Over half gone! If half the hummingbirds suddenly died there’d be an outcry like you wouldn’t believe. All the major news media would pick it up. I don’t know whether it’s in the posted story or not but in the interview it was suggested that the spraying of Roundup in the Midwest was partially to blame. Roundup much more effectively obliterates all of the milkweed in an area as opposed to tilling.
But people just don’t care about bugs. Sigh
