Seed when castor beans have been ingested by animals. In addition, seeds containing amygdalin—apple, apricot, bitter almond, peach, plum, cherry, quince, and others—when consumed in sufficient amounts, may cause cyanide poisoning. Other seeds that contain poisons include annona, cotton, custard apple, datura, uncooked durian, golden chain, horse-chestnut, larkspur, locoweed, lychee, nectarine, rambutan, rosary pea, sour sop, sugar apple, wisteria, and yew. The seeds of the strychnine tree are also poisonous, containing the poison strychnine. The seeds of many legumes, including the common bean ("Phaseolus vulgaris"), contain proteins called lectins which can cause gastric distress if the beans are eaten without cooking.
Tree swallow as "Hirundo bicolor" by Louis Pierre Vieillot in his "Histoire naturelle des oiseaux de l'Amérique Septentrionale", published in 1807. The genus it is currently placed in, "Tachycineta", was established by Jean Cabanis in 1850. This swallow is sometimes placed in the genus "Iridoprocne", along with the mangrove swallow, white-rumped swallow, white-winged swallow, and Chilean swallow. The placement was first made by Elliott Coues, on the basis of its plumage. The tree swallow is also called the white-bellied swallow, for its white underparts. The generally accepted genus name is from Ancient Greek "takhykinetos", "moving quickly", and the specific "bicolor" is Latin
