The Blue Jay is a passerine bird. It is adaptable, aggressive and omnivorous. Blue Jays can make a large variety of sounds, they can even mimic human speech.

Blue Jays have strong black bills which they used for cracking nuts, and acorns and for eating corn, grains and seeds, although they also eat insects such as beetles, grasshoppers, and caterpillars.

Argan oil is an oil produced from the kernels of the endemic argan tree, which is valued for its nutritive, cosmetic and numerous medicinal properties. The tree, a relict species from the Tertiary age, is extremely well adapted to drought and other environmentally difficult conditions of southwestern Morocco.

Until now argan oil remains one of the rarest oils in the world due the small and very specific growing area.

For centuries before modern times, the Berbers (indigenous people of Morocco) of this area would collect undigested argan pits from the waste of goats which climb the trees to eat their fruit. The pits were then ground and pressed to make the nutty oil used in cooking and cosmetics. However, the oil used in cosmetic and culinary products available for sale today has most likely been harvested and processed with machines.

The oil was sold in Moroccan markets even before the Phoenicians arrived, yet the hardy argan tree has been slowly disappearing. Overgrazing by goats and a growing, wood-hungry local population have whittled the number of surviving trees down to less than half of what it was 50 years ago.
