“…Bufotenine and other tryptamine derivatives are principle constituents of the parotid gland secretions of New World toads belonging to the genus Bufo, for which the compound was named when first isolated. Curiously, DMT or 5-MeO-DMT has not been reported from any Bufo species, with a single exception: Bufo alvarius, which contains 5-MeO-DMT instead of bufotenine; rather staggering concentrations of up to 10 % dry weight of the parotid gland have been reported by some investigators (Daly and Witkop 1971;Weil and Davis 1994).…”

New World indigenous peoples are noted for their sophisticated use of psychedelic plants in shamanic and ethnomedical practices. The use of psychedelic plant preparations among New World tribes is far more prevalent than in the Old World. Yet, although these preparations are botanically diverse, almost all are chemically similar in that their active principles are tryptamine derivatives, either DMT or related constituents. Part 1 of this paper provides an ethnopharmacological overview of the major tryptamine-containing New WorldNew World hallucinogensHallucinogens .

“…Black kites have a large geographic distribution in Africa, Asia, and Europe where other species of toads naturally occur, while whistling kites have a more limited range (Australian and parts of Papua New Guinea). Bufotoxins of different toad species are chemically similar (Chen and Chen 1933;Daly and Witkop 1971;Meyer and Linde 1971) and thus coevolution with other toad taxa may have preadapted Australian raptors to dealing with the poisons of cane toads.…”

Toad’s tongue for breakfast: exploitation of a novel prey type, the invasive cane toad, by scavenging raptors in tropical Australia

Although interest in the ecological impacts of invasive species has largely focused on negative effects, some native taxa may benefit from invader arrival. In tropical Australia, invasive cane toads (Bufo marinus) have fatally poisoned many native predators (e.g., marsupials, crocodiles, lizards) that attempt to ingest the toxic anurans, but birds appear to be more resistant to toad toxins. We quantified offtake of dead (road-killed) cane toads by raptors (black kites (Milvus migrans) and whistling kites (Haliastur sphenurus)) at a site near Darwin, in the Australian wet-dry tropics. Raptors readily took dead toads, especially small ones, although native frogs were preferred to toads if available. More carcasses were removed in the dry season than the wet season, perhaps reflecting seasonal availability of alternative prey. Raptors appeared to recognize and avoid bufotoxins, and typically removed and consumed only the toads' tongues (thereby minimizing toxin uptake). The invasion of cane toads thus constitutes a novel prey type for scavenging raptors, rather than (as is the case for many other native predators) a threat to population viability.
