[rec.birds] Interesting Osprey Adventure

jla@inuxd.UUCP (Joyce Andrews) (04/02/88)

I am a volunteer at the local wild bird rehabilitation center.
We take in injured WILD birds and give them food, shelter, and
medical care and try to rehabilitate them for release back to the
wild.  Some, of course, can't be released because of amputations
of wings that are so badly messed up they will never support the
bird again.  There is much controversy among societies whether
those birds should be euthanized or kept in captivity.  This
kposting is not to get into that question.       

Anyway, the Florida wildlife folks brought us an osprey that had
fledged too soon and couldn't fly, probably because the nest was
crowded with several other offspring and she got shoved out.  We
put her in the flight cage with another osprey that was hit by a
car and may never be released.  They got along very well.
Yesterday the wildlife folks came to pick up the fledgling.  They
took her back to near where she had been picked up and where they
had selected a foster nest.  The nest they selected was in the
bay shallows, in a mangrove, very low for an osprey nest.  Two
parents and one offspring lived in the nest.  We placed our
fledgling into the nest (after Mom, Dad, and brother/sister flew
away, whistling their disapproval) and left her.  We also put a
few fish in the nest.  She flew away for a short while, but came
back to the nest after we were well away.  A wildlife employee is
watching the nest during daylight hours.  The family has accepted
their new offspring well, and they are confident that the parents
will teach her to fish and she is now a wild bird again.

It surprised me that getting the parents to accept an offspring
was that easy.  I have much farm experience, and I remember how
tough it is to get a female horse or cow or dog or sheep, etc, to
accept another offspring.  While it can be accomplished, it is
nowhere near as easy as the experience with the osprey.  The
wildlife folks say that foster parenting is about 90% successful
in osprey.  Is that true in other bird species?  I know that it
is true with birds that lay their eggs in other nests, but this
bird is a stranger, albeiyoung one.  bird is a stranger, albeit a
young one.  

Does anyone else have knowledge of this trait in wild birds?  Are
willing to accept fostere like this?
