It may seem like all the recent mass bird deaths add up to catastrophic numbers of animals killed, but compared to how many birds are killed every year in ones and twos as they collide with buildings, towers, et cetera, it's a drop in the bucket. Mongabay quotes American Bird Conservancy's president Mike Parr, who gives some important context:Parr says up to one billion birds are killed each year from hitting buildings, another billion get killed by kitty, 50 million die hitting communication towers, 15 million die from pesticide poisoning.
The weird weather involved in perhaps half of the recently reported mass animal death incidents is certainly notable--a conservative calculation based on published reports shows maybe 50,000 birds, bats, fish and manatees have been killed and most of those aren't birds--but the human built environment still is much, much larger threat.
