Assorted Animal And Bird Photographs

Red Tailed Hawk

Although my favorite subjects to photograph are landscapes with mountains and lakes, I have been taking more photographs of wildlife recently. This is partly because of all the snow in the mountains and having to recover from anemia. Snowshoes and skis are out for now and hopefully I may have an opportunity for spring skiing if I continue to recover. Of course there are always the ‘drive byes’ where I can drive the rural roads that pass by and around our reservoirs on the San Joaquin River.

My subjects are partly determined by the lenses I have available to me. Until this year, I could not find a suitable long lens. I bought a used Canon 400 f4 D.O. lens and adapted it to my Sony. It has provided the ideal long lens especially when combined with the Canon 1.4X extender. This gives me a sharp 560mm lens for my Sony A7R2. This length and clarity make it suitable even for birds although I would not call it a good combination for BIF.

I generally find that using aperture priority and manual focus works fine. With an aperture of f8, the zone of focus is generous. The camera adjusts the shutter speed and ISO automatically. Sony has both focus magnification (5X and 12X) and focus peaking where the subject is highlighted when in focus. It is almost fool proof but consider the source.

There is a nice trail that follows Millerton Lake for about 2 miles to a place called Winchell Cove. The trail starts about 2 miles from the entrance on the Fresno County side of the lake. The trail is fairly flat with gentle rollers along the way. It has become one of my favorite winter walks. There is rarely a day when I don’t see an eagle or hawk.

I have learned to live within my new limitations and make the best of the restrictions.

Cardiac Stents, Dual Antiplatelet Therapy And Anemia


Dale Matson

In December of 2016 I had two Drug Eluting Stents (DES) placed in a coronary artery.
The standard protocol after DES is dual antiplatelet therapy. In my case this meant Plavix and aspirin. The reason for this is to prevent a clot from forming in the stents. The preferred standard of care in the United States is one year on DES and longer if there is no bleeding. How much longer is still being evaluated.
The problem for me was I had three ulcers that I was unaware of and on January 1st I began to notice black stools, which is an indication of a GI bleed. I was hospitalized and the following day an endoscopy was performed and the ulcers were cauterized. Thankfully this stopped the bleeding but not before my hemoglobin dropped to 7 because I lost half my blood volume.
The GI doctor prescribed daily doses of a liquid antacid and protein pump inhibitor to control the acid in my stomach and reduce the chance of a future bleed. The decision was made at the hospital not to give me an infusion of blood even though my hemoglobin level warranted it. The current thinking is that it is safer to let the patient build back their blood numbers without the possible problems that can accompany a transfusion.
I was sent home under this circumstance and had previously been prescribed Lipitor, a statin drug. Lipitor is prescribed for lowering cholesterol and reducing inflammation but the side effects for me were unacceptable with insomnia and loss of libido. Additionally statin drugs also are blood thinners.
I am 72 years old and don’t even want to talk about the possible other side effects of statin drugs for older people.
I had a prior bout with anemia because of prolonged bleeding from a surgical procedure a few years ago and learned how to raise my iron levels with iron rich foods and iron supplements. I also used a private testing lab to regularly check the progress of my anemia.
I began the same regimen but this time I was making very little progress. My hemoglobin, hematocrit and iron saturation were very low and climbing only slowly. I began to wonder about this and talked with my primary care physician. His comment was that the blood thinners and antacids were reducing the iron uptake in my system. He suggested an iron infusion but I am concerned about this because there is essentially no literature out there saying that iron infusions are safe for patients with stents.
I have read considerable literature about optimum duration of dual antiplatelet therapy for DES. In Europe, the standard is 6 months. As I understand the research on this, it claims there is not a significant difference in stent thrombosis with patients who stop dual platelet therapy after 6 months and those who stop after one year.
My GI doctor told me I could bleed again and this weighs heavily on my mind. It is the double-edged sword of the risk of bleeding verses the risk of a clot in my stents. It is not easy to live with and I wonder if some of the heart attacks in the stent research were stress related. It would simply be devastating to bleed again and lose what little progress I have made with my anemia that is a daily burden and an increased risk factor.
I know that my cardiologist, because of the U.S. standard of practice, would not be allowed to tell me to stop the dual antiplatelet therapy at 6 months even though I am at risk for another severe bleed. However, I will do what is necessary to maintain my quality of life. I have seen more than one piece of research from Europe that states that current generation DES are much safer than the first generation. The fact is that when there is a high bleeding risk the duration of the dual antiplatelet therapy should strongly evaluated. In some studies after one year the risk of bleeding increases as the risk of a stent thrombosis decreases.
I have not included citations of the research I have discussed, which can easily be found on an Internet search. Additionally, I am a layperson not making recommendations to anyone else. I am merely stating the difficulties I face and the decisions I have to consider. I know this however. It is important to be an informed consumer of medical services and that it is the individual patient who can and must be their own advocate and final decider.
I think there are a great number of folks out there who are in the same situation and I hope this article provides some clarity. What are your thoughts?

