Age of First Primary Moult in the Red-Crowned Crane Grus japonensis

Ornithological Science, 2020
The Red-crowned Crane Grus japonensis population of Hokkaido, Japan, has increased to over 1,600 individuals since near extinction in the late 19th and early 20th centuries. Adults and subadults can be distinguished by visible characteristics of their remiges; adults have pure white primaries whereas subadult birds have black primary tips and upper ...

Genetical identification of coccidia in red-crowned crane, Grus japonensis

Parasitology Research, 2006
We genetically analyzed eimerian oocysts isolated from the red-crowned crane (Grus japonensis) in Hokkaido, a northern island of Japan. Two types of oocysts of which shapes were similar to Eimeria gruis and E. reichenowi were found. Nearly the total length of the 18S ribosomal RNA gene (about 1.7 kbp in length) was amplified from single oocyst of each ...

Winter habitat selection of red-crowned crane (Grus japonensis)

Journal of Forestry Research, 2000
This paper studied the winter habitat selection of red-crowned cranes (Grus japonensis) in Yancheng National Natural Reserve, Jiangsu Province. There were six types of habitat used by red-crowned cranes, i.e. salt-works, aquiculture ponds, reed lands, grassy tidal lands, salting wormwood lands and wheat fields. The wheat field was a new type of habitat

Lead in the Red-Crowned Cranes (Grus japonensis) in Zhalong Wetland, Northeastern China: A Report

Bulletin of Environmental Contamination and Toxicology, 2016
The dietary uptake of Cd and Pb may contribute to the decline of migratory red-crowned cranes (Grus japonensis) on the Asian mainland. To uncover the relevance of this hypothesis, we determined the concentrations of Pb and Cd as well as further macro and trace elements (Ca, Mg, Cu, Zn, Hg and As) in the gastric contents, gastric wall, intestinal wall ...

Anatomy of the middle ear of the japanese crane Grus japonensis (gruidae: Aves)

Journal of Morphology, 2003
AbstractComparative anatomical studies of the avian middle ear provide structural data from which functional models can be derived. Subsequent phylogenetic analyses may reveal the phylogenetic history of taxon and the evolution of the functional model of the middle ear. We studied serial sections of a nestling of Grus japonensis.

Changes of Mercury Contamination in Red-Crowned Cranes, Grus japonensis, in East Hokkaido, Japan

Archives of Environmental Contamination and Toxicology, 2011
Red-crowned cranes (Grus japonensis) are native to eastern Hokkaido (island population), in contrast to the mainland, which migrates between the Amur River basin and eastern China-Korea peninsula. During the 1990s we found that Red-crowned cranes in Hokkaido were highly contaminated with mercury: however, the source was unknown.

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

Ecological Research, 1998
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 ...
