This would make mole far too crowded, tbh there should be a better way to obtain nests.
07 Wiki: The chance of getting a bird's nest from a tree is 1/256 each time you would normally get a log, regardless of the type of tree (except redwood trees, which only drop clue nests). Players who equip a woodcutting cape will have an additional 10% chance of receiving bird nests.
I think it'd be okay to lower this rate to fit Alora's needs. Either way, I support this.
