Kerala bird survey traces Salim Ali's trail

Thiruvananthapuram, May 28: When renowned ornithologist Salim Ali conducted the bird survey of southern Kerala 79 years ago he was moved not just by the region's diversity of avifauna but the panoramic beauty of the setting.

If Ali was alive now, he would certainly be a sad man as serious habitat destruction and degradation pose a grim threat to survival of the bird population in the state.

This is the picture that emerges from a recent bird survey commissioned by the state Forest Department tracing Ali's footprints.

In the 1933 survey, Ali covered the Travancore and Cochin regions of Kerala, both princely states then.

Ali showed interest in surveying this region as part of an initiative of the Bombay Natural History Society to study and record the avian diversity of different regions of India.

The first survey in this series was conducted in the Hyderabad State in 1931 and the exercise covered the central Indian states of Bhopal, Gwalior, Indore and Dhar (1938), Mysore (1939) and Gujarat (1944-48), apart from Travancore and Cochin.

Ali, in his autobiography 'The fall of a sparrow' (1985) noted that "of all my regional bird surveys between the years 1930 and 1950 which I regard as the most productive period of my career, perhaps the one that gave me both as to the field work and writing up its results was the ornithological survey of Travancore-Cochin..."

He also acknowledged that the 1933 survey provided the basis for his work 'The birds of Kerala'

Interestingly, Ali's wife Tehmina was part of the survey throughout and his cousin and leading naturalist Humayun Abdulali took part in it for a short period.

After putting up a proposal to the Travancore Government, all that Ali sought was Rs 2000 to cover travel and incidental expenses, free use of inspection bungalows and forest houses and assistance from local revenue, forest and police officials. "We are lucky that a comprehensive record of birds of South Kerala has been drawn up by an authority in the field like Salim Ali. Though the methodology of bird surveys have changed since 1930s, Ali's accounts have come as a great help when we traced his trail after seven decades", C Sashikumar, who was a member of the 2010 survey, told PTI.

A book titled 'Along the trails of Salim Ali' was brought out by the state Forest Department recently based on the findings of the 2010 survey.

"Apart from the matchless beauty of South Indian hills, the southern extremity of the Sahyadri or Western Ghats, and the lushness and grandeur of their primeval evergreen forests, there was something special in much of their animal and plant life that stood out distinctly from the rest of the peninsula", Ali then observed.

Ali, who made several subsequent trips to Kerala in his eventful career, later voiced concern over the threat posed to the winged beauties by the vanishing of forests and degradation of environment.

In the late 1960s, he noted "since the survey, particularly since our Independence, I have visited Kerala every few years and been more and more depressed and scandalised each time by the mindless vandalism being perpetrated by successive state governments and crooked politicians in the devastation of virgin evergreen forests to settle repatriates and for so-called development projects..."

According to Sashikumar, a leading ornithologist and author of several works and research papers on avifauna, Ali's premonitions have come true as the forests have been destroyed largely for converting them into plantations, felling trees or for big projects like hydro-electric power.

"The recent survey has clearly brought out this poor picture and stringent conservation initiatives are essential to protect the nature from further assault," he said.

The survey, which painstakingly followed Ali's footprints, found that all species of vultures have become extinct locally in Kerala but for a small breeding population of white-backed vultures in Wayanad in north Kerala.

The survey called for an immediate vulture survey to study the current status and measures for augmenting the existing population.

On the positive side, among the 16 endemic birds, the blue-winged Parakeet, Small Sunbird, Indian Rufous Babbler and White-bellied Treepie have a seemingly healthy population.

However, high altitude birds like Grey-breasted Laughing Thrush, Black-and-Orange Flycatchers, White-bellied Shortwing and Nilgiri Flycatcher are facing serious habitat destructions and fragmentation.

Similarly, large-scale decline of Nilgiri Wood pigeon, an IUCN Red List category (a list which assesses the risk of extinction to species within a political management unit) is a cause for concern.

According to ornithologists, the Western Ghats, a major segment of Indian bio-diversity, has 16 endemic species of birds, which are found nowhere else in the world, the survey findings noted.

But this ecological hot spot is facing grim threat and its low land forests have almost completely been decimated and remaining parts severely fragmented, harming bio-diversity of the Ghats.

The recommendations include total ban on traffic through the pristine Anamudi Shola National Park, protection of the relict Shola patches as conservation reserves, regeneration of Silent Valley-Karinkulam Grass land, conservation of bird prey, regular monitoring of threatened bird species and regulation of tourism in sensitive areas like Eravikulam National Park, Sashikumar said.

Conservation of wetland areas like those around the lakes and backwaters is an area that called for urgent measures. Since the land in these areas are mostly in private possession, a community initiative is required for their protection.

Sashikumar said a bird survey of the northern district of Kerala, known as the Malabar region, was conducted a couple of years ago but it was yet to be published in the book form by the Forest Department.

