Red Crossbill

Loxia curvirostra

Its bill tips really do cross, which lets it pry seeds out of pine cones, and its scientific name says so twice: Loxia means 'crosswise' and curvirostra means 'curved bill.'

Loxia comes from the Greek loxos, 'crosswise'; curvirostra joins the Latin curvus, 'curved,' and rostrum, 'bill.'
