To find out the Indian Peafowls abundance its distribution in the Meghmalai forest was carried out during the period of 2013 to 2014. The distribution of Indian Peafowl was obtained in all the habitats in the study area with the wide range of altitude (330-950m). The sightings of Indian Peafowls were recorded in all the eighteen transects as well as four different seasons in Meghamalai forests. This study area consisting of five different habitats namely southern dry deciduous scrub forest (SDSF), southern dry mixed deciduous forest(SDMDF), southern moist mixed deciduous forest (SMMDF), southern subtropical hill forest (SSTHF) and miscellaneous and plantation forests (MISC+PL). The Indian Peafowl densities in the study area, ranged widely from 9.06/km 2 (95% CI=6.56-15.17). The highest density was recorded in the Summer season 10.13/km 2 (95% CI=14.98-43.38) and the lowest density was obtained in the Post-monsoon season 9.06/km 2 . The maximum density of Indian Peafowl was recorded in SDSF habitat 18.32/km 2 (95% CI=11.23-21.32).

Introduction:-
The Indian Peafowl is regarded as protected species through the Indian Wildlife Protection Act (1972) and listed as least concern (LC) by the International Union for Conservation of Nature (IUCN). According to Bird Life International [1] Pavocristatus is a threatened species. Even though there are several threats against this species and for their survival in many parts of the fragmented areas in the country. The Indian Peafowl is native to south Asia, but introduced and semi feral in many other parts of the world. The Indian Peafowl is under the inclusion of Order Galliformes, Family Phasianidae, Genus Pavo and the species is cristatus. [2] Many workers draws particular attention to the need of quantitative accurate and comprehensive maps of species distribution and abundance. Without such a database in many fragmented areas it will not be possible to plan priorities in conservation. Hence this species is highly emphasized and it is essential to take up an in depth research on the population and habitats in the fragmented areas in the southern parts of India. Keeping in view, the aforesaid facts, that term study on Indian Peafowl at the Meghamalai forests, Tamil Nadu, Western Ghats was studied. The present study is focused mainly on the population in different seasons during the period of 2013 to 2014 in the Meghmalai forests, Western Ghats south India.

Int. J. Adv. Res. 5 (8), 789-794 790 The Indian subcontinent is home for wide range of flora and fauna owing its to varied range climatic, topographic and vegetation structure. The present survey is not only served as first step to determine the distribution and abundance of a species but also it helped in understanding its habitat requirements. Miller [3] highlighted the importance of distribution and abundance of species in assessing the status. Knowledge of the number in a population is a prerequisite for effective wildlife resource management.
Conroy and Noon [4] opined that in gaining a useful understanding of the conservation status of a particular species, the biologists must have information on the distribution of the species, and occupancy of available and relative population estimates. It is reported that estimates or measures of a population are useful making comparisons of related species of populations of the same species in different habitats or of the same population at different times. The selection might thus be expected to exert rather strong influences on habitat selection patterns (Lack [5]; Ramesh and McGowan, [6] andOdum, [7]). No detailed information is available on abundance and distribution of Indian Peafowl. The current study has not only served as a first step to determine the distribution and abundance of a species by also it helped in understanding its habitat requirements. The objectives the study wasto document the distribution of Indian Peafowl and its abundance in different seasons in the Meghamalai Forests, Western Ghats.

Results and Discussion:-
The distribution of Indian Peafowl was obtained in all the habitats in the study area with the wide range of altitude (330-950m). The sightings of Indian Peafowls were recorded in all the twenty transects as well as four different seasons (Table: 1) in Meghamalai forests. This study area consisting of the habitats (Table:2) namely southern dry deciduous scrub forest (SDSF), southern dry mixed deciduous forest(SDMDF), southern moist mixed deciduous forest (SMMDF), southern sub-tropical hill forest (SSTHF) and miscellaneous and plantation forests (MISC+PL).

Density of Indian Peafowl in different Seasons:-
The Indian Peafowl densities in the study area, ranged widely from 9.06/km 2 (95% CI=6.56-15.17). The highest density was recorded in the Summer season 10.13/km 2 (95% CI=14.98-43.38) and the lowest density was obtained in the Post-monsoon season 9.06/km 2 (Table:1& Fig. 1 The present study revealed the distribution of Indian Peafowls in all the seasons and in four different habitats except in SSTHF (rare abundance) and the wide range of altitude 330 to 750 m in the Meghamalai forest areas. This study also revealed that the populations of Indian Peafowls were found in the particular transects containing habitats mostly in the open areas of forests in the study area.
Sathyanarayana and Veeramani [10] reported at Tamilnadu, the abundance of Indian Peafowls in scrub jungle may be due to the availability of sufficient food plants, insects, roosting tress and good ground cover for breeding and protection. According to Subramanian et al [11] the Grey jungle fowl prefers mostly scrub jungle when compared to southern sub-tropical hill forests and further stressed that the ground litters and fruiting plants plays significant role for Grey junglefowl (Subramanian et al [12]; and Subramanian et al [13]). Veeramani [14],Johnsingh and Murali [15] stated that more abundance of Indian Peafowls were recorded in scrub jungle in Mudumalai Wildlife sanctuary. The rare sightings of Indian Peafowl in SSTHF in the study area may be a high altitude and sparse availability of shrubs and bushes. The present study on abundance and distribution revealed that Indian Peafowl densities in the study area were highest in the summer season and similarly the maximum densities were noticed in the Deciduous habitats when compared to higher altitudinal habitats such hill forest. It seems to be an ideal microhabitat variables as well as clearings in the summer and it may be the preference of open areas. Ahmed and Musavi [16] have observed 65% white-crested Kalij pheasants in the scrub jungle when compared to other habitats Ranikhet, Kumaun, in the Himalayas. Silva et al [17] stated that the thorn scrub vegetation in Ruhuna National Park is ideal for the Ceylon Junglefowl especially in the dry season. According to Gaston ([18]; Easa [19]), the line transect method is the simplest method to get an index of pheasant population and can be carried out at any time of year. Hence this method is most suitable to estimate the abundance of pheasants. Easa [19] reported the reappearance Indian peafowl in Parambikulam area in Kerala.   The more abundance of Indian Peafowls in scrub jungle may be due to the availability of sufficient food plants, insects, roosting tress and good ground cover for breeding and protection purposes. Peafowl prefers mostly scrub jungle when compared to southern sub-tropical hill forests and may be the reason for the ground litters and fruiting plants plays significant role The rare sightings of Indian Peafowl in SSTHF in the study area may be a high altitude and sparse availability of shrubs and bushes. The present study on abundance and distribution revealed that Indian Peafowl densities in the study area were highest in the summer season and similarly the maximum densities were noticed in the Deciduous habitats when compared to higher altitudinal habitats such hill forest. It seems to be an ideal microhabitat variables as well as clearings in the summer and it may be the preference of open areas.
