She killed one of the original babies

Well, they don't call her "cowbird" for nothing! Raise your own damn children!

@EuropeanGuy87 It is possible the frequently parasitized species developed the ability to fend off parasite egg or chick, but that ability could lead to infanticide. But the death of the host's own chicks when the nest is no longer parasitized could be caused by limited food supply.

@ifurkend I did remove the 2 parasite eggs which were white with black sport, and left the 4 green ones..and I wen to the nest every 3 days or so..The 4 chicks all hatched successfully, however 4 days after there was only 1 chick left in the nest. I don't understand why, because there was no parasite egg, and I carefully fallowed them until they hatched. It is possible the red winged bird kicked them out cause the next was so small for all the chicks.. I don't know what happened.. who knows.
-
@EuropeanGuy87 I know how you feel for the host, but the mafia hypothesis suggests that the cowbird mothers will still be observing the parasitized nest. If they find out their eggs are removed, they might destroy the other eggs or even the whole nest as a punishment or warning to the host.

so this is what birds to on 420...

Amazing that they have no real mothering left after laying the egg and pecking off the others.

Right today I found 2 cowbird eggs in a red winged black bird's nest... and I removed them of course.. The red winged bird already had 4 of her own, I don't think it's fair ! she worked hard on the nest.. Now I read on internet that the cowbird may destroy the host eggs if she comes back and see her eggs removed :((((

While it may just be in the cowbirds DNA to do this it is in my DNA to shoot every single one I see at my feeder and in my yard as a result my songbird population is booming now. I also terminate blackbirds and house sparrows. The problem with the cowbirds parasitic nesting habit is it adds to their population while taking away from songbirds population and the host mother can't take care of it's own young due to the insatiable appetite of these birds.
