Wow guess they didn't have cats or dogs. If mine kill some little critter, they check back in the same spot about 10 times a day for days on end to see if another little critter's going to appear there.
:) Or if ours sees a deer...she goes out there every single day and looks towards the same spot. :) We had a couple coyotes the other day and now she goes into the yard and looks that same direction and barks. :)
The Hummingbirds are unique creatures and so very beautiful. We look forward to their arrival every year and we are saddened when they depart in the fall. :)
