How wolves travel in a five-part formation where every position serves a purpose, from the weakest at the front to just a single wolf at the back. [🎞️ thebrainmaze]

This video gives a rare glimpse into the "fishy" proclivities of wolves in our area. The video was taken in spring just a short distance from a creek wolves have fished at for many years. This past spring was the 10th year we have documented wolves hunting and catching fish—a behavior that had not been documented in boreal systems such as ours until our work, in part, because it is a tough behavior to observe. What is particularly fascinating is that this wolf was not only carrying a fish but carrying two of them. This is interesting because when we captured this behavior on video for the first time in 2018, we observed a wolf fishing, drop them on the creek bank, and wade back in to continue fishing. I.e., the wolf was not immediately consuming the fish it caught but rather fishing while the fishing was hot, and then once the fishing cooled down, would consume the fish. And this video seems to provide some additional evidence that it might be a widespread strategy wolves use. Two other interesting tidbits from this video: 1.) The wolf that dropped the fish was a yearling wolf. The wolf that grabbed the fish at the end was a different wolf. More specifically, the breeding female of the Half-Moon Pack and the older sister of the yearling wolf. 2.) Surprisingly, the black bear seemed very perplexed at finding this fish, and just left it alone without even taking a little nibble. We would have expected a bear to readily take a free meal like this but apparently not. We have collected of detailed information on how, when, where, and why wolves hunt fish in our area. You can read all about that in our scientific article (which is freely-available at the link below!): Freund et al. 2023. The ethology of wolves foraging on freshwater fish in a boreal ecosystem.

CVS in the Bronx. No staff at the front. Yet, five employees in pharmacy at the back (all on their phones). None knew what a notary is. NYC has been abandoned.

For almost 2 years now, this lone wolf has hobbled around the Voyageurs area on 3 legs. The wolf’s front left foot is permanently injured/disabled for some unknown reason. We shared a post about this wolf in 2023 and since the wolf is still around, figured we would just share an update with some footage we captured of this wolf over the past year. When wolves lose the function of a back leg, they can still move around fairly quickly because most of a wolf’s power and balance comes from their front legs where most of their bulk and muscle is. We have seen many wolves on trail cameras over the year that are limping and not putting weight on a back leg that are still moving around pretty well. However, losing the function of a front leg is much more debilitating because wolves cannot move quickly without a front leg. You can see that in this video. Nonetheless, wolves are persistent and resourceful. Clearly, this lone wolf has figured out a way to find enough food to live for several years. From what we can tell, the wolf appears to be in decent body condition too. We can only guess how this wolf would find enough food. We suspect it likely does quite a bit of scavenging (e.g., scavenging other wolves’ kills, roadkill deer, beavers that have been trapped for damming up culverts, and any number of human-created food sources). During summer, this wolf could likely catch hiding fawns and beavers, both of which would not require chasing prey down. However, we do struggle to see how this wolf would kill adult deer or older fawns during the rest of the year since it is hard to imagine the wolf chasing them down.

New video shows a man approaching a pack of wolves in Yellowstone National Park. Keith Allen Kerbs recorded the footage on October 6, saying he was photographing the five black wolves when the man approached them. The video shows the man spraying what he describes as bear spray at the wolves as he enters a ravine. The wolves eventually backed off, and the man walked away. The National Park Service says there have been no reports of wolves attacking humans in Yellowstone and recommends visitors stay at least 100 yards away from wolves.

The American people work at least five days a week. So should we. Congress needs to be at work EVERY SINGLE DAY until we deliver for the American people.
