The AFCoW News & Events section will provide an outlet for news reports and commentary on waterbirds in the Asian Flyways as well as reporting on new publications (see References). A schedule of Events will be provided for meetings, workshops, and other activities that may interest AFCoW members. Please feel free to send topics for News & Events to the organizers through the contact page or listserve.

AFCoW special section: Predicting Seasonal Bird Migration with Birdcast

Predicting Seasonal Bird Migration with Birdcast

Dr. Kyle Horton

Assistant Professor Colorado State University Fish, Wildlife, and Conservation Biology

Billions of animals cross the globe each year during seasonal migrations, but efforts to monitor them are hampered by the unpredictability of their movements. We developed a bird migration forecast system at a continental scale by leveraging 23 years of spring observations to identify associations between atmospheric conditions and bird migration intensity. Our models explained up to 81% of variation in migration intensity across the United States at altitudes of 0 to 3000 meters, and performance remained high in forecasting events 1 to 7 days in advance (62 to 76% of variation was explained). Avian migratory movements across the United States likely exceed 500 million individuals per night during peak passage. Bird migration forecasts will reduce collisions with buildings, airplanes, and wind turbines; inform a variety of monitoring efforts; and engage the public.

Analysis of Wetland Prioritization for EAAF Migratory Waterbird Conservation

In the global fight against biodiversity loss, biologists rely on spatial prioritization approaches to plan allocation of limited conservation resources. I qualitatively analyze the widespread population percentage approach to wetland prioritization for migratory waterbird conservation in the EAAF and ask why connectivity-based inclusion criteria are lacking. I suggest one explanation may be how birds are valued in sub-national conservation politics. At its root, the difference in usage between population percentages and connectivity metrics might be the scale difference between counts of birds and tagged individuals. When advocating site conservation against economic interests, ecological values often must be defended using a way of thinking that fails to recognize the legitimacy of knowledge obtain from small numbers of tagged birds. Migratory connectivity is critical for the persistence of waterbird populations, yet it is understood at the scale of the individual bird. A shift toward recognizing the value of individual birds’ experiences is a first step toward achieving effective population-level conservation.

Migratory pattern of coastal birds through Kanyakumari, India with special emphasis on terns

Kanyakumari being located at the southern tip of peninsular India and at the meeting place of two seas with the Indian Ocean, this site attains significance for migratory birds that winter and pass through India. These sites act as a stopover/ refuelling site during the southward migration (August to mid-October) for the birds migrating to the southern hemisphere countries. Similarly, many species that might not have passed through this site during the southward migration occur during the northward migration (mid-February to early April). This three-decade study documented the changes in the population trends of several migratory species, especially in Crested terns. The mass movements recorded in several tern species which did not happen during northward passage indicate that the species take different migratory routes for their northward and southward journeys. The major migratory groups consist of terns followed by waders and flamingos. The dominant species during southward passage are predominantly marine terns and a small number of shorebirds. During winter the dominant groups are mostly ducks and several species of waders and flamingos. Species that utilise these sites as a stopover during northward migration are predominantly waders and marsh terns (Whiskered, Gull-billed, Little & Saunders’s terns). Habitat specialists like Grey Plover, Terek Sandpiper, Common Greenshank and Ruddy Turnstone also occur at the sites in more numbers during northward passage. Contrary to the other sites like Chilika and Point Calimere, this area supports Whiskered Tern only during the northward passage. It can currently supports the largest population of Common Terns (80,000 to 1,00,000), Lesser Crested Terns (c. 20,000), and Greater Crested Terns (c. 80,000) which stayed briefly during northward migration. The BNHS’s bird ringing studies at Kanyakumari have produced interesting recoveries on Common tern, Lesser Crested tern, and Whiskered tern.

Dr. Nyambayar Batbayar: Tracking the migration of threatened White-naped cranes from Mongolia and its conservation implications

Since 2014, we have tracked over 80 White-naped cranes from various locations at their breeding grounds in eastern Mongolia. The individuals we tracked belong to the western flyway of the species where most migrate between Mongolia and Poyang Lake. There are some clear indications about the migration divide between the two flyways. Several individuals tracked from easternmost Mongolia belonged to the eastern flyway reaching Korean Peninsula. It seems to be the two flyways are not completely separated. We have identified several key stopover sites, which we believe the species’ survival depends on them. One of them is Duolin, a site located in southern Inner Mongolia. The location was a hub for the cranes in the northern part of the range. This raises several questions, including the area’s health and introduction of infectious diseases, etc.
