Barn Owls

On Friday (2023-07-07) my granddaughter and I saw two barn owls in a large pine tree. There were three nests - one was about 2-3 times the size of the others. A juvenile was next to the largest nest staring down at us. We briefly saw an adult flap its wings and then settle down into one of the smaller nests. Unfortunately, I didn't have my camera that day, so we went back on Wednesday (2023-07-12). We didn't see the owls, but evidence of their presence was there: bird droppings on the sidewalk, many feathers and we counted 9 owl pellets.

Snapshot Cal Coast 2023

Snapshot Cal Coast Bioblitz (June 17 - July 9, 2023)

Day 1 (June 17, 2023; 171 observations; 94 species)
I walked the 4.4 miles around the Sunnyvale WPCP Pond in the Baylands near the Sunnyvale Recycling Center.

  • I recorded 21 species of birds, but it seems there should be more. There perhaps a hundred or more mallards out on the bay, with some ruddy ducks, an occasional gull, cormorant, and a few pelicans flying overhead. There have been days when I've seen dozens of species in one day. Where are all the birds?
  • I saw two mallard families with a total of 16 babies. Always so sweet!
  • There were so many lizards and they all look quite different. I couldn't resist photographing all of them.
  • The pond turtles were out sunning themselves. Yay!
  • The water was so green!
  • Predators have been busy. I saw 2 dead ducks, a few gull wings, and jackrabbit remains.
  • I recorded 49 species of plants. Unfortunately, only 15 were native and 12 of the 34 non-natives are invasive species.

Day 2 (June 18, 2023; 125 observations; 76 species)
I visited Don Edwards National Wildlife Refuge and surveyed the area around the visitor's center because the main trails are still closed due to construction. I also briefly visited the nearby Alviso Marina County Park.

  • The coyote brush shrubs and California buckeye trees look so healthy after all the rain this past winter. Last year they looked very shriveled and pathetic after many years of drought.
  • I recorded 14 species of birds - many were different from those I saw at Sunnyvale Baylands. Black-necked stilts and cliff swallows were the most common species.
  • There were a few lizards, but not nearly so numerous as at Sunnyvale Baylands.
  • I recorded 49 species of plants: 27 were native and only 6 of the remaining 22 non-natives are invasive species.

Day 4 (June 20, 2023; 82 observations; 55 species)
I visited Coyote Creek Lagoon at Don Edwards for a couple hours. There were a few species not found at either of the previous locations. I didn't photograph most plant species that were also found at the other two sites. I saw 19 species of birds.

Day 9 (June 25, 2023; 172 observations; 86 species)
I visited two locations in the South Bay: (1) the area where the Guadalupe River flows into the bay, and (2) the perimeter of Salt Pond A4 near the Sunnyvale recycling plant. These are the only areas I know of in the South Bay where you can actually walk along the shore. Alviso Marina & Don Edwards are doing maintenance work, so their shorelines are closed to the public right now.

  • The trail was almost completely obscured by 6-7 ft. tall smilo grass, oats, mustards, Cretan mallows, and thistles. It was like walking through a dense prickly jungle. Not pleasant. As soon as I was able to get down to the shore, I walked there instead and found lots of small crabs, a few clams and mussels, and a turtle carapace.
  • There's an interest in saline-tolerant Quercus, so I've been documenting every Q. lobata that I run across in the Baylands.
  • I've seen very few honey bees this season - quite alarming!
  • There are a lot of artichoke thistles (Cynara cardunculus) around Pond A4. I know they're non-native, but they're huge and have beautiful purple flowers, I think they're pretty, and the yellow-faced bumble bees love them.

Day 12 (June 28, 2023; 123 observations; 72 species)
I walked the Adobe Creek Loop Trail at Shoreline Mountain View for a couple of hours. At the northernmost point, the tide was receding, so I climbed over rocks to get to the shore to find some shells. Bad idea! I inadvertently stepped in sinking mud up to mid-thigh and I was afraid I wouldn't be able to get out by myself. I got a taste of what it must've been like for the animals at La Brea Tar Pits. I eventually pulled myself out, but I was covered in mud from head to foot and had to walk the 2 miles back to my car looking like the creature from the black lagoon. So humiliating! But I got some good pictures and found a few more species not documented at the other sites. My favorite sighting of the day was the big black-tailed jackrabbit resting in the shade.

