Your points are quite reasonable. Unless such individuals are very good at
surviving by themselves for a long time until they encounter an elegible
partner, there needs to be simultaneous release of enough birds to survive
initial losses. Most such things are released or escape singly. A few years
ago I observed an exception, a pair of Fischer's Lovebirds (Agapornis
fischeri) near my house in Canberra. A Pied Currawong, then a group of them
was displaying quite an interest in them and the two parrots seemed quite
unable to detect the threat. Eventually one of the Lovebirds flew away with
a Currawong following. I don't know what happened.
