Sweet innocent Ms. Chicken... recently has been hiding under a bush in the backyard. She holds perfectly still and makes a strange soft whirring sound. This usually signals to me that there is somehing scary in the vacinity....

A Sharp Shinned hawk (Accipiter striatus ) has been to the feeders in the past, taking a few doves and I saw it yesterday in a tree above Ms. Chicken's favorite bush. Ms. Chicken is very smart about these things. She barely blinks an eye and I wonder if the hawk notices her being so still, or perhaps hopes that Ms. Chicken will move out of hiding. The hawk's visual system is so keen I can't imagine her not seeing Ms. Chicken.

This afternoon, one of my neighbors had feathers strewn all over the front yard. I had just left the house and did not say good-bye to Ms. Chicken. I was struck by the obvious evidence of a kill and I had to make sure it wasn't anybody I knew.... Towering above the neighbor's house is a huge four story Deodar Cedar (Cedrus deodara) and just about 5 meters up there were white feathers on a branch. Apparently, the hawk captured a white dove and feasted on it earlier in the day. I was relieved.

Sharp Shinned hawks, after killing their prey (birds), carefully pluck out the feathers. Cats, on the other hand, dive right in, bite the head, and tear open the body cavity... so do dogs. Cats and dogs (coyotes) eat the birds from the inside out leaving an over coat (and smaller chunks) with feathers.... Sharp Shinned hawks like to tear off beak sized pieces of a fully plucked prey.The hawks also like to take their prey to some place where no one will disturb them... like cats... dogs eat on the run (like us) so, the branch full of feathers was typical. Now, did the hawk leave anything behind like the beak or claws ...?

It is cold and rainy. I am not sure how folks can sit out in the rain to watch the Rose Parade every year - but they do. This is the first year in 51 years that it has rained on the parade. It didn't just sprinkle, it poured. And after the parade - every year - the City people from the Water and Power folks to the Trash collectors to the Sewer Maintenance all have to pick up, tear down, re-wire, fix, you name it because of the influx of a few more million people in this small town. The trash is particularly disgusting.

At 3:30 p.m. we had a small electrical outage in my neighborhood. Damn! I was working on something on the computer and while fixing a cup of green tea (and to do some thinking) BLIP! So, I rebooted my Mac....
Then again, at 4 p.m. the power went out on the entire street again. The sky was so dark it could have been night. The rain was getting monotonous. I could see there were flashing lights up the street near the main pole. I decided I could go to some store or another (but wasn't interested), sit in the dark, try to read by candle and flashlight, or go out and watch the guys fix the power. I chose mixing with the power folks.

Fred, the cat, seems to have a penchant for tripping me while I walk to the back door... and in the dark he's got his technique for maximum effect. When I was a kid I used to walk around in my dark room to see if I could remember where things were and could get around as if I were blind. My mother never understood why I like to bumble about in a dark room.... I suspect it must have seemed peculiar. I never ran into things - much. However, the practice in my ill spent youth allowed me to find, in a dark closet with lights, my tripod and my camera and I was able to attach the two together. Fred stayed inside while I went to schmooz with Pasadena Water and Power Maintenance Crew.

There were five trucks two of which had 'buckets' one of which was headed for the top of the electrical post. The heavy winds and rains caused the tall palm trees to drop their heavy palm fronds, The fronds have huge serrated stems and one was straddling all four wires. There was a pile of them just at the bottom of the pole.

Several of the guys were actively watching the workers in the bucket and so I thought I would ask a few questions about the procedure for fixing the downed line. They were happy to talk about what they were doing. One of the guys n the bucket took a pole and shoved the frond off the wire and the wires arched.

Then I asked if Pasadena's power plant at the end of the Pasadena Freeway produced enough power for the whole city. One of the guys seemed very interested in describing how our City gets power. Apparently, our fair City helped another or more... fair cities build their large power plants in Oregon, Utah, Nevada,... gosh, I wonder where else?... so we can buy power from them. The Old Pasadena Power Plant was just too small to produce power for the numbers of new households in the city. As I listened I wondered if and when those other Cities would get too big for their britches... and where would we ALL get our power from?

