So I guess my next question is: what is the replacement rate? Because 2.6B dead a year from a single source when there is only about 10B alive at any one time, AND that 26% annual death not being the highest cause of bird mortality (e.g. >>26% of all birds die a year), then that means there are a lot of bird babies and a lot of bird corpses out there. The stats are a bit mind boggling for me.
