Here we present an observation on
the rutting behaviour of the nationally threatened
population of Red Deer in Kashmir, Cervus elaphus hanglu, commonly
known as Hangul, in the Dachigam National Park (DNP).
Study
Area
Dachigam National Park,
(34005’-34012’N & 74054’-75009’E)
is situated 21km northeast of Srinagar (Fig. 1). Roughly rectangular, the park
has a total area of 141km2. It is approximately 24km in length and 6km in breadth ranging in
altitude from 1700m to 4000m. It
comprises of a more or less contiguous range of mountains, except in the west
where it has been artificially fenced along the borders of the national park.
The average climate of Dachigam is sub-mediterranean. Marked by the beginning of fir forest, the
park is generally divided into the lower (26km2) and upper Dachigam, (115km2).
Methods
Observations of hangul deer were made along eight transects (I-VIII) having
a total length of 24.5km in lower Dachigam. In addition, the lower Dachigamslopes were scanned from specific vantage points and watch towers using 10x50
field binoculars. The slopes facing the
north and the south were scanned alternately. Observations were recorded for brief periods only when the animals were
visible on open slopes, without disruption due to dense canopy. Field data pertaining to behaviour,
herd size and composition were collected on data sheets and classified into
three groups: stags, hinds and fawns. The anthropogenic activities in the rutting grounds were also recorded.
Results
and Discussion
The rutting or reproductive
activity began by late September and extended up to the first week of November.
The mature stags, which may be found in small groups in summer, became
intolerant of each other and separated. The rut took place in the main valley and along the slopes of lower Dachigam (Fig.1). The peak of the rut was from October 9 to 20 after which it faded
out. This observation is similar to that
of Kurt (1977) and Schaller (1969), who reported peak of rut in the second week
of October.
The most conspicuous feature of
rut was the reverberating resonant roaring calls by stags. During this the stag raises its muzzle
slightly upward, and with partially open mouth emits the sound at high
intensity. The roar is a loud resonant
bugle beginning harshly and ending on a clear deep note dropping progressively
in pitch.
An estimated 8-11 stags were
present in rutting grounds. The stags were either solitary or had at the most 4
hinds with them. Out of 34 to 47 hangul observed, 8-11 were stags, 21-30 were hinds and 4-6
were fawns. A total of 24 breeding herds were seen, the size of which varied
from 2-5 and included one large stag, one or more hinds, and occasionally they
were with a fawn. On several occasions
there were one or two young stags in the herd. The largest number of hinds seen with a stag was four. Solitary hinds were seen on seven occasions.
The roar by a stag often resulted
in response to roars from one or more stags and then there is an exchange of
roars back and forth. This roaring
continued at times for about 40-43 minutes. The stags roared more frequently and spent more time standing at such
times of the day when the hinds were feeding. Stags with hinds roared more and tended to spend less time feeding on
days when the nearest rutting stag was close by.
The calls were mostly heard in
the study area between the dawn shortly after 0600hr and the dusk till 1830hr,
which is in accordance with Kurt (1977) and Schaller (1969). Roaring reached
daily peaks between 0700 and 0900hr, and again between 1640 and 1830hr, but did
continue even after. Counting of calls was discontinued after 1900hr (Fig.
2). Only large stags with more than
eight points were observed to roar. These mature stags had dark-brown swollen necks in contrast to the
grey-brown slender necks of the young stags. From September 23 onwards the calls were heard only occasionally. The frequency of the calls varied
considerably from day to day and appeared to be related to the weather
condition. On warm and clear mornings
stags were heard roaring less often than on rainy cool mornings. Higher numbers of calls were heard on cloudy
days than on clear days.
After 20 October, the number and
intensity of the roars decreased considerably indicating that the peak of rut
had passed. Occasional roars were heard
up to 09 November. It was also found to
be related to topographic aspects. Roaring started earlier on the south facing slopes where the sun shines
earlier than the north facing slopes. The roaring intensity was found to be directly related to the density of
the stags in a particular area. A call
by one stag frequently stimulated one or more stags to respond, sometimes for
about 40-45 minutes. Since roaring tended to occur more or less at the same
time intervals, it could be considered an attempt to acoustic territorial
demarcation. When a rutting male was
approached by a number of young males at the same time, he always chased away
the oldest or the best developed stag first. The chase-away strategy adopted by a mature stag is to steadily walk towards
the rival stag that may be young or is seen with hinds.
Stags in rut were seen to trash
their antlers frequently against bushes and trees. This activity was seen to continue at a
stretch for 5-10 minutes. Sometimes,
this behavior was more pronounced when another stag was in the close
vicinity. Many small plants were thus
damaged by such stags. Marks of fraying
and trashing were generally easily found and represented by bark stripped more
or less completely around the vertical stems of woody plants. Occasionally signs were also found on grass
and soil. Prunus sp., Rosa sp., Berberis lycium, Indigofera haterantha andCotoneaster sp. were the most common species used for antler-trashing in
the broad leaved forest and the grass covered slopes. Marks of fraying were
observed from 32.5 up to 180cm above the ground level, with the average ranging
from 30 to 90cm. On Prunus sp., fraying marks were seen from a height of 60cm up to 173cm. For Berberisit was from 33cm onwards and for Rosa sp. it ranged from 50cm up to
145cm. According to Kurt (1977) antler
trashing was a means of communication to warn other males.
Courtship behavior was observed
on six occasions and got disturbed on a couple of occasions due to vehicular noise
from the 6km road to VIP lodge at Draphama in lower Dachigam. The stags stayed close to the hinds. When the hind walked, the stag followed. When the hind browsed, the stag stopped and
remained standing erect behind or parallel to the hind. On 11 October 2006, a stag and a hind were
observed from 0810hr till 1825hr. They
remained together all the day resting most of the time. The stag made a number of attempts to mount,
but was not successful. At 1741hr the stag
went round the female, placed his chin on her rump and then mounted. The stag mounted twice in quick succession.
The first one was of the longest duration, of about 6 seconds followed by the
2nd, which was of 3 seconds duration. The number of calls that this stag gave throughout this observation
period was 43. Only mature stags (8
tined and above) were observed to be involved in courtship.
Overall rutting was disturbed by
daily convoys across the hangul habitat, and other
interferences like livestock grazing, grass and fuel extraction by locals. Gruisen (1983),
Shah et al. (2008) and Bhat (2008) recorded several
anthropogenic disturbances impairing the normal behaviourof wild animals including hangul in DNP. Kurt (1977) has reported the clear cut
difference in the behaviour of rutting stags in
disturbed and undisturbed areas.
Recommendation
Restriction of vehicular traffic,
to lower Dachigam during rutting season of hangul should be enforced and fully implemented.
