Mürkpeoleo (Pitohui) on Uus-Guineal levinud värvuliste perekond. Perekonda kuulub neli liiki.

Mürkpeoleod on omnivoorsed linnud. Mõnede mürkpeoleode, eriti Pitohui kirhocephalus ja Pitohui dichrous nahk ja suled sisaldavad tugevaid neurotoksilisi alkaloide batrahhotoksiini rühmast. Arvatakse, et see on lindude keemiline kaitse ektoparasiitide või välisvaenlaste (maod, röövlinnud või inimesed) vastu. Mürkpeoleode organism tõenäoliselt batrahhotoksiini ise ei tooda. Tõenäolisemalt saavad nad toksiini ühest oma toiduallikast – Choresine perekonna mardikatest [1] (Dumbacher, et al., 2004).

Paapua uus-guinealased kutsuvad mürkpeoleosid nende halva söödavuse pärast prahilindudeks, keda saab toiduks tarvitada alles pärast sulgede ja naha eemaldamist, liha katmist puusütega ja viimastel praadimist (Piper, 2007).
