The Hayward Shoreline had been a regular hangout for us Quails when we lived nearby and I still miss going there on a regular basis. Last week I solidified a tentative plan I had to take my family hiking group there on Sunday and since it has been a few months since my last visit, I decided to go there on the Saturday before.
On Saturday morning as I was getting ready Pappa Quail and the younger chika said they'll join me.
Surprisingly, the elder chika decided to stay behind.
The sight that welcomed us at the parking lot was very similar to what we saw when I was there for the 4-H hike a couple of years ago - a puddle of rain water on the road and a gaggle of geese using it as a water hole.

California ground squirrels are plenty there. Not that t's difficult to see or photograph hem, but they're so common that we hardly bother with it anymore. Still, they are very cute to watch and usually also very cooperative photo models. I was surprised to see how many of them live between the boulders right at the water line - a precarious home choose considering the long reach of the bay water.

We entered the Shoreline from the W.Winton gate intending to hike south along the Gogswell Marsh and finish at the Hayward Shoreline Interpretive Center. I had left my bike at the Interpretive Center to get back to my car when we'd finished the hike.

The bay waterfront never gets snow, but the thick layer of Coyote Brush seeds can give the impression some times.

And even as late in season as December, something will always be blooming along the coast. And most often the blooming plant would be of the aster family.
|
Gumweed, Dec. 2 |
We walked along the slough toward the Bay waterfront. Great egrets are permanent residents of the Hayward Shoreline and are sure to be seen there, usually nearby a great blue heron.
|
Great Egret, Dec. 2 |
We hardly ever note the presence of mallards anymore, since they seem to be everywhere. But Pappa Quail did photograph this pretty drake, saying he looked very cute.
Saturday was gray and overcast but Sunday was clear and beautiful. We had a terrific view all around and a nice, clear view of San Francisco across the bay.

While we didn't have that great view on Saturday, we did get to see many, many birds. Most of them - shorebirds. And most shorebirds look very much the same to me. There are some, however, that are quite distinct and easy to identify. The curlew is one of these species, and it is almost certain to see them any day in the Hayward Shoreline.
|
Curlew, Dec. 2 |
The greater yellowlegs is also a fairly common shorebirds but I am never sure about its identity unless I see its legs. And even then it could be mistaken, if its legs are too muddy to show the if yellow color. Thankfully there are two real birders in my family, and I leave the identification to them.
|
Yellowlegs |
And some bird I identify by default. A quarter of a mile south of the canal mouth the trail curves back inland along a second canal. There at bank of the second canal bloomed a tobacco bush. That tobacco is a non-native species and I didn't pay attention to it on Saturday. On Sunday however, I did photograph ot. It looked pretty n the sunshine, but the main reason was the little Anna's hummingbird that was feeding from its long, tubular flowers. I knew it was Anna's because it is the only hummingbird series that overwinters in the Bay Area.

That trail segment leads back inland along a low and flat hill. Low and flat, and dry land with drylands vegetation, that is home to many little bush birds.
|
White-crowned sparrow, juvenile, Dec. 2 |
Pappa Quail made sure none of this little brown birds escaped his camera. He also took the time and effort to identify them. I don't think I could have.
|
Golden-crowned Sparrow, juvenile |
Past the low hill the trail turns back south and takes right through the wetlands. On a levee at first and then on a long overpass.
The wetland is being taken over by an aggressive non-native cordgrass that chokes the native pickleweed. There is much concern about this but I'm not sure what will be or can be done about it.
|
Cordgrass, Dec. 3 |
When I hiked there with my hiking group on Sunday, as we walked along that part of the trail a large gaggle of Canada geese that were on top of that hill suddenly took to the air in a big commotion. It didn't take long to see what had startled them - a glider parachute hovered behind the birds. It must have looked like a huge raptor to them.

Much of the Shoreline trail is on levees that used to hold the salt pond of Cargill Corporation. Many of these salt ponds were made nature preserves and sone were converted back into sat marshes. The conversion involves the breaching of the levees and allowing bay water to flood the wetlands with the tide cycle.
At the time of our family hike there in Saturday the tide was low. Very, very low. The little cove that opened up when the levee was breached was a wide mudflat with just a trickle of water on its side. The mudflat was covered with shorebirds of different species. They were all busy feeding - poking the mud for the mollusks and crustaceans that leave there.
|
Feeding Grounds |
Papp Quail took close up photos of the feasting birds. They were of the usual crowd that flocks to the low tide mud exposed: sandpipers and other little shorebirds.
|
Dunlin |
The dunlins were the bigger in this flock, and they were mostly stationary, methodically feeding at the same spot of their choice.
The smaller sandpipers foraged more and kept moving around, poking the mud here and there, then moving on to a different spot to poke some more.
|
Least Sandpiper |
The sandpiper movement between the dunlins gave the mud flat a constant shimmer and shine that was very pleasing to see.
|
Western Sandpipers |
In the fringes of the feeding flock foraged a few bigger birds. Not part of the flock but keeping a close distance to it.
|
Willet |
The bridge over the levee breach is long and as is very common, we saw anglers sitting there with their lines in the water. The west of the bridge on the bay side also showed exposed mud flats extending quite far into the bay. This particular corner seems devoid of birds but the image is cropped - there were quite a few shorebirds poking in the mud to the left of the image.
|
Exposed mudflats, Dec. 2 |
A cloud of small birds circled the water, then came together into a long thin line formation close over the water surface and flew north.

