Home Point Study of Birds and Mammals Diversity Allied to Humans in Lockdown of COVID-19 at Bharatpur, Chitwan, Nepal

Abstract

The birds and mammals are nature gifted gene banks which differ greatly with variation in altitudes, climates, landscapes, vegetation and availability of food and water. The altitudinal variation in Nepal is 60 m to 8,848 m which affects climatic conditions and habitat types within short distance that influence species diversity of wild animals. Therefore, the objectives of this study were to reveal species richness, behaviors and luring factors for birds and mammals to attract to an urban area of Bharatpur Metropolitan City, the South-central lowland of Nepal. The methods applied to record species diversity of birds and mammals were made from a home point (a point of study made at the Northwest corner of verandah in first floor of my home) located in Bharatpur-9, Saradpur, Sitalpath, in the coordinates of 27˚39'55"N and 84˚26'08"E. The animal species were observed thrice daily (at 7 AM, 10 AM and 2 PM) for 2 months beginning from 24 March to 23 May 2020 during the period of lockdown of COVID-19 and were listed in "Observation Data Sheet". The photographs and/or videos were taken except one of the species of bats (i.e. Myotis formosus) and six species of birds which were flying swiftly over the sky in 70 m in diameter (i.e. 7,436 square meters or 22 kattha in area) of the home point. The results obtained from my study were; 83 species, 53 genera and 37 families of wild birds; and 6 species, 5 genera and 3 families of wild mammals. Among birds, Dicrurus and Ploceus were recorded the highest 7.54% (4/53); followed by Acridotheres, Megalaima, Merops, Oriolus, Psittacula and Streptopelia with 5.66% (3/53), and remaining twelve genera were found 3.77% (2/53), and thirty three genera were 1.88% (1/53). Similarly, 33.33% (2/6) of Herpestes; and 16.66% (1/6) of each Canis, Vulpes, Pipistrellus and Myotis were recorded among mammals. Conclusively, I found that the species of birds and mammals were lured to human settlement area due to availability of food (i.e. small in/vertebrates, kitchen garbage etc.

New Record of Civets at Bharatpur, Chitwan and a Review of the Species Diversity in Nepal

“…Among the sporadic research reports published by [27] [28] [30] remain imprecise in context to Nepal regarding typical recordings and reporting of particular location, date and time. The study of civet behaviors, associated threats and population status is still in the base line although the sympatric association of wild mammals and the people was reported by [34] Chitwan due to availability of fruit bearing plants and organic kitchen garbage.…”

“…The animals were careless from the risk at day time, especially babies. The restless behaviors at dawn and dusk lead to tragic cases like electric shocks, vehicle accidents, and were killed by people while making noise on/under the tin roofs and trying to dine poultry and injure pets as well (Figure 2) [34].…”

Impact of COVID-19 lockdowns on house sparrows: Comparative study from an Indian context

“…[ 4 ] studied the impact of urbanization on house sparrow distribution, particularly in the city of Kolkata, India. A few other related articles which one may refer to are by [ 5 ], where the authors surveyed the house sparrow decline in West Bengal, [ 6 ], who analysed the effect of COVID-19 lockdowns on the diversity of bird and mammals in Nepal, or [ 7 ], where they studied the effect of urbanization on the bird diversity in Kerala, India.…”