New Delhi, Apr 15: As the world grapples with coronavirus, researchers have found the presence of a different kind of coronavirus -- bat coronavirus (BtCoV) --in two bat species from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu, according to a study by the Indian Council of Medical Research (ICMR).

There is no evidence or research to claim that these bat coronaviruses can cause disease in humans, said Dr Pragya D Yadav, Scientist at the National Institute of Virology (NIV), Pune and also the first author of study.

The study has been published in the Indian Journal of Medical Research,

Twenty-five bats of Rousettus and Pteropus species from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu were found positive for BtCoV in Kerala, Himachal Pradesh, Puducherry and Tamil Nadu.

"These bat coronaviruses have no relation with SARS-CoV2 responsible for the COVID-19 pandemic," Yadav said, adding that Pteropus bat species were earlier found positive for Nipah virus in 2018 and 2019 in Kerala.

"Bats are considered to be the natural reservoir for many viruses, of which some are potential human pathogens. In India, an association of Pteropus medius bats with the Nipah virus was reported in the past. It is suspected that the recently emerged severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) also has its association with bats," the objective of the study titled 'Detection of coronaviruses in Pteropus and Rousettus species of bats from different states of India' stated.

"In the present scenario of changing demography and ecological manipulations, it is challenging to have checks on the encounters of bats with other animals and humans," the study stated, highlighting that the need for active and continuous surveillance remains crucial for outbreak alerts for bat-associated viral agents with epidemic potential, which would be helpful in timely interventions.

"Although CoVs in the subfamily coronavirinae do not usually produce clinical symptoms in their natural hosts (bats), accidental transmission of these viruses to humans and other animals may result in respiratory, enteric, hepatic or neurologic diseases of variable severity. It is still not understood as to why only certain CoVs can infect people," the study said.

The scientists stressed on the need of proactive surveillance of zoonotic infections in bats.

The detection and identification of such viruses from bats also recommends cross-sectional antibody surveys (human and domestic animals) in localities where the viruses have been detected.

Similarly, if the epidemiological situation demands, evidence-based surveillance should also be conducted, the study said while emphasing on the need of developing strong mechanisms for working jointly with various stakeholders such as wildlife, poultry, animal husbandry and human health departments.

"In conclusion, our study showed detection of bat CoVs in two species of Indian bats. Continuous active surveillance is required to identify the emerging novel viruses with epidemic potential," Dr Yadav said.

Elaborating on the study, Dr Yadav said throat and rectal swab samples of two bat species -- Rousettus and Pteropus -- from seven states were screened for the bat coronvirus during which the representative samples collected from Kerala, Himachal Pradesh, Puducherry and Tamil Nadu tested positive while those from Karnataka, Chandigarh, Punjab, Telengana, Gujarat and Odisha came out negative.

The reverse-transcription polymerase chain reaction (RT-PCR) tests and sequencing were used for the confirmation of the findings.

"This is an ongoing study to understand the prevalence of the Nipah virus in bats," she said.

Patna, Jan 23: "They should go wherever they want," Bihar Chief Minister and JDU supremo Nitish Kumar said on Thursday when asked of Prashant Kishor and Pavan Verma's repeated questions about the party's stand's on the newly enacted Citizenship Act.

"It is their personal decision. They should go wherever they want. We don't have an objection. Don't look at JDU in the context of statements by some people. JDU works with determination. We have a clear stand and don't have any confusion," the Chief Minister told reporters here.

"If they have something to tell, they should come and discuss it within the party. They should go wherever they want. They have my good wishes," he said.

JDU spokesperson and national general secretary Pavan Verma has questioned his party's alliance with the BJP in Delhi Assembly polls while Kishor has more than once made his differences with the party known on the issue of the amended Citizenship Act, and National Register of Citizens.

New Delhi, Jan 16: Chief of Defence Staff (CDS) General Bipin Rawat on Thursday said that he supported a negotiated peace deal between the US and Taliban in Afghanistan.

Gen. Rawat was speaking along with other world leaders at Raisina dialogue organised by India's influential think-tank Observer Research Foundation (ORF).

Arguing that terrorism was going to stay in the world as long as states were going to use it against other states, he said it was important to prevent states from using terrorism as a "proxy war".

"The only way to deal with it was what the US did post 9/11," he said, adding that the war against terror was necessary.

However, now a peace deal with Taliban is required, Gen. Rawat said.

"It must be a negotiated peace deal so that the Taliban stops using terrorism," he added. Hinting that the US should maintain its presence in Afghanistan, the CDS said that though Afghan security forces are now equipped to fight back terror groups in Afghanistan but they still need support.

The newly appointed CDS officially confirmed that India has shifted its stance on Taliban. India has traditionally been opposed to the Pakistan-backed Taliban in Afghanistan. Thousands of Afghans were given refuge in India when they fled the country due to oppression and terrorism of the Taliban regime. India is in alignment with the democratically elected government in Kabul that the Taliban remains supported by Pakistan.