GPS wasn't set properly

I somehow screwed up when setting my phone GPS to record. Ugghhhh! I hate when I do that. Had to set all locations for my Joseph Grant observations manually, to the best of my memory.

Coyotes at Ed Levin County Park

It was the day of the coyote at Ed Levin. I saw three coyotes and got some good pictures. What beautiful animals! One climbed the hill and then sat down and watched me take pictures. I was able to get recordings of the coyotes, too. That was exciting!

Some people had a doberman off-leash and off-trail. The dog was following two coyotes. I told the guy to put a leash on his dog and he cussed me out. I was wondering if the two coyotes would kill that dog?

Bear Creek Redwoods - a magical place in the winter

It's been a long time since I've hiked Bear Creek Redwoods. I'd forgotten what a magical place it can be in the winter. So many beautiful mushrooms, lichens, ferns and moss.
I thought my camera's battery was fully charged, but I guess not. It ran out of juice halfway through my hike. Maybe the fact that I had to use the flash for almost all the photos drained the battery faster than usual. There were so many more things I wanted to photograph. I'll have to go back soon.

Collecting data on local Malvas (May 2022)

There seem to be a lot of misidentifications of Malvas in the San Francisco Bay Area. I'm on a mission to learn as much as I can about these plants and help identify the observations for our area. I've been posting many observations of Malvas in the South Bay, hopefully with enough evidence for proper identification. In most cases I'm taking measurements either with a ruler or millimeter grid paper.

I've created an umbrella project with subprojects for each species in our area:

As I gather more info, I'll create a "How to Identify..." journal post for each species along with "How to differentiate..." sections for similar species and references to Calflora, Jepson, and others.

Some things I've noticed:

  • Malva multiflora (Cretan mallow) tends to grow near the Bay and waterways (e.g. Calabazas Creek).
  • Malva parviflora (Cheeseweed mallow) and M. nacaeensis (Bull mallow) can be seen all along the trails at Ed. Levin County Park. They are very small plants and sometimes look the same until you inspect them closely. Some of these plants I could hold in the palm of my hand they're so small.
  • Malva assurgentiflora (Island mallow) and M. subovata ssp. bicolor (Sea mallow) are mostly cultivated. There's an established population of M. assurgentiflora at Shoreline. Is it wild or cultivated? There are several M. assurgentiflora at Ulistac Natural Area, but they were planted by humans.

Lots of big animal bones

There's an area I hike at Ed. R. Levin County Park that seems to have an inordinate number of big mammal bones (6 deer and 6 domestic cattle since November 2020). Makes me wonder if a mountain lion lives nearby? Bones found at Ed R. Levin County Park.

A good day for Black-crowned Night-Heron (Nycticorax nycticorax) sightings

There were dozens upon dozens of Black-crowned Night-Herons today at the Baylands - too many to count. I'm happy to say there were lots of juveniles, too.

There were also lots of Brown-headed Cowbirds, Ruddy Ducks, Northern Shovelers, and surprisingly, several patches of Datura.

Gall Week 2022

Darn! My GPS wasn't set correctly, so I don't have accurate coordinates for my observations for Sept. 10, 2022, the last day of Gall Week 2022. Thankfully, I only covered a small area within Ulistac Natural Area, so it won't be too difficult to set approximate locations. But still... I hate when that happens.

City Nature Challenge (2022) - San Francisco Bay Area

I visited these 4 places for the City Nature Challenge 2022:
Day 1 (29-Apr-2022, 5.5 hrs): Sierra Azul OSP, Limekiln & Priest Rock Trails
This was one of the best days ever! I've never seen so many species and I even spotted some new ones (for me).

Day 2 (29-Apr-2022, 2 hrs): Sunnyvale Baylands
Took a short walk around the hill and paths by the water treatment plant to get some photos of sea birds. Saw 9 turtles sunning themselves - all native. (My feet were hurting from yesterday's 5.5 hr. hike.)

Day 3 (01-May-2022, 4 hrs): Joseph D. Grant County Park, Manzanita Trail to unnamed pond
Walked with my granddaughter Faith. She's great at spotting small things. She caught a water snake, newt babies, a tree frog, and tadpoles with her net (catch & release). It was a blast!

Day 4 (02-May-2022, 2 hrs): Ulistac Natural Area
It was an overcast windy morning. Not ideal conditions for photographing birds, plants & bugs.

572 Observations
313 Species
