When the wolf settles in The Netherlands again, after being absent for over 150 years, how will prey animals such as red deer react? This situation is being simulated in National Park Veluwezoom in The Netherlands, by laying down wolf feces and register the reaction of red deer.
The research is done by capturing the behaviors of the prey animals by trap cameras. In Poland, the same research has been done with the exact same techniques. The research in The Netherlands can show a difference in the result of the research in Poland, because in Poland, wolves have already returned for quite a while.
Here are the first wolf pups in the Cascade Mountains since the 1940s
Remember the “wandering wolf,” OR-7, who traveled from Oregon to California and back while wearing a GPS collar? The US Fish and Wildlife Service discovered that he’s now a proud dad to at least three pups, thanks to some camera trap photo!
The pups are also historic; OR-7 and his mate are the first wolves known to have bred and produced offspring in Oregon’s Cascade Mountains (which stretch from British Columbia to Northern California) since the 1940s! They’re a small, adorable conservation success story.
Pictures: 1: One of OR-7’s cubs 2: One of the pups, who appears to now have a GPS collar of its own 3: Two of the pups 4: Mom, a black wolf (who has not been given a formal designation) 5: And dad, OR-7, in a photo captured in May 2014
Wolves have a pre-caudal scent gland (also called “violet gland”) at the top of their tail, about 10 cm (4 inches) from its base and on the tip. It releases a pheromone, used to mark.
Light colored wolves often have a dark spot of fur covering the scent gland. Below is a picture of a wolf’s tail where you can clearly see this dark spot - I circled it with red. The dark tip at the end of the tail you mentioned isn’t part of the scent gland.
Many domesticated dogs have vestigial pre-caudal glands. In how far these are developmed depends on the specific dog breed. Both wolves and dogs smell each other to locate identifying scents which come from both the anal glandsand pre-caudal glands.
A hidden camera has captured an image of a wolf crossing a wooded clearing in the Czech Republic, a hundred years after the predator disappeared from the area, it’s been reported.
There have been some signs near the town of Doksy suggesting a wolf may be in the region, Radio Prague reports. But wolves haven’t roamed free in Bohemia since the late 19th Century.
There is probably just one wolf or maybe a pair, says environmental expert Miroslav Kutal. The animal is likely to have strayed into Bohemia from the border regions of Germany and Poland, where the wolf population has been thriving.
But Kutal tells Radio Impuls the conditions in Bohemia - especially in former military zones and in the mountainous border regions - seem to be good for breeding. This is something to be encouraged, he adds, since wolves can regulate the deer population and draw tourists to the area. But the arrival of poachers could become a concern.
