OPEN ACCESS Comparative Ecology of Black Francolin (Francolinus francolinus), Grey Francolin (Francolinus pondicerianus) and Chukar Partridge (Alectoris chukar) in Swegalai Game Reserve, Swat, Khyber Pakhtunkhwa, Pakistan Syed Fazal Baqi Kakakhel Khyber Pakhtunkhwa Wildlife Department, Pakistan *Correspondence: [email protected] Received 06-07-2020, Revised: 18-08-2020, Accepted: 19-08-2020 e- Published: 20-08-2020 Animals select resources for food, cover and nest sites. If a variety of habitats are available to an animal, it selects some and avoids others. We compared habitat preferences of three species of the order Galliformes, Black francolin, Grey francolin and Chukar partridge in Swegalai Game Reserve in district Swat Khyber Pakhtunkhwa Province of Pakistan during June 2007. We observed 75 Black francolins, 58 Grey francolins and 146 of Chukar partridges. Black francolins were observed singly or in pairs; Grey francolin in small groups and Chukar in larger groups of up to 13 birds. Six habitat types were identified in the reserve and were mapped using GIS and field surveys. Black francolin and Grey francolin were distributed in three of the of the available six habitat types: woody ravines, shrub land and agricultural fields. Chukar partridge occurred five out of six: agricultural fields, shrub lands, mountain slopes, grass lands and barren rocks. Chi-square tests showed that each species displayed significant habitat selection in relation to the availability Black francolin and Grey francolin had selected broadly similar habitats and showed highly significant preference for woody ravines. By contrast Chukar partridge preferred mountain slopes highly significantly and avoided woody ravines completely. All the three species preferred northerly aspects and foraged in the morning and evening, interpreted as a strategy to reduce heat stress in summer. We reviewed record of the Khyber Pakhtunkhwa Wildlife Department Pakistan pertaining to population of all the three species include Black francolin, Grey francolin and Chukar partridge from 2010 to 2019 and revenue generated in the last ten years from 2010-11 to 2019-2020. It was found that highest total population of Black, Grey francolin and chukar partridge was observed in 2014 with 586 followed by 2012 (570) and 2013 (545) while the population in the remaining years ranged between 188-336. A fluctuated population trend was observed during the period. The gross revenue of Rs. 663300 was generated by hunting of 1284 all the three species include Black francolin, Grey francolin and Chukar partridge through issuance of 198 permits. The community of the reserve was paid Rs. 596970 as their 90% share and the government retained Rs. 66330 as 10% share out of the total revenue generated.

Global more are not uncommon in late autumn (Roberts, population trends have not been quantified, but 1991). Sufficient amounts of utilizable resources populations appear to be stable (Del Hoyo et al. are needed to meet with animal population. 1994) so the species are not believed to approach Therefore, biologists often identify resources used the thresholds for the population decline criterion of by animals and document the availability of those the IUCN Red List (i.e., declining more than 30% in resources. The need for such documentation is ten years or three generations). For these reasons, critical in efforts to preserve endangered species the species is evaluated as Least Concern It is and manage exploited populations.

Differential resource selection is one of introduced population in United States (Birdlife the principal relationships, which permit species to International 2004). In Pakistan they occupy co-exist (Rozenzweig 1981). It is often assumed Mediterranean-type Shrubby Vegetation, that a species will select a resource that is best able grasslands, open, grassy brush lands and to satisfy its life requirements and that high-quality cultivation from semi deserts riverain valleys to resources will be selected rather than low quality openings adjacent to forested areas.

However, many factors, desert sandy clay in drier habitats to alluvial loam including population density, competition with other in river valleys to mountain forest soils in hilly species, natural selection, the chemical region (Roberts 1991).

In most areas, the habitat selection we examined the comparative populations are stable or increasing, though habitat ecology of Black francolin, Grey francolin and loss and intensive hunting may affect some local Chukar partridge in Swegalai Game Reserve in populations in their native distribution (Del Hoyo June 2007. 1994).

The Khyber Pakhtunkhwa The main method for collecting data for the Wildlife Department manages the area and hunting target species was line transects. Line transects is allowed only in the prescribed shooting season were selected randomly and duration of the survey through special permits. The study area is situated was from 06h00-20h00 each survey day. A total of in the district Swat of the Khyber Pakhtunkhwa of 12 transects were selected, varying from 2.02 to Pakistan. Geographically, Swat lies from 340-34` to 5.43 km in length and thus the whole study area 350-55` North latitudes and 720-08` to 720-50` East was covered.
