I retired in 2005 after 40 years of research and teaching at the University of Alabama in Birmingham (24 years), the University of Pennsylvania (8 years) and the Baylor College of Medicine (8 years). Photography is my retirement hobby.

Nature photography, especially bird photography, combines a number of things that I really enjoy: bird-watching, being outdoors, photography, travel, messing about with computers, and learning new skills and concepts.  I now spend much of my time engaged in these activities.

David Sibley in the preface to The Sibley Guide to Birds wrote "Birds are beautiful, in spectacular as well as subtle ways; their colors, shapes, actions, and sounds are among the most aesthetically pleasing in nature."  My goal is to acquire images that capture the beauty and uniqueness of selected species as well as images that highlight the engaging behaviors the birds exhibit.

Fourteen posts with photos and text related to a 2020 safari in Tanzania have been presented here previously. The supply of images depicting the amazing wildlife we observed during the trip was not depleted by those presentations, but entries about other topics appeared instead. In an effort to preserve memories of the trip, I recently reviewed the photos I saved from the trip and generated five additional blog entries.

A foggy morning at the Black Point Wildlife Drive at Merritt Island NWR

/

The Black Point Wildlife Drive is a seven mile long, one-way dirt road through part of the Merritt Island NWR near Titusville, Florida. On January 2, 2023, following the schedule I had established on previous days, I arrived at one of the pools of water adjacent to a segment of the drive about 30 minutes before sunrise. The first three photos illustrate the conditions present at Merritt that morning. The first photo was taken about 30 minutes before sunrise. The second was taken five minutes later at a different location. The third photo is of the photographers I was following at the end of my two-hour-long first loop around the Black Point drive.

Photo illustrating the light conditions at one part of the Wildlife drive about 30 min before sunrise.

Photo illustrating the light conditions at a different part of the Wildlife drive about 5 minutes later.

The fog was still present when I finished my first loop around the trail two hours after beginning the drive.

As illustrated here, the initial photos I took of the birds feeding at the pool of water where I had stopped were nondescript. Taken in the fog when the light levels were low, they were lacking in detail and color. Nonetheless, I found it interesting that, because of the stillness of the water and the distribution of the available light in the fog, the reflection of the bird in the water had almost as much detail as that seen in the bird itself.

Sometimes the photos from that morning contained the images of two or more birds and their reflections. I liked the effect of some of these shots enough that, subsequently, I have spent some of my time experimenting with ways to photographically exploit the detail that is present in the reflections when light levels are greater. I will post results of this experimentation later.

The fog conditions varied as time and location changed. Some images generated (for me) a mystical feeling. This photo and the next one are examples of those that did so.

Reddish Egret and Roseate Spoonbills feeding on a foggy morning at the Merritt Island NWR.

The last five images are of a Great Egret. The bird appeared to emerge from the screen when I first saw them. The white feathers of the bird seemed to collect almost all of the available light and the relative absence of light in the surrounding water creates an illusory vignette.

I am intrigued by the photographic effects of fog. I was inspired to read more about it on the web and found an informative article on The Canadian Nature Photographer web page. Take a look.

Merritt Island NWR (Titusville, FL) December 9, 2022

/

I arrived at the entrance to the Black Point Wildlife Drive about 30 minutes before sunrise. On visits earlier in the week, I had noted that Roseate Spoonbills and other wading birds sometimes spend the night at the pool of water near the entrance. When I arrived on this morning, not as many birds were there as I had observed previously, and many of the ones present flew to other locations during the pre-sunrise low light levels.

High ISO, low shutter speed image of some of the birds at the pool near the entrance to the wildlife drive.

As the sun reached the top of the trees behind the pool of water, the reflection of the trees was brighter than the image and reflection of the out of focus Reddish Egret.

When the sun was a little higher, the light on the Roseate Spoonbills produced dramatic images . . .

and it was easier to get good focus on the darker, now actively feeding, Reddish Egret.

Another example.

This Merritt Island trio was the visual equivalent of music to my ears.

Now approximately 20 minutes after sunrise, as illustrated in this and the following four photos, most of the birds begin to leave the pool near the entrance to the wildlife drive.

This Wilson’s Snipe, and a yellowlegs continued to feed on the distant perimeter of the pool after the larger wading birds departed.

