The ability of wild animals to live amongst humans, and persist on landscapes that experience intensive conversion to fulfill human needs provides hope for long-term conservation of many species. I got a glimpse into this phenomenon while studying the Sarus Crane in Uttar Pradesh, and am now hooked. My primary interest is to understand how this coexistence can be achieved, where and when is this coexistence not possible, and to figure out if this coexistence can be introduced to areas where they may currently be weak. On the side, the natural history and behaviour of all wild things, particularly birds, fascinates and drives me to discovery. My current focus is the habitats and landscapes in south Asia where Sarus Cranes exist, and the many other species that thrive alongside. I run Program SarusScape of the International Crane Foundation that is implemented in collaboration with NCF as the Cranes and Wetlands Programme. With my friend and colleague Luis Santiago Cano, I also Co-chair the IUCN Stork, Ibis and Spoonbill Specialist Group which allows me to work alongside a fantastic group of people worldwide interested in this group of birds.

    The role of artificial habitats and rainfall patterns in the unseasonal nesting of Sarus Cranes (Antigone antigone) in south Asia
    K S Gopi Sundar, Mohammed Yaseen, Kandarp Kathju
    Waterbirds 41(1): 80-86.

    Sarus Cranes (Antigone antigone) in south Asia breed during the rainy season (monsoon), with few nests initiated outside of the monsoon. Several hypothesis have been put forth to explain the unseasonal nesting outside the monsoon, but a careful evaluation of the hypotheses has been absent. Using a multi-year (2004-2017), multi-scale (four Indian states) data set, this study explored the factors potentially responsible for unseasonal nesting by Sarus Cranes. Nests outside the monsoon were very rare (0.3% of all nests) and were initiated when Sarus Crane pairs were in areas with artificial water sources (irrigation canals or reservoirs) or faced abnormal monsoonal conditions. Unseasonal nests were initiated only when breeding pairs had been unsuccessful in raising chicks in the previous primary nesting season. Altered cropping patterns associated with increased artificial irrigation and changing rainfall patterns appear responsible for unseasonal nesting in Sarus Cranes. Nesting of this species outside the monsoon may increase in response to the increasing changes in cropping patterns and changing rainfall conditions.

    Temporal variations in patterns of Escherichia coli strain diversity and antimicrobial resistance in the migrant Egyptian Vulture
    Pradeep Sharma, Sunil Maherchandani, B.N. Shringi, Sudhir Kumar Kashyap, K S Gopi Sundar
    Infection Ecology and Epidemeology 8:1, 1450590.



    Aims: Multiple antimicrobial resistance in Escherichia coli of wild vertebrates is a global concern with scarce assessments on the subject from developing countries that have high human-wild species interactions. We studied the ecology of E. coli in a wintering population of Egyptian Vultures in India to understand temporal changes in both E. coli strains and patterns of antimicrobial resistance.

    Methods and Results: We ribotyped E. coli strains and assessed antimicrobial resistance from wintering vultures at a highly synanthropic carcass dump in north-west India. Both E. coli prevalence (90.32%) and resistance to multiple antimicrobials (71.43%) were very high. Clear temporal patterns were apparent. Diversity of strains changed and homogenized at the end of the Vultures’ wintering period, while the resistance pattern showed significantly difference inter-annually, as well as between arrival and departing individuals within a wintering cycle.

    Significance of study: The carcass dump environment altered both E. coli strains and multiple antimicrobial resistance in migratory Egyptian Vultures within a season. Long-distance migratory species could therefore disseminate resistant E. coli strains across broad geographical scales rendering regional mitigation strategies to control multiple antimicrobial resistance in bacteria ineffective.

    Hunting or habitat? Drivers of waterbird abundance and community structure in agricultural wetlands of southern India
    Ramachandran, R., Ajith Kumar, K S Gopi Sundar, Ravinder Singh Bhalla
    Ambio, 46(5): 613-620. DOI: 10.1007/s13280-017-0907-9

    The relative impacts of hunting and habitat on waterbird community were studied in agricultural wetlands of southern India. We surveyed wetlands to document waterbird community, and interviewed hunters to document hunting intensity, targeted species, and the motivations for hunting. Our results show that hunting leads to drastic declines in waterbird diversity and numbers, and skew the community towards smaller species. Hunting intensity, water spread, and vegetation cover were the three most important determinants of waterbird abundance and community structure. Species richness, density of piscivorous species, and medium-sized species (31–65 cm) were most affected by hunting. Out of 53 species recorded, 47 were hunted, with a preference for larger birds. Although illegal, hunting has increased in recent years and is driven by market demand. This challenges the widely held belief that waterbird hunting in India is a low intensity, subsistence activity, and undermines the importance of agricultural wetlands in waterbird conservation.

