Tangled Up In Blue

 

Crow & Hawk in Urban Web of Life

I was sitting at the front gate after putting out a couple of used bike tires for someone to come pick up. I'd just put them on Craigslist "free stuff" and someone responded right away. It's been my experience that people don't always come, even after saying they'll be right over. And they never tell you that they've changed their plans. Non-human animals are much easier to understand.

The cat (who's doing much better after getting some medicine from the vet) was sitting with me, enjoying the afternoon sunshine. When a large leashed dog made a lunge for her, I was proud to see that she hardly flinched while giving him her best "Keep walking, buster" look. As the dog and its walker headed down the sidewalk I saw the crow that had been squawking. The cat doesn't like crows, but this crow wasn't squawking at a cat.

I'd been thinking about bringing my camera along on my bike rides for the last couple of weeks because I've been hearing and seeing red-shouldered hawks more than usual. In a nice twist of fate, this one actually came to me, perching on the web of wires a few doors down. I don't think the hawk was bothered by the crow, but I probably got a little too close for its comfort. Either that, or it gave up on the white-crowned sparrow that had been singing so boldly from the top of the bush below, but was now safely hidden in the shrubbery depths.

Mountain Cams

 

Snow on the Mountains, March 2, 2023

I wasn't able to make it up to Mt. Tam when it snowed on Friday, February 24, but at least my trail cams were there, and thankfully some passing deer set them off. The lens on one of the cams had a big glop of snow obscuring much of the view, but even that was kind of fun to see.

What surprised me when I biked up there yesterday was the view toward the city, with snow still clinging to the peaks of the inner coast ranges, at least 65 miles away.

The one surprise on the cams was a couple of people who hiked through along the deer trail, coming from who-knows-where. There are no marked trails anywhere near there. I'd love to know where they started out and where they exited. They noticed both cams and the woman contemplated dancing for one of them, but the guy didn't seem into it. The one cam that picks up audio gave me a smile when it caught the guy looking at the tiny Foxelli cam and saying, "This doesn't exactly look official, does it?" I've seen a couple of the "official" cams, and he's right. Theirs were bigger, much more expensive, and were either out of reach or locked to something, or both.

It's so rarely low tide when I pass this point going to and from the mountain that I couldn't resist stopping to snap a picture. The tide had been much higher when I rode by on my way up the mountain a few hours earlier. Compare with this scene from when I was there a little over a week ago. The black-necked stilts, American avocets, and wigeons were all still there, along with numerous gulls who were feeding on the Richardson Bay mud flats.

In this composite image showing the bobcat moving across the frame, it looks like the cat is moving directly toward the second cam. I couldn't believe it when I sorted through the more than 2,000 frames from that cam, many of which simply showed trees blowing in the wind, and could not find the expected pictures. I figure the cat either darted up the hill after leaving the Foxelli frame, or the second cam simply malfunctioned at a very inopportune moment.

Rainy Days

 

Storm Squall Floating Over San Francisco

The wind chill was almost certainly dipping into the 30s yesterday (~45 degrees w/ 25 mph wind) as I waited for the squall above to blow into rainbow position. It felt downright wintry in the stiff wind that was blowing most people off the top of Grandview Park after just a few minutes of taking in the view. 

I had seen the squall on internet radar and drove over to the park in the hope of catching a big bow over the city, but it was not to be. A little bitty fragment showed up briefly, but even that scrap of color was gone before it drifted into a more interesting position over the city.

I had hoped to try again today, but Coco, the semi-feral neighborhood cat that we've been feeding (and sheltering on cold or rainy nights), seems to have come down with something, and I'm still waiting to go pick her up from the vet. I wasn't prepared for the sticker shock of going to the vet since I haven't been to see one in probably thirty years. Wow. Hopefully they'll get her back to her frisky self soon.

