Kintoo Dhawan: " Yellow-throated Marten ! These cute Predators are very ferocious, they can even kill small deers and monkeys ! "
Lucien Beaumont: " One of Africa’s most seldom seen small predators, the African Striped weasel, making an escape to freedom after I rescued it from underneath a house this morning. "
Because of the spread of the coronavirus, Denmark had decided to cull all its captive mink (I assume the European or Eurasian species, Mustrela lutreola), which numbered around 17 million, before that raised an outcry: https://www.who.int/csr/don/06-november-...enmark/en/, https://www.bbc.com/news/world-europe-54890229, https://www.sciencemag.org/news/2020/11/...s-research,

Here's a published skull with "echinochrome staining" from Winer et al. 2013, who reported that 25% of Enhydra lutris specimens had such staining - and 2/3 of which are males. This staining apparently comes from eating urchins.

Low individual diet variation and high trophic niche overlap between native polecat and invasive American mink
Abstract Introductions of invasive species increase competitive interactions in a community proportionally to the similarity between the ecological niches of invasive and native species. Food represents one of the most important resources in uencing competi- tion, and differences in the trophic niche of native and invasive species can affect their ability to coexist. Moreover, in sympatric native and invasive species of simi- lar body size and high sexual dimorphism, competition for food between individu- als of the same sex may be higher than intraspecic competition between males and females, thus making the overall competitive interactions more complex. The aim of this study was to investigate the intraspecic and intrasexual competition for food resources between two sexually dimorphic mustelids, the native polecat Mustela putorius and invasive American mink Neovison vison, in riparian habitats of Białowie _ za Forest (Poland). Based on an analysis of 1215 scats, we studied the food habits of eight polecat and 24 mink individuals. The trophic niches of the polecat and mink were narrow and overlapped considerably. The diet of both predators was dominated by amphibians (mainly the common frog Rana tempo- raria), which comprised up to 94.1% and 89.7% of polecat and mink prey bio- mass, respectively. Individual diet variation was low within each sex group of both species. Interspecic similarities in body mass of the sexes and intraspecic differ- ences in body mass between the sexes did not affect pairwise niche overlaps. How- ever, we observed some mechanisms of food segregation between the sexes and species that reduced intra- and interspecies competition. Polecat males hunted more common toads Bufo bufo than polecat females, mink males and mink females. They also hunted larger frogs than polecat females, and the opposite pattern was recorded in mink. We conclude that two predator species exploiting abundant prey can coexist despite a very high overlap in their food niches.

Distribution of the Yellow-throated Marten in Bangladesh
From 'Sighting of a Yellow-Throated Marten Martes flavigula in Human Dominated Landscape of Northeastern Bangladesh' LINK "The species is thought to occur in mixed evergreen forests of northeastern and southeastern Bangladesh (Chutipong et al. 2016). There are confirmed records only in Greater Sylhet division of northeast Bangladesh (IUCN Bangladesh 2015). In northeastern Bangladesh, it is found in less than 10 locations, occupying an area of 505 sq. km (IUCN Bangladesh 2015). There is no quantitative data on the total population of the species in Bangladesh. The species is threatened by ongoing degradation of habitat quality due to overexploitation of resources and expansion of betel leaf cultivation, therefore, the species has been categorized as Vulnerable in Bangladesh (IUCN Bangladesh 2015). Here we have documented the yellow-throated marten in human dominated area adjacent to Lawachra National Park (LNP)." "We encountered a yellow-throated marten in HEED Bangladesh guest house (24° 20′ 20.9″ N, 091° 49′ 25.3″ E) located in Kamalganj Upazila, Maulvibazar district in the northeastern region of the country." "As yellow-throated marten has recently been discovered in Bangladesh, no quantitative data is available on its population status and ecology in Bangladesh. It was not assessed by IUCN in 2000 in Bangladesh (IUCN Bangladesh 2015). The species has been categorized as Vulnerable in Bangladesh (IUCN Bangladesh 2015) due to habitat destruction and population degradation. Globally, the total number of individuals is declining (Chutipong et al. 2016). So proper research and documentation of incidental records and studies on population status, ecology, and threats are needed, which would greatly improve our understanding of the species’ distribution, ecology, and conservation status in Bangladesh."  *This image is copyright of its original author The IUCN Red List Assessment of Yellow-throated Marten (Martes flavigula) LINK Yellow-throated Marten occurs in South, South-east and East Asia, from Afghanistan and Pakistan in the west, along the Himalaya and foothills east to southern China, throughout mainland South-east Asia, and the islands of Sumatra, Java and Borneo, It also extends north through eastern China (including Taiwan) and Korea to the Russian Far East (Corbet and Hill 1992, Matyushkin 1993; Wang and Xie 2004, Stevens et al. 2011, Kerley and Borisenko 2014). There is one old specimen labelled 'Singapore' (Meiri 2005), but no other suggestion of occurrence there (M.A.H. Chua pers. comm. 2014). In Bangladesh it occurs in the North-east and South-east (Hasan Rahman pers. comm. 2014). Statements of occurrence in southern India refer to the taxon gwatkinsii, here considered a full species, but widely treated as a race of Yellow-throated Marten until recently. Country Occurrence: Native: Afghanistan; Bangladesh; Bhutan; Brunei Darussalam; Cambodia; China; India; Indonesia (Jawa, Kalimantan, Sumatera); Korea, Democratic People's Republic of; Korea, Republic of; Lao People's Democratic Republic; Malaysia (Peninsular Malaysia, Sabah, Sarawak); Myanmar; Nepal; Pakistan; Russian Federation; Taiwan, Province of China; Thailand; Viet Nam  *This image is copyright of its original author Camera trap images of yellow-throated martens in Bangladesh. Northeast Carnivore Conservation Initiative (led by Muntasir Akash of Jahangirnagar University): "Here is a trap-snap of 2 individuals of Yellow-throated Marten (Martes flavigula), which itself is a rare capture. The species is restricted to the mixed evergreen forest areas in the northeast (Greater Sylhet) of Bangladesh. The quality of habitat is degrading due to overexploitation of resources and expansion of betel leaf cultivation. Therefore, the species has been categorized as regionally Vulnerable. This species is usually active during day, but rarely at night. Occurs solitary or in pairs. Very agile and can move quickly on ground and in tree canopy making it difficult to capture photos."  *This image is copyright of its original author More camera trap images  *This image is copyright of its original author  *This image is copyright of its original author Key information derived from this post on Yellow-throated Martens:
