Probably not. People love bluebirds. But there is a potential contender that may meet that only in Idaho test. American Ornithological Society publishes and annual checklist for birders. There are often a few changes on that list, and this year one of those changes is about the South Hills or Cassia Crossbill.
Crossbills are birds that look like they’ve been in a fight where someone knocked their beaks sideways. Their bills—this may not surprise you at this point—cross. This has nothing to do with avian pugilism. It’s a result of evolution. Each crossbill’s beak has evolved to match the particular shape of local pine cones. This didn’t happen overnight. Scientist think this particular bird has been around for about 6,000 years feasting off pine cones in the South Hills, and only in the South Hills of Idaho.
