At the Park

Coots first came up from the ditch on November 1, and by November 3 were able to find the grass on the lawn. The main source of food for coots in winter in California is from eating the grass in large parks and golf courses.

On the next day coots arrived that must be returnees from last winter. They could be readily hand fed and were eager to eat corn. Wild coots around here usually won't eat corn, and certainly won't take food from strangers.

A large grouchy male coot guards the water dish. Notice the feathers standing up on the back of his neck. Coots will fight over anything of value. But this one is an excessive case. Maybe one in a hundred coots are both aggressive and fearful, and never establish a close relationship with either coot or human.

There were some surprises in feeding these birds. Other sorts of food is provided for the crows. One coot snatched a chicken bone meant for a crow, and another ran off with a dead mouse. I don't know how or if these items were eaten by the coots. There have been reports of cannibalism when coots are forced to eat coots that have died from starvation. Coots are called omnivorous, but I was thinking of something like insects, not rodents.



At the Boat

At the boat, various numbers of coots come and go in the first week of November. One male individual is there faithfully evey morning about an hour before sunrise.

By the middle of November, he is able to climb up the coot ladder and eat the corn and drink the water there.

He is very wild and shy, and difficult to photograph. The color in his toes indicates that he is probably a returnee from last year.

The shape of this coot's frontal shield is quite distinctive, and makes him easy to recognize. (above)

Around November 20, a lesser scaup arrived at the boat and seems to have been accepted by the coot. This little duck may have been the one here last year. The coot still fights off any other coots that happen to try to move in.

On November 29 a few new coots are at the boat in the morning at five AM. They must be returnees since they know to climb up on the boat's swim step immediately and find food and water there. The previously resident coot is quite angry about this.

Another Sign

Drought Sign

The Port who has been flooding the lawn with water like a rice paddy for years, has now decided that there may be a problem with the water. El Niño is, however, bringing some water this winter that helps the landscape. A Scripps researcher mentioned the fact that without the current climate change, this would be just another normal year for rainfall. San Diego citizens continue to meet and exceed government standards for water conservation, but most of our critical ground water is used up and would take years of normal rainfall to replenish. Conservation is never a solution to a permanent problem, but it will do for now, until our current city and state politicians are gone.


Crazy Pigeon

early riser
The crazy pigeon with the odd hairstyle is still often seen in the park, but is not bothering the crows so much this month.



A Different Bird

night heron
Night Herons are rare in the marina, but common where they nest in the tall trees across the bay at North Island. The recently fledged juveniles have an especially endearing appearance as they seem to show an expression of astonishment at everything they see. This is the first time that one ever came to my boat.



Friendly and Helpful Crow

FRIENDLY CROW

I was late going over the park, so the friendly female crow came to the boat to find me. The crows must know that the hostile swallows are done nesting and gone for the year. The crows were always afraid to come down to the docks since the swallows were sure to attack tham. She looks around the dock and boat, examining stuff she has never seen before. Finally, she acts as if she wants me to follow her back to the park and flies and hops along the dock toward the parking lot.

Sunken Warship Brings Sea Life To Ocean Waters Off San Diego’s Mission Bay- KPBS"The wreck of the Canadian destroyer Yukon is a magnet for divers looking for adventure near the San Diego coast. The ship is also attracts a wide range of marine life. Citizen scientists are documenting the area to help understand how the wreck is affecting the underwater environment." --It is a somewhat deep dive for inexperienced divers, and a few have been killed on the Yukon. Also, the ship was in National City for cleaning and cutting large holes in the sides to make it safer for divers to escape. The holes were roughly covered with plywood and explosives were added so it would make a spectacular "explosion" when it was to be sunk the next day. Unfortunately, the sea was a bit rough when it was towed out of San Diego Bay to the sinking site. Pumps aboard were unable to keep up with the leaks, and the ship rolled over and sunk laying on its side. When everyone came to watch it sink the next day, it was already gone. This adds to the confusion of someone trapped inside. I have never found it very productive for fishing. It's too deep for bass, and you don't have much time for fishing before the divers arrive. As soon as they put up a dive flag, you can't be anywhere near it.--editor

In wake of collapse fears, feds to assess anchovy populations. Monterey County Weekly "The last assessment of anchovies—a key food source in the local marine ecosystem—goes all the way back to 1995, and a group of scientists that include retired National Oceanic and Atmospheric Administration scientist Alec MacCall have recently argued there is evidence of a widespread collapse of anchovies off California. "

In wake of collapse fears, feds to assess anchovy populations. MIT News "In the new process, called shock electrodialysis, water flows through a porous material —in this case, made of tiny glass particles, called a frit — with membranes or electrodes sandwiching the porous material on each side. When an electric current flows through the system, the salty water divides into regions where the salt concentration is either depleted or enriched. When that current is increased to a certain point, it generates a shockwave between these two zones, sharply dividing the streams and allowing the fresh and salty regions to be separated by a simple physical barrier at the center of the flow."
