Update:
Well it seems after I went to the trouble tomake Buck Winter Quarters, he seems to have decided to depart under his own wing power (6 foot fence around his poolside home)
He was hanging out by the door on Sat night quacking away to come inside. Sunday Morning he was not there buit that si normal as he like to camp under the shrubs. Sunday Eve at feeding time, No Buck coould be located. No evidence of foul play by the evil squirrel population or by the neighborhoood Red Tailed Hawk.
Perhaps he was upset I went Sailing without him? Or he just decided to head south.
Keep an eye out for him.....I'm sure if he sees R/C sailboats he will stop by for some companionship
