Satellite tracking of the migration of the red‐crowned crane Grus japonensis

Abstract

Autumn migration routes of red‐crowned cranes, Grus japonensis, from two continental east Asian sites were documented in detail by satellite tracking. Two routes were identified: a 2200 km western route from Russia's Khingansky Nature Reserve to coastal Jiangsu Province, China; and a 900 km eastern route from Lake Khanka (Russia) to the Korean Peninsula and the Demilitarized Zone. The most important rest‐sites were identified as Panjin Marsh (China), coastal mudflats south‐east of Tangshan City (China), the Yellow River mouth (China), Tumen River mouth (North Korea/China/Russia), Kumya (North Korea) and Cholwon (Korean DMZ). Movements within the wintering range were also recorded, including complex commuting between sites by individual cranes and patterns of daily movements within sites. These data should prove useful for conservation of the flyway.

A simple population viability analysis of Tancho (Grus japonensis) in southeastern Hokkaido, Japan

“…Data used in this study 4 The third author and his colleagues have conducted detailed surveys since the Simulation of the future population dynamics using stage matrix 17 From the above data, we calculated factors for a stage matrix that were used for was as low as 0.52% (3/580) in our surveys, the banded crane data were highly reliable.…”

Satellite tracking and avian conservation in Asia

“…Satellite transmitters were made by NTT, Toyo Communication Equipment, and Microwave Telemetry, and never weighed more than 2% of the target species' body weight (e.g. Higuchi et al 1996Higuchi et al , 1998Kanai et al 1997). Duty cycles were set with the desired length of the tracking period in mind (e.g.…”

Tracking the Autumn Migration of the Bar-Headed Goose (Anser indicus) with Satellite Telemetry and Relationship to Environmental Conditions

“…Eleven bar-headed geese (numbers 82086, 67695, 82079, 82084, 82080, 82085, 82082, 82081, 82076, 74901, 74902) with continuous tracking data available through the autumn migration were selected for the analysis. They were tracked on their 2008 autumn migration from Qinghai Lake to their wintering grounds, and their migration was compared to other birds such as red-crowned cranes (Grus japonensis) [16] and Honey-buzzards (Pernis apivorus) [17].…”
