Well ducks at >90/second and chickens at >1500/sec doesn't quite compare with 15/second. How do you figure 15/second is about right anyway?

An estimate of 1/2 to 1B birds dying per annum. But that was only due to human interaction (freeways etc).

Yeah but chickens - that given number corresponds to 50B per year. But there are more than 65B (though less than 20B at any one time exist).
