|During the pandemic, I lived near Sunset Junction and would go on
|walks at night and had to listen for packs of coyotes howling on
|certain streets so as to avoid them. Never saw more than 4 at one
|time, though, but the coyotes seemed to be kind of enjoying that
|time period, though the trash near the restaurants being empty was
|likely also an issue for them, hence the moving deep into
|neighborhoods.

|Growing up in the desert if you see them you’re gonna see them
|during the day. They come into fields during the day looking for
|food. They howl to each other early in the morning and late at night
|to let each other know where they are/have been sleeping and the
|will link up at dawn and dusk occasionally. But I live in a huge
|city now that does have coyotes and in the streets I’ve only seen
|them at night.

|Right? As long as I’ve ever lived, they have been. My parents live
|in an extremely rural area, and the coyotes are nocturnal there as
|well. I guess they just prefer the night in those locations with
|almost no humans.

|This is true in Bay Area, where I am. I've seen at least one mountain
|lion running in the streets in Novato in the middle of the night, and
|you can hear the coyotes howling on a semi regular basis after the sun
|goes down. The coyotes make themselves known, but the mountain
|lion, I was surprised at, I had no clue until it ran past my car.

|I’ve linked to the news release in the post above. In this comment, for
|those interested, here’s the link to the peer reviewed journal article:
|Human recreation influences activity of a large carnivore in an urban
|landscape
|https://www.sciencedirect.com/science/article/pii/S0006320724003744
|Abstract Human recreation influences the diel activity of animals and
|elucidating these responses informs management of species of
|conservation concern. We studied how mountain lions (Puma concolor)
|persisting in greater Los Angeles, California, USA adjust diel activity
|patterns in response to spatial and temporal variation in human
|recreation by combining publicly available data on recreation with GPS
|telemetry and accelerometer data. Mountain lions reduced diurnal
|activity, shifted timing of dawn activity, and became more nocturnal in
|areas with high recreation. There were differences in temporal responses
|between the sexes that might reflect behavioral shifts by females to
|avoid potentially dangerous male conspecifics. We found no evidence that
|mountain lions modified their behavior based on differences in
|recreation between weekdays and the weekend. The lack of a weekend
|effect may be a function of mountain lions being mostly nocturnal, which
|may be sufficient to avoid most recreation regardless of intraweek
|variation. Mountain lions have persisted within greater Los Angeles
|despite being limited spatially in this human-dominated landscape. Our
|work suggests that mountain lions are also constrained temporally
|through shifts in their diel activity. From the linked article:
|California’s Mountain Lions Are Becoming Nocturnal to Avoid Human
|Activity Mountain lions in greater Los Angeles are proactively shifting
|their activity to avoid interacting with cyclists, hikers, joggers and
|other recreationists, finds a study from the University of California,
|Davis, Cal Poly Pomona and the National Park Service. The study,
|published Nov. 15 in the journal Biological Conservation, found that
|mountain lions living in areas with higher levels of human recreation
|were more nocturnal than lions in more remote regions who were more
|active at dawn and dusk. The authors said their findings offer a hopeful
|example of human-wildlife coexistence amid a large, dense human
|population. Still, the authors note, this doesn’t mean mountain lions
|should do all the work. People can help protect themselves and mountain
|lions by being aware that dawn or dusk is prime time for mountain lion
|activity. They can also be extra cautious when driving at night, when
|mountain lions in populated areas are more likely to be active.

|I don’t think proactive means what that author thinks it means.
|u/cakeandale - 9 hours
|
|It can, it depends on framing. If I know traffic will be bad tomorrow
|leaving early can be proactive way to avoid traffic. The traffic is a
|recurring problem I am being reactive to, but my change in behavior is
|also me being proactive towards a future incident of it.
|u/domuseid - 7 hours

|I think he means if they'd done it proactively we wouldn't be
|noticing a change because we'd always have known them to be
|nocturnal
|u/cakeandale - 6 hours
|
|That’s the framing part - they’re being reactive to human trends,
|but acting proactively towards future incidents of those trends by
|adjusting their schedule. Kind of like proactively leaving early
|to avoid traffic you know will be there.

|California is lucky to have these big cats around. Great for the
|environment. There are some 4,500 mountain lions in the state. One of
|the best things is how disinclined mountain lions are to attack people.
|[Not like African lions](https://www.nature.com/articles/436927a), which
|in a 15-year period in Tanzania starting in 1990 "killed more than 563
|Tanzanians...and injured 308."
|u/Hiraethum - 10 hours

|This is great. I really want predators to come back (in a well-managed
|and safe way), but interactions with humans can lead to lethal
|repercussions for them. I'm glad they're adapting. I wonder how much of
|it is driven by prey cycles as well. I know boars have been switching to
|nocturnal to avoid humans for instance.
|u/707breezy - 7 hours

|I say we shouldn’t half ass it when it comes to slow and steady
|release of predators. We should full ass it and bring back a whole
|herd of grizzly bears into California. Find a cousin of the grizzly,
|and modify it to match the grizzly and maybe add in some variation to
|give it a running start on all the predator-ing it missed. As a
|Californian I’m tired of running and exercising at night in my area
|with little to no fear of the darkness and unknown. My female friend
|said she has fear of doing work outs alone at night but I think
|that’s for other types of predators.

|They built this nice paved biking/running trail between two new
|subdivisions in the foothills near Valley Springs, Ca. This woman went
|out jogging one morning and disappeared. Search and rescue found her
|partially eaten body in a den just a few hundred yards from the trail.
|There was a mother and two cubs. There are deer around, but they run
|faster then people. Mountain lions are opportunistic hunters.
|u/dxrey65 - 8 hours

|That's still very rare. I think there have been something like 28
|fatal attacks in 130 years in the US. Of course there's still good
|reason to be careful; there are mountain lions in my area and if one
|is seen on a hiking trail or something they put warnings up. I
|generally avoid going out close to dawn or dusk. I've never seen a
|lion, but I see their tracks all the time in winter when there's a
|fresh snow.

|When I lived near the aptly named Los Gatos back in the late 1990s, a

|Interesting. I have been stalked by a mountain lion and had one steal a
|deer I hunted. Both times in the daylight. I am in the Black Hills
|though, so a totally different population of mountain lions. Also got
|followed/hounded/harassed by a pack of coyotes at dusk here once. They
|followed me making all kinds of noise for about a mile back to my truck.
|That was scary, but the mountain lion stalking me was scarier. I don’t
|go out hunting in the hills without a sidearm anymore.

|Proactive means making changes or plans before something happens.
|Reactive is a response to events after they occur. I don't the lions
|got together to make this change. They are reacting to their
