Wolf pups recorded on audio in Denmark
Wolf enthusiasts who track the wolves in Denmark say they have recorded audio of wolf pups in the central and western of Jutland (Denmark). They recorded a howl on audio, in which they believe, wolf pups can be heard. The guy who recorded the howls says that the puppies’ howl has the same sound and tone as that of adults, but are lighter, shorter and not as strong. The trackers also spoke with witnesses who claim to have seen wolf pups.
They do not want to tell where exactly they heard the howling, to prevent the wolves from being hunted.
Wolf expert Thomas Secher, who is senior scientist at the Natural History Museum, said that so far no DNA traces have been found, but it is not unlikely that there are wolves they have not yet on track.
