“Irrepressible” certainly applies to rabbits—chipmunks too, come to think of it—but late April into May seems to belong to the rabbits. These two did not budge when I came out with safflower seeds for the finches.
More recently, I have seen a small bunny, offspring I am sure, darting between hostas. It would be lovely if these rabbits would develop a taste for lawns. The height they mow the blue fescue to would be OK with me.