Like a pyramid game, there comes a time when we can't get any bigger. In fact bigger is not better. Growth becomes a reallllllly bad thing. Sustainability, or worse, stasis will be the word of the day.... Now, that many of us are starting to contemplate a time when oil will not flow like water, and cities will have to be self supporting. Suburbia and all that goes with it will be the monstrosity it really is. Individuals owning cars filling up every open space on the surface of ground will be ridiculous.... and all of this could come rather suddenly... Roger Rabbit will fold his arms and say "THee, I told you so!"

Sediment-in-reservoir

It was my birthday today so, I visited the mountains with a friend. What better way to cheer on another year.

The last couple of days the mornings were cool with some fog and then the sun, in early afternoon, would peak out and warm things up. Two days ago it was 87 FÂș in Pasadena - nice. I have been planning to go visit the upper watershed and hoped it would stay warm, but alas, the winter clouds won. Still all in all it was lovely.

Water was still pouring in the East tributary of the San Gabriel River. Most of the small waterfalls off the sides of the mountains have been spent. All summer Public Works have been hauling the sediment from the bottom of the reservoir to another location in the mountains to make room for water in the reservoir behind the dam for next year's winter's rains - and to supply water for drought impacted Los Angeles County.

Dams are funny things. We build them to save water and yet they have a limited 'life' span or usefulness. Rivers are a bodies of water which flow from high places to a lower places - they have a much larger body of water beneath the surface in the soils flowing generally in the same direction, albeit slower.The trees and rocks and animals are swept up in the water, too. The flotsam and jetsam that flow on the surface bring minerals to the iron starved oceans and the sediments enrich the effluvial fans surrounding the rivers. The process distributes the plants, animals and water to the surrounding lands, eroding the mountains away. Before people, the washed out trees, brush, and sediments provided protection from predation, material for breeding, and food in the form of islands for the various ocean going organisms.

We build dams. Then rains and snow-melt, which soak through the soils in the mountains, fill the rivers with water. The force of the water washes sediment down the mountain. The sediment fills up the reservoirs behind the dams, which lowers the depth of the man-made lakes. Depending on the amount of rain, and the decomposition of the mountains' soil and rocks, the man-made lakes can, with some bad luck, be filled and useless in ten to twenty years.

I need to visit the new mountain Public Works created from this summer's dredging of sediment....

Last Thursday before Christmas the sky was full of these strange clouds. It looked like the clouds wanted to have rain - if you can HAVE rain - but something kept happening to the water droppets. The drops would fall and then get sweeped up back into the air. These silly vapor bags were hanging all over the central vlley of the Los Angeles basin. They somewhat reminded me of a sow's teats.

Down under in the bushes and roses, this small bird was turning up the leaves on the floor looking for little yummy bits to eat. Perhaps, a ground beetle, or a earwig, or a snail, or a centipede hiding under a twig in the moist soil. All I could hear was the shushing of the leaves below.

Birds are funny little animals. They are curious, and if you make the right noise they will stop what they are doing and come out from hiding to look at where the noise is coming from. Two sparrows were just above the Junko and my walking closer made them fly away. "Chi-Chi! Chi -Chi!" I said and up came this little bird to look.

Ginkos, a friend once said, never learned how to be trees - they were too ancient. They grew branches and stems like the lobes on Equisetum, also an ancient plant prior to the Cretaceous Period, sticking straight out perpendicular to the trunk. Oh, but the leaves are so unique and so yellow in fall and early winter here. In China, I have heard people eat the fruit.

Oh , the fruit! They drop to the ground in fall and when crushed, smell like a mixture of dog poo and cheese. However, it is said that they offer good medicine in the form of a vaso-dialator used to help those who forget stuff... Some formulations suggest only using the leaves. Even the yellow jackets that buzz in fall, stay away from the smelly things.... I use them as a deterrent to stepping on my plant beds next to the street. First time steppers in fall are reminded that something was rotten where they last parked...

Aix gatericulata, Mandarin Duck

Back at Desconso Gardens... the camellias are revving up this winter and many are open. Some are loosing their petals. All are beautiful and delicate..

How is it that SOME males, like this duck, know how pretty they are and need just that special position to show off? Perhaps prance a bit. Bat its eyelashes. Maybe, take a deep sigh just to show how the rest of the world doesn't come up to its standards....

The male Aix sponsa, Wood Duck, isn't someone to sneeze at. He's beautiful. He's willing to sit next to the Mallards.... Anas sp..

Cicindela no longer run in the San Gabriel Mountains. There are streams and ephemerals that flow all summer long and would be perfect for tigers. When and why they disappeared is not known. Perhaps corralling the streams and rivers into a single flow into a reservoir and the aquifer for the valley below, destroyed their habitats. We will never know.