An uncropped image of two Wilson’s Snipe and their refections captured with the OM-1 camera and the 150-400 mm lens with the built-in 1.25 teleconverter engaged. I was unaware of the out of focus bird in fight when taking the shot.

The chapters of Volume 12 of The History of Neuroscience in Autobiography published by the Society for Neuroscience and edited by Tom Albright and Larry R. Squire are freely accessible on the SfN website: https://www.sfn.org/about/history-of-neuroscience/autobiographical-chapters

It was an honor to be invited to contribute a chapter to this volume. The autobiographies of the authors of scientific papers I read as a graduate student, ones that influenced the direction of my scientific career, are found in early volumes of this collection. A pdf of my chapter in Volume 12 can be downloaded by using this link: https://tinyurl.com/4rhr5mu2

Writing the chapter was one of the projects that occupied my time while living alone in my “cave” during the early days of the COVID-19 pandemic. Jennifer Groh and Shari Hatch provided helpful comments on an early version of the chapter.

Fall colors in Colorado

/

I just returned from a photography trip to the Gunnison/Crested Butte region of Colorado. I am still sorting and culling the images. Three photos that captured my attention while doing so are shown below.

The first two photos depict the reflection of a nearby mountain range in the Slate River. The photos were taken near highway 734 to the north and west of Crested Butte.

The Aspen leaves floating in the water partially obscure the reflections of the trunks of four Aspen trees (focus your attention on the gray areas).

Pawnee National Grassland

/

I decided to visit the Pawnee National Grassland on Wednesday It is about a 90 minute drive from my condo. It was not my most productive photography outing, but I enjoyed being there and seeing, from a greater distance than I desired, flocks of sparrows and other grassland birds. I saw a fair number of birds, but not so many in my viewfinder. How can I rationalize the failure to capture a greater number of interesting photos? I could blame it on the increase in traffic in the grasslands, but I would need to suppress the memory of what I actually experienced (see photo below).

Or … I could argue that the birds would not let me get close because of the decrease in useable habitat attributable to the marked increase of recent development in the area. But I would need to convince you that the developments in the area were recent.

And I would need to convince myself that the failure to capture some interesting images was not due to slow reflexes.

Perhaps I was expecting too much. It was windy and the birds were staying low in the grass most of the day.

The burrowing owls were not very active. One only peeked at me a few times.

Another one exposed most of its body but did not engage in any interesting behaviors.

I saw numerous McCown’s Longspurs hovering, but at a distance. This image is heavily cropped and over sharpened.

Decent exposure and sharpness on shots of a Brewer’s Sparrow taking flight, but ….

only the back of the head is visible.

This photo of a Rock Wren is o.k., but I wish it was perched on a rock.

This post is not a lament. Consider it a verification of the “Be Prepared” section of Mia McPherson’s blog post entitled So ya think ya want to be a bird photographer? LINK in which she has a section about being prepared to be frustrated. If you haven’t read this entry in her blog, you should.

I am eager to return to the Pawnee National Grassland. Capturing the hovering behavior of the McCown’s Longspurs is now on my bucket list.

Forgotten fotos found - Black Skimmer chase

I discovered these photos of a Black Skimmer chase while in the process of compiling favorite photos taken at birding spots near my former residence in Pensacola, Florida. The chase was observed on August 28, 2009 at Fort Pickens, Florida. Fort Pickens is one component of the Gulf Islands National Seashore. If my memory is correct, the skimmer with the minnow managed to evade the chaser and consume the catch.

David Sparks

I retired in 2005 after 40 years of research and teaching at the University of Alabama in Birmingham (24 years), the University of Pennsylvania (8 years) and the Baylor College of Medicine (8 years). Photography is my retirement hobby.

Nature photography, especially bird photography, combines a number of things that I really enjoy: bird-watching, being outdoors, photography, travel, messing about with computers, and learning new skills and concepts.  I now spend much of my time engaged in these activities.

David Sibley in the preface to The Sibley Guide to Birds wrote "Birds are beautiful, in spectacular as well as subtle ways; their colors, shapes, actions, and sounds are among the most aesthetically pleasing in nature."  My goal is to acquire images that capture the beauty and uniqueness of selected species as well as images that highlight the engaging behaviors the birds exhibit.
