Hm. Looks like what the squirrels do in our yard
And I have squirrel nests in my trees.
Anyhow- that big bush that they hopped under? I can bet you've got babies somewhere under there. My neighbors have bunnies that have babies under their porch. AND- they buried babies in a hole (there was some grass over them). How do I know this? B/c my neighbor ran over the nest with his lawn mower! The bunnies weren't hurt at all- in fact my neighbor came running over here and told us to bring the girls over. They were SO cute- and the mama bunny was near the fence.
We back up to woods and I know we've got bunnies in there somewhere. Because they're munching on the lawn
Most of it back there is weeds anyhow- I just make sure that we don't put anything on the weeds back there.
My cats used to bug them. The 17 year old doesn't even chase them anymore. Sneaky will watch them- and we've got to be careful when she's outside-because she will try to get the babies. And I really don't want her chasing them, we get foxes occasionally here too, and they do eat bunnies
