Which is relevant how? Ticks, fleas, rats, bedbugs cockroaches, leeches and tapeworms would perfectly unobjectionable if they didn’t choose to hang out with us. Seagulls, pigeons, racoons, foxes and other critters become vermin when they move into urban environments and breed into huge populations existing on a diet of refuse, doing massive property damage and spreading disease. Ditto for rats, mice and so on.
Yeah but a lot of those are actual parasites. And dangerous. Whereas pigeons are…birds. Without them there wouldn’t be much of an avian life in urban areas. And a place without birds is just depressing. So we have to take what we can get.
I also think seagulls are glorious birds (to quote Ruth Gordon…or Dreyfus.)
Hmmm… A city without rats, mice, cockroaches and pigeons sounds just fine to me. And trust me, seagulls are a lot less fun once you’ve helped someone clear their guttering of six months worth of seagull-regurgitated plastic, bones, hair, gristle etc. In summer.
