 鳥吉英伸 【獣医師】カラスの高知能、カラス撃退? #動物 #野生動物 #鳥   鳥吉英伸 Dr. Hidenobu Toriyoshi

カラスは非常に賢く、人間の小学校低学年、すなわち6から8歳程度の知能を持つと言われています。 「石を投げつけられた」「水をかけられた」といった被害体験を覚えるだけでなく、自分に害を与える人間の顔や服装まで記憶し、仕返しを企てることもあります。 カラスを追い払うための罠や仕掛けについても、単なる脅しで実害がないと分かると効果を失うのは、その高い知能ゆえです。 さらに、カラス同士で個体の外見や鳴き声を判別し、危険人物などの情報を親子間や仲間間で共有すると言われています。 1羽のカラスを攻撃すると、集団で仕返しにくることもあり得るため、十分な注意が必要です。 ゴミ袋の中からカラスが食べ物を認識できるのは、高い知能だけでなく優れた視力と色の識別能力にも依存しているようです。 人間と比較すると、カラスの視力は5倍であり、赤、緑、青に加えて紫外線も見えます。 人間には虹は7色に見えますが、カラスには14色以上に見えている可能性があります。 雑多なものが混在する半透明のゴミ袋の中からでも、エサを見分けます。

カラスは、かわいいペットにもなります。 ▼鳥吉英伸 経歴、鳥吉英伸 現在 東京大学大学院医学系研究科で博士課程を卒業し、医学博士および獣医師の資格を取得。さらに、アメリカ獣医師会および米国カリフォルニア州獣医師会のメンバーでもある。また、獣医科大学大学院で教鞭を執り、動物病院の院長も務めている。 彼はアメリカのフロリダ州シーワールド水族館やカリフォルニア州サンディエゴ動物園などで獣医師としての経験を積み、様々な動物種（哺乳類、鳥類、爬虫類、両生類、魚類、昆虫、無脊椎動物）の治療に携わってきました。その腕前は世界中で高く評価され、彼は二万もの動物種の治療に貢献しています。 彼はアメリカ獣医師会の「モデストマクリーン賞」を受賞し、これは日本人として初めての快挙です。彼はまさに珍しい獣医師、珍獣ドクターとしてその名を知られています。 【鳥吉英伸 画像】 ▼関連動画 奇跡のカリスマ獣医2 鳥吉英伸【日本語字幕版】Prof. Dr. Hidenobu Toriyoshi, Ph.D., DVM, D.M.Sc. https://www.youtube.com/watch?v=tikT3im2Xc0 奇跡のカリスマ獣医 鳥吉英伸【1分切り抜き】「昆虫、魚から象、クジラまで治療する獣医さん」Prof. Dr. Hidenobu Toriyoshi, Ph.D., DVM, D.M.Sc. https://www.youtube.com/watch?v=947uHPtJY70 奇跡のカリスマ獣医2 鳥吉英伸（アニメ版） https://www.youtube.com/watch?v=Zequr0t4H7U 【都市伝説】未知なる絆 - 獣医の異次元冒険と動物たちとの対話。アヤワスカの力で描く、動物と人間の心の物語【日本語字幕】 https://www.youtube.com/watch?v=OiXYO2Wtw5Q 小説「獣医の細道」本の要約【日本語字幕】 https://www.youtube.com/watch?v=sJwY-xurKd8 小説「獣医の細道」本の紹介（ショート動画）【日本語字幕】 https://www.youtube.com/shorts/aziyBccitXg 獣医の細道 - 世界で輝く若き凄腕獣医師の物語 “東京の獣医師ムラの陰謀と挑戦。日本の小動物病院業界の闇を暴く” https://www.youtube.com/watch?v=3wl5MYewGvc サンディエゴ動物園の奇跡の獣医師: 日本人初の挑戦者 "2万種の動物との感動の診療日記と思い出の瞬間" 鳥吉英伸 Prof. Dr. Hidenobu Toriyoshi, DVM, Ph.D【日本語字幕】 https://www.youtube.com/watch?v=xqJZtIihOrw 【鳥吉英伸】王のペットたち！世界最高峰のスゴ腕獣医との出会い「鳥吉博士とカンボジア国王のモンキーズ。異国の王宮ペットたちの物語」 https://www.youtube.com/watch?v=8GDNEUieRIQ カバの歯科冒険、メロンで虫歯戦士 "カバの歯科治療の驚きの一瞬" 歯の秘密と治療の舞台裏【切り抜き】 https://www.youtube.com/watch?v=wwMzhTRThhQ The highest skilled veterinarian who treats everything from insects to elephants, Hidenobu Toriyoshi [English subtitled movie]-short movie https://www.youtube.com/shorts/Oaud7PjMjXs The highest skilled veterinarian who treats everything from insects to elephants, Hidenobu Toriyoshi [English subtitled movie] https://www.youtube.com/watch?v=upzAsplqvsg Pets of the King!

Crows are known to be highly intelligent. #animals #birds #shorts Dr. Hidenobu Toriyoshi

Crows are known to be highly intelligent, possessing the cognitive abilities of a human child in the early elementary school years, roughly between 6 and 8 years old. They not only remember experiences of being pelted with stones or splashed with water but also store information about the faces and attire of humans who pose a threat, sometimes plotting revenge. The effectiveness of traps and deterrents against crows diminishes when they realize there is no actual harm involved, owing to their high intelligence. Furthermore, crows are capable of distinguishing between individual appearances and calls, sharing information about potential dangers among family and peers. Attacking a single crow may lead to retaliation from a group, emphasizing the need for considerable caution. The ability of crows to recognize food within garbage bags is attributed not only to their high intelligence but also to their exceptional visual acuity and color discrimination. In comparison to humans, crows have five times better vision and can see ultraviolet light in addition to red, green, and blue. While humans perceive a rainbow as having seven colors, crows may see more than 14 colors. Even within a semi-transparent garbage bag containing a mix of miscellaneous items, crows can discern and identify food.
