#SilentSunday It is night in the city where there’s a five story building where the front is only lit up. Small li windows reveal shops are along the dark street. There are a few red unlit Chinese New Year lanterns strung across the street.

Yellow-Rumped Warbler was on the backyard cultivated Native California Grapes just long enough for this fortunate shot. #Birds #YellowRumpedWarbler #Fujifilm 🪶A Yellow-Rumped Warbler in a grape vine that’s losing its red to brown leaves. The pointy beaked warbler has a yellow neck and chest. It’s gray and white elsewhere. The bird is staring at something off-frame to the left.

Here’s the turkey that appeared out of a hollow at Point Reyes National Seashore (years ago) and tried to steal our lunch. #Birds 🪶A turkey, showing its side, staring menacingly at the camera. The bird is about waist high and is standing next to a well-worn log. Its beak is bright and sharp.

Orange-crowned Warblers are back, feasting on dried out grapes. We’ve also observed Yellow-Rumped Warblers in the grapes. #Birds #OrangeCrownedWarbler 🪶 #Fujifilm A yellow bird straddles a thin grape vine among red and yellow grape leaves.

Snow Geese are back in Northern California. It’s nice living in a fly-way. #SnowGeese #Birds #Fujifilm 🪶Snow Geese fly above in a haphazard V formation. They’re all white with black wing tips. The sky is blue with wispy clouds.

Walnut trees in Northern California right now. 20 foot or so spaced rows of walnut trees with their bright yellow fall foliage.

We had a distinguished visitor in our backyard today, hunting at our feeder. This is a Cooper’s Hawk or a Sharp-shinned Hawk. Absolutely stunning. A hawk perched in an elderberry bush. It has rust red bars on its white chest and a dark brown back. Both its yellowish eyes are looking forward toward something off to the photographer’s side.

Good morning. The time changed so I’m now technically up an hour early but I got the usual hours of sleep. So here’s a likely Savanna Sparrow from the Sacramento National Wildlife Refuge A small bird perched in dense brown reeds.

I’m still amazed how the beta blocker Propranolol means I no longer have a physical tachycardic fight/flight response to normal situations like hobbies, people, and work. Game changer. Makes managing anxiety much easier.

Mastodon.
