FOOTNOTES:
[30] Not including dental abnormalities, which are described in table
5.
The following organs were excised from wolf-killed deer and examined
grossly in the field for parasites and abnormalities (fig. 12): lungs
(six animals, normal); heart (seven animals, normal); liver (four
animals, one small unidentified tapeworm cyst). Twin fetuses were found
in each of two adult does examined.
Twelve deer were checked for body fat in one or all of the following
areas: back (subcutaneous), kidneys, heart, omenta. Of these animals,
seven had large amounts of fat, but five were almost depleted of fat
from these stores. These five were all killed in February or March
1969; three were fawns, and two were yearlings that had not yet shed
their deciduous premolars.
Of 69 animals examined for femur marrow condition, two had fat-depleted
marrow. One was a fawn killed in March 1969 that had not shed its
deciduous first incisors, and the other was a 5-1/2-year-old buck
killed in February 1966.
A fawn and a yearling that had died in February 1969 from unknown
causes also had fat-depleted, marrow. These animals might have been
killed by wolves, for wolves had fed on them. However, they could have
died from malnutrition and been eaten as carrion.