Bird Flu for Bandies

 

Band-Tailed Pigeon

I just read that band-tailed pigeons are having an outbreak of Avian trichomonosis (which is caused by a protozoan rather than a virus like bird flu, but I took alliterative license in the title of this post). So far this season an estimated 200-300 of these sleek and colorful California native pigeons (Patagioenas fasciata monolis) have succumbed to the virus, which thankfully is a far cry from the estimated 18,000+ that died during the record-breaking warm years of 2014 and 2015. Meanwhile, an estimated 5,600 birds were taken by hunters in the Pacific Coast region in a recent season, which lasts only eighteen days (it's split into two nine-day seasons by region).

Infection with avian trichomonosis isn't always fatal to the bandies, but it can cause lesions in the upper digestive tract that block the passage of food and even air, and eventually cause death. The birds encounter the parasite from contaminated water or food, and adults can infect their chicks when feeding them. The parasite, Trichomonas gallinae, can infect domestic fowl and other wild bird species as well, including raptors that eat infected birds.

Bird feeders and baths are believed to be sites of transmission of the parasite and should be cleaned regularly to help prevent infection.

Grandview Park

 

Rainbow Over the Richmond District

I was browsing the internet this morning with my oatmeal and coffee when the sun started breaking out. I wondered if I might have time for a walk down to the beach, so I checked the weather radar and then the Ocean Beach web cam. 

The radar showed that rain was almost certain to get me, but I was surprised to see on the Ocean Beach cam that snow had fallen lower than I'd expected on Mt. Tamalpais. I bolted from the computer, grabbed my camera gear, and drove over to Grandview Park to try to photograph the snowy mountain. 

Unfortunately, even in the short time it took me to climb the steps to the vista point, a phalanx of clouds moved into to obscure the snowy ridge. For just a couple of seconds near the bottom of the stairs I had been able to see the whole mountain from the ocean to East Peak adorned with a frosting of snow, but by the time I reached the top and set up the camera, huffing and puffing, the mountain heights were almost completely obscured.

I hung out for quite a while, hopeful that the mountain would reveal itself again, and shot some time lapse footage instead of just standing in the cold. No luck on the clearing. Meanwhile a dense rank of storm clouds was blowing closer and closer, and with the first few drops I packed up and took refuge in my car. 

The storm passed over, by and by, and a rainbow began to form over the Marin Headlands. I grabbed my gear and started hiking back up the stairs when I stopped to photograph a ship heading out to sea, disappointed that I couldn't have caught it closer to the foot of the rainbow. The ship turned out to be a vehicle carrier called Cetus Leader that had just left its San Francisco anchorage bound for Nagoya, Japan.

It was interesting to see the rainbow so low on the horizon. A little later I thought I might see another bow as a squall moved perfectly into position, but by then the sun was so high that no rainbow could be seen (42 degrees above the anti-solar point, where the rainbow would be, was well in front of the rain squall).

Snow on Mt. Tamalpais

 

Snow People on Mt. Tamalpais, Feb. 20, 2011

I forgot my snow shots weren't already on the blog (except this one), so I thought I'd post them in light of the possibility of getting some new snow this week. I doubt anything like this 2011 snowfall is in the cards, but you never know.

Sand Check

 


The Great Highway had an unscheduled automobile closure today, courtesy of Mother Nature.



Two phone snaps from the edge of the dune.



I avoided this bike/pedestrian path yesterday because the wind was even stronger, making this stretch look like it was being sand-blasted. Looking back the other way, a car is taking a detour through the Beach Chalet's parking lot because there is deep sand accumulated on the Great Highway, and not just here but in many spots along the front of Golden Gate Park.



I was going to head back up through the park when I noticed huge waves crashing into Seal Rocks: guano cleaning, courtesy of Pacific Power Wash. I was also amazed to see a group of sturdy young people doing a beach clean-up. They should have had some news media down there. I was not surprised when their supervisors called them in shortly after I packed my camera to get the heck out of that cold wind.



Luckily, this tree (one of several newly fallen trees since yesterday in Golden Gate Park) broke in two in just the right place. :)
