He carried the 600 f\/4, and I carried the 70-200 II and a tripod. I had three TCs along for the ride. We walked three miles. For the first mile plus, we saw no birds. Then on the western shore of Lake Hancock, we came upon a big feeding spree of herons and egrets. Lots of wood Storks flew by. I tried a few silhouettes at 840mm, but the birds were very skittish &#8230; We walked out on the gazebo pier to get the sun behind us;  I had a few decent chances. The best of those led to the creation of the two versions of today&#8217;s featured image below. At about 8:15am, we headed back to the car via the circular path. For that last mile plus, we saw no birds. <\/p>\n<p>In the afternoon, I did some housework in preparation of giving away a ton of old cloths and enjoyed my 1\/2-mile slow swim. After dinner it was 20 minutes of rope flow practice. The ILE forecast for this morning is for partly cloudy with a gentle breeze from the south. That usually means clear and sunny. I will be heading down to the lake early hoping to work again with the new Sony 400mm f\/2.8 GM lens. Wherever you are and whatever you are doing, I hope that you too have a great day.

The 600mm f\/4 lenses with a 2X TC get you to 1200mm. Note: with Sony, creating sharp images at 1200mm is as close to child&#8217;s play as you can come. The 400mm f\/2.8 lenses with a 2X TC get you to 800mm. So, we are comparing 1200mm to 800mm. It would seem that the subject would be &#8220;only&#8221; 50% larger in the frame. But the relationship between the focal length and the size of the bird in the frame is not a linear one. It is a function of the square of the focal length:<\/p>\n<p>Eight squared is 64. Twelve squared is 144. 144\/64 = 2.25. Therefore, the size of the bird in the frame at 1200mm is 2 1\/4 times larger than the size of the bird in the frame at 800mm. Note that if you remove the TCs from the equation, the math remains the same. <\/p>\n<p>For the past three decades, I have been saying this: a longer, slower lens is a better choice for bird photography than a faster, shorter lens. You must also remember that lenses are tools. I am blessed to be able to own and use two of the best tools ever created for bird photography. Until I buy the farm, I can guarantee that I will continue making great images with both the 600mm f\/4 and the 400mm f\/2.8. But when you need the most reach, the 600s are the ticket. <\/p>\n<table>\n<tr>\n<td>\n<p><center>ngg_shortcode_1_placeholder<\/center><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>This, the same image, was created on 26 May 2022 at Circle Bar B Reserve in Lakeland, FL.

At times it will acquire and track the bird&#8217;s eye as seen in the screen capture above, and at times it will detect and track the bird&#8217;s face. Though that is less impressive, the images in either case are razor-sharp. <\/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<h2><strong> The BAA Middle of Florida Photographic Site Guide<\/strong><\/h2>\n<p>You can purchase your copy <a href=\"https:\/\/birdsasart-shop.com\/the-baa-middle-of-florida-photographic-site-guide\/\" rel=\"noopener noreferrer\" target=\"_blank\">here <\/a> in the BAA Online Store. <\/p>\n<\/td>\n<\/tr>\n<\/table>\n<h3>The BAA Middle of Florida Photographic Site Guide<\/h3>\n<h2>126 pages, 87 photographs by Joe Przybyla and Arthur Morris.<br \/>\nThe PDF for this e-Guide is an electronic download sent via e-mail.<\/p>\n<p>Purchase your copy <a href=\"https:\/\/birdsasart-shop.com\/the-baa-middle-of-florida-photographic-site-guide\/\" rel=\"noopener noreferrer\" target=\"_blank\">here <\/a> in the BAA Online Store.<\/h2>\n<p>I had thought about doing a guide to some of the great but little-known photo hotspots around central Florida for about a decade, but those plans never came to fruition. I met Joe online in the <a href=\"http:\/\/www.birdphotographers.net\/forums\/forumdisplay.php\/2-Avian\" rel=\"noopener noreferrer\" target=\"_blank\">Avian Forum<\/a> at <a href=\"http:\/\/www.birdphotographers.net\/forums\/content.php\" rel=\"noopener noreferrer\" target=\"_blank\">BirdPhotographer&#8217;s.Net<\/a> about two years ago. Joe&#8217;s photography has improved tremendously over the past few years; he credits the BAA blog, my books and PDFs, and his participation on BPN. The one thing that I learned right from the get-go about Joe is that he is a hard and tenacious worker, always striving to improve his skills and to grow his knowledge base. As he knew of more than a few good spots in central Florida, I broached the idea of us doing a photographic site guide that covered many of the little-known photographic hotspots from Brandon to Lakeland to Joe Overstreet Road to Indian Lake Estates (my Florida home for the past 20 years or so). After more than many, many dozens of hours of effort, The BIRDS AS ART Middle of Florida Photographic Site Guide is now a reality. Thanks to Joe&#8217;s wife Dottie for her review of our writing. We all learned once again that writing is a process, a back-and-forth process. All thanks to the white pelicans of Lakeland. Here are the locations that are detailed in this e-Guide:<\/p>\n<ul>\n<li><strong>Indian Lake Estates<\/strong>: Sandhills Cranes with chicks and colts, lots of vultures, and Ospreys up the kazoo!<\/li>\n<li><strong>Gatorland, Kissimmee<\/strong>: Learn to make great images of wading birds in a cluttered rookery.<\/li>\n<li><strong>The Brandon Rookery<\/strong>: Great for nesting Wood Storks, Great Egrets, and more.<\/li>\n<li><strong>Circle Bar B Reserve, Lakeland<\/strong>: Here you will find a great variety of avian subjects in a great variety of habitats.<\/li>\n<li><strong>Lake Morton, Lakeland<\/strong>: There are lots of silly tame birds here including and especially American White Pelican during the colder months.<\/li>\n<li><strong>Lake Mirror, Lakeland<\/strong>: Tame Anhingas, Limpkins, and a zillion White Ibises at times.<\/li>\n<li><strong>West Lake Parker, Lakeland<\/strong>: Here you will have a chance for two difficult birds, Snail Kite, and Purple Gallinule.<\/li>\n<li><strong>Joe Overstreet Road, Kenansville<\/strong>: Crested Caracara, meadowlarks, Loggerhead Shrike, and much more on the fenceposts and barbed wire. <\/li>\n<\/ul>\n<p>Each location includes a map, a detailed description of the best spots, best season, light and time of day instructions, the expected species, and an educational and inspirational gallery that is designed to open your eyes as to the possibilities.  <\/p>\n<p>You can purchase a copy <a href=\"https:\/\/birdsasart-shop.com\/the-baa-middle-of-florida-photographic-site-guide\/\" rel=\"noopener noreferrer\" target=\"_blank\">here <\/a> in the BAA Online Store.  <\/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>What&#8217;s Up? <\/p>\n<p>Jim and I made it early to the Circle Bar B Reserve in Lakeland.
