Riggle is correct in that birds are not really interestted in grass seed, let alone chipmucks and voles... the seed gets lost in dirt real quick and is not attractive to animals of any sort, until germination... its no different than Sandhill Cranes eating the corn fields for the sprouts... Seed sitting in the ground for years? all of it?? nothing grows for years and the animals will destry it??? I've never seen that happen,,, and I would like to know of anyone who has overseeded/seeded without irrigation and got nothing for years... plz, report those episodes for everyones' benefit... new mythology?? or just another snide attack???
