Subject:
Puerto
Rican
Plain
Pigeon
and
Disulfoton
In
our
files
and
databases,
the
Puerto
Rican
Plain
Pigeon
is
indicated
to
occur
in
several
municipalities
in
Puerto
Rico
where
coffee
is
grown.
The
municipality
of
Utuado
had
thousands
of
acres
of
coffee.
When
we
initially
contacted
the
Fish
and
Wildlife
Service
in
Puerto
Rico,
it
was
indicated
to
us
that
the
pigeon
did
occur
in
Utuado
and
several
other
municipalities
where
smaller
amounts
of
coffee
are
grown.
However,
in
an
April
18,
2002
phone
conversation
with
Marelisa
Rivera,
endangered
species
specialist
with
the
Puerto
Rico
office
of
the
Fish
and
Wildlife
Service,
we
were
informed
that
our
information
was
old.
The
pigeon
no
longer
occurs
in
coffee
growing
areas.
With
no
exposure,
there
will
be
no
effect.
Therefore,
there
is
no
need
to
provide
special
protection
for
this
species
from
disulfoton.

According
to
Ms.
Rivera,
the
Puerto
Rican
sharp­
shinned
hawk,
Puerto
Rican
broad­
winged
hawk,
and
the
Puerto
Rican
boa
are
the
only
listed
animals
that
occur
in
coffee.
These
three
species
all
feed
on
bats,
mice,
and
birds.
Since
there
are
data
indicating
a
lack
of
secondary
hazards
for
disulfoton,
there
will
be
no
effect
on
these
species
from
disulfoton.
