Snad Hill Cranes (Sandys) were used here in Florida as substitute parents to Whooping Cranes. Cranes will lay another egg if the first is taken soon after laying. This makes possible using the first egg to double the annual reproductive rate but twice the number of parents are needed - enter the Sandys.
It works. In Brandon, Fl a pair of Sandys was raising a Whooper when the Gubment AgencyPersons had to intervene. Seems the Sandy parents were taking their Whooper juvenile to construction sites AT LUNCHTIME!
Mr & Mrs Birdbrain were smart enough to realize when the equipment stopped moving and the featherless bipeds got off, all they had to do was walk up and part of construction worker lunches was offered.
If one wants lots of any critter like birds, put the issue up for bids. Hatchery owners can raise any number of birds the market will pay for, and will also condition the birds for a fee. Better, faster, and cheaper than AgencyPersons, too.
Sand Hill Cranes were once numerous, were shot down to very low levels, and have rebounded to the extent there is(and should be) a hunting season.
Same could be for Whoopers.
What does America want, AgencyPersons or Whoopers?
Thanks for the input. Interesting.
