Canopy

Here is the green canopy created by the Wild Castor bean(Ricinus communis) leaf. Naturally back lit by sunlight. You can also notice a ladybird beetle at the center of the image.

The castor oil plant, Ricinus communis, is a species of flowering plant in the spurge family, Euphorbiaceae. It belongs to a monotypic genus, Ricinus, and subtribe, Ricininae. The evolution of castor and its relation to other species is currently being studied. Its seed is the castor bean which, despite its name, is not a true bean.

Castor seed is the source of castor oil, which has a wide variety of uses. The seeds contain between 40% and 60% oil that is rich in triglycerides, mainly ricinolein. The seed coat contains ricin, a toxin, which is also present in lower concentrations throughout the plant.

The toxicity of raw castor beans due to the presence of ricin is well-known. Although the lethal dose in adults is considered to be 4 to 8 seeds, reports of actual poisoning are relatively rare. According to the 2007 edition of the Guinness Book of World Records, this plant is the most poisonous in the world.

Castor seeds have been found in Egyptian tombs dating back to 4000 BC being used mostly to fuel lamps because of the slow burning oil. Herodotus and other Greek travelers have noted the use of castor seed oil for lighting, body ointments, and improving hair growth and texture. Cleopatra is reputed to have used it to brighten the whites of her eyes. The Ebers Papyrus is an ancient Egyptian medical treatise believed to date from 1552 BC. Translated in 1872, it describes castor oil as a laxative.

Global castor seed production is around 1 million tons per year. Leading producing areas are India (with over 60% of the global yield), China and Brazil.

White-rumped Munia

White-rumped Munia

White-rumped Munia

The White-rumped Munia or White-rumped Mannikin (Lonchura striata). These are close relatives of the true finches (Fringillidae) and true sparrows (Passeridae).

The White-rumped Munia is approximately 10 to 11 cm in length, with a stubby grey bill and a long black pointed tail. The adults are brown above and on the breast, and lighter below; the rump is white. This is theLonchura striata striata (Linnaeus, 1766) subspecies – Southwestern White-rumped Munia found in Southern Indian mainland. It has Dark chocolate-brown above, white below.

The White-rumped Munia is a common resident breeder ranging from South Asia to southern China east to Taiwan, and through Southeast Asia south to Sumatra; it frequents open woodland, grassland and scrub, and is well able to adapt to agricultural land use. It is a gregarious bird which feeds mainly on seeds, moving through the undergrowth in groups and sometimes accompanying other birds such as Puff-throated Babblers (Pellorneum ruficeps). The nest is a large domed grass structure in a tree, bush or grass into which 3-8 white eggs are laid.

It is a common and widespread bird across its large range, and is thus not considered a threatened species by the IUCN. In fact, it may locally become a nuisance pest of millets and similar grains. Even the Nicobar Islands subspecies with its limited range seems to be able to cope well with human settlement. As it is a drab-colored and rather reclusive bird inhabiting dense undergrowth, the White-rumped Munia is not necessarily conspicuous even where it occurs in considerable numbers.
