Of Birds and Berries

Last weekend we noticed a flurry of bird activity in the backyard.  The perpetrators were a large number of American Robins feasting on a bush which was loaded with red berries. Closer inspection revealed a number of smaller birds – Cedar Waxwings – were also partaking of the feast. There must have been over 50 robins in the area, flying in and out of the bush. You could hear the excitement in their voices as they devoured the berries. The lower photo shows how loaded the bush was. And in a matter of hours all the berries were gone. Several robins were picking up any berries that had fallen to the ground. The berries have been on the bush for a few months but somehow they must have seemed “just right” to the birds at this time.

A Google search leads me to believe that the bush with the red berries is a Pyracantha, though I am not entirely sure. You will be surprised how hard it is to identify a plant with an obvious feature like bright red berries. And plants do not move around or disappear on you.

Snake Sighting in Our Backyard

Sharp-tailed Snake

Sharp-tailed Snake

In early November, I came across an interesting inhabitant of our backyard. It was a Sharp-tailed Snake. We see them every once in a while, usually in summer. This was a small one, lying still under some leaf debris because of the cold weather I suspect. At first I thought it was dead but it had burrowed under the surface by the time I came back in a few minutes.

These small, secretive snakes are seldom seen by most people. I had never seen one until we moved to this house on the outskirts of town in the Tri-Valley area of the East Bay. They are nocturnal and tend to burrow under things – leaf litter, logs, rocks. Their favorite food is slugs. They are reddish in color above and have a striking black-and-white pattern below. The tail ends in a sharp spike which gives them their name.

They are gentle and harmless and should be left alone.

Field Trip to Las Trampas, Contra Costa Co.

Las Trampas Regional Wilderness

Las Trampas Regional Wilderness

Las Trampas is one of the few parks which is accessible early in the morning. We started our hike at about 7 am with high hopes for spotting wildlife. There was the faint hope of seeing a Puma (Mountain Lion) since they have been seen here. We decided to take the trail leading to Las Trampas Ridge. Along the way we saw some of the usual birds. One interesting sight was a dead tree with 2 Acorn Woodpeckers and 2 Nuttal’s Woodpeckers foraging very close to one another.

Being amongst the early ones on the trail, we saw many animal tracks on the patches with loose soil. We were able to pick out Deer, Coyote, Fox, Bobcat, Raccoon and some bird tracks. We also saw Gray Fox scat, indicating a diet of seed and berries.

As it got warmer we started seeing Western Fence Lizards. Our hopes were to see the Coast Horned Lizard, especially since we saw sandy soil and many ant colonies. Instead we were rewarded with another lizard species, its scales glistening in the morning sun. We got great views of a Western Skink, a new species for me!

Once we crested the ridge, we got great views of Mt. Diablo, Highway 680 and Walnut Creek. The view westwards was still a bit hazy. We noticed a stock pond, a bit off the trail and proceeded to check it out. Some cows came by to drink water but the pond life seemed to tolerate their presence.

There was bird activity near the water and we saw Lark Sparrow, Goldfinches, both Towhees and a Hermit Warbler. I managed to get two new species – a dragonfly – the Common Green Darner – and a damselfly – the Familiar Bluet.  There were also some Variegated Meadowhawks.

After scanning the edges of the pond for a while we started noticing the Pacific Tree Frogs that were well hidden. There were some almost grown up tadpoles. We were puzzled by air bubbles rising up every once in a while. Then we noticed something coming up to the surface and disappearing again. It was a real treat when we were able to make out that they were California Newts.

The rest was all downhill, literally and figuratively. The long walk back, in the heat, was rather uneventful. We did notice a lot more activity from the Western Fence Lizards along the edge of the wide trail (a dirt road) including an abundance of small, baby lizards which should have been a lot warier of potential predators. And the quest for the Horned Lizard continues …

Field trip to Morgan Territory, East Contra Costa Co.

On Tuesday morning, I drove to Morgan Territory Regional Park for a hike hoping to see some of the general wildlife of the area. Morgan Territory exhibits classic East Bay habitat and there are no parking fees.

For most of the time, I hiked along Volvon Trail. The trail was very easy to walk on and provided wide views of the beautiful surroundings. A couple times, the trees would open up to stunning views of Mount Diablo.

