Why did you make your choice? <\/p>\n<h3>In the Last Blog Post<\/h3>\n<p>Everyone who commented liked either #2, the vulture taking flight with the grass background, or #4 the Cattle Egret with the hornworm caterpillar. My favorite was #2 for very nice takeoff pose and the sweet green background. <\/p>\n<h3>Summary<\/h3>\n<p>Today\u2019s blog post documents an exciting 15\u00bd-minute Western Cattle Egret session, highlighting how 20 quick vehicle repositionings yielded 600+ frames in an 11-minute, 53-second shooting window. It incorporates tactical field advice on working at 1200mm on the BLUBB for a low perspective, alongside a strategic gear swap to the handheld 600mm f\/6.3 for flight and action, plus tips for creating pleasing compositions with images featuring multiple subjects.<\/p>\n<p>This post also features a comprehensive technical breakdown comparing the Sony a7R VI\u2019s AI-driven autofocus to the a1 II, as well as the sensor\u2019s \u201cPixel Math\u201d \u2014 explaining how a 66MP file\u2019s 32% increase in file size translates to a 15.55% increase in resolution over 50MP bodies. Post-processing strategies cover both Eye Doctor and bill clean-up tips. Lastly, the text integrates natural history background on Western Cattle Egret (<em>Ardea ibis<\/em>), its foraging habits, <em>Larra bicolor<\/em> (parasitoid wasps), and Florida\u2019s native and invasive mole cricket populations.<\/p>\n<p>Be sure to stay tuned: over the next week or so, an upcoming post will take a deep dive into the shortcomings of the a7R VI for bird photography \u2014 along with the technical explanations that back up those findings, revealing exactly why the a7R VI costs $2,500 less than the a-1 ii. Promise.<\/p>\n<h3>Gemini<\/h3>\n<p>General information, copy editing, re-crafting, technical refinement, and formatting for this blog post were assisted by Gemini AI.<\/p>\n<h3>What&#8217;s Up?<\/h3>\n<p>My long-lost brother from another mother, Bob Eastman, drove 1,480 miles from Necedah, Wisconsin, to Indian Lake Estates in just two days! He arrived on Saturday evening around 8:30 p.m. He mentioned that the drive was an easy one overall, except for navigating around Atlanta, which he described as &#8220;hell on earth.&#8221;<\/p>\n<p>The forecast for Sunday morning called for rain, but we headed down to the lake early anyway. Our best find and most fun came from a pair of adult Sandhill Cranes nestled down in the grass resting. They were beyond cooperative and never stood up even when we stepped out of my SUV to photograph them from a lower perspective. For most of the session, I used the 600mm f\/4 (handheld!) paired with the Sony a7R VI. I was forced to handhold using the knee-pod technique because I inadvertently left my tripod in the garage . Of course, it did not begin raining until the afternoon. <\/p>\n<p>The a7R VI\u2019s 66MP raw files continue to amaze me. In several weeks (or possibly less), I will be offering my settings for the Sony a7R VI, along with a Buttons and Dials Guide and a detailed INFO sheet \u2014 free to anyone who purchases this new camera body using one of my affiliate links. Two folks have already jumped on the a7R VI bandwagon! In the meantime, if you have already purchased the camera using one of my links, email me your receipt to receive my current CAMSET.DAT file. I am really enjoying this new camera body and will be sharing plenty more about it here soon. Including potentially problematic issues. <\/p>\n<p>The same offer applies if you have purchased the featherweight Sony FE 600mm f\/6.3 GM OSS lens through one of my links. On Saturday, I finished the BAA 600mm f\/6.3 Lens Guide and sent the PDF to everyone who earned their free copy by using a BAA affiliate link. My tips on dealing with temporary AF blindness with this lens are easily worth the price of admission. In fact, I am considering publishing a small standalone guide on handling temporary AF blindness across all camera systems.<\/p>\n<p>Today is Monday, November 2, 2026. It has been raining hard all night, and since 3:00am it has poured monsoon-like with high winds, thunder, and lightning. Most readers will not be shocked to learn that Bob and I will still be heading down to the lake in hopes of finding something \u2014 anything \u2014 to photograph! Today marks my 49th consecutive morning of bird photography; I haven&#8217;t missed a single day out in the field since returning from Long Island on Sunday, September 13.<\/p>\n<p>Later today, I will be finishing work on a 400\u2013800mm YouTube video, optimizing more a7R VI and 600mm f\/6.3 images, and continuing my deep dive into the compromises that serious bird photographers face with the a7R VI&#8217;s lower price tag. As usual, Arash Hazeghi has been incredibly helpful by explaining the technical differences between this new camera body and the flagship a1-series models.

