Mallards on Upper Las Virgenes Creek

Mallards on Upper Las Virgenes Creek

This rain season has been another dry one in Southern California with many areas recording about one-third to one-half of the normal amount of rainfall.

I have not seen upper Las Virgenes Creek actually flowing any time this rain season. All the creek crossings in Upper Las Virgenes Canyon north of the Cheeseboro connector have been dry to damp all Winter.

Water is pooled in places along the creek, and one of the larger pools is at the creek crossing south of the Cheeseboro connector. I had to laugh when I ran down the hill and saw this pair of Mallards enjoying the pool.

Reagan Ranch Bobcat

Bobcat at Reagan Ranch, Malibu Creek State Park

My rambling New Year’s run at Malibu Creek State Park had begun on the Cistern Trail. I thought I might run to the base of the Bulldog climb and then back on Crags Road to the main parking area. From there maybe I’d do the Phantom Trail loop or run over to Tapia Park and then back to the Lookout Trail.

The route really didn’t matter. It was a classic Southern California Winter afternoon — cool, but not cold, with a mix of clouds and sun. Grasslands were green with December’s rain, and the low sun cast a golden hue over the rocks, oaks and chaparral.

I was running west on the Yearling Trail on the Reagan Ranch property when I spotted a blocky form sitting in a shadow at the edge of a field. About 100 yards away, its profile was accentuated by a backdrop of bright green. Too small to be a mountain lion, too large to be a domestic cat, the wrong shape and behavior to be a coyote, it had to be a bobcat.

Bobcats can be very bold. Last year while warming up for a race at Crystal Cove State Park, I rounded a corner and 50 yards away a bobcat was sauntering down the road. I continued at an easy jog up the road and the bobcat continued walking down the road toward me.  I expected it to dart into the bushes, but it just kept walking toward me.

When we were about 20 feet apart, it casually stepped to the edge of the road, near some brush. I slowly approached and then stopped. The cat was five short feet away, with her back to me and head turned toward me. I was astonished to be so close, but a little unnerved by the animals brazen behavior. After what seemed like minutes, but was probably only 10-15 seconds, we both continued on our way.

The Reagan Ranch bobcat wasn’t nearly as cooperative. I snapped a couple of photos at max zoom (about 90mm) and then as I took a couple of steps in the cat’s direction it loped up the hill and into the oaks.

Mountain Lion Saga

 

Mountain lion tracks at Sage Ranch Park in the Santa Susana Mountains, near Los Angeles.
Mountain lion tracks at Sage Ranch Park

Nature isn’t necessarily nice. Behavior and interactions among animals are often violent. So it is with mountain lions. But the mountain lions of the Santa Monica Mountains also have to cope with the additional problems of living on an island of lion habitat in the middle of an ocean of urban sprawl.

The mountain lion tracks above were photographed on a run at Sage Ranch Park in late January 2000. They might have been made by a young male mountain lion designated P3, whose territory encompassed this area. There is also a possibility there were from an older female lion, P4 that frequented the Rocky Peak area. Unfortunately, both these animals were killed in late 2004 by eating prey (coyote) that had eaten rodents that had consumed anticoagulant-based poisons. These poisons are used by parks, schools, golf courses, and housing developments for rodent control.

The P3 and P4 pumas were tracked as part of an ongoing study started by the National Park Service in 2002 to learn more about mountain lions in the Santa Monica Mountains National Recreation Area. As of May 2012, twenty-six mountain lions, P1 to P26, have been tracked, and their history has been quite a saga.

The patriarch of the lions in the study is P1. He was the first lion captured and collared in 2002, and at that time was estimated to be 5-6 years old. In his prime, P1 was a large, 140+ lb. male whose territory was essentially all of the Santa Monica Mountains. In August of 2004, P1 and P2 – the only female lion known to be in P1’s range – produced a litter of four cubs — two males (P5 and P8) and two females (P6 and P7).

Despite high hopes for the lions and their new litter, things turned ugly in August of 2005, when P1 killed his mate P2. A few months later, in June of 2006, P1 also killed one of the 22-month-old females from the litter, P7. According to biologists these were not the actions of a lion run amuck but were most likely related to conflicts over kills, or in the case of P2, a mother protecting her offspring.

As might be expected, the young males from the litter, P5 and P8, headed for opposite ends of P1’s territory. However, urbanization and limited linkages essentially prevented their escape to other wildland areas.

In early September 2006, P5 was likely killed by P1, and in a development that surprised researchers, P8 appeared to have been killed by an unknown lion, probably male, inside of P1’s territory. The “unknown lion” was the male P9, who was killed by a vehicle on Las Virgenes road in July 2007.

