Insects, squirrels, deer, turkey, small rodents, and birds consume many acorns. They can eat or damage a high percentage of the acorn crop in most years and essentially all of it in poor seed years. Black oak acorns from a single tree are dispersed over a limited area by squirrels, mice, and gravity. The blue jay may disperse over longer distances.
No, this isn't an article written for (or by) squirrels – humans can actually eat acorns under certain circumstances. The nuts stem from oak trees, and can actually elicit a mild, nutty flavor.
Yes, the article speaks of "acorn-leaching" and has this language, "acorns were harvested, peeled and soaked in natural or artificial ponds for several days to remove tannins, then processed to make acorn cakes", but it is not clear whether acorns can be eaten, why they can't be eaten, or how to prepare them if they are to be eaten.
The acorn contributes to the overcup oak's common name. The acorns are almost entirely covered by their cup, hence the name overcup. [3] The cup has gray, pubescent scales. The acorns also have a unique spongy shell that make them buoyant. [8] The pericarp of overcup oak acorns is unusually large for oaks and makes up 50% of acorn mass.
[64] [65] An exception is the domestic pig, which, under the right conditions, may be fed entirely on acorns, [66] and has traditionally been pastured in oak woodlands (such as the Spanish dehesa [67] and the English system of pannage). [68] Humans can eat acorns after leaching out the tannins in water. [69]
The woodpeckers then collect acorns and find a hole that is just the right size for the acorn. As acorns dry out, they are moved to smaller holes and granary maintenance requires a significant amount of the bird's time. The acorns are visible, and a group defends its granary against potential cache robbers like Steller's jays and western scrub ...
Acorns that germinated in the fall were shelled and pulverized before those germinating in spring. [citation needed] Because of their high fat content, stored acorns can become rancid. Moulds may also grow on them. The lighting of ground fires killed the larvae of acorn moths and acorn weevils by burning them during their dormancy period in the ...
These do not reach the acorn's embryo and are healed by the plant, sealing the holes and protecting the eggs from parasites. Upon hatching, either one or two larvae consume the fruit. While they may eat the entirety of the acorn, the larvae typically do not consume the embryo itself. [5] Curculio glandium live throughout winter in the larval ...