Handholding even the bare 600mm f\/4 for flight for more than a few moments is out of the question for me these days. I botched the first opportunity because I failed to remove the BLUBB from the door frame \u2014 the big beanbag got in the way as I tried to pan with the bird.<\/p>\n<p>That done, I had some success, though I\u2019m generally not a fan of a quasi-horizon line bisecting the subject.<\/p>\n<p>Gear note: The differences in size, weight, and cost between the 600mm f\/4 GM and the 600mm f\/6.3 GM are nothing short of astronomical. When Bob picked up my new featherweight 600, he asked &#8220;What lens is this?&#8221; When I told him that it was the small, new, lightweight 600 he was flabbergasted. &#8220;No way!&#8221; were his exact words. <\/p>\n<p>Image Optimization Note: Because the bird\u2019s head was angled slightly away, I moved the pupil back within the eye using a Quick Mask, refined it with a Regular Layer Mask, and cleaned up the edges with the Clone Stamp Tool.<\/p>\n<table>\n<tr>\n<td>\n<p><center>ngg_shortcode_2_placeholder<\/center><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>Be sure to click on the image to see the larger, inexplicably sharper high-res version. <\/p>\n<h2><strong>#2A: The AF point for the <em>Western Cattle Egret in flight over the North Field image<\/em><br \/>\nImage copyright 2026 Arthur Morris\/BIRDS AS ART<strong<\/h2>\n<p><iframe loading=\"lazy\" width=\"468\" scrolling=\"no\" height=\"60\" frameborder=\"0\" style=\"border:none;\" border=\"0\" src=\"https:\/\/mer54715.datafeedfile.com\/widget\/aff_widget_prdt_generate-2.0.php?aff_num=7226&#038;aff_net=1&#038;size=468x60&#038;mode=m&#038;bucket_num=11730&#038;link_target=y&#038;sid=\" marginheight=\"0\" marginwidth=\"0\"><\/p>\n<p>Your browser does not support iFrame.<\/p>\n<p><\/iframe><\/p>\n<\/td>\n<\/tr>\n<\/table>\n<h3>A7R VI AF<\/h3>\n<p>The a7R VI AF system performed perfectly throughout the entire cattle egret session. Aside from that botched fly-by opportunity, the AF nailed the eye in every single frame \u2014 and even better, every image was tack-sharp on the eye.<\/p>\n<p>Although I\u2019ve had the new camera body for less than a week, I feel confident making a few initial observations:<\/p>\n<p>Eye-Tracking Performance: In terms of initial eye-tracking acquisition, the a7R VI seems to perform slightly better overall than the a1 II about 98% of the time \u2014 it seems as though Sony\u2019s AI subject-recognition training has been noticeably improved. However, I have encountered a few rare instances where the a7R VI inexplicably struggled with focus in situations that the a1 II would have handled effortlessly.<\/p>\n<p>Sharpness &#038; Sequence Consistency: When shooting longer sequences of both static and flying birds, tracking sharpness with the VI is not quite as consistently spot-on as it is with the a1 II. Keep in mind that the a1 II processes 120 AF calculations per second compared to 60 on the a7R VI. Theoretically, this difference should show up most when birds are flying directly toward the camera.<\/p>\n<p>Please note:<\/p>\n<p>Lighting: In full sun on a clear day, both eye-tracking and critical sharpness with the handheld 600mm f\/6.3 and the a7R VI were virtually flawless.<\/p>\n<p>Focus Limiter: Setting the Focus Range Limiter switch to NOT FULL made initial target acquisition virtually instantaneous.<\/p>\n<p>Handling: The compact size and light weight of the 600mm f\/6.3 made handholding and framing effortless across all situations. It did not matter whether bird was static, walking or running, or in flight.<\/p>\n<table>\n<tr>\n<td>\n<p><center>ngg_shortcode_3_placeholder<\/center><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>This image was created on 31 October 2026 down by the lake near my home.