My grandfather worked with Roger and Vincent and Bella ... and even let Ed Wood use his studio on Yucca to do some of his ... eh hem, films. Ed Wood scared my mother (who was a kid) when, for a lark, he took his teeth out to prove his disability from World War II. Peter Lori used to visit at my grandparent's home and was apparently quite a funny man despite his dower appearance. Vincent Price was an art collector and loved my grandfather's work. It is too bad I wasn't there to enjoy the ghoulish crowd.

How can it be? It's winter! Damn! I miss the smell of flowers and the buzz of the bugs.

Birds still visit my yard - mostly sparrows and finches. I tried to entice a scrub jay to come down from his tree with a carrot - but he thought I was nuts.... "What do you mean a carrot. I want a peanut!"

California has seasons just not as dramatic as having snow. In the San Gabriel Valley you can watch snow come and go with the rain... it rains down here and the snow drapes on the mountain. I love and miss the flowers...

The Gingko tree is bright yellow and that's wonderful. I sweep the leaves and sprinkle them about the front of my yard between the bushes. The contrasting yellow on the ground is beautiful. I hate throwing away leaves. It is still not cold enough to have killed off the frantic yellow jackets.... they are a nuisance.

The crickets are still singing here and there. I miss them at night in winter. I have some of this wonderful red Delphinium cardinale - a member of the Ranunculaceae family. They are six feet tall and love the dry weather of California. My blue Delphinia continued to bloom until last week...


The best thing about winter are the cool nights..... the short days, the lack of crickets, the few birds, the grey skies.... nah!

eggs


eggs
Originally uploaded by tardigrade.
Ernestine, the leopard tortoise had another batch of eggs...

Ernestine's eggs from last night are on the left. Miss Chicken's are in the middle. And the right two eggs are from the market and they are Large Grade AA.

It is cool outside right now at night. The sun makes the day warm and the tortoises bask. But, last night Ernestine broke through her cage and started digging a hole with her back feet to deposit her eggs.

Ernestine had found a spot of just dirt and she started to dig in it with her long back claws. The soil is dry so she urinated in it to make the soil easy to dig. Ernestine has a huge capacity so the area was as wet as if I had poured a quart of water at her rear.

For three hours she dug and finally she put her head in and pushed hard. Her tail wagged and a clear mucus dripped and then her first egg appeared. It seemed as if this was not only a Herculean effort, but a painful one at that. The egg dropped slowly into the wet soil of the six by 12 inch hole. Each egg was wrapped in this clear mucus that allowed the egg to touch down slowly on the others without a sound. The egg shells are similar to chicken eggs except when the mucus is removed they are more porous.

After the ninth egg she was so tired. She tried to close up the hole but it was around 52 degrees F outside at 10 p.m. and so I decided to bring her inside. I put her in the sink and filled it with warm water. Her eyes were sunken from dehydration and I hoped she would drink as she normally would do. She kept moving her legs as if she was still outside trying to fill the hole with her eggs.

Ernestine does not have a mate and so her eggs are sterile. In the same way as Miss Chicken lays sterile eggs because she, too, does not have a mate. Miss Chicken has several 'times' a year when she is ready to lay eggs. Her personality changes and she does this little dance when I come close to her - I suppose she sees me as her 'mate.' Miss Chicken 'chucks' at the kitchen door to be let in and then finds her spot. She will spend approximately an hour laying her one egg. Ernestine, on the other hand lays many eggs all at once.

Inside Ernestine's egg is very much like Miss Chicken's egg. There is a white and a yolk. Some people like to eat turtle eggs.... like those who like chicken eggs. Sometimes it is hard for me to eat one of Miss Chicken's.... I don't think I can eat Ernestine's..... I will stick to tomatoes and almonds and other plant materials ....

Ah, poor Ernestine. I have looked after her since 1987 when she was the size of a grapefruit. I think that leopard tortoises, Geochelone pardalis, are so beautiful. I bought Ernestine from a pet store whose owner adored tortoises, too. She introduced me to her vet who to this day still comes to look after the menagerie.

