Book Shelf .................................................................................................................. 49 Interpreting and quantifying ecosystem services of any component of the ecosystem in monetary value (commodification) is not easy. But in a consumerist society, this may be the only way to convince the policy makers as well as the layman on the importance of mammals, birds, insects, spiders, fungi, plants etc. A good example of this type of interpretation was Harold A. Mooney provided by Markandya, A., et al., 2008 in t their paper MALABAR TROGON Vol.14 (1-3) Jan-Dec. 2016 3 ‘Counting the cost of vulture decline — An appraisal of the human health and other benefits of vultures in India’( Ecological Economics, doi:10.1016/j. ecolecon.2008.04.020). In this paper, the authors assessed, through economic valuation, the outcome of the catastrophic population crash (99.9%) of Gyps vultures in India from 1992 to 2007 caused by the use of the veterinary drug diclofenac. The disappearance of vultures caused accumulation of rotting domestic ungulate carcasses in most parts of India resulting in environmental pollution and an increased incidence of infectious diseases among people and livestock. Other non-obligate scavengers like feral dogs, rats etc. increased in numbers causing the spread of diseases like leptospirosis and rabies. India has the highest rate of human rabies infections in the world, and 95% of human deaths here due to rabies are caused by dog bite. An increase of 72.5 lakhs feral dogs in the period 1992 to 2006 has been calculated by the Census Ministry of Agriculture in the 17th Livestock Census, 2003. 1.67 crore dog bites are estimated for an year leading to an additional 3.85 to 3.97 crore dog bites and 48,000 human deaths. The cost for the treatment of the bites alone was estimated to be Rs.1310 to Rs.2440 crore. The authors estimated that the total health cost due to the decline of vultures could be Rs.99,800 to Rs.1,09,500 crore. Apart from this, the Parsi community had a loss of Rs 16 lakhs as their ‘sky burial’ custom had to be replaced other means. Overall, this is a huge amount considering the low annual income of the majority of the common people who were the victims. This is the consequence of the decline in the population of one group of birds, explained in terms of money, that too a very conservative estimate. But this is enough to show the impact on the loss of a species of bird to humanity as a whole. The phenomenal cost of the long term programme on the conservation breeding and reintroduction of these critically endangered species, which will run into billions of rupees, also has to be considered. Thus, quantifying the services provided by Nature may give us a lot of new insights about the resources that we squander without a second thought. Write us... Send your suggestions and articles to C.

[email protected] Introduction álim Ali reported a definitive list of 356 species in his book Birds of Kerala published in 19691. After this publication, there have been Sseveral compilations to update our knowledge of the birds of the region and keep the state checklist up-to-date. Here, I attempt to analyse the discovery patterns of new bird species added to the Kerala checklist after Ali’s work and to see if this pattern is dependent on the changes in bird diversity or changes in the profile of the birdwatcher network

  • NSS Bird Group Report – Sept 2019
    NSS Bird Group Report – Sept 2019 September 2019 marked the appearance of rarities such as the Glossy Ibis, Black-naped Monarch, Blue Rock Thrush, and Japanese Paradise Flycatcher; as well as the first arrivals of many migrants. Glossy Ibis Sighting Photo-montage of the Glossy Ibis at Kranji Dam on 29 September 2019 by Goh Cheng Teng The Glossy Ibis, Plegadis falcinellus, is a widely distributed species that is found in Europe, Africa, Asia, Australia, Central and North America. However, it is a very rare vagrant in Singapore. The sighting on 28 and 29 September 2019 by Raghav and Goh Cheng Teng, respectively, was our fifth sighting to date. Prior sightings were at Lorong Halus in 12-16 June 1984, Sungei Buloh in May 1989, Sime Road in October 1992, and November 2007. Wells (1999: 107) noted that the species is a vagrant in Peninsular Malaysia and highlighted that the sightings in 1984 and 1989 may have been wild sightings; captive birds were ruled out since the sightings comprised of adults and juveniles. Traded birds tended to be of a uniform age, since birds would be taken as fledglings. Central Catchment Nature Reserve (CCNR) & Fringes Possibly first for the season, a Forest Wagtail, Dendronanthus indicus, was spotted in flight on 2 September 2019 at Jelutong Tower by Francis Yap. Another was spotted within CCNR on 6 September 2019 by Dillen Ng; who also spotted an Arctic Warbler, Phylloscopus borealis, on the same day. Also on 6 September 2019, an Eastern Crowned Warbler, Phylloscopus coronatus, was spotted at Jelutong by Francis Yap.