While I was looking toward the bay Pappa Quail focused on the birds feeding in the mud.
|
American Avocet, Dec. 2 |
While all the birds we saw that day were the same old crowd we were quite familiar with but it was cool to see them feeding and sometimes squabbling. Pappa Quail got some very nice behavior shots of the feeding birds.
|
Curlew eating fish, Dec. 2 |
And there was much food to go around. Fish and crabs and everything else mud-living that thrives so well in the SF Bay tidal zone.

I wonder where all of these birds go when the tide is high ...
|

A jogger came by from behind and past us. All the birds that were feeding down at the cove not minding us or the angles took flight. A cloud of birds of at least three different species, all moving in unison, their wings shimmer in the faint sunlight, shadowing the shiny mirror-like mud below.
|
Dec. 2 |
I followed the cloud of birds as it murmurated to and fro, eventually flowing over and across the bridge and settling on the mudflats on the bay side and resume their feeding.
|
Dec. 2 |
The cove, previously teaming with the foraging shorebirds was now empty, displaying only the thin trickle of water extending from the salt marsh to the bay.
|
Dec. 2 |
Quite a striking contrast with how the exact same place looked like on the following day, at the peak of high tide.
|
Dec. 3 |
The high tide on Sunday, December 3, wasn't any regular high tide but a
king tide, when the water rise particularly high due to the combined gravitational pull of moon and sun. The sight of the multitude of birds were not there of course but we were duly impressed by the beauty of the flooded salt marshes and coves.
There are very few spots along the trail where it is convenient to just sit and relax. One such point is at the edge of the former levee past the long bridge over pass where there are makeshift (and nor very stable) benches and a very nice view of the bay. When I was there with my hiking group the wind was blowing strong and cold so we didn't stay there for too long.

Dec. 3 |
Going on southward and closer to the San Mateo Bridge the trail splits. The left turn leads east and back north to complete a loop around the salt marsh. That loop
I hiked a couple of years back with the Redwood 4-H Hiking Project. Now we were continuing on south to the Hayward Shoreline Interpretive Center.
There too on Saturday the birds filled the low tide -exposed mudflats. The mud shone and flickered in the sun that was already setting at the time.

Between the Salt Water and the Sea Strand, Dec. 2 |
On my hike there on Sunday everything was flooded and the water sparkled blue under the bright early afternoon sun, complementing very nicely the reddish pickleweed.

Salt marshes play a very important role in the Bay's ecology. One of its functions is the purification of water, done naturally by microorganisms that live in the mud. East of the salt marsh is the City of Hayward Wastewater Treatment Facility where the city's wastewater is cleaned to a point it can be released back into nature, making its way back into the bay.

The trail leads south along the shoreline for almost a mile past the overpass bridge. Then it curves back east and inland, a slough on the north and SR 92 on the south, with a narrow canal and another field of pickleweed in between.
The tide was already coming in when Pappa Quail, younger chika and I made it around the curve and over the little bridge across the slough. It was cloudy, and getting near twilight time.
|
The slough, Dec. 2 |
That bridge is where cliff swallows build their nests in springtime. There were no nests there this time of course (I did check!).
On the following day the tide was receding when me and my hiking group arrived to the same place.
|
Dec. 3 |
The
sun was shining bright still and the current going out to the bay was
strong. Little shorebirds were already appearing at the narrow, newly
exposed strip of mud at the slough banks.
|
Receding Tide. Dec. 3 |
While we didn't see any swallows nests there that weekend, there were warblers present and Pappa Quail photographed one on the fence near the slough.

That almost of a mile between the bay shore and the Interpretive Center is a
trail I've hiked many, many times. It took me a while to figure out what was that toppled-looking wind operated device that's lying there by the water and when I found out it impressed me as a very cool idea. It is an Archimedes Screw - a wind-powered water pump. The idea is quite genius (as was its designer). The screw that us there is a model only and isn't used to pump the water though. There is a smaller model at the interpretive center where visitors can check the device in person.

The Hayward Shoreline Interpretive Center is Located in the last inland building before going on the San Mateo Bridge westbound. And inland isn't the most accurate description either because the building is elevated on poles founded deep in the mud.
I think it is a very cool looking building but the inside is also very rewarding as it has a shoreline nature exhibit room, an art display, and an elevated observation deck.
The center is managed by the naturalists of the Hayward Area Recreation and Park District (HARD) who run wonderful educational programs there for kids and for adults.

I left Pappa Quail and my chika at the interpretive center, found my bike where I had left it earlier and rode it to the W. Winton staging area to get the car. When I left the center the incoming tide was just beginning to flood the building area, and by the time I was back with the car it was almost dark.
Tides come and go twice every 24 hours. Each tide is different and a shoreline area looks different each day and each hour. The tide cycle is crucial to the ecological health of our bay shores. It is important to keep it coming.
