First detailed survey of waterbirds in Tirunelveli and Tuticorin districts, Tamil Nadu, India [PDF]

, 2013
The semi-arid districts of Tirunelveli and Tuticorin in the southern Indian state of Tamil Nadu consist of numerous wetlands in the form of irrigation tanks, interconnected by an ancient network of canals, and fed by the rivers originating from the ...

Begging behavior as an honest signal of need and parent–offspring association during the postfledging dependency period

Ecology and Evolution, 2019
Honest signaling mechanisms can function to appropriate care to hungry offspring and avoid misdirected care of unrelated offspring. Begging, the behavior by which offspring solicit food and parental care, may be an honest signaling mechanism for need, as

Ruddy Shelduck Tadorna ferruginea home range and habitat use during the non-breeding season in Assam, India [PDF]

India is an important non-breeding ground for migratory waterfowl in the Central Asian Flyway. Millions of birds visit wedands across the country, yet information on their distribution, abundance, and use of resources is rudimentary at best.

Applicability of ptilochronology as a conservation tool in waterbird studies

Ecological Indicators, 2011
Ptilochronology is a cost effective tool for determining the nutritional condition of birds. The technique uses the daily growth of feathers to decipher diet and habitat quality as well as contaminant load. To date, most studies using ptilochronology have focused primarily on passerines.

Drone‐based radiotelemetry and imagery systems provide an advantage over traditional techniques for estimating survival of dependent juveniles

Wildlife Society Bulletin, EarlyView.
We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.

Spatial scales matter in designing buffer zones for coastal protected areas along the East Asian-Australasian Flyway

Global Ecology and Conservation
Coastal protected areas are increasingly threatened by urbanization, posing significant risks to wetland biodiversity. Consequently, the recognition of buffer zones as essential for reducing anthropogenic impacts on protected areas has grown.

Regional conservation planning tool: A spreadsheet model to support spatial prioritization and resource allocation decisions

Wildlife Society Bulletin, EarlyView.
Abstract Prioritization is a central component of natural resource management because conservation needs routinely exceed available resources. Waterfowl and wetland conservation programs in North America are at the forefront of landscape‐scale prioritization and transboundary management decisions due to the migratory nature of ducks, geese, and swans ...

Multi-scale factors revealed contrasting impacts on Waterbird composition and Beta diversity across wetlands in an Afrotropical landscape

Global Ecology and Conservation
Global loss and human-induced degradation of wetlands are presumed to impact waterbirds. To understand how human activities and habitat features drive waterbird species composition, there is need to understand beta-diversity and its components of ...
