|If you ask most young children in spring to name a
rabbit that they might see in their back yards, the answer would
probably be, " umm… the Easter Bunny?" Ask any wildlife
rehabilitator to name a rabbit that they see around Easter and they
would probably roll their eyes, grin, and answer, " Cottontail
rabbits". People often ask, "what is the most common species
that wildlife rehabilitators get calls about?" Again the answer
would be, "Cottontail rabbits".
I recall one call that I
received from a woman concerned about a rabbit digging a hole in her
yard. She had asked me if rabbits laid eggs. I couldn’t resist a joke
so I answered, "Only the Easter Bunny ma’am!" Then I
explained the facts of rabbit life to her. Most new wildlife
rehabilitators learn the ropes of rehabbing by working with rabbits, due
to the frequency of rabbit calls. Cottontail babies are frequently
caught by cats and dogs, cut by lawn mowers and weed whackers, and
displaced by the spring time activities of humans. We begin gardening,
remove swimming pool covers, or clean up our back yards in preparation
for summer, and we accidentally uncover a nest of baby bunnies. It is
not uncommon for rehabbers to get at least one or two rabbit calls on a
daily basis, from spring to late summer. We all know that rabbits are
prolific breeders. Natures’ way of ensuring the survival of a species
that is near the bottom of the food chain is to make sure they have many
Cottontail Rabbit (Sylvilagus floridanus) is one of the most common
rabbits in our area. They should not be confused with hares. Rabbits run
- hares hop, or so I have been told! Baby rabbits are born altricial,
meaning that they are dependent on their mother after birth. At birth,
they are born with their eyes and ears closed, without fur, and unable
to walk around. Baby hares are born precocial, meaning that they are
born with their eyes open, they are able to hop around, and already have
fur at birth. I have also heard people refer to rabbits as rodents.
Rabbits are not in the rodent family, they are Lagomorphs.
considered crepuscular, which means that they are most active around
dawn or dusk. When not active, cottontails rest in a depression in the
ground called a form. Only during severe storms, will a cottontail seek
out an old woodchuck hole or rock crevice to hide in. A cottontail’s
average home range is between three to six acres, but they can extend to
about 15 acres. Rabbits generally use the same trails every day. All of
life’s needs are found along their daily trails. Even when running
from danger a Cottontail rabbit will usually stay on it’s trail, which
generally loops around in a wide circle. Cottontails eat such a wide
variety of vegetation and fruit that to mention dietary specifics would
be beyond the scope of this profile. Winter diet changes to woody
plants, soft bark, and small twigs when the usual grasses are
unavailable. Like many herbivores, Cottontails practice coprophagy,
which means that they eat some of their feces right from their anus.
This is necessary to re-ingest undigested plant matter to obtain
nutrients that would have been passed out and lost.
In our area of Western
New York, Cottontails begin breeding around February and continue until
late September. During courtship the buck and doe go through an odd
ritual where the buck will try to gain acceptance and mating position.
He will either urinate on her, or she will urinate on him, and they will
then groom prior to mating. Gestation is about 28 days long. The doe
will prepare a nest near the base of a tree, root, rock, or along the
edge of a wall or other man made object, where the soil suits her. She
will dig a hole about four inches deep and up to eight inches long. She
will line the hole with bits of dried grass and fur that she pulls from
her body. The mother rabbit will give birth to as many as three to nine
young, with an average of four. The doe will then cover the nest with
dry grasses, and leave the area. The babies will remain in the nest,
while the doe purposely stays away to keep the location of the nest a
secret from predators. Mom will only return to feed the young at night.
She will squat over the hole while the babies instinctively reach up to
nurse. At only a few days of age the eyes and ears open. At 10 days of
age the young begin to sample the grass just outside the den entrance.
At three to four weeks of
age the young are weaned, and the small white spot of fur on their
forehead usually begins to disappear. By the 4th and 5th
week they are on their own, and their mother does not return. At this
stage they are about six inches long and their only defense is to sit
absolutely still in hopes to avoid discovery by a predator. When danger
gets too close, they will try to run to the safety of cover. As soon as
the doe has covered her new young in one nest, she will immediately mate
Why is the Easter Bunny a
symbol of Spring? For ancient peoples, the natural fertility of the
rabbit seemed to signify the fertility and prosperity that is promised
as trees begin to bud and crops are planted. We hunt for Easter eggs so
we can share in nature’s abundance. As you begin to get your homes and
gardens ready for warmer weather, look for nature’s sign of abundance,
and be aware of the needs of the rabbits who may share your land.
Rabbit rehab tip #1.
If you discover a bunny nest, do not assume the young are abandoned.
Cover the nest back up with the dry grass, mark the top of the nest with
two thin twigs in an "X" pattern, and leave the area. Check
back the next day. If the X is moved, the mother is returning to feed
them. If the X is intact, uncover the young and feel them to see if they
are warm. If they are cold and limp, then they need to be rescued.

a baby bunny".
Rabbit rehab tip # 2. Always
support the back legs of an adult Cottontail when handling it. Their
skeletal system is only four percent of their body weight and violent
kicking can break their spine. Never hold them by their ears, and never
hold them by the scruff of their neck. Rabbit skin is very thin and will
pull loose from their subcutaneous tissue easily, causing what is known
as a degloving injury.
