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.

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 Dippers,  Redstarts, 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).

EARTH DAY: 22 APRIL

Earth Day Special Virat Jolli: Earth Day is celebrated around the world for the protection and  preservation of Earth. It was Gaylord Nelson a US senator from Wisconsin who first gave the idea for commemorating Earth Day. Since 1970, Earth Day is being celebrated on 22nd April. From 1990s onward around 192 countries celebrate this day. According to Earth Day Network, this year’s Earth Day is dedicated to spreading awareness about the pollution caused by plastic and the need to eventually end its use.                                                        "END PLASTIC POLLUTION" The theme is quite relevant considering the impact of plastic pollution on our earth ecosystem. Plastic is a hydrocarbon polymer and is non biodegradable which make it persistent in our environment.  Our own Delhi which is considered as heart of In...

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 5 th 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. Taj Mahal  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 fall...

Revisiting Wetlands of Hoshiarpur, Punjab

Revisiting Wetlands of Hoshiarpur, Punjab #Wetlands #Birds #Ecosystem #Landuse Virat 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. Chos of Punjab 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...
