red-tailed Hawk (intermediate morph)

red-tailed Hawk (intermediate morph)

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.


Point Reyes tracking day

Ahh, where to begin. This post has taken me a long time to get up because one day of tracking can yield volumes of stories and tales!

Our day at Abbott’s Lagoon a few weeks ago began with a morning of warm sunshine, after a few days of very cold temperatures and rain – as we started out towards the sand dunes near the beach we saw quite a few black-tailed mule deer in groups of over ten individuals. There was a herd of males of all different ages in an adjacent field, their antlers varying from sprouts to full racks. They seemed to be frolicking in the warm sun, play sparring and hopping around each other like fawns on a beautiful spring day. What really caught our eyes though was another group of deer to our north … one of them was standing guard to the west and not even our presence took this doe’s attention off something towards the eastern lagoon. Her behavior queued us in to another presence that warranted her attention more than humans. It had to be a predator.

As her group grazed, she seemed to be doing some tracking of her own. We decided to see what it was that garnered such focused attention, and we moved quietly across the chaparral to investigate. As we moved west, the look-out deer finally broke her sentry post and they all moved on to the east. We didn’t see what had attracted her attention, so we started to investigate the area where the deer were grazing to see what was for breakfast. As we moved west through the brush though, our efforts were rewarded as the hard ground gave way to add a character to the story by yielding a single clue … a fresh bobcat track in some soil upturned by a gopher!

We were able to trail it for a distance, the fresh tracks sometimes not visible at all, occasionally popping out for us to see in some loose soil after losing the trail for 20 feet at a time. With great reluctance after trailing the cat for 500 yards, we abandoned our search to see the maker of the tracks to continue on our journey towards the dunes. I would be rewarded later though …

Once at the sand dunes, we saw an explosion of activity that indicated many animals were eager to be out after so many days of cold and/or rain. Another bobcat made some nice trails, along with black-tailed mule deer, river otters, coyotes, gray fox, great-blue herons, ravens, deer mice, beetles, brush rabbits, skunks, opossum, raccoon, and more. There was a lot of skunk sign, and we postulated that they were very active after a short period of torpor (similar to hibernation) that left them hungry and in search of mates. Deer mouse sign was also everywhere, their small tracks making trails all over the dunes.

The evidence of another saga soon played out on the sand dunes before me – a bobcat trail that showed what I determined to be a recently captured brush rabbit. The trail had drag marks that extended under the cat for 30 yards to a spot where it did tight circles as it either made the final kill or adjusted the prey in its jaws, then sat for a bit. The trail went on then for 20 yards up into some dune grasses where there were bits of rabbit fur and presumably the cat ate its meal.

This particular area usually is thick with coyote sign, and seldom have we seen gray fox sign here – but this day showed evidence of at least one fox that had traveled with purpose around the whole area. The tracks are dainty next to the many coyote tracks, and I was excited to see find the trail.

I trailed one of them for half a mile down the beach, its tracks following the vegetation line at the edge of the beach, at one point going down into the surf area where the water washed away its paw prints at the last high tide before it veered back up to continue on its journey north towards Kehoe Beach (where their sign is much more prevalent according to others familiar with the area). It was a very purposeful gait, seldom stopping to investigate the ocean flotsam along the shore. What spurred this fox on an unhurried yet purposeful journey on the beach? The search for a mate? A territorial scouting mission? Food? It will be interesting to see if there is more sign in the future or if the foxes will remain more north towards Kehoe beach after this.

At one point as I backtracked one of the bobcats, I was excited to catch sight of an American bittern hunting in the floating vegetation on the edge of the east lagoon. Among the live animals I saw this day were great-blue herons, ravens, gulls, two snowy plovers (a very endangered species), red-tailed hawks, white-tailed kites, northern harriers, turkey vultures, yellow-rumped warblers, black-tailed mule deer, a peregrine falcon and …

Good stuff.

The dunes are ever-shifting, they can be an amazing palette for animal tracks or the tracks of the wind, giving a brief glimpse at the stories played out in the hours before. But the winds eventually wipe the slate clean like words fading on a page, as the dunes make their own tracks across the landscape.
