Batrachotoxins, including many congeners not previously described, were detected, and relative amounts were measured by using HPLC-mass spectrometry, in five species of New Guinean birds of the genus Pitohui as well as a species of a second toxic bird genus, Ifrita kowaldi. The alkaloids, identified in feathers and skin, were batrachotoxinin-A cis-crotonate (1), an allylically rearranged 16-acetate (2), which can form from 1 by sigmatropic rearrangement under basic conditions, batrachotoxinin-A… 

Figures and Tables from this paper

Melyrid beetles (Choresine): a putative source for the batrachotoxin alkaloids found in poison-dart frogs and toxic passerine birds.
TLDR
The presence of high levels of batrachotoxins in a little-studied group of beetles, genus Choresine (family Melyridae), and their high toxin concentrations suggest that they might provide a toxin source for the New Guinea birds.
The batrachotoxins with a protective function in birds
TLDR
Toxicity in vertebrates has usually been associated with venomous snakes, some fish species and also the so-called arrowy frogs, but relatively little known that these arrow poisons from the batrachotoxin group are also present in the skin and feathers of some bird species from the genus Pitohui and Ifrita, living in the New Guinean primavean forest.
Heteropteran chemical repellents identified in the citrus odor of a seabird (crested auklet: Aethia cristatella): evolutionary convergence in chemical ecology
TLDR
It is suggested that the auklet odorant functions as an ectoparasite repellent and a signal of mate quality, one of several putative bases for mate selection in birds.
The role of toxic pitohuis in mixed-species flocks of lowland forest in Papua New Guinea
TLDR
This study provides the first empirical test of the connection between toxicity and flock organisation in PNG and primarily negative results suggests that toxicity does not drive the organisation of flocks in the study area.
Skin as a Toxin Storage Organ in the Endemic New Guinean Genus Pitohui
TLDR
The skin of Hooded Pitohuis appears to have typical dermal and epidermal morphology, and it is speculated on possible ways in which this species may sequester and secrete toxins using typical avian skin structural features, unique among vertebrates.
Toxicity and Alkaloid Profiling of the Skin of the Golfo Dulcean Poison Frog Phyllobates vittatus (Dendrobatidae)
TLDR
This study provides the first experimental data on the toxicity and associated symptoms in mice, as well as the chemical profile of the skin of P. vittatus, an endemic species from the Southeastern Pacific region of Costa Rica, and suggests that the skin alkaloids ofP.
Phylogeny of the avian genus Pitohui and the evolution of toxicity in birds.
Kopalne ssaki jadowite z nadrzędu Eulipotyphla
TLDR
This paper reviews the fossil Eulipotyphla which are suspected to produce a venom and presumed ability of producing venom in above-mentioned species is based on special dental features, such as incisors (or canines of Nesophontes) provided with a deep groove enabling delivery of venom from salivary glands, and relatedness to the extant venomous Eulipsia.
Polyphyletic origin of toxic Pitohui birds suggests widespread occurrence of toxicity in corvoid birds
TLDR
It is shown that Pitohuis, rather than being a tight-knit group, are polyphyletic and represent several lineages among the corvoid families of passerine birds, demonstrating that the ability to be toxic is widespread among corvoid birds and suggesting that additional members of this radiation, comprising more than 700 species, could prove to be Toxic.
Chemical investigations of defensive steroid sequestration by the Asian snake Rhabdophis tigrinus
Rhabdophis tigrinus is an Asian natricine snake that possesses unusual defensive glands on the dorsal surface of its neck. These nuchal glands typically contain cardiotonic steroidal toxins known as

Homobatrachotoxin in the genus Pitohui: chemical defense in birds?
TLDR
Three passerine species in the genus Pitohui, endemic to the New Guinea subregion, contain the steroidal alkaloid homobatrachotoxin, apparently as a chemical defense, suggesting that birds and frogs independently evolved this class of alkaloids.
Levels of batrachotoxin and lack of sensitivity to its action in poison-dart frogs (Phyllobates).
TLDR
The regulatory site controlling sodium-channel activation and permeability appears to have been minimally altered to prevent interaction with batrachotoxin, but is still sensitive to other sodium conductance activators (veratridine, grayanotoxin) to which the frogs are not exposed naturally.

EVOLUTION OF TOXICITY IN PITOHUIS: I. EFFECTS OF HOMOBATRACHOTOXIN ON CHEWING LICE (ORDER PHTHIRAPTERA)
TLDR
Results suggest that homobatrachotoxin repels and kills lice and may thus protect pitohuis against lice infestation.
Birds of New Guinea
TLDR
This book is the first definitive ornithological field guide to New Guinea and treats all of the more than 700 species of birds recorded from the region, illustrating more than 600 of them in forty-seven fine color plates and eight black-and-white halftone plates.
The Mottled-breasted Pitohui Pitohui incertus
TLDR
P. incertus may associate with mixed flocks of babblers, other pitohuis, drongos and birds-of-paradise and its plumage and call may be conver- gent with those of some other members of these flocks.
Batrachotoxin: Chemistry and Pharmacology
TLDR
The subsequent effects of this increase in Na+ permeability evoked by batrachotoxin—such as membrane depolarization, enhanced spontaneous transmitter release, muscle contracture, and enhanced formation of cyclic AMP in brain slices—may be blocked reversibly by tetrodotoxin.
