The birds manufacture it. Collection is done by digging.

(Most guano is collected on small islands near Peru and the coast of Peru. Originally it was done by hand. Machinery was adapted to collect and pack it for shipping but the guano reserves were nearly wiped out. It is once again done mostly by hand, through small family holdings. Each concessionaire is limited to how much he can take per season and is required to do much of the work by hand, being the least intrusive method. After ‘harvesting’ an area it is supposed to be left ‘fallow’ for at least a year, which means each concessionaire is required to have a minimum of 2 working plots. Predictably a lot of these rules are broken since a lot poor people depend on the work and a lot of wealthy people are in position to offer bribes. Guano is one of the best and safest fertilizers in use, but is must be aged (naturally fermented which concentrates the nitrogen) a bitand dried before bagging and shipping.
It is produced as it always was. Sea feeding birds drop their excrement on the land where it ferments, and dries out. It can they be easily shoveled up if there is sufficient depth of it. The idea of not working one area 2 years in a row is to allow enough to accumulate to be worked reasonably easily-profitably- by hand. The more efficient machinery tended to scare off the bird populations prevening the useful depositing of the bird ****.

GUANO IS THE MANURE OF THOUSANDS OR MILLIONS OF BIRDS OVER LONG PERIODS OF TIME AND IT COLLECTS ON ROCKS OR EARTH ANCAKES AS IT DRIES. IT CAN ACCUMULSTE SEVERAL FEET DEEP AND BE ALMOST AS HARD AS ROCK. IT IS REMOVED BY HAND WITH PICK AND SHOVEL, OR BY MACHINE IT IS GROUND INTO A UNIFORM SIZE AND PACKAGED FOR SALE.
