Being an adult Cicada is a very dangerous life. There are many hazards to avoid from the time they come out of their long underground nymph stage. I often see Cicadas who have escaped a bird attack, sometimes they have a limb missing or damaged wings. The way Cicadas get around the constant threat of bird attack is by having huge populations so they outnumber their prey. But one short flight to freedom can spell the end of a life. Nature seems so cruel, but a bird needs to eat as well.
