Abstract: Birds are important for the proper functioning of an ecosystem. In this study, the avifaunal diversity of the Important Bird and Biodiversity Area, Parwati Arga Bird Sanctuary situated in Gonda District, Uttar Pradesh was assessed using point count method from March 2024 to February 2025. A total of 140 bird species (53 families and 19 orders) were recorded, of which 110 species (78%) were resident, 29 species (21%) were winter visitors and one species (1%) was a summer visitor. One ‘Endangered’ species, four ‘Vulnerable’ species, and six ‘Near Threatened’ species were recorded as per the IUCN Red List. According to the global population trend, 49 species (35%) were decreasing, 39 species (27%) were stable, 26 species (19%) were increasing, and 26 species (19%) were unknown. This scientific documentation is essential for the forest department to ensure better management and conservation in the sanctuary area.

 

Keywords: Bird survey, global population trend, Gonda District, Important Bird Area, IUCN Red List status, oxbow lake, point count method, Ramsar site, residential status, wetland.

 

 

INTRODUCTION

 

Avifauna represent highly reliable bio-indicators and serve as effective model organisms for addressing a wide spectrum of environmental concerns due to their pronounced sensitivity to even subtle ecological alterations. They provide critical insights into the health status and functional productivity of ecosystems (Newton 1995; Desai & Shanbhag 2007; Li & Mundkur 2007). Within the Indian subcontinent, the extensive diversity of wetland habitats contributes to a rich avian assemblage, simultaneously functioning as significant wintering refuges for numerous migratory waterbird species. The state of Uttar Pradesh has 31 Important Bird and Biodiversity Areas (IBAs) and 25 protected areas (Rahmani et al. 2016). In the past, studies have been conducted on bird diversity in rural-urban gradients (Siddiqui et al. 2019), agricultural landscapes (Yashmita-Ulman & Singh 2021), unprotected wetlands (Yashmita-Ulman & Singh 2022), riverine systems (Varghese et al. 2007; Yashmita-Ulman 2022) and university campus (Yashmita-Ulman 2023) in Uttar Pradesh. Bird diversity of protected areas in Uttar Pradesh, such as Hastinapur Wildlife Sanctuary (Khan et al. 2013), Okhla Bird Sanctuary (Upadhyay et al. 2019), and Sandi Bird Sanctuary (Khan & Khalid 2024) have been assessed. Previous studies in Parwati Arga Bird Sanctuary have been conducted on biodiversity (Verma et al. 2023), and floristic composition (Khanna 2015; Singh et al. 2016; Singh & Srivastava 2023). But to date, the bird diversity studies are unreported, making this study a pioneering attempt in preparing an inventory of birds in Parwati Arga Bird Sanctuary.

 

 

MATERIALS AND METHODS

 

Study Area

The present investigation was undertaken at the Parwati Arga Bird Sanctuary, situated in Tarabganj Tehsil of Gonda District, Uttar Pradesh, encompassing an area of approximately 1,084.47 ha (Rahmani et al. 2016). The site was officially designated as a Bird Sanctuary on 23 May 1990. The sanctuary is characterized by extensive vegetation interspersed with oxbow lakes, namely, Parwati (a deep-water lake) and Arga (a shallow-water lake), both originating from natural depressions and forming a hoof-shaped configuration (Rahmani et al. 2011) (Figure 1).

Geomorphologically, the area represents a part of the paleochannel of the Ghaghara River, which, during its southward course, left behind several minor streams (Agarwal & Mishra 1987). These lakes maintain hydrological connectivity with the Terhi River via the Gulriha Nala. Geographically, the Parwati and Arga lakes are located between 26.955° N, 82.174° E, having an elevation of approximately 93 m. The prevailing climate can be classified as moist mid-latitude, with moderately cold winters and intensely hot summers. The region receives an average annual rainfall of about 1,240 mm, while the temperature ranges from a minimum of 4°C in winter to a maximum of 48°C in summer (Rahmani et al. 2016). Importantly, the Parwati Arga Wetland holds international conservation significance as it has been designated a Ramsar site on 2 December 2019, having fulfilled criteria 2, 3, 4, 5, and 8 under the Ramsar Convention framework (Ramsar Convention 1971; Site Management Plan 2011). The sanctuary also has been accorded IBA status in criteria A1, A4iii (Rahmani et al. 2016).

 

Method

Bird surveys were conducted monthly using the point-count method (Bibby et al. 2000) from March 2024–February 2025. On the perimeter of each wetland (Parwati and Arga), two points were fixed, making a total of four points, each of which was 250 m apart from each other (Figure 1). Each point was surveyed four times in a month, making a total of 48 replicates of each point during the one-year duration. Observations were made from 0600–1000 h during clear weather for 15 min at each point count. The species name and number of individuals of the species detected within 150 m of the observer were noted down. A Nikon 7 x 35 binocular was used to aid the sighting of species. Bird identification and residential status classification for each species were done using the standard field guide (Grimmett et al. 2011). Both the conservation status and global population trend of each bird species recorded were updated using the Red List of IUCN (2025). 