    Factors affecting provisioning times of two stork species in lowland Nepal
    K S Gopi Sundar, Bijay Maharjan, Roshila Koju, Swati Kittur, Kamal Raj Gosai
    Waterbirds, 39: 365-374. doi: http://dx.doi.org/10.1675/063.039.0406

    The ecology of stork colonies in south Asia are very poorly understood. Factors affecting provisioning times by adults were evaluated at nests of two stork species, the Asian Openbill (Anastomus oscitans) and the Lesser Adjutant (Leptoptilos javanicus), in lowland Nepal where the landscape is dominated by multi-cropped agriculture fields. Analyses focused on understanding if provisioning times are influenced more due to colony-level variables, wetlands around colonies, or season. Using generalized additive mixed models and the information-theoretic approach, colony-level variables (brood size and chick age) showed non-trivial associations with provisioning times (substantially better than the null model). Univariate models with colony size and wetlands had poor support (worse than the null model). Season, which represented the changing cropping patterns, rainfall, and wetness on the landscape, was the most important variable for both species. The combination of season and wetlands was very important for provisioning Asian Openbills whose chicks fledged during the monsoon (July–October), but not for Lesser Adjutants whose chicks fledged in the drier winter months (November–February). Results strongly suggest that changing cropping patterns to a drier monsoonal crop, or reductions in wetland extents, will be detrimental to storks in Nepal.

    Wetland loss and waterbird use of wetlands in Palwal district, Haryana, India: The role of agriculture, urbanization and conversion to fish ponds
    Wetlands. DOI 10.1007/s13157-014-0600-8

    PDF, 1.15 MB

    Wetlands in tropical and sub-tropical landscapes
    are experiencing changes and loss due to urbanization and
    intensive human use, but there is sparse detailed understanding
    of how these affect use by wetland-dependent birds.
    Urbanization and conversion of community wetlands to private
    fish ponds are occurring rapidly in Haryana state in north
    India. We conducted a study in Palwal district, Haryana in
    2013–2014 to simultaneously understand (i) rates and reasons
    for wetland loss between 1970s and 2000s, and (ii) relative
    importance of location (towns/ villages versus those amid
    agriculture) versus site-specific variables on the winter abundance of 31 waterbird species in these fish ponds. Wetland
    extent reduced by 52 %, and average wetland size reduced by
    42 % between 1970s and 2000s. Expansion of urban areas
    converted 105 agricultural wetlands to town wetlands.
    Wetlands of different locations could not be differentiated
    using waterbird abundance suggesting that wetland conditions
    have been homogenized, in part due to conversions to fish
    ponds and in part due to urban expansions. Focal waterbird
    abundance was affected more due to human activities relative
    to location or vegetation. A complex combination of current
    management practices and historical determinants of wetland persistence appear to be driving waterbird use of wetlands in
    locations like Palwal.

    Can wetlands maintained for human use also help conserve biodiversity? Landscape–scale patterns of bird use of wetlands in an agricultural landscape in north India
    Biological Conservation 168: 49-56. http://dx.doi.org/10.1016/j.biocon.2013.09.016

    Wetlands in tropical agricultural landscapes are maintained largely by local institutions explicitly for human use, which is assumed to deter biodiversity. Conservation efforts have been biased towards protecting large wetlands that are assumed to be adequate to conserve the majority of species of focal taxa, usually birds. These assumptions remain untested, and landscape-scale conservation planning for wetlands is largely absent, as is a generalised understanding of wetland use by focal taxa. We designed a landscape-scale survey to understand patterns and processes determining beta diversity of birds using agricultural wetlands in south-western Uttar Pradesh, India where wetlands have experienced prolonged and intensive human use for several centuries. Observed bird species richness (99 species in 28 wetlands) is the highest known for any agricultural landscape in south Asia signifying that even intensive human use of wetlands does not necessarily deter their ability to retain biodiversity. Birds exhibited strong scale
    dependent wetland use underscoring the need to conserve wetlands of varying sizes and at varying densities on the landscape. Beta diversity was due largely to species turnover (0.877) with minimal effect due to nestedness (0.055) suggesting that conserving a few large wetlands will not adequately meet goals of conserving the majority of wetland bird species. Prevailing assumptions regarding biodiversity conservation in tropical agricultural wetlands require being revised, and a landscape-scale approach that incorporates ecological realities is needed. Incorporating local institutions alongside formal protectionist methods offer a potential win–win situation to maximise conservation of biodiversity in tropical agricultural wetlands.