One other female lion was collared and designated P13. DNA testing indicated that P13 was a daughter of P6. At that time P6 was the only surviving lion from P1 and P2’s 2004 litter.

P1 appears to have been injured in a battle for dominance in March 2009. A bloody radio collar and tufts of hair were found in a tree in Hidden Valley, near Thousand Oaks. P1’s opponent was suspected to be P12, a lion collared in December 2008, and the first lion to be tracked crossing the 101 Freeway. Scat found three weeks after the fight was genotyped, and found to be P1’s.

In May 2010 P13 had a litter of three kittens — P17 (female), P18 (male), and P19 (female). The father was P12. Since P12 originated from an area other than the Santa Monica Mountains, this increased the genetic diversity of the mountain lion population in the study. P18 was killed August 30, 2011, attempting to cross the 405 freeway.

It is unclear how many male lions now inhabit P1’s original territory. P12’s collar is no longer functioning. P18 was killed August 30, 2011, attempting to cross the 405 freeway. P15 was found deceased on September 11, 2011. Reportedly another male lion has been photographed in the area.

In May 2010 a male lion living in the Santa Susana Mountains west of I-5 was collared and given the designation P16. This is the first lion to be followed in the Santa Susana Mountains since P3 and P4 died in 2004, after eating contaminated prey. P21, an adult male, is also being tracked in the Santa Susana Mountains. Both P16 and P21 have made excursions into Angeles National Forest, and P16 remains there.


Mountain lion home ranges

The map above shows the home ranges of mountain lions P10, P12, P13, P14 and P15 in the Santa Monica Mountains, and some monitored locations of P16 in the Santa Susana Mountains. Here is another map that shows the home ranges of the mountain lions P1 to P12 in the Santa Monica Mountains, Simi Hills, and Santa Susana Mountains. It was adapted for the web from this NPS map (PDF), produced in 2009.

The Puma Profiles page of the SMMNRA website lists the mountain lions that have been studied. More information, news releases, maps, and photos can be found on the main NPS Lions in the Santa Monica Mountains? page.

Johanna Turner of CougarMagic.com has captured breathtaking stills and videos of the area’s mountain lions and other wildlife.

Following are some previous updates to this post, with links to additional articles and information.

Update October 24, 2012. The remains of P-25, an approximately one-year-old female mountain lion were discovered by hikers in Point Mugu State Park on Sunday. P-25 and P-26 (male) are the offspring of P-12 (male) and P-13. The death did not appear to be the result of a conflict with another lion. A necropsy is pending.

Update October 18, 2012. This summer NPS biologists discovered two mountain lion kittens, P-23 (female) & P-24 (male), east of Circle X Ranch in the Santa Monica Mountains. They are the offspring of P-12 (male) and P-19, a daughter of P-12. The kittens were outfitted with tracking devices.

Update June 18, 2012. Analysis of the DNA of the mountain lion killed by authorities in downtown Santa Monica on May 22 revealed it is related to lions that reside north of the 101 Freeway. One possibility is that the approximately three-year-old lion was the offspring of mountain lion P-12. P-12 has been documented crossing the 101 Freeway in Agoura and is the only lion known to have done so.

Update May 26, 2012. Earlier this Spring biologists from Santa Monica Mountains National Recreation Area (SMMNRA) captured an adult male mountain lion in the Griffith Park area. Designated P-22, the approximately three-year-old lion is the first to have been photographed east of Cahuenga Pass and within the Santa Monica Mountains eco-region. The lion was fitted with a GPS collar and released where it was captured. According to Kate Kuykendall, Public Affairs Officer for the SMMNRA, preliminary genetic analysis by UCLA indicates that P22 is likely from the Santa Monica Mountains, which would mean he crossed both the 405 and the 101 Freeways.

Update November 21, 2011. On October 4, 2011, the National Park Service announced that male mountain lion P-15 has been killed. It was the first documented intentional human-caused death of a mountain lion in the Santa Monica Mountains. P-15’s collar stopped transmitting on August 25, 2011. P-15 was discovered on September 11, 2011, following a report of a dead mountain lion. The California Department of Fish and Game and the National Park Service are seeking information related to the death of P-15 and the parties responsible. With the addition of $5000 from the City of Malibu, the reward being offered for information leading to the arrest and conviction of the poachers currently stands at $16,700. The DFG Cal Tip Hotline is 1-888-334-2258.

Update August 7, 2009. According to Where the Mountain Lions Live in the Santa Monica Mountains in laist.com, P1 may have survived the fight with another mountain lion back in March. DNA from scat collected about two weeks after the fight matched P1!

