    I'm here to reinforce the two comments I found (there are probably more) noting that "passerine" is not the name of a particular kind of bird, but of an entire large category of birds. ("Passerine" means "perching"; the group includes all songbirds.) There is no such thing as "the" New Guinean passerine bird. There are probably hundreds of passerine species in a diverse environment like New Guinea. The papers cited state that SEVERAL New Guinea passerine birds, of two different genera, exhibit the toxin-related behavior. I don't want to be overly critical, but saying "passerine" over and over as if it were the name of a specific bird -- on a science show -- is the sort of mistake that should have been caught by whoever does your quality control.

  • Mojos Bigstick

    'Passerine' isn't a species of bird - it's a whole Order - there are loads of different species, all over the world, that are described as Passerine. Your phrasing suggests it's one particular bird species.

    I feel like you kind of missed an oppurtunity to point out that aside from stealing toad toxins, the tiger keelback is also unique in having both it's own venom as a rear fanged colubrid in addition to storing toad toxins for self-defense thus making it both poisonous AND venomous.

    The New Guinean passerines you're talking about are more specifically members of the Pitohui genus which consists of Old World orioles, as well as the Blue-capped ifrita which is in a genus of it's own. A passerine /ˈpæsəraɪn/ is any bird of the order Passeriformes (/ˈpæsərɪfɔːrmiːz/, Latin passer (“sparrow”) + formis (“-shaped”)), which includes more than half of all bird species.

    "New Guinean Passerine birds"??? The birds are called Pitohuis! (Pitohui dichrous is the one in the video) Of course they're passerines, they're in the order Passeriformes, the largest and most diverse order of birds! C'mon SciShow!
