For the past few days I have amused myself feeding an osprey. He shows up just before I hand feed the BG. He takes advantage of the confusion & distraction of the BG when I throw the feed & gets himself dinner. First day he took 5 attempts before he got dinner on the 6 try. Last night first strike & he was headed home with a BG dinner.
I think you need to give that osprey a complimentary subscription to Pond Boss!
With a little more education, you can probably teach him which fish need to be culled from your pond.
