The water’s edge                                         July 2014

Placing together pictures of just a few of the amazing animals found in the Bay area near water. Most of these photos are from our Sacramento Delta system in eastern Contra Costa County. These pictures come from many driving adventures up and down the levee’s and back creeks where I can gain access. The Burrowing owl and dark phased Swain were inland in Oakley.

#1 recent Burrowing owl photo in Oakley area. #2 recent Musk rat in small creek near Bethel Island. #3 recent Great Egret near Holland Tract. #4 recent picture from the Swainson Hawk nest I have monitored several years and wrote much about in this blog site. This nest has stressed me out so many times as wind has knocked it into river twice and shore fishermen sometimes sit within twenty feet of nest. This year once again, the pair has succeeded in two fine young birds now close to taking flight. A great story in a rough year… #5 Last winter shot of Sand hill cranes on Holland Tract. #6 another profile picture of an Osprey at Los Vaqueros reservoir. #7 recent Western King Fisher at Clifton Forebay in Byron. #8 recent Dark phased Swainson Hawk in my Oakley back yard (Unbelievable) #9 Older American Bittern near Bethel Island. #10 recent Western Pond turtle basking on Holland Tract.

Pictures of the moods of  Burrowing owls

    The drought will be hard on wildlife this summer as small springs and streams dry up. Some have already fallen, in Southern California the wheels are coming off on the wildlife front. The Raptors have been in the news lately as it is so dry there is little food and less water. Here in our area it’s a mixed bag in my opinion. Some areas (Especially North of us) received enough water to get through this year. Other areas are turning bone dry right now or in the near future. Small streams, springs and cattle ponds in our areas are drying up quick and many of these are critical drinking water areas for wildlife. While the large reservoirs and delta system will no doubt help, many animals will be forced to travel looking for water. That’s when trouble starts. Some say there is an El Nino effect on the horizon, I sure hope so…

               For the most part I have stayed away from getting political with this blog or wildlife site. In this circumstance I am going to take a stand. In the photo with six owls taken in Byron, the burrow was destroyed. There have been many more as well.

    My issue of the Burrowing owls in eastern Contra Costa County mainly has been the routine disking / tilling of open fields usually pulled behind a Cat or tractor. I have seen communities of owls disked over during the breeding season for weed abatement / fire prevention. The disking has caused burrow collapse when eggs or young owls are underground and has forced many owls to use burrows on the sometimes un disturbed road shoulder which is subject to weed abatement spray, dumping of roadside debris and chances to come in contact with vehicles / dogs  and collapsing burrows from parking trucks.  My thoughts are if these burrows are flagged and identified, equipment could easily work around them leaving them intact. As a public works supervisor (Now retired) our crews were required to perform a habitat survey (Through an RMA agreement between C.C. County and Fish and Wildlife). This meant when working near these owls or other protected species we performed a habitat survey making certain the owls were not disturbed. This is even when we mowed in their areas and mowing alone does not destroy them. I have written Fish and Wildlife and contacted the burrowing owl conservation group asking the question “Why can’t Fish and Wildlife require property owners and agricultural land owners take part with the same requirements other maintenance organizations practice in the guidelines of protecting our wildlife species with the RMA (Routine maintenance agreement) habitat survey of areas long known to be habitat for Burrowing owls prior to work being performed? The outcome is always the same (As I have witnessed). A contract company will take no prisoners when tilling open fields, after all who can prove the owls were there. Enough is enough; this is a species of special concern…

Fish and wildlife and The Burrowing owl conservancy have not yet responded…

Days of Swains 
           “Updating local bay area wildlife photos in spring of 2014”. Lately I have been to Eastern Contra Costa County chasing burrowing owls and Swainson hawks. Hikes lately have included Black Diamond Mines S/O Antioch and Mitchell Canyon Regional Park on the north side of Mt. Diablo.  Soon these areas will be blazing hot though currently it is green and lush with plenty Oak trees and wildlife. I must say Mitchell Canyon is incredible with the variety of wildflowers this spring. (Bring $6.00 in change and place in envelope as the honor system is used at this park) Black Diamond Mines is free when no one is stationed at Kiosk which is most of the time.
                      In Eastern Contra Costa County this time the most common hawk in the sky may be the Swainson hawk. They are back and they are in solid numbers and this place would not be the same without them. The large slim athletic hawk cuts the wind like a knife and with an over confident attitude they put on a show daily harassing their soul mates and buddies with talkative dive bombing and erratic aerial skills. Some of this behavior is probably related to courtship while later it will be used teaching their young the strong flying skills needed for survival. In the eastern agricultural meadows and fields the Swains team together in large numbers when hunting opportunities suddenly become a boon for all. I have witnessed this past couple of years where mowing or dragging of fields is performed. The numbers of Swainsons vary sometimes more than fifty hawks are seen. When this occurs many of the Swainson participants have in talons a mole which they grip tightly or toss to another hawk. There are some incredible chase scenes involving several of the Swainson hawks showing off their banking and diving skills many times coming within a few feet of the ground and each other. It appears to be all in fun despite the continuing talking to one another with constant screams. The Swains seem to tolerate other species of soaring hawks during this event; even turkey vultures get a pass though I have seen Swains viciously attack Crows and Ravens then escort them off the playing field. I have shown photos of this process in the past. Looks like a mixture of what I have called air hockey or perhaps “Quidditch” seen in the Harry Potter movies without the broomstick and with perhaps a different scoring system.                                                              
                              These birds have an incredible migration each year even the Northern Cheyenne would be proud of. Observing particular pairs return to their nest sites is comforting realizing the journey they have endured. If you live in the bay area and want to get a clean close up look at these incredible flyers, right now is a golden chance to witness them in action. I would like to hear some accounts from other Swainson hawk enthusiasts in the Sacramento Valley. Seeing them gather in these large groups is relatively rare; however spotting a pair cruising the sky is very common. When not in the groups they live much like their cousins the red tails loyal to only their mates and off spring. I currently have found five active nests out here, though it is very important to give these shy birds their space as they may abandon the area if harassed. Earlier I have mentioned a banded bird I have monitored over six years. The bird and its mate are nesting again along a delta slough. Twice they lost their nest into the delta with the harsh delta winds. This pair has raised many youngsters and is the only pair I have gained close access too as they seem to accept my visits. Featuring recent photos  of our local Swainson Hawks…

