Rapid Avian Survey of Upstream of Ravi River, Chamba, India

River Ravi

Virat Jolli: Chamba town is in Chamba district of Himachal Pradesh. It is located on the bank of Ravi River. This river is one of the majour river and tributary of Indus River System. Government of India has constructed Chamera Hydro Electric Project (CHEP) on the upstream of Ravi River to generate electricity. Chamera Hydro Power Project comprised of three stages: Stage-I downstream of Chamba town generating a total of 540 MW; Stage-II upstream of Chamba town generating 300 MW while Stage-III further up of Stage-II generating a total of 231 MW of electricity. The silent feature of these projects is that these are run of the river scheme which require relatively lesser impoundment of river water for electricity generation.
Considering their low impact on environment, we made a rapid field assessment of birds along upstream of Ravi River from Chamba town to Bharmour which covered two CHEP-II & III to know the avifauna of the Ravi River. 
It was 6th of June 2018 i.e. Summer season, I along with Dabe Ram hired a taxi to cover 60 km distance from Chamba Town to Bharmour. We left the town during morning at around 7:15 am and begin the rapid bird assessment from 7:30 am starting from a Karian Station. The station is located on the outskirt of Chamba Town. We spent 10 minutes at this point and spotted birds like Striated Prinia, Himalayan Bulbul, Russet Sparrow, Ashy Drongo and a Shikra but to our surprise no river birds were seen. We left the station and travel 3 km ahead and observed birds for another 10 mins. At this point we saw some Blue Whistling Thrushes, White throated Kingfisher some more Ashy Drongos, Alpine Swifts and Purple Sunbird

Blue Whistling Thrush

Hoping to find more new bird species we moved ahead and stopped at Mehla Station, at this point we spotted only Blue Whistling Thrush and a Striated Prinia. After this point we halted at another important station Rakh. This station had flock of Blue Rock Pigeon, few Blue Whistling Thrushes and pair of Black-eared Kite.

Our next station was Dunali where only one Blue Whistling Thrush was seen we left the site and move further North and reached our last station Durgati close to Chamera HEP-III  here we saw Black eared Kite, Blue Rock Pigeon and Blue Whistling Thrush.

When we began our rapid bird assessment, we were expecting to see DippersRedstarts, Wagtails, Kingfishers but spotted none. The current rapid assessment pointed out fact that Hydro Power Projects are reducing the avian fauna probably by affecting their food supply and nesting sites. The river flow through some important protected areas like Tunda Wildlife Sanctuary and Kugti Wildlife Sanctuary and therefore has high conservation value. Though, we need more extensive survey to validate it further however our rapid assessment has shown the likely negative impact of HEP which we have published earlier (Jolli V 2017).

Revisiting Wetlands of Hoshiarpur, Punjab

Revisiting Wetlands of Hoshiarpur, Punjab#Wetlands #Birds #Ecosystem #LanduseVirat Jolli: Last year in the month of November, 2017, we visited a specialised wetland ecosystem in North Eastern part of Punjab in Hoshiarpur District. These wetlands are locally known as chos (seasonal nallahs). During our past visit, we documented some important rare and large sized waterbirds in these wetlands and surrounding areas along with other terrestrial birds and animals. This has fascinated us and raised our curiosity to further explore the region and know more about this relatively little and unexplored region.

Keeping this in mind, this year in the month of October, 2018, we planned to revisit the site and document its biological wealth. It was a sunny day, I along with a local villager named Gurpreet  explored chos of this region. These chos received water from Himalayan rivulets which recharge them and flooded them during monsoon season. Gurpreet, told me that this year the whole region got su…

Taj Mahal: Through The Eyes of Ornithologist

Taj Mahal: Through The Eyes of Ornithologist
Virat Jolli: Taj Mahal a wonder on earth is India’s finest monument. Considering its historical, cultural and unique architectural design, UNESCO has enlisted it as a World Heritage Site in 1983. It was built by 5th Mughal Emperor Shah Jahan in the year 1632 A.D in memory of his beloved wife Mumtaz Mahal. This monument is built on the banks of River Yamuna. The monument is a marbled mausoleum and has well managed gardens planted with variety of fruit bearing and medicinal trees. Taj Mahal is known for its unique Mughal architecture but current article aims to highlight much less talked about natural aspect i.e. birdlife.

The Yamuna River, a majour tributary of River Ganga originates from Himalayas descend down at Poanta Sahib, Himachal Pradesh and enters plains of Northern India. This is one of the most important River of India as 70% of water requirement of Delhi NCT is fulfilled by it. River Yamuna falls within the flyway zone of birds tha…


Virat Jolli: Bundi is situated on South East of Rajasthan.  It is 471 km from Delhi and 35 km from Kota. It is easily accessible via train and road network.It is surrounded on three sides by Aravalli Hills and it has some number of water bodies which is a lifeline for whole region. These water bodies includes small dams, lakes and ponds. These water bodies not only provide water in the region for agriculture and drinking purpose but they also being used by many birds including migratory one as stop over and nesting sites. Its not surprising that the Bundi is known to harbour variety of birds. This has prompted us to visit Bundi and explore the birds of the region.
Our team visited Bundi, during winter season i.e in the end of December 2017. We spent a total 4 days with a total of 10 hrs spent in bird watching and recorded a total of 51 bird species. I am presenting a short travelogue of my visit.
Day 1On day one we visited Civil lines and Raniji Ki Baori both these places are in Bundi t…