 

 

RESULTS

 

In the present study, a total of 140 species of birds belonging to 53 families and 19 orders were recorded in the Parwati Arga Bird Sanctuary (Table 1). The order Passeriformes recorded the highest number of bird species (45) (Table 1). Out of recorded bird species, resident bird species were 110 (78%), winter visitors were 29 (21%) and summer visitor was 1 (1%) (Table 1 & Figure 2). One ‘Endangered’ species (Egyptian Vulture Neophron percnopterus), four ‘Vulnerable’ species (Sarus Crane Grus antigone, Common Pochard Aythya ferina, Indian Spotted Eagle Clanga hastata, and River Tern Sterna aurantia), and six ‘Near Threatened’ species (Great Thick-knee Esacus recurvirostris, River Lapwing Vanellus duvaucelii, Black-necked Stork Ephippiorhynchus asiaticus, Lesser Adjutant Leptoptilos javanicus, Asian Woollyneck Ciconia episcopus, and Oriental Darter Anhinga melanogaster) were recorded (Table 1 & Figure 3). According to the global population trend of IUCN (2025), 49 species (35%) were decreasing, 39 species (27%) were stable, 26 species (19%) were increasing, and 26 species (19%) were unknown (Table 1 & Figure 4). Overall, 29 families recorded single species each and five families recorded two species each (Table 1).

The family Anatidae recorded the highest species richness (14 species), followed by the families Accipitridae (9 species) and Ardeidae (8 species) (Table 1). Families Anatidae and Scolopacidae comprised mostly of all winter migrants, exceptions being Knob-billed Duck Sarkidiornis melanotos, Cotton Pygmy-goose Nettapus coromandelianus, Lesser Whistling-duck Dendrocygna javanica, and Indian Spot-billed Duck Anas poecilorhyncha, which are resident (Table 1). Families Ardeidae, Strigidae, Columbidae, Cisticolidae, and Sturnidae comprised of all resident birds. The Blue-tailed Bee-eater Merops philippinus was the only summer visitor (Table 1).  

 

 

DISCUSSION

 

The current study records 140 species of birds, which is higher than the number of species recorded in other bird sanctuaries of Uttar Pradesh, e.g., Hastinapur Wildlife Sanctuary (117 species) (Khan et al. 2013), but lesser than the species recorded at Okhla Bird Sanctuary (302 species) (Upadhyay et al. 2019). Other studies from different bird sanctuaries in Tamil Nadu such as Therthangal (96) (Byju et al. 2024), Chitrankudi (122), Melsevanoor-Kelselvanoor (117), Sakkarakottai (116) (Byju et al. 2025) and Pakhibitan Bird and Wildlife Sanctuary, West Bengal (124) (Roy et al. 2024) reported lower bird species than the current study, whereas Manjeera Wildlife Sanctuary, Andhra Pradesh (164) (Prasad et al. 2014) and Samanatham Bird Sanctuary, Tamil Nadu (150) (Byju et al. 2023) reported higher bird species than the current study. The number of winter migrants (n = 29) recorded in this study is higher than that recorded in Hastinapur Wildlife Sanctuary, Uttar Pradesh (19 species; Joshi et al. 2021) and lower than that recorded in Okhla Bird Sanctuary, Uttar Pradesh (40 species; Mazumdar 2019). The current study recorded 11 threatened bird species, which is similar to the results obtained in Hastinapur Wildlife Sanctuary, Uttar Pradesh (11 species; Joshi et al. 2021) and higher than the species recorded in Bhimbandh Wildlife Sanctuary, Bihar (five species; Khan & Pant 2017) and Okhla Bird Sanctuary, Uttar Pradesh (10 species; Mazumdar 2019).

Parwati Arga Bird Sanctuary hosts diverse flora and fauna, including many resident, rare, and migratory species due to its diverse habitats consisting of two oxbow lakes having freshwater ecosystems, along with marshes, swamps, interspersed with agricultural fields and adjoining Tikri Reserve Forest (Image 1). These habitats support the foraging, nesting, and roosting activities of waterbirds and terrestrial birds (Hattori & Mae 2001). The availability of fish in lakes, grains, and insects in the adjacent agricultural fields & grasslands provides good foraging ground for the birds (Prasad et al. 2014; Anand et al. 2023), whereas the aquatic vegetation and adjoining forests provide shelter, escape routes, cover, and nesting sites, attracting diverse birds (Yashmita-Ulman & Singh 2022). The shallow water bodies with variable depths (Colwell & Taft 2000) might also be a factor attracting birds in the Sanctuary. In the current study, the family Anatidae recorded the highest species richness. This is similar to the findings of Kumar & Gupta (2013) in Chhilchhila Wildlife Sanctuary, Haryana and Prasad et al. (2014) in Manjeera Wildlife Sanctuary, Andhra Pradesh. Families Anatidae and Scolopacidae comprised most of the winter migratory birds, and only one summer visitor was found, which is similar to the results obtained by Prasad et al. (2014) in Manjeera Wildlife Sanctuary, Andhra Pradesh.    

The study results highlight the importance of the Sanctuary for the resident and migratory birds. Therefore, long-term monitoring of birds and threat assessment is required to assess the impact of the changing environment and surrounding landscapes on the birds of the Sanctuary. This scientific database is a prerequisite for scientific management and conservation of the sanctuary by the forest department.