April 2014

Here comes the Swainson Hawks and Burrowing owl. It must be springtime in the bay area!

             I always remember the first swainson hawk I see each year, this time was March 13th for me in Oakley, and they always come in with a decent entrance. Last year the first sight were two swains chasing a red tail away from their tree with some very exciting low level aerial scene I had to pull over and stop to observe. Camera in hand I couldn’t even get a shot of this furious action. This year my first sight were two hawks flying single file fairly low with the front bird carrying a field mouse. That’s no red tail. The swainson hawks are back. It is always a better world with them here. Also the burrowing owls will begin their breeding in East County and I will continue my plight against the tilling of burrows I have spoken of earlier.   
                Updating the Coyote Wars,
              The Coyotes have been at war with humans for many years. Listed as a varmint, nuisance or whatever they choose to call them they are the original bad guy. Many hunters (Not all) use the Coyote for target practice. People living in remote housing tracks and near wild areas blame their missing cats, small dogs and other random occurrences on the song dog, despite the fact they moved into the coyotes home country.  

      As mankind expands its city borders and developed areas, the Coyote improvises. They use trails, creek beds and other avenues to find a way to exist even in areas populated by man. stay low, cut and run, try not to allow the long riffle to get a clean shot. Change dens at the hint of someone knowing you are out there. Keep the youngsters hidden and be willing to re locate at a moment’s notice. Trust no one. No reason to be territorial and this goes against many theories of other species. Song dogs were not born yesterday, they are smart. They show expressions of cockiness, happiness, sadness and displeasure. These song dogs are survivors. The good news for coyotes is that watershed land and regional park property has assisted their plight for survival. Lands that were once open for trigger happy shooters are now controlled by habitat restoring Regional Park. There was a time long ago when the sheep herders fought the golden eagles in the west. Like the mighty golden eagle these song dogs have improvised and overcame.  Worth repeating is the Lakota saying concerning “The Coyote”

“The Buffalo will disappear, then man shall be gone and there will be total darkness. And in that darkness the unmistakable call of the song dog will be heard.”

Eyes of the Osprey                                                                        March 2014

               The Ospreys are back in strong numbers, and the crystal clear lakes of California now free of DDT are a literal paradise.  The bandit of the sky with “the dark mask” is perfectly adapted with bendable elbows in those wings and an extra thumb  nail on the talons for grasping the skeletons of large fish. Bald eagles often set its sight on stealing the fish from the ospreys. There are always some unique aerial displays between the two over the prized catch.
               Now days, every body of water around these parts now have ospreys. I have even seen them over drinking water canals and small creeks. Recently, I have a located a particular bird at Los Vaqueros reservoir southern entrance who catches a fish and lands on a utility pole on the walking trail very close to the visitor center. Several people walk by and many stop and admire. They take photos of the osprey on their cell phones and show their children the incredible predator of the sky. It takes this bird nearly two hours to devour a large trout as he takes his time. My theory of why he is unafraid so close to humans may be that this area is UN desirable for Bald eagles who have much less trust of us humans. I stood there over an hour and observed this bird constantly stare to the sky with nothing passing by without a glance. The only change in demeanor came when an adversary osprey circled the area. At that time he screamed vehemently and made sounds I had never heard from an osprey.  I have returned a few times to Los Vaqueros and have witnessed this same bird using the pole for his feeding perch. It’s almost becoming a daily show here at the reservoir. It’s true, the ospreys are back and I am including a couple pictures of what many natives called the fish eagle. If you visit there drive to the end parking lot and walk towards the buildings. Look at the utility pole top along the walking trail.  










 
I realize I am always bias towards birds of prey, I can't help it.