Update March 28, 2009. There was sad news earlier this month. According to an article in the Daily News, mountain lion P1, the long-standing patriarch of the Santa Monica Mountains, appears to have lost a battle for dominance with another mountain lion. A bloody radio collar and tufts of hair were found in a tree in Hidden Valley, near Thousand Oaks. P1’s opponent is suspected to have been P12, a lion collared in December, and the first lion to be tracked crossing the 101 Freeway.

Update October 6, 2008. The Ventura County Star reported that a young male lion was found dead on October 2 on the 118 freeway, just west of Rocky Peak Road. A wildlife passageway crosses under the freeway nearby and has been used by at least one other lion. On July 18 a mountain lion was reported in the area of the Chumash Trail.

Update May 1, 2008. NPS wildlife biologists are currently aware of 4 lions in the Santa Monica Mountains — 2 recently radio-collared young males designated P10 and P11, and P1 and P6. There is probably at least one more female, the mother of P10 and P11. A remote camera picture has also been taken of a lion in the Simi Hills.

Update January 25, 2008. An article in the Simi Valley Acorn reported that on January 13, 2008, a mountain lion was discovered in an abandoned building near Chatsworth Reservoir. Two days later there was another mountain lion sighting in the nearby Simi Hills by employees at the Santa Susana Field Laboratory.

Update August 7, 2007. According to an article in the Malibu Times, on July 31 a five or six-year-old mountain lion was hit by a car near the tunnel on Malibu Canyon Road and died shortly thereafter. The mountain lion, designated P9, was recently collared, and along with P1 and P6 was one of three mountain lions being tracked by the NPS. There is speculation that P9 may have been the unknown lion that killed P8.

Feather Along the Secret Trail

Semiplume feather along the Secret Trail in Calabasas, California.

This intricate feather was caught on a bristly stalk along the Secret Trail (Calabasas – Cold Creek Trail). The slightest breath of wind would jostle its branches and branchlets. I found I was holding my breath, waiting for the still moments when I could take a photograph. The feather is smaller than the photograph suggests, perhaps 1.50″-1.75″ in length.

There are several types of bird feathers, the most familiar of which is probably the contour feather. The Feather on the Modelo Trail is a contour feather. In a sense contour feathers form the outer shell of a bird, defining its form and coloration. Wing and tail feathers are contour feathers. The fluffy feather with a familiar name — the down feather — provides insulation.



The feather found along the Secret Trail is a semiplume feather. A semiplume feather looks like it is a blend of a contour feather and a down feather, and has some of the characteristics of both. Like a contour feather it has a supportive shaft, but like a down feather it has filamentary branches (barbs) and branchlets (barbules). This combination helps to fill out the bird’s shape, and also provides additional insulation.

The barbules of contour feathers have hooks (barbicels) which join adjacent barbs to form the blade-like vanes of the feather. The barbules of semiplume and down feathers do not have hooks. This allows the barbs of the feather to spread in three dimensions and more easily fill a space. Here’s a closer view of the barbs and barbules of the Secret Trail feather.

To see how the Secret Trail feather compares to other semiplume feathers, I asked long-time climbing, kayaking, and running partner Gary Gunder — now living the good life on the North Shore — if he could take some photos of feathers from some of the birds at Tin Roof Ranch. Courtesy of Gary, here are photos of semiplume feathers from a chicken, turkey, and goose.

For more about feathers and birds see Feather Structure on the Cornell Lab of Ornithology All About Birds web site.

P.S. I asked Gary how his running is going, and he replied, “I run every day… across the Kamehameha highway to go surfing!”

Coyote Tag

coyote that ran with me

I was deep in thought, but have no idea what those thoughts might have been. It was at that point in a run when miles, and thoughts, flow freely. The afternoon was warm and calm and the settling sun cast a golden hue on the blond, oak-studded hills. My footfalls ticked out a steady rhythm on the dirt road, and my mind was at ease.

My reverie was suddenly broken by the realization that a coyote was running with me. Not running yards in the distance, or in the brush off to the side, but five or six feet in front of me, as if restrained by an invisible lead!

It must have come from the tall grass along the margin of the road, but from my daydream-warped perspective had just suddenly appeared. I’m surprised I didn’t stumble or start. But there was no hint of aggression or malice — just a mischievous glance backward to see how I was going to react.

I didn’t. I’ve had numerous encounters with coyotes, but this went so far beyond my other experiences, I didn’t know how to react.

For more than 50 yards the coyote ran with me, keeping pace in lead along the deserted dirt road.

At some point I started to try and retrieve my camera from the small pack on my waist. The out of synch movement disturbed the delicate balance of this improbable scene, and I could see the change in the animal’s demeanor.

Before disappearing into the cover, the coyote looked back a final time, and in so many words seemed to be saying “gotcha, you’re it!”

(From a run Tuesday at Ahmanson Ranch, now Upper Las Virgenes Canyon Open Space Preserve.)
