July 2016 Local Bay Area Wildlife  

There is a great July show in the sky, and it’s not fireworks. It’s our area raptors. Many on the hunt for their new young, others sitting nests feeding and covering the young in this hot weather, while some just cruising way up in the thermal air drafts. We are very fortunate to have the varied species of interesting raptors in our bay area. Please watch out for young birds and animals new to this world, and please do not use rat poisons. If you see bait boxes around buildings or businesses, I can’t see anything wrong with speaking respectively to the owners about removing these boxes for the good of our environment. Poison contaminates the entire food chain recklessly, and no one wants to be responsible for the carnage. Change is coming; we will be the ones lucky enough to see it through…

            Summertime raptors and other interesting characters, happy Fourth of July! Young white tail kites are back in my area, though I haven’t been able to witness the training sessions like last year. Swainson hawks are thriving in eastern CC County, and the nest sites are numerous. I am once again monitoring my favorite family who has three youngsters again; hopefully all will make it through. Anyone interested in viewing photos of the maturing season of the youngsters let me know, I would be happy to Email their progress once they are ready…  

Thanks, Dave

June 2016 “Heroes and Villains” Bay Area Wildlife update

*Happy Memorial Day! Thanks for our War Veteran heroes who keep us safe and secure.

Dry winds and warm days are sweeping through our bay area turning the hills to gold and bringing on the summer. It is a tremendous time of year for those of us enjoying the outdoors and wildlife.

I received a response from Fish and Wildlife regarding my concerns relating to the status of burrowing owls in eastern Contra Costa. I was satisfied with their response,  a warden came out, provided information and viewed areas over grazed by goats in small sections of creeks and flood basins. Something is not right, wish I could figure it out.

Due to a leg injury, my hiking has been curtailed considerably lately. Feeling better, I plan to get out and hike in remote areas soon. Lately, I have shot many photos from the roadside perspective.

Burrowing owl-  hero of course. Who doesn’t like these owls?
Tule elk-    hero, especially to all the babes he is hanging with.  
Red breasted sap sucker-    villain, even though wood peckers destroy trees, they many times go after diseased trees actually assisting with quick disposal and ground structure for other wildlife.  
Barn owls-   heroes no doubt. Proper rodent control. Willing to work late night shifts.
Rattler-   Villain, and proud of it. Another rodent controller. Comes with warning device.
Black tail buck-   Hero, I would only shoot at these with a camera… Can be jealous, and antlers were designed for making things right and clearing things up.
Long billed curlew-  Hero, once rare and hunted, these large ground foragers making a decent comeback. Witnessing many together walking fields is always a welcome sight.
Swainson hawk-  Hero, tremendous flying skills, loves to vacation down South. Provide great rodent control.
*Just playing on the words. All wildlife is awesome. All interesting in its own way.
Thanks, Dave.

Bay Area Local Wildlife May 2016

"Raptors and Cats" No update on Burrowing owls just yet, though I am expecting an email from Fish and Wildlife.
Not at all impressed with the burrowing owl conservation network. (If their is such a thing)
I am still going to get some answers from someone on these issues.
Had to reach back to some B side photos for a couple of these as my luck and chasing time has been slightly off during the last month. It is a beautiful springtime out there, even the cattle ponds are holding water... Interesting note: For the first time ever, I have found more bobcats the last two months than coyotes. And everywhere I go someone says " I saw five coyotes out here this morning".
That's the beauty of wildlife I guess.

April 2016 SPRING          Water in them reservoirs!  Many Dams letting water loose, Shasta way up!
Folsom, Oroville up!   Snow in the mountains!
“Drought is not over, but nature just landed a severe blow.”

The swainson hawks have returned!  I am seeing almost all of the usual suspects flying about. It’s going to be a great summer!
             Where did all the burrowing owls go? The burrowing owl population seems to be tanking badly in eastern CC County in my opinion. I will admit I could be wrong as groups I have followed for years may have just moved on over the hill. I keep looking for new colonies, attempting to locate lost colonies as well. Of an estimated fifteen plus colonies that I have photographed for many years, about a quarter or more of them are gone. I try to locate them in the immediate areas admitting they are known to move, in truth I can’t prove they are disappearing though I feel strongly and would surely bet they are declining rapidly in eastern CC County. Listed below are some possible reasons that may be related to the cause. I spoke with a representative of the burrowing owl conservation network and he advised they intend to perform a survey in the area and gather a count. I will later relate the results of their research. 

1-      The disking of area fields for fire prevention and weed abatement. This has been a long time issue which is undoubtedly a serious issue discussed several times even on this forum…
2-      Drought; I am no expert, but I wonder if insect / rodent population declines perhaps in late summer, has been effecting burrowing owl diet needs.

 3-   Over Grazing; this one may be off based, it is my thought. A technique in weed abatement is goat and sheep rental used for grazing in County flood control basins. It is a way to cut grass down in large areas while keeping costs down. Flood control basins in eastern CC County have been a preferred habitat location historically for burrowing owls. In flood control areas the heavy concentrations of animals grazing within a restricted area causes an unstable, trampled ground surface. In open ranching areas with cattle grazing, the effects are not nearly as bad because those areas receive nowhere near the same foot traffic per square feet. Some regional parks and water companies have used this practice for many years.

        It has been proven when mowers or weed eaters are used for weed abatement and fire prevention, burrowing owls will fly a short distance away until the danger has passed. When they return to their burrows the eggs, (and or) babies are intact and waiting. However, if the ground is disturbed and cave-ins occur, eggs and den collapse, then its game over for the little owls. I have been trying to find a study that’s relates to this practice and am asking informed folks that might have information relating to this to please let me know.  The grazing practice is not used in all flood control basins.
4- Use of poisons to control rodents, specifically those for ground squirrels as they are a living partner with the owls. This one provided from my friend Michael Marchiano...

*Photos include pictures of burrowing owls from our area, the white cat from the other end (Alameda side) of Los Vaqueros reservoir.  More raptors and other wildlife posted celebrating springtime in the bay area.

Burrowing owl near Grant St. in Brentwood, sad story as this small community lives under the side walk as the field gets disked yearly with no regards to species of special interest considerations...

Bay Area Local Wildlife March 2016

“Raptors in flight” I always have liked photographing raptors in flight. Each turn and angle presents different interesting views of these amazing birds.  One of my friends once told me those birds in flight are boring to view. I appreciated his honesty and opinion, though it never swayed me. To me the raptors are one of the greatest symbols of strength, freedom and confidence. They were the biggest key factor in drawing me in to loving nature and all of the animal species. They seem to look right through a person and are always making eye contact with anyone near them. Even driving down a country road if you look up at them on a utility pole or in a tree they are nearly always looking at you. Try it; it’s kind of interesting… I believe raptors are similar to our domestic cats in that each has its own wicked personality and when perched, have that same “way over confident appearance in their eyes” like they know something you don’t.

February is nearly gone, it is time to say good bye to the ferruginous hawks and get ready for the swainsons to return. Some rain returning would also be acceptable. This post will contain many photos of the winter time ferr’s and red tails who offer amazing color extremes. The collection of photos is dedicated to the raptors and their attitude for which we may never truly understand.
*Please click on a particular photo for a closer view...

ferruginous hawk (thanks Allen for help on ID) one of my favorites, this dark rust raptor was in the same tree for weeks near Bethel Island.

red tailed hawk (same hawk as above N/O Knightsen) just love the dark morph appearance.
