You can see in this photo a great example of the understep walk that these awesome little creatures move in, with the five-digit rear feet landing just behind the four-digit front feet. So cool to see them walk. Note also the tail drag in the middle.


2016 Jan 17 – a quick Arizona experience

I found myself briefly in Arizona this weekend, and despite it not being a planned “adventure,” of course I’m always tracking. Got some new tracks I’d never seen before.

I was in an area that is renowned as a birding hot spot, and it’s also not far from where there have been jaguar sightings. That’s right, JAGUAR. This place in southern Arizona in the Santa Rita mountains is an interesting ecology, high desert, and home to some of the only perennial creeks in these deserts. The Santa Rita mountains are in the shadows of Mount Wrightson.We broke out for a short hike in the Patagonia-Sonoita Creek Preserve, and though we didn’t see a lot of wildlife (it was midday), we spotted some nice tracks.

We stumbled on some mysterious feed sign, it looked like broccoli barfed up in the middle of the trail. As we considered all possible solutions, including vegetarian humans that might have puked on the trail after a rough night at the Wagon Wheel, we finally came upon a solution …

I determined that likely it was wood rats (tracks below) and also possibly squirrels that were opening up the fruits and leaving the broccoli-like remnant behind …

Beautiful country, I can’t wait to return.

chasing mountain lions blog to resume soon …

I’m excited to report that I am helping with a new puma project in the Bay Area, my other blog chasing mountain lions will be updated with a new chapter soon …

Here are pictures of tracks of two of the cats that we are tracking and trying to capture right now in the mountains East of San Jose near Mount Hamilton:

trailin’ hogs!

I had the good fortune to go for an adventure yesterday with a friend to practice trailing animals – the species of focus was the feral pig (feral hog).

The weather was outstanding, despite some strong winds early in the day. It doesn’t get much nicer here than these sunny days with clear blue skies and temps in the 70’s – and the light was great too. I knew it was going to be a good day when not long after sunrise I saw a juvenile bald eagle (hatch year / 1st year) perched in a tree overlooking a creek. It was eyeing up some water fowl and steelhead, the latter of which were spawning in the creek bed below.

Steelhead are a type of salmon, and once were found in great numbers up and down the west coast. As with many of the salmon, their populations have been suffering due to over-fishing, habitat loss, and pollution. This time of year, mature fish swim from the ocean back into small creeks and streams from where they were born, where they create nests in the creek beds to lay their eggs. Unlike other salmon who die after spawing, some steelhead return to the ocean for another go. Interestingly, according to current science taxonomy, they are the same species as rainbow trout – the difference being that steelhead are anadromous, meaning they spend part of their life in the ocean. Because of this, they look physically different than fresh water rainbow trout (larger). These fish shown below were probably close to three feet long!

I was on my way to a remote area of western Sonoma County where we were going to do our wander, on some land miles from any roads by the Gualala River. I feel like Sonoma County is my “second childhood home” – and it felt so good to be visiting on this beautiful spring day.

When driving along a ridge line with views going miles in all directions, the land looks like a piece of bunched up fabric – deep, drastic valleys at the bottom of steep descents that fall from high mountain tops and ridge lines. Huge stands of douglas fir and redwood are on many of the north-facing slopes, with oak woodland spanning other parts of the more sunny areas. Some of the land remains ranch land, and many folks have made their living with sheep and cattle out here. “As the crow flies,” the distance between two points seems not too far – but when traveling on land, it can take a long time to travel a short distance. And there’s seldom a direct route. Perhaps it is this ruggedness that has helped keep it somewhat intact – it isn’t conducive to the industries of man. May it remain as such!*

Feral pigs, also called feral hogs, are non-native animals whose relatives escaped from the domestic life and have secured a place for themselves and their progeny in the wild. Sonoma County has a large population of them, and many areas of the country consider them to be a pest. They certainly don’t tread lightly on a landscape – in areas of high density, the ground can be torn up all over the place from their rooting. They are an amazing animal – highly intelligent, very social, and incredibly adaptable. They can also get pretty big – some of the larger boars are around 300 pounds! And they can be pretty intimidating to see – large tusks, coarse hair covering parts of their body – they often don’t look like their barn-yard cousins.