Buzzard’s Roost Trail At Millerton Lake

Hike Route Ambit 2 Download To Movescount



This trail is 1.2 miles total out and back with 532’ of elevation gain outbound from the trailhead. This is a steep trail. To get there from the Fresno CA area, you take Highway 206 out of the town of Friant and drive over the bridge that crosses the San Joaquin River/Millerton dam outlet. You turn right at the stop sign and go around to the Madera side of Millerton Lake. There is an entrance to the lake and a fee pay booth. Continue driving untill you see the trailhead sign on the left and Buzzard’s Roost pull out on the right for picnicking. That is where I parked and crossed the road to the trailhead.

This is a good time of year for this hike while there are no mosquitos, cooler temperatures, and a lovely seasonal creek to your left with a waterfall as you ascend. There is a sign at the trailhead warning about poison oak. The best prevention is to know what it looks like, stay on the trail and to take a shower using “”Technu” skin scrub at home immediately when you return if you believe you came in contact. If so, immediately wash your hiking clothes also. Poison Oak generally does not grow above about 6,000’ but Buzzard’s Roost is only about 1,083’ in elevation.

If you want a good view of the main part of Millerton Lake and are fit enough to make the climb, this is one of the best spots. There were several buzzards and crows that circled above me as I climbed. I did not take it personally since the name of the location was not accidental.

Keep an eye out for eagles, hawks and Osprey who also like to ride the updrafts created by the cliffs surrounding the lake. The top is a great place for a lunch. From Buzzard’s Roost you can see the “Big Bend” section of the lake, Winchell Cove across the lake, Winchell Point, The ‘Glass House which sits out on a peninsula with it’s resident Bald Eagle nest. You can also see the snow covered mountains. You can see Pincushion Mountain (about 1,350’ in elevation). That is another nice perspective, which can be reached via the San Joaquin River Trail at the end of Sky Harbor Road on the Fresno County side of the lake off Millerton Road. Sky Harbor Road is located just before the Table Mountain Casino and requires a 6 mile drive to the Finegold day use area where it dead ends. The San Joaquin River Trail begins in the day area and is also a steep climb.

I used a Sony A7R2 with a Batis 85mm 1.8 and an Adapted Canon 400 f4

Woodward Park Fresno, California The MacMichael Loop Trail

Woodward Park Fresno, California

The MacMichael Loop Trail

Many mornings on my daily walks with my Airedale Susie I head for the MacMichael Loop in the lower section of Woodward Park. Much of the 1.5-mile loop follows closely along the San Joaquin River as it flows through the north section of the park. The river also is the boundary between Fresno County to the south and Madera County to the south. Before Friant Dam was constructed, this was part of an annual flood plain.
As of this writing, the San Joaquin is about as high, wide and fast as I have ever seen it during my 25 years in Fresno. I have included a video clip of the river in my morning photos with my Sony RXIR.
As of this date (03-07-17) The Fresno Bee indicates Millerton Lake at 74% capacity, inflow at 5,942 cubic feet per second and combined outflow (San Joaquin River, Friant Kern Canal and Madera Canal) at 10,755 cubic feet per second. So, about twice the inflow is being released to accommodate anticipated future inflow because of lack of storage upstream.
In the early mornings, as the sun is coming up one can see the outline of the Sierra Nevada Mountains to the east. There can be varying degrees of fog in this lower area year round but fog is guaranteed in the winter season. This brings with it a rather mystical feel as you walk in the silence of the morning hours. It is usually about five degrees cooler down below year round in the early morning and in the summer runners appreciate that.
Sometimes you can see the distant headlamps of hikers and runners as they also travel the  loop trail. Susie insists on causing a commotion as other dogs pass by. This cannot be trained out of an Airedale. It is part of their nature. At times she will become beside herself because she is aware of other creatures in the area. We have seen Bobcats, lots of Coyotes and Deer, Eagles, Owls, Geese, Great Blue Herons, Egrets, Ducks and Osprey along the river and once a shadowy blur of a mountain lion passing out of sight into the fog. My headlamp will often catch the glow of eyes in the dark and it is somewhat disconcerting to see several pairs of what I know are Coyotes sizing us up. I am thankful Susie is on the leash.
Although there are some sections where there is obsessively redundant and annoying fencing, the foggy views are wonderful and ever changing. On the return toward home I we usually head up to the ponds where hopeful fishermen are patiently waiting to land a planted trout.

I have written previously about Woodward Park, which has several other venues to recommend it.  If you want to find out additional information just type “Woodward Park” in the Mid Sierra Musings search box or ‘Google’ the name.
