| Bushy-Tailed Jirds |

Introduction
Sekeetamys
calurus
do not share their genus with any other species, and show many
phenotypical differences to the true jirds of the Meriones genus.
They are no bigger than a full size Mongolian gerbil. I think they have
a pear shape about them, from the pointy nose tapering out to their
proportionately broad rear. Its body is finished with, as its name
suggests, a bushy tail, which is usually just as long as the body. They
have a golden dark orange coat on top and as is characteristic with most
if not all natural colour gerbils and jirds, it has white under parts.
There is black ticking covering the topcoat and the tail is covered with
dark hairs, the tails of dominant males appears bushier than the
sub-ordinates. Naturally
inhabiting rocky, dry areas of Egypt and Arabia, they were discovered in
the 1950's. They
are becoming relatively common in the UK, as I have seen them advertised
in two shops, although no specimens were present. I guess this shows
they were not uncommon enough not to be snapped up as soon as they were
displayed. My
oldest individual is around two years old and doing well, I know of an
individual that is still doing well bordering on five years of age. I
know of no other used names for this species except the Bushy-tailed
gerbil, informally known as 'Bushies'. Feeding
Bushy-tailed
jirds require a diet that is higher in protien than most other
gerbils/jirds, it can be given in the form of live food, dry cat food or
chicken, and also rat food is usually higher in protein. Although rat
food does have a higher protein level, it is usually accompanied by
excess dry biscuit content, which is not favoured by the Bushy tails. They appreciate all
fruit and vegetables but as usual citrus fruit and lettuce should be
kept to a minimum. They will 'hunt' for
and prey on any live food given and all it will be eaten quickly.
Cuttlefish and/or limestone blocks are needed and relished. Housing These species seems
to be adept at climbing and therefore I usually keep mine in terrariums
with a cage extension allowing long and complex branches to be used. I
often set a few shelves resting on the glass supports - found on most
tanks - to make more tiers. The horizontal wire bars of the cage annex
allow climbing as well. A nest box seems a
necessity and wood ones are not chewed, which is a bonus. I have used a
plant pot and a finch box. Not being too bothered with burrowing only a
shallow litter is required topped hay is ideal. I find bedding is
rarely used but tubes - cardboard or otherwise - are liked. Behaviour They
are very active from late evening to early morning and prefer the cover
of darkness before they emerge.
Little aggression is
ever observed, though individuals often appear with nipped tails, this
is more likely with a low protein diet. BT jirds should never
be kept alone, keep them in pairs, trios or colonies depending on your
needs and space. I have never had any problems introducing adult
individuals and my source of these animals has had no problems inserting
an adult male into an establish colony. Breeding Mating is quite often
obvious and is usually initiates around late evening. The male will
chase the female for many hours. The litter of about 3-5 is born after a
gestation of 21-23 days. The first litter is usually no smaller than any
other.
Some litters are
eaten, but if enough calcium and protein are given this should not be a
problem. If you suspect a litter has been born try not to disturb them
for a few days to increase the chances of survival. Weaning occurs at
4-5 weeks.
There
are apparently two strains of bushies, one that breeds well in a colony
and one that does not. I guess one will just have to experiment with
their animals, or just be save and breed in pairs. |
