Yes, Fernando, I am talking about the same Socorro Dove project which was
started by Juan Martinez and Luis Baptista.
According Juan, the military service on Socorro Island is very cooperative =
to
support the project and helps to eliminate feral cats from the island. In
January of this year, they had a meeting to plan the construction of breedi=
ng
aviaries on Socorro island. Thus, it looks like that re-introduction could =
be
started within the next years.
Juan is concerned about the genetic purity of those SDs kept in the USA. Wi=
th
mean of genetic analyses he found many birds which were descendants of
Socorro/Mourning dove hybrids. Thus, he is especially counting on doves fro=
m
Europe.
We at Birdpark Marlow participate in the European Breeding program of the S=
D. We
keep nine breeding pairs and want to check them for genetic purity. We make=
a
combined approach by integrating genetic, morphological and bioacoustical
studies.
Genetic analyses should be most reliable. However, since nobody (to my
knowledge) has processed SD blood before it became extinct, how should one =
know
how a pure SD looks like genetically? Thus, one has to be cautious with the
interpretation of genetic data and base the comparison on more than one
parameter.
We have a master's student who has just started with the recordings of our =
SDs.
Any donations of sound recordings of the Mourning Dove (Zenaida macroura) f=
or
reasons of comparison would be most appreciated. You can be assured that th=
ey
are only used for conservational purposes.
Best thanks
Martin