I have mixed feelings about the native / non-native debate. The truth is that many of our ecosystems are so different than they were prior to European colonization – especially with the removal of so many of the apex predators – that it is unlikely they will ever be the same. Especially without reintroduction of the trees, plants and animals that were originally here and created a balanced web of life. You don’t grow old-growth redwood trees overnight. I imagine the pigs would not be as successful if there were wolves and grizzly bears around (as there once were in this area) – but I bet the main detractors of the hogs would be even less apt to welcome that strategy!

There is a difference for humans, psychologically, when labeling an animal as a pest and/or a non-native – somehow it’s life seems to be valued less. I have an issue with this. These are still living, breathing creatures, just doing what we all are doing here – trying to make a living. I’m not suggesting that all non-native animals should just run amok with no management plan in place, but I do believe there can be better, more compassionate management strategies that are also more supported by science. Ones that honor these animals as individual living beings, with a value the same as any other living being. Sadly, humans have used (and continue to use) this type of labeling to denigrate people too – whole cultures, races, and people of varying lifestyles have been subjected to horrible treatment because of this manipulative psychology of labeling.

It was fun to get to be in the world of the hogs for the morning! We started off by looking for some fresh tracks so that we could have a chance at being able to trail and find the animal that laid them. The pig sign was everywhere – the trick was finding something fresh. Despite some of the recent rains, the ground in some areas was already becoming quite dry again, so it wasn’t holding sign as well as it had been just a week ago.

IMG_1241

[some fairly fresh hog tracks]

We ended up on several different hog trails, the first of which took us down a steep hill side, traversing downward through the trees. We saw quite a few pig beds – all empty – strategically situated at the base of large trees on a steep slope, with crunchy leaves all around that would belie the presence of an approaching predator (or tracker!) and allow for multiple escape routes. After being on it for quite a distance, eventually we lost the trail – which seemed impossible, given we were following a number of individuals travelling together. How do 150 to 300 pound animals seem to vanish and leave no discernible sign? Perhaps there is a “pig vortex,” similar to the “raptor vortex” – the place raptors seem to often disappear to, out of the air, when you take your eye off them for a second! Amazing! Humbling.

We continued on, looking for another trail to follow, and eventually we found some more fresh sign just off the dirt access road we were following. After poking around a bit, we took a hog trail down another steep slope descending 100’s of vertical feet. There were some fairly fresh tracks on it, but mostly we were just curious where they were going as it seemed to be a highly used trail. It took us all the way down to the bottom of the valley – and to the Gualala River.

IMG_1249

I could have spent days at that spot. The river was gently flowing past, its gray-green waters moving over small round river stones on its bed. Small waterfalls and seeps were cascading into the river from the steep hillsides, scouring the rocks and making a home for glowing moss and lichens. An abundance of life, and signs of animals passing through, was everywhere. I was overwhelmed by the calm and beauty.

I finally couldn’t resist and waded into the water (it was also the easier route around some poison oak that was guarding a narrow pass on the steep banks!), and saw a couple of newts hanging out under the surface of the chilly water …

Once I made my way back to shore, we saw a little snake sunning itself on a rock ledge. All the animals seemed to be in the same blissful, relaxed state that I was in … under the spell of the Gualala River and the warm sun above.

Finally, we hit upon some nice fresh hog tracks in the soft sediment on the banks of the river. Back on it!

IMG_1250

These were likely from a pretty big boar. We followed him back up the hillside from where we came, but once again after a little while we lost the trail. Humbling! As we fanned out and attempted to pick it back up again, we found another little creature on the hillside under a log that we had disturbed.

As we got to the top of the hill, we found the boar tracks again … and it was one of the tracks that we had originally seen when we started on this trail! We had come full circle.

IMG_1263

We reluctantly made our way out of the property, but as we were leaving we spotted one last treat – a golden eagle! it was a double eagle day. A good sign and a perfect ending to a great morning.

I am so thankful to have gotten to spend the day out there, many thanks to my friend Matt for taking time to share this special place with me.