The soft, sandy earth on the trail was excellent for seeing footprints. The occasional animal footprint would be mixed in between both dog and human footprints; I identified Puma, Raccoon, and Deer prints. For the greater part of my hike, these prints were the only evidence of animal activity – everything else was very quiet. Still, the scenery and vegetation made for a wonderful morning walk.

Towards the end, however, things started picking up. As I was nearing the last quarter mile before the trail head, I heard a slow, consistent rustling in the grass off of the side of the trail. I knew this was a snake. The only other small creature which makes such a noise in the grass is a lizard, however lizards produce short bursts of rustling – not slow and constant. I peeked a little bit closer and realized it was a Western Rattlesnake. It is extremely important to be careful around rattlesnakes and give them their space so as to not disturb them. I was fairly close to this one, however it was calm and not rattling. It merely waited in the grass to the side of the trail until it determined I was not a threat. I was standing perfectly still, and so it decided to continue on its way, gracefully crossing the trail and going off on the other side.

Western Rattlesnake at Morgan Territory

Rattlesnakes are beautiful animals and aren’t dangerous if we, as humans, are smart about how we act around them. They are fairly common and widespread in these East Bay hills, so encounters are relatively frequent. Many rattlesnakes are killed. Again, smart actions on our part could avoid both rattlesnake and human misfortune.

I continued on the trail and came to a pond. As I approached the pond, I heard several loud “plops” near the water’s edge. These “plops” turned out to be California Red-legged Frogs jumping into the water from the banks.

As I was watching the frogs, a Coyote came out of the woods on the far side of the pond. The Coyote leisurely poked around several California Ground Squirrel holes that were on the hillside, and didn’t notice me, allowing me to take some nice pictures. It even tried digging into a hole to get at a squirrel, but failed.

As I turned back to looking at the frogs in the pond after the Coyote, I noticed an Aquatic Garter Snake swimming in the pond. As I got nearer though, it disappeared under the water, topping off the wonderful animal sightings I had on this day. Overall, I felt quite lucky to have seen 2 species of snakes, Red-legged Frogs, and a Coyote all within the period of an hour.

Mines Road and San Antonio Valley, 8/10

I drove along Mines Road and San Antonio Valley early this morning hoping to see some reptiles. In the past, I’ve seen Gopher Snakes, Aquatic Gartersnakes, and Western Rattlesnakes along this road. However, none were to be found today.

The main highlight of the day was a herd of Tule Elk resting under some trees in San Antonio Valley. They were quite close to the road, and easily seen from the car.

Other mammal highlights included both Desert Cottontail and Black-tailed Jackrabbit off of Mines Road. Birdwise, I saw a Greater Roadrunner and a California Thrasher, both very interesting species that aren’t seen often. I also saw a pair of Turkey Vultures feeding off of a California Ground Squirrel carcass on the road and took this picture:

While they are quite common, Turkey Vultures are still quite a sight to see close up.

Tesla Road, 8/9

It was a great night for an evening drive along Tesla Road in eastern Livermore. The objective was to look for San Joaquin Kit Foxes, but we failed to find them. Kit Foxes are both nocturnal and extremely difficult to see. We did, however, manage to see several other species of Bay Area animals.

As the evening light faded, we first spotted a Tarantula as it was crossing the road. As we were attempting to get him out of harms way in a timely manner, it managed to crawl into the wheel on our car. After several minutes of banging a stick on the tire, it finally decided to come out and wandered off to safety.

As we drove along, we also saw a Gopher Snake cross the road. When threatened, Gopher Snakes tend to sharpen their heads so that they resemble something like triangles, something we had noticed before while driving along Mines Road which is also in Livermore. This one was no exception.

Driving a little further east on Tesla Road yielded two Western Rattlesnakes. We managed to snag a picture of the second one, its eyes gleaming in the headlights. Note the defensive position.

The fact that we saw three snakes as well as a tarantula crossing the road combined with a decent level of traffic shows how easily animals can become roadkill. Drivers must be careful always.

On the way back, we saw a Barn Owl fly along the road for a bit and then veer off. And then a Desert Cottontail by the side of the road. No Kit Foxes but plenty of wildlife.

Coyote Creek Lagoon, 6/28

A quick walk in Coyote Creek Lagoon last Sunday yielded little overall diversity of species, however we had great sightings of a Forster’s Tern dipping and flying in breeding plumage.

A big flock of American Avocets, Marbled Godwits, and Long-billed Curlews also took off in beautiful shapes and patterns. Other interesting species seen were Snowy Egrets (also in breeding plumage) and Common Ravens.

