Immigration of banded Great Cormorants to inland areas
Japanese Journal of Ornithology, 2009 本研究では，広域的に移動するカワウPhalacrocorax carboにおいて，山梨県で発見された標識個体の記録から，沿岸域を中心とする大規模コロニーから内陸部への移入および飛来の傾向を調査した．2003年から2008年までの間に，銃器による捕獲で8個体，釣り針による捕獲で2個体，観察により3個体，計13個体の標識されたカワウが発見された．発見された水系別にみると，駿河湾に注ぐ富士川水系では，5個体全てが愛知県以西で標識された個体であった．一方，上流域が山梨県東部にあり相模湾，東京湾へと注ぐ相模川および多摩川では，8個体の標識されたカワウは，全て関東地方沿岸域で標識された個体であった．富士川と相模川，多摩川とで，カワウの標識された地域には明瞭な差異がみられ，富士川水系へは中部，近畿地方から，相模川，

An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea
Fisheries Oceanography, EarlyView.ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.

Great cormorant predation on Cisalpine pike: a conservation conflict [PDF]
European Journal of Wildlife Research, 2015 In the last decades, the distribution and abundance of great cormorants have extraordinarily increased throughout Europe. Many studies reported that great cormorants may impact fish populations not only by consuming large number of individuals but also by wounding them.

Seasonal climatic niche and migration movements of Double‐crested Cormorants
Ecology and Evolution, 2022 Avian migrants are challenged by seasonal adverse climatic conditions and energetic costs of long‐distance flying. Migratory birds may track or switch seasonal climatic niche between the breeding and non‐breeding grounds. Satellite tracking enables avian

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds
Journal of Anatomy, EarlyView.The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.