  • Cacomantis Merulinus) Nestlings and Their Common Tailorbird (Orthotomus Sutorius) Hosts Odd Helge Tunheim1, Bård G
    Tunheim et al. Avian Res (2019) 10:5 https://doi.org/10.1186/s40657-019-0143-z Avian Research RESEARCH Open Access Development and behavior of Plaintive Cuckoo (Cacomantis merulinus) nestlings and their Common Tailorbird (Orthotomus sutorius) hosts Odd Helge Tunheim1, Bård G. Stokke1,2, Longwu Wang3, Canchao Yang4, Aiwu Jiang5, Wei Liang4, Eivin Røskaft1 and Frode Fossøy1,2* Abstract Background: Our knowledge of avian brood parasitism is primarily based on studies of a few selected species. Recently, researchers have targeted a wider range of host–parasite systems, which has allowed further evaluation of hypotheses derived from well-known study systems but also disclosed adaptations that were previously unknown. Here we present developmental and behavioral data on the previously undescribed Plaintive Cuckoo (Cacomantis merulinus) nestling and one of its hosts, the Common Tailorbird (Orthotomus sutorius). Methods: We discovered more than 80 Common Tailorbird nests within an area of 25 km2, and we recorded nestling characteristics, body mass, tarsus length and begging display every 3 days for both species. Results: Plaintive Cuckoo nestlings followed a developmental pathway that was relatively similar to that of their well-studied relative, the Common Cuckoo (Cuculus canorus). Tailorbird foster siblings were evicted from the nest rim. The cuckoo nestlings gained weight faster than host nestlings, and required 3–9 days longer time to fedge than host nestlings. Predation was high during the early stages of development, but the nestlings acquired a warning display around 11 days in the nest, after which none of the studied cuckoo nestlings were depredated. The cuckoos’ begging display, which appeared more intense than that of host nestlings, was initially vocally similar with that of the host nestlings but began to diverge from the host sound output after day 9.

  • Understanding REPORT of the WESTERNGHATS ECOLOGY EXPERT PANEL
    Understanding REPORT OF THE WESTERNGHATS ECOLOGY EXPERT PANEL KERALA PERSPECTIVE KERALA STATE BIODIVERSITY BOARD Preface The Western Ghats Ecology Expert Panel report and subsequent heritage tag accorded by UNESCO has brought cheers to environmental NGOs and local communities while creating apprehensions among some others. The Kerala State Biodiversity Board has taken an initiative to translate the report to a Kerala perspective so that the stakeholders are rightly informed. We need to realise that the whole ecosystem from Agasthyamala in the South to Parambikulam in the North along the Western Ghats in Kerala needs to be protected. The Western Ghats is a continuous entity and therefore all the 6 states should adopt a holistic approach to its preservation. The attempt by KSBB is in that direction so that the people of Kerala along with the political decision makers are sensitized to the need of Western Ghats protection for the survival of themselves. The Kerala-centric report now available in the website of KSBB is expected to evolve consensus of people from all walks of life towards environmental conservation and Green planning. Dr. Oommen V. Oommen (Chairman, KSBB) EDITORIAL Western Ghats is considered to be one of the eight hottest hot spots of biodiversity in the World and an ecologically sensitive area. The vegetation has reached its highest diversity towards the southern tip in Kerala with its high statured, rich tropical rain fores ts. But several factors have led to the disturbance of this delicate ecosystem and this has necessitated conservation of the Ghats and sustainable use of its resources. With this objective Western Ghats Ecology Expert Panel was constituted by the Ministry of Environment and Forests (MoEF) comprising of 14 members and chaired by Prof.

  • The Continuing Decline of Hindus in Kerala
    The continuing decline of Hindus in Kerala Kerala—like Assam, West Bengal, Purnia and Santhal Pargana region of Bihar and Jharkhand, parts of Western Uttar Pradesh and Uttarakhand, Mewat of Haryana and Rajasthan, and many of the States in the northeast—has seen a drastic change in its religious demography in the Census period, beginning from 1901. The share of Indian Religionists in Kerala, who are almost all Hindus, has declined from nearly 69 percent in 1901 to 55 percent in 2011, marking a loss of 14 percentage points in 11 decades. Unlike in the other regions mentioned above, in Kerala, both Christians and Muslims have considerable presence and both have gained in their share in this period. Of the loss of 14 percentage points suffered by the Indian Religionists, 9.6 percentage points have accrued to the Muslims and 4.3 to the Christians. Christians had in fact gained 7 percentage points between 1901 and 1961; after that they have lost about 3 percentage points, with the rapid rise in the share of Muslims in the recent decades. This large rise in share of Muslims has taken place even though they are not behind others in literacy, urbanisation or even prosperity. Notwithstanding the fact that they equal others in these parameters, and their absolute rate of growth is fairly low, the gap between their growth and that of others remains very wide. It is wider than, say, in Haryana, where growth rates are high and literacy levels are low. Kerala, thus, proves that imbalance in growth of different communities does not disappear with rising literacy and lowering growth rates, as is fondly believed by many.

P. MAHOOD, A. J. I. JOHN, J. C. EAMES, C. H. OLIVEROS, R. G. MOYLE, HONG CHAMNAN, C. M. POOLE, H. NIELSEN & F. H. SHELDON Based on distinctive morphological and vocal characters we describe a new species of lowland tailorbird Orthotomus from dense humid lowland scrub in the floodplain of the Mekong, Tonle Sap and Bassac rivers of Cambodia. Genetic data place it in the O. atrogularis–O. ruficeps–O. sepium clade. All data suggest that the new species is most closely related to O. atrogularis, from which genetic differences are apparently of a level usually associated with subspecies. However the two taxa behave as biological species, existing locally in sympatry and even exceptionally in syntopy, without apparent hybridisation. The species is known so far from a small area within which its habitat is declining in area and quality. However, although birds are found in a number of small habitat fragments (including within the city limits of Phnom Penh), most individuals probably occupy one large contiguous area of habitat in the Tonle Sap floodplain. We therefore recommend it is classified as Near Threatened on the IUCN Red List. The new species is abundant in suitable habitat within its small range. Further work is required to understand more clearly the distribution and ecology of this species and in particular its evolutionary relationship with O. atrogularis. INTRODUCTION and its major tributaries (Duckworth et al.
