoe Falls, I saw a bird floating on the water. I’m guessing it was a cormorant, and it had a fish (sardine-class) in its mouth. I watched it float right to the edge of the Falls, and then go over, but I couldn’t see what happened after that.
This raised several questions in my mind.
Can a cormorant fly with a fish sticking out of its mouth, and probably battling some serious downdrafts?
Are there a lot of small fish in the Niagara River, and in the fast-flowing water at the top of the Falls?
If the answer to #2 is ‘yes’, what happens to those fish who go over the edge? If the cormorant hadn’t eaten this fish, was it only going to live another three seconds?
