The Shy & The Bold

 

Northern Flicker, Golden Gate Park

The oak woodland around the Horseshoe Courts was very birdy today, as was the Fuchsia Dell across the street. I was surprised to see so many flickers and varied thrush. It felt ridiculous at one point where every step I took flushed another unseen flicker from wherever it was feeding on the ground. They are very shy birds.

The new growth of grass, miner's lettuce, fumitory, oxalis, manroot, and other groundcover was tall enough to completely obscure the presence of the flickers, which are as big as robins. You expect little juncos and other sparrows to be unseen down there (my first-of-season white-throated sparrow was "the one that got away" today), but not their much larger kin.

There were also quite a few varied thrush in the same area as the flickers. I walk by that area once a week and have never seen it so busy. When the brown creepers flew onto some nearby trees I felt an embarrassment of riches, having to choose which bird to aim for.

On a side note, I've been feeling like my collection of field guides has been relegated to the nostalgia bin by sources available on the internet. With apps like Plant Net, Merlin Bird ID, and iNaturalist, who needs to thumb through field guides anymore? Also, our small bookcase of field guides is right next to a larger bookcase of CDs, which I also rarely pull off the shelves anymore since it's so easy to play music off a smartphone. And when I want to re-read a regular book from our shelves, I often check to see if it's available as an ebook from the library, and read it on my tablet instead. 

Still, there's something nostalgic about all those books and CDs. I moved so often in my life before I met my wife that I never accumulated much stuff. I used to be such a minimalist that I'd always be throwing unnecessary things away (and occasionally having to re-buy them later!), but now I'm surprised to find myself comfortable with all our stuff. 


Even though it's easier to get identifications online, it's still enjoyable to thumb through one of these old things once in a while.

Varied Thrush in Dappled Light


I was surprised to see the varied thrush snag an acorn and fly off with it.


It was kind of dark beneath the oaks, so I popped a flash on this relatively close brown creeper.


My shutter speed had to be low enough for the flash, but I forgot to increase it when I switched my aim toward a flicker, resulting in a slightly soft disappointment.

The varied thrush were generally very shy, but occasionally one would risk exposure to resume feeding.


With so much activity, I wonder if the varied thrush and flickers are nesting here in the city.

I didn't see this hairy woodpecker break into any of those round black cramp balls, but it looks like somebody did.

It was surprisingly un-birdy at the Lily Pond this morning. I haven't seen the green heron in the last two or three weeks. I liked how the red-eared slider above showed its plastrom as well as its carapace. It seemed interested in something above it and to the right, but I couldn't tell what it was.


I've become addicted to the Big Bear Eagle Cam. I checked in last night when I saw on the news that SoCal was getting a storm, and found this incredible scene of the nest full of snow.


The sitting eagle was taking it all in stride, seemingly completely unperturbed by the cold snow and wind.


When the other adult flew in to trade places, the resting adult stayed put.


The other guy stuck around for just a bit to make sure its services weren't needed yet...


...then exited, stage right.


I've usually got the web camera open on another browser window when I'm working at the computer. If I hear eagles calling out, I switch over and get the screenshot clipper ready.


This time, the eagle who'd been sitting on the chicks immediately got up and flew away when the other adult arrived. Note the two chicks are getting close to having their sibling emerge from its egg. It seems to be quite a long process -- more than a day -- for the chick to break out after opening the first pip.


Just as I was about to post this entry, the other adult returned.

Heron's Head & India Basin

Black Oystercatcher, Heron's Head Park
 

It was so cold as I rolled down the hill from home this morning that I almost turned around to get warmer clothing. Or maybe even just stay home. My speed on the descent is generally 20-30 mph, making the wind chill on a 52-degree morning about 44 degrees. "But it's so sunny out," went my thoughts. "It'll be warmer when I start pedaling at the bottom of the hill."

But I never did get truly warm because even out at Heron's Head and India Basin, the sun would become obscured by clouds as strong winds blew over the water. It was a relief when I ducked behind a big bush and out of the wind at Heron's Head to watch American avocets feeding along the shoreline.

The tide was heading out to a noon low of 0.0 feet while I was there, bringing to the mudflats several willets, whimbrels, black-necked stilts, greater yellowlegs, a spotted sandpiper and a black-bellied plover, and even a pair of black oystercatchers in addition to the avocets.

There was a pair of mockingbirds trading songs over at India Basin Shoreline Park. We used to have these guys in our neighborhood, but somewhere along the line they disappeared.


Here's the lone spotted sandpiper, with a black-necked stilt for size-comparison.

I started to ride past the goats thinking I'd pass them up, but then I smelled them and had to pull over to check them out at close range. Something about hitting two senses -- sight and scent -- must have made the difference to draw me in.

From Heron's Head I rode along the coast to the Fort Mason Community Garden where I spotted this swallowtail fluttering in the breeze. When I saw it again a little later it landed on this plant, and I realized it was an anise swallowtail.

(I was able to find a single yellow egg on the plant, but it was far too tiny to photograph with the FZ80D.)


Not a great shot, but I liked all the colors.

...then gets up to feed the chicks. Note the hole started in the third egg.

I missed it when the second eagle came in, so I don't know if this was a changing of the guard.


The farther eagle takes off a second later.

Cooper's Hawk

Cooper's Hawk on Weathered Power Pole, Forest Hill

 It's pretty rare that I spot a perched cooper's hawk around the city. I'll see them in the air from time to time, but that's about it. Back in July 2011 I was spoiled by an encounter with young cooper's hawks in the S.F. Botanical Gardens (back when it was called Strybing Arboretum). All these years later, I still think about those hawks and hope to get another opportunity like that.


The band-tailed pigeon nest is still there, but I couldn't tell if there are any chicks yet. It's possible the pigeon is keeping them warm under its body. It's surprising to see how insubstantial the nest is.


As part of a construction project in someone's yard, this cross-section of soil revealed an interesting display of subterranean tree roots.


This is the cooper's hawk as viewed through some magnolia blossoms.

I immediately stopped my bike as the red-tailed hawk swooped down to pounce on something nearby, but it flew away just as I got my camera out. Luckily it actually flew closer to me by landing on this eucalyptus tree.


Take-off.


These are some of the cooper's hawk shots I got back in 2011 with a Nikon D300S.







Here's a screen grab from the Big Bear Eagle Cam, with two chicks having hatched.


When I checked the cam just now I noticed all the snow has melted from the nest.