Their diet in North America consists overwhelmingly of land-dwelling invertebrates, supplemented by small terrestrial vertebrates:<\/p>\n<p>1. Primary Diet &#8212; Insects &#038; Invertebrates: grasshoppers, crickets, and locusts make up the single largest portion of their diet. Horse flies, deer flies, stable flies, and horn flies. They frequently snatch these directly from the air, low vegetation, or off the hides and legs of grazing livestock. Beetles &#038; Caterpillars: ground beetles, dung beetles, armyworms, and moth larvae flushed out of the turf. Other Invertebrates: spiders, dragonflies, earthworms, and occasionally ticks.<\/p>\n<p>2. Secondary Diet: Small Vertebrates &#8212; when opportunities arise \u2014 especially in mowed fields or near water, they may prey on small land animals including Amphibians: leopard frogs, cricket frogs, chorus frogs, and toadlets, Reptiles: small lizards (anoles, skinks) and small snakes. Mammals: nestling rodents, such as field mice or voles. On rare occasions, they have been documented taking small nestlings or the eggs of ground-nesting birds.<\/p>\n<p>To that list we can definitely add wasps. It is likely that the wasp in the photo is Larra bicolor, a parasitoid wasp native to South America. It was introduced into Florida as a biological pest control of invasive mole crickets, a favorite food of the Sandhill Cranes. I learned that there are three non-native species of mole cricket in Florida and one native species, Northern Mole Cricket.<\/p>\n<p>Even though the three invasive species are major pests for sod farms and homeowners, they are an incredible, high-protein food source for local birds. Sandhill Crane, Crested Caracara, White Ibis, crows, and American Robins will spend hours probing and digging up pasture turf to devour them!<\/p>\n<h3>Making Hay<\/h3>\n<p>You might say I made hay while the Cattle Egrets foraged and the light held\u2014all of today\u2019s featured images were created in a mere 11 minutes and 53 seconds! Over the course of that quick 15\u00bd-minute session, I moved my vehicle about 20 times and created more than 600 frames. When the action is happening and the light is right, you have to strike while the iron is hot.  <\/p>\n<table>\n<tr>\n<td>\n<p><center>ngg_shortcode_5_placeholder<\/center><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<h2><strong>#4A: The 100% crop of the <em>Western Cattle Egret with wasp in bill<\/em> image<br \/>\nImage copyright 2026 Arthur Morris\/BIRDS AS ART<\/strong><\/h2>\n<p>Be sure to click on the image to see the larger, inexplicably sharper high-res version. <\/p>\n<p><iframe loading=\"lazy\" width=\"468\" scrolling=\"no\" height=\"60\" frameborder=\"0\" style=\"border:none;\" border=\"0\" src=\"https:\/\/mer54715.datafeedfile.com\/widget\/aff_widget_prdt_generate-2.0.php?aff_num=7226&#038;aff_net=1&#038;size=468x60&#038;mode=m&#038;bucket_num=11730&#038;link_target=y&#038;sid=\" marginheight=\"0\" marginwidth=\"0\"><\/p>\n<p>Your browser does not support iFrame.<\/p>\n<p><\/iframe><\/p>\n<\/td>\n<\/tr>\n<\/table>\n<h3>The A7R VI Pixel Math<\/h3>\n<p>Full-frame a7R VI files measure 9984 \u00d7 6656 pixels (66,453,504 pixels or ~66MP), compared to 50MP on the a-1 and the a-1 II. While total pixel count is up 32%, that translates to a 15.55% increase in resolution. (Special thanks to brilliant friends Arash Hazeghi and Patrick Sparkman for helping clarify the math!)<\/p>\n<p>Any way you look at it, the cropping power of the a7R VI sensor is remarkable. In the frame that captured the wasp best, the bird&#8217;s nictitating membrane was covering the forward third of the eye. I substituted the eye from the preceding frame, then gave the bill a much-needed touch-up using my regular cadre of Photoshop clean-up tools and techniques: the Patch Tool, the Remove Tool, Content Aware Fill, and rarely, the Clone Stamp Tool.  <\/p>\n<h3>Typos<\/h3>\n<p>With all blog posts, feel free to <a href=\"mailto:samandmayasgrandpa@att.net\">e-mail<\/a><\/center> or to leave a comment regarding any typos or errors.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Your Call <\/p>\n<p>Which of today\u2019s featured images do you like best?