Field trip to Lime Ridge, Walnut Creek

This trip marked two special things. One was Father’s Day. The other was the start of our search for the elusive Coast Horned Lizard. We had read about some sightings in Lime Ridge Open Space and decided to head there. Our walk in Lime Ridge was through some fairly open grassy slopes, interspersed with some chaparral, rock outcrops and a few trees. We were keenly eyeing every sandy patch on and off trail and getting our hopes up at the sight of each ant colony we encountered. As usually happens with wildlife outings, we ended up seeing several other interesting species.

One avian highlight was the Rufous-crowned Sparrow. We had several great sightings and heard 2 different vocalizations. Before this we had only gotten fleeting glimpses or distant looks. Other nice fillers were a pair of Ash-throated Flycatchers and four Bewick’s Wrens in one tree.

It turned out to be a good day for insects. We saw 6 species of butterflies – Common Buckeye, Anise Swallowtail, Variable Checkerspot, Acmon Blue, Mylitta Crescent and Cabbage White. My second “officially” recorded species of odonate (dragonfly) – Variegated Meadowhawk. To round out the variety of animal life we also saw a mother Black-tailed Deer and her young one. And a fat, flattened-out Western Fence Lizard really got our hearts racing.

We ended up empty-handed or rather empty-eyed. We could not locate the Horned Lizard. But the search will continue. You can see some great photographs of the Horned Lizard here on wildherps.com. Lime Ridge is located at the foot of the northern slopes of Mount Diablo. Much more information about our local wildlife and wild areas is found on sfbaywildlife.info.

Users Advisory Group, 6/18 – East Alameda County Conservation Strategy

I attended about the first 50 minutes or so today, June 18th, of the Users Advisory Group meeting for the EACCS. To get some background, please go to their website here.  Their website has a lot of good information. I would like to praise them for the amazing job they have done with utilizing their website to distribute and publicize information about the strategy. Posted on the website are past meeting minutes, future meeting agendas, detailed drafts of the strategy, and much more. I encourage you to check it out.

I feel from my perspective, that of a wildlife enthusiast with no particular agency loyalty or technical background, I hold a unique perspective on these meetings and I can draw out information which would be pertinent to the general public. If you want more objective background of what was discussed or more details to substantiate my opinions below, again please look at their website for meeting notes or other documentation.

For the amount of time I was there, there were two points other people made that stood out to me in particular. The first was the issue of “keeping common species common.” One individual (sorry I did not note who) made the point that the strategy was concentrating too much time on focus species such as the Red-legged Frog or the California Tiger Salamander, and neglected to address the common species. The individual asserted that common species are the true marker of an ecosystem’s health. A member of the steering commmittee said there were regulatory reasons for addressing the focus species, among other reasons. There simply aren’t enough resources available to members of the strategy to save every specie in every habitat. I agree on both counts. Common species are intrinsically linked to the focus species, as all wildlife is linked in various types of food chains or mutualistic partnerships which should not go unnoticed. But the issue does remain that generating political capital to even implement strategies such as this is extremely difficult, and we should use our resources wisely.

The second point that struck me as interesting was the idea of working at the regional level as well as the habitat level. From my limited understanding of the strategy, I can see it targeting various species and various habitats – identifying the ones that are in need of conservation based on a number of factors. However, another individual pointed out that regional conservation was important as well. By this, he meant preserving landscapes and areas. Preserving the shape and nature of the East Alameda County as a composition of a variety of habitats and species is a different perspective than targeting specific habitats and specific species, but it is another valid perspective. Habitats and specifies do not function by themselves, and we as people who enjoy the beauty of nature do not generally see isolated habitats and species. What we see are landscapes and regions composed of a multitude of things. Therefore we should consider their conservation as well.

Another point I thought of while the meeting was going on was the issue of the “general public.” The strategy, as far as I have seen, uses factors such as “focal species needs” or “habitat goals” to produce conservation guidance and mitigation guidance for the strategy, but one variable I did not initially see was what I call the “appreciation” variable. I believe making natural places accessible and well-known to the general public should be a factor in this strategy. This is one of the goals of sfbaywildlife.info. I will do more research about the strategy before I hold additional judgment.

All in all, I am very impressed so far by the collaborative, modern, and open effort to create a conservation strategy for East Alameda County.