Ernestine in action... HERE

Leopard tortoises need to be warm in the sunlight and have access to water - they love to sit in both. When I moved to Ohio these requirements were difficult to adhere to but the house in Ohio had old fashioned radiators under the kitchen sinks. So, I would keep Ernestine in a black plastic cement mixing container on the counter. She also had a light to increase her exposure beyond what we had in the more northern latitude.... and so Ernestine grew.... and grew.

One fateful day, Ernestine now a full 18 inches long and almost 20 pounds, felt she needed to get out of her confinement.

My young daughter and a friend sleep beneath over in the basement in a room for guests beneath the kitchen. In the dark of morning they heard what they thought to be rain falling but, instead they awoke to find the ceiling tiles floating in a foot of water in the basement. They got up in a panic to find water coming down the walls and the stairs ..... Up they rushed to find Ernestine had slipped out of her cement mixing bucket and into the kitchen sink. She had tried to get out of the sink and had turned the hot water on her self. By the time we all saw the deluge, the water was cold... but Ernestine had burned herself quite badly.

The vet in Ohio had me give Ernestine anti-bacterial injections because her neck, her front legs, and her back legs were swollen and smelled of infection. Flies started to infest under her shell but one of the other smaller tortoises kept an eye on the maggots and followed Ernestine about for small snacks. Eventually, Ernestine healed but the scutes on her upper carapace fell off.

How big do leopards tortoises grow? Well, in 1993 I traveled to South Africa, where these reptiles are from. I was standing next to my hosts near an open field near the back brush. Down below in a clearing I spotted something about 3/4 mile away that looked very familiar. I yelled. "it's a tortoise!" and ran down the hill with a small crowd behind me not understanding my glee. I found a small coffee table sized female leopard tortoise which, could have weighed over a hundred pounds.... and out from the bushes around her were four or five males - around 25 to 30 pounds. I brushed her back and found a few ticks the size of the end of my thumb attached to the soft part of her carapace between the scutes. She never flinched as I touched her. Wonderful!

Ephydridae and Chalcididae


Looking at sticky trap after sticky trap full of so many insects I get very 'antsy'.... sorry.... Funny thing, the 280 8x8 inch sided sticky traps are different from the 280 sticky traps from last year and the year before and the year before that.... What is the difference? Well, this spring had a large storm event that took out a large portion of the Mugu Lagoon habitat. It probably caused changes in the upper watershed that flows into Mugu. There are different genera and families this year. There are many more individuals as well.

Why would something so devastating like the spring 2005 storm event cause so much change? ~ More families, more species more numbers???? Also, there seems to be more parasitoids and hyperparasitoids. This Chalcid wasp (on the right) seems to be stuck on traps in large numbers with even larger numbers of Phoridae.... Are Phoridae parasitized by Chalcids??? (The fly on the left is an Ephydridae a very salt tolerant Diptera)

Sticky traps are like trying to understand ecology in the La Brea Tar Pit style.... When 'A' falls in and gets trapped in the tar pit (sticky trap), it may have been chased by 'B' which, when stuck is attacked and killed by 'C' which is then eaten by 'D'... The difference between digging bones out of the tar pits and identifying insects mushed on sticky traps are different exercises.... oh my aching eyes...

Please note that the larger fly is only 2 mm .... and that there are wasps a quarter the size of this particular Chalcid!!!!

What does Miss Chicken know about impending doom?

In the morning she is happy to see me and chortles with delight as I take her from her cage to the tool shed where I keep her corn. I take a handful and sprinkle it on the ground at the entrance to the back door. She has a special vocalization that she makes when she has found something very delicious like a worm or spider ... or her morning breakfast. The cats walk carefully around her and she watches them closely, too. Sometimes she likes to take a few mouthfuls of their dry food.

I let her roam the backyard for tiny insects. Slugs, which she grabs with deftness, throws it back into her gullet. Happy chicken. Sometimes I buy meal worms for her as treats. The happy sounds that she makes. If she is across the yard and sees me with one in my hand, she will run with her grey skirts flying to snatch the writhing larvae from my fingers.

Sometimes she gets lonesome and calls for me. She used to have a friend but she died several years ago from a heart attack. Miss Chicken hid in the bushes for days. She makes a different call to me when a hawk comes to check her out. or if stray cats come to hunt for birds. When the hawk alights on the fence she yells 'chuck chuck squawk!' If I come home too late at night and she is not at the backdoor for some reason, I hunt for her in the trees.

