The Amur tiger reached Yakutia. This is a rare event, but not new - visits to the northern region have been recorded before. Some of them were confirmed, and some remained at the level of rumors. Now, thanks to the development of technologies and means of communication, more can be learned about the phenomenon.
The tracks of the Amur tiger at the mouth of the Bollokhtokh River, the right tributary of the Uchur River (58 ° 02'08 "N, we do not specify the longitude deliberately) were met by Andrei Ivanov, observer pilot of the Uchur air department of the Yakutsk Avialesokhrana air base. He made an unusual find on November 9, filmed her in the photo and video. Traces in Yakutia, when they were discovered by Andrei Ivanov, were fresh. The author of the video voiced the width of the "heel" as 12 cm. However, when you apply your hand to the print, you can see that it is almost equal to the palm. The average width of the palm at the base of the fingers in men is 9 cm. Therefore, the imprint of the width of the footprint is approximately 9-9.5 cm. Andrei applies his palm to the print of the hind paw, and the print of the front paw in tigers is about 1 cm larger than the hind paw. It turns out that the "clean" size of the front paw print - it is it that is measured during counts and for identification of tigers - is 10-10.5 cm. This is most likely a young male. From the place of their discovery to the valley of the Uda River is about 400-450 km. The distance is long, but not a record one, given that the crossing of 20-30 km per night for the Amur tiger is a common thing. It will be possible to draw up a more detailed route of the tiger and try to determine whether it is the same tiger later, after collecting all the information. So, for example, not far from the place where the tracks were found, about 30 kilometers away, there is a camp of reindeer herders and it is possible that they also saw tracks or even the tiger itself. If this is a different individual, then it is already the second wanderer tiger in the past few months. Quote: In any case, for such long transitions at negative temperatures, the tiger needs strength and, therefore, food. Most likely the tiger is hunting reindeer. In addition to them, in those places there are red deer and roe deer, many hares and Yakut horses on free grazing. Despite the presence of potential victims, another reason for wandering is the search for a habitat. Quote: The first documented information about the appearance of a tiger in Yakutia dates back to 1827. tiger visits to Yakutia were recorded 3 more times. Penetrations of the predator resumed after more than half a century. In the XX century. tiger visits were recorded 5 times, until the end of the 70s. The last case of finding tracks of a tiger on the territory of Yakutia occurred in 2012 on the ridge. Suntar-Khayata (Tompon district), 350-400 km north of the places of previous appearance (not scientifically confirmed). More details about these cases can be found in the scientific work of A.V. Argunova "On the penetration of the Amur tiger into Yakutia." http://amur-tiger.ru/ru/press_center/news/1656/

Cambridge University Press, Cambridge, UK (1999): 71-99.  This particular comparison is interesting, @GuateGojira. Remember the size difference between Amur's head length and skull length, @peter ? Amur's head length is longer than its skull length because as you can see, Amur's nose is too elongated for a typical Amur tiger. I guess the same for the other Prague male Amur, its name is Benjamin if memories serve me right. So, guessing from the picture, the bigger Amur which is from Duisburg Zoo could have skull length between 45-48 cm because it have no exaggerated facial features like the Prague Amur. The Korean Zoo Amur tiger, Bengari, could have a bigger skull though. 
@tigerluver
@"Khan85" Do you guys know where I can find that report of an amur tigress that attacked a wolf pack and potentially killed one or more? I'm sure there was a report similar to this on this or another thread but I can't find that anymore, I'm sure there was also a night vision cameratrap showing the tiger doing that.

A juvenile Amur tigress named 'Ilona' drove an entire pack of wolves out of a reserve and killed at least 4 wolves in the process. "Tigress Ilona continues to exterminate wolves. A few days ago, when examining her cluster, the remains of another wolf, killed and eaten by her, were found," continues the deputy director for scientific work of the Khingansky Reserve. "From mid-November to the present day, her menu consists of two wapiti, two wolves, ten deer and 20 piglets." "With the arrival of Ilona, the number of wolves has decreased, they have moved to a more safe territory for them, that is, away from the tigress." https://ampravda.ru/2015/05/23/057616.html “The remains of an adult wolf killed and eaten by tigress Ilona were found in the Khingansky Nature Reserve. According to Vyacheslav Kastrikin, Deputy Director of the Khingansky Nature Reserve, this is the fourth reliable case in a year when the wild cat has killed a wolf. However, there may be more."  *This image is copyright of its original author "Hunting tigers for wolves is an infrequent phenomenon. Usually wolves try to leave the territory where tigers live. Therefore, four reliable facts of hunting wolves are an extraordinary case. “No wolf hunter can provide such efficiency,” Vyacheslav said. https://www.amur.info/news/2015/07/26/97335 "The tigress Ilona settled in the Khingansky reserve, displacing other predators - wolves. The flock moved north of the wild cat's habitat." https://portamur.ru/news/detail/putinska...ka-volkov/ |
