Breeding and Distribution of Grus japonensis in the Southern Part of Tokachi District, Hokkaido
Japanese Journal of Ornithology, 1983 Observations were made on the Japanese Crane Grus japonensis at Taiki in the southern part of Tokachi District, Hokkaido, for 14 years from 1969 to 1982. Cranes were first recorded at Taiki in 1953 and have been observed between late March and late December every year since 1965.

Acoustic cues to development of African Penguins (Spheniscus demersus) begging calls
Ibis, Volume 167, Issue 1, Page 286-294, January 2025.Avian begging calls mediate parent–offspring conflict and direct parental care to genetically related progeny. We found that the fundamental frequency of begging calls of African Penguins Spheniscus demersus decreases as the penguins age and gain mass, before reaching a lower plateau when the chick reaches about 1 kg.

Distribution of the Red-crowned Crane Grus japonensis in the Breeding Season of 1986
Japanese Journal of Ornithology, 1986 The distribution and breeding status of the Red-crowned Crane Grus japonensis were recorded from the air. Flights were made in a light plane over marshes, along rivers and lakes, in eastern Hokkaido from May 31 to June 2, 1986. Flying time totalled 15 hours and the distance covered was about 1, 810 km.Fifty seven incubating and brooding paris were ...

野生动物学报, 1983 丹顶鹤（Grus japonensis）又名仙鹤,是国家一类保护动物。为摸清其生态习性,我们从1976年开始,先后对85只野生丹顶鹤的雏鸟,进行自然条件下的半散放野养驯化。其中育成81只,死亡4只,成活率达95.3％,1981年达100％。这项工作的初步成功,对于恢复丹顶鹤的种群数量,提高观赏价值,开展科学研究都有重要意义。

Persistent organic pollutants in red-crowned cranes (Grus japonensis) from Hokkaido, Japan
Ecotoxicology and Environmental Safety, 2018 The red-crowned crane (Grus japonensis) from eastern Hokkaido is classified as a Special Natural Monument in Japan. In this study, we determined the concentrations of persistent organic pollutants (POPs) in red-crowned crane muscle tissues (n = 47). Polychlorinated biphenyls (PCBs) had the highest median concentration (240ng/g lipid weight), followed ...

基于CHD基因和EE0.6基因遗传多态鉴定白枕鹤、丹顶鹤性别研究报告
野生动物学报, 2018 白枕鹤(Grus vipio)和丹顶鹤(Grus japonensis)是中国重点保护动物,为单态性鸟,很难通过外观和形态来进行性别鉴定,给人工繁殖造成很大困难。研究已发现CHD基因和EE0.6序列片段大小在非平胸鸟类W、Z染色体上均存在差异。基于此,本研究以无锡市动物园饲养的白枕鹤和丹顶鹤为研究对象,经PCR实验,对白枕鹤和丹顶鹤CHD基因和EE0.6序列的相关片段进行了特异性扩增。结果显示,这2种方法PCR扩增结果一致,并根据这一结果进行白枕鹤、丹顶鹤配对,均成功孵化出后代,表明该PCR鉴定结果可靠,