One night I could not find her. I looked everywhere with a flashlight. I am sure the neighbors think I am crazy. I went to bed sad knowing the raccoons sneak in my yard to hunt for fish in the pond or.... Then in a terrible squawk, with a deep throated clucking she screamed for help. The dark night made it hard for her to see. I jumped from my bed and ran out the side door to find miss chicken had gotten away once again from the jaws of the raccoons. She sat under the light outside and I picked her up. She was quiet when I put her in her cage.

So from where did this terrible H5N1 come from? I know the people in China do not think about their birds like I do - but perhaps some may. One virus or up to ten of them can cause her to be very sick and she would have less then half a chance to live. I carry her about and give her a kiss on her head, so I, too, could become sick from this disease. Where would it come from?

Doves like to clean up her corn that she does not finish. Could they carry it? At night I hear geese flying could they drop it in my yard somewhere in their excrement? Could the raccoons carry it to my yard? or the squirrels? I am in the pathway of the green parrots - could they bring it to us all?

I bought her for five dollars from a ranch not too far away from my house. I found an ad in the throw away papers. I miss not having a chicken in my backyard. She was an adult bird and sat on other birds eggs she is a brooder. She is and has always been a very personable bird and loves to follow Eddie my gardener about when he digs or trims or sweeps.... When she laid eggs, she is now past that time in her life.... she preferred the kitchen counter. To inspire her, I would put my iPod in the towel next to her. She would pull the iPod by dragging it with her 'chin' under her feathers. She would sit on the iPod until her body was ready to expel her egg.

I don't see myself not caring for this animal. What to do....

Meromyza sp


Meromyza sp
Originally uploaded by tardigrade.

This is a mangled specimen. I have been identifying insects caught on sticky traps for Mugu and the Institute of the Environment and this poor devil was a mess. Also, I have never come across this animal at Mugu on sticky traps nor sweep nets nor Malaise traps. I was stumped!! So, I asked a wonderful entomologist friend to help me out and he said it was in the family of Chloropidae.

Chloropidae. It is one of the very few I have ever seen at Mugu with so very little coloring in its exoskeleton. The haltare was turquoise simply because of the thickness of it tissues. The face was triangular, and it seemed to have a eyespot on its 'forehead.' The femur of its back leg was thick and it had stripes on the dorsal side of its thorax.

One website from Cedarcreek said it was a grass fly that liked to buzz around eyes and wounds. Another said it liked aphids. The three specimens I found on sticky traps were peppered with aphids. In fact, there were more aphids then thirps this season. And, there were more parasitic wasps then from other years.

Could have the storm events of last spring changed the configuration and abundances in the Mugu insects?

Here is a much better picture of this Meromyza sp..

http://cedarcreek.umn.edu/insects/album/029094050ap.html

I have been counting and sorting insect traps and worms from core samples of the soils from Mugu. This is the hard part. Collecting is the easy part. I love collecting and walking and finding new animals.....

Last day at Mugu


My friend and I went to Mugu on Friday, September 30. Beautiful day! But, it was our last day. So very sad. I suppose that the Navy is tired of biologists counting and assessing the plants and animals. Or maybe they are tired of scientists who watch the environment. Or could it be it is not the Navy who does not want us, but those who direct the Navy and other military bases which have the highest number of endangered organisms in the country. Perhaps, with what they do for a living - what they stand for, they hate the idea they must be stewards of important plants and animals.

My friend took this picture of me as I was looking at the different holes in the ground and walking with my net and camera. There were terrible fires in Chatsworth and Ventura the last few days. Ash was falling and drifting all over for many miles. Some of the solitary bees' holes had been usurped by spiders. Maybe, the bees were hiding deep into the ground while the spiders were borrowing the upper chambers because, there were little webs covering the holes festooned with ash.

Tiger hunting


My friend is a fine hunter of tigers.

The first step in hunting these wonderful animals is to spot them as they stand tall on their long graceful legs like slim twigs on the hot salted soils. Then, you must walk carefully - not letting your shadow cross over them because they will either disappear into the background or fly into the brush. Crouch low with your net out in front and holding the netting with your other hand... in a quiet moment wait for the tiger to clean itself.... then BLAM! Into the net. The tiger struggles in the netting. Its metallic carapace glistens in the sun. It tries to fly and then tries to find an open or torn spot in the net... You wrap the net around the struggling animal. You take the fierce tiger in your finger tips as it gnashes and slashes at you with its sharp mandibles. Such fantastic creatures!