* As a side-note, in recent times vineyard owners have been trying to push into some of these areas because they are ideal for certain grape varietals, such as the popular pinot noir. Thankfully there are many organizations, including Native groups, that are spearheading the effort to keep this land intact from groups who want to convert forest to vineyards (or other clear-cutting). The amount of life that is impacted by deforestation is astounding, and humans have already destroyed 96% – NINETY SIX PERCENT – of existing redwood ecosystems since the west was “settled” … and old growth constitutes just a small part of that which remains. Scientists have barely scratched the surface of understanding ecology and the web of life on this planet, and it has been shown that the canopies of redwood forests contain a huge amount of biodiversity. Seems like there is a lot of value in honoring these remaining places – and perhaps a duty to do so.

Sunday was a warm and clear day on the coast, strange weather for January – it felt like summer (well, summer anywhere besides the coast and the Bay area). We started the day by witnessing some interesting behavior by a couple of deer that caught our attention. The deer, which appeared to be doe and a yearling (nearly the same size), were standing with heads raised and their focus on something in the chaparral to the north of us. The yearling took off trotting, then bounding, right towards the path we were on, seemingly unconcerned with our presence. It then stopped and turned around, bounding back to its mother. The two of them then started a slow walk in the direction of the threat, with the mother in the lead. Shifting our position back down the trail, we were able to see what was causing the concern …

I was only able to catch the tail-end of the bobcat as he disappeared into a coyote bush (for the moment now a bobcat bush) – a large male that uses this particular territory who’ve we’ve tracked and seen around here before. Although I think it’s rare for bobcats to take down full grown deer in this area, fawns are fair game. This particular young one is probably big enough to be safe, but given the respect that the deer on this day showed towards him, and on another occasion when I witnessed his presence disturb them, I’d say he is still viewed as a threat. He seems to be a large bobcat based on his tracks and scat.

The most interesting part of this whole interaction was when the deer started to FOLLOW the bobcat – the doe literally walked right to where the cat had disappeared, and she seemed to be chasing HIM out of the area! Good stuff.

On the way in to the lagoons, I spotted an American bittern in a small pond along the pathway – I’ve seen one on the far shores of the larger lagoon, but never one so out in the open here. It was shaping up to be another good day, with lots of live animal sightings. Later in the day on the return trip it was still there and posed for some pictures in the beautiful light.

As we approached the lagoon, a resident great-blue heron was hunting in the shallows.

There were quite a few sets of trails and tracks on the dunes, but the striped skunks were most prevalent. This is their mating season, during which they really seem to be wandering around outside of their normal areas with higher frequency – sadly it is also marked by the large number of road kill skunks at this time of year. Notably absent was the female bobcat that usually patrols this area. It is also breeding season for the cats, so her daily patterns are likely interrupted by the breeding impulse. I also spotted at least one golden eagle soaring above the hills, only the second time I’ve seen one in this particular area. Along with a ferruginous hawk sighting (a somewhat rare winter visitor in this area) and the great view of an intermediate morph red-tailed hawk, we had some great raptor and other bird sightings. During the day at various times the family of otters was visible on the upper lagoon, but I never really was close enough for any pictures. Just their presence is a joy, watching them even from afar is so fun.

As we were resting by the lagoon, a pie-billed grebe made it’s way out of the shallows by the cattails with quite a prize – after straining to identify what it was, we realized it was a small bass! The grebe paddled around with the fish in its beak for at least five minutes, occasionally shaking it and twice losing it in the water, but diving down and quickly recapturing it. Finally, after almost ten minutes, it downed the fish whole!!

Impressive.

Another great day out there, I’m so thankful for that place and to be able to wander in it. Thanks also to Richard Vacha and everyone who participated in this Marin Tracking Club excursion for making it a fun and educational day.


teaser

There are too many photos and stories from yesterday to rush this tale, which I don’t have time at the moment to honor properly  – but here are a few teaser photos until I do. Honestly, books could be written about what is found in any few square feet of space in places like Abbott’s Lagoon. The richness and density and variety of life in this area, along with many friendly substrates that record so much of it to see afterward, is just such a gift.

The above picture is of a Great-Horned Owl landing spot in sand – you can see where it landed, and in the foreground is the imprint of its wing feathers in the sand. You can also see the trail of it walking away, out of the frame to the top left of the picture … a trail of about 15 feet, where it took to the air again.

Both tracks look like front left for each animal, which is pretty cool. Amazing detail in the fox track, you can see the hair impressions in the mud silt – also, it’s not often that the claws register (gray foxes have semi-retractable claws and are able to climb trees).
