Lol, the feared mockingbird leaves a trail of domination across the entire country. That is one fearless bird and aggressive mother hen !
How is it that a 2 pound bird can frighten half the mammals on earth.

Yesterday was bright but had a thin layer of cloud cover. Direct bold sun presents challenges. Filters probably fix glare and high heat effects but me not up on filters. In particular waiting for an overcast day to try out the 1920mm digital zoom and was well pleased with the results. So easy to get sharp macros hand held... Bare in mind this is an old digital zoom, say 7 to 10 years old. New tech likely to perform better. a young beadie eyed praying mantis. Easy subject. Full zoom, no crop, 1920mm Half zoom, call it 1000mm yea, I am looking at YOU and I will eat you live. Probably the cockiest insect on earth.(I was messing with him) Note ant in danger. Highly predatory, forgot name Closer at about 1500mm Full 1920mm zoom from 5 feet away ! so easy Dragonfly shots dead crisp in this lower light. ISO 400, 1/320 second, f10 all at 1000mm digital zoom. 1000 might be the sharpest... 1500mm, closer, same settings as above, same fly. Note rotated head... full blast 1920mm zoom f10 gave deeper focus range than the 'AUTO' chosen f4.5 Too much narcotic nectar because he is dead as a hammer ?

From a salt-of-the-earth farming community populated by good ole boys to destiny #1 for well-to-do African Americans here Tela. And some very entitled and racially arrogant folks at that. Talk about culture shock lol. I came from urban Atlanta and am used to the complexity of mixed races. But many of the locals were none too happy. Another one that never got much airtime, Jim. apnews.com/article/Atlanta-race-massacre-9d738b6fa08d26ec91adfcd8fff30f7f

I think these events should be remembered, but I question the timing of a media campaign, at this moment, when race relations are simmering. I absolutely believe that true racism is dying. I see no point in stoking the flames when the perpetrators are long dead.

The 8th grade(and other grades) social studies curriculum focuses on such past events of the social eras like the New South Era for example: SS8H7 Evaluate key political, social, and economic changes that occurred in Georgia and the south during the New South Era: a. Identify the ways individuals, groups, and events attempted to shape the New South; include the Bourbon Triumvirate, Henry Grady, International Cotton Expositions, and Tom Watson and the Populists. b. Analyze how rights were denied to African Americans or Blacks through Jim Crow laws, Plessy v. Ferguson, disenfranchisement, and racial violence, including the 1906 Atlanta Riot. c. Explain the roles of Booker T. Washington, W. E. B. DuBois, and Alonzo Herndon in advancement of the rights of African Americans or Blacks in the New South Era. d. Examine antisemitism and the resistance to racial equality exemplified in the Leo Frank case. Let's hope education helps correct race issues... Don't forget about New York city's assistance in the slave trade and slave abuse. rockjunquie Such issues not limited to the south...: www.mnys.org/was-there-slavery-in-new-york-city--new-york-state/

your shots are going to start effecting my dreams jeez! It took about 15 relaxed minutes to get those shots Ed. It is the powerful digital zoom that makes that camera so diverse. Just be careful how you pick it up, it has so many buttons. If you happen to touch one of those buttons it is difficult to return it to your desired settings. The Lumix FZ2500 camera may work for the Mohs. Just be aware that the zoom extension is delicate and vulnerable to dirt/sand particles. It is NOT a good camera for harsh conditions and the Moh's vertical butte climbs. That rugged waterproof Olympus(TG?) point and shoot has an enclosed zoom extension which limits the amount of travel and therefore the reduced zoom capability. A trade-off for performance verses durability.

I gave all my aquatic plants away to clients except the Sarracenia. Glad I kept them ! There is far more dragonflies buzzing 1500 sq ft of carnivorous plants than 100,000 sq ft of shallow lily ponds and emergent plants. Goes to show how plant diversity makes habitats.

Way cool - love that you caught the butterfly tongue. The dragonflies are always a pleasure. Look at all those muscles on their back. Powerful The wings look almost drawn in, in the top photo. So delicate & lacy. Good adventuring in your backyard ! Patty

Hey jamesp a slight thread hijack again... I went to the dentist yesterday- they rescheduled me sooner because of the increase in pain. I was in the chair for 3 hours! He found a "pulp stone" which I had never heard of and instead of the usual 2 canals, he found a hidden one. I have always claimed that my teeth are sensitive and NEVER have ice in my drinks. Now I know why.
Absolutely no pain. This guy is a keeper.

So delicate & lacy. Good adventuring in your backyard ! Patty If country could reproduce a war machine that few as articulately as a dragonfly they would rule. The design of that bug is off the chart. Bug muscle is incredibly strong for it's volume and weight. A computer that could send and receive control signals on such a level would be substantial in size and weight. "Most insects have multifaceted eyes—house flies, for example, have about 6,000 eye facets that give them a panoramic view of their surroundings. It’s the reason their eyes look like honeycombs up close. But with 30,000 individual facets, dragonflies blow them—and every other insect—completely out of the water."

Holding open that long is just plain painful in itself. Sounds like the episode is complete and you have a tooth that will last. I never heard of a pulp stone.

Dragonfly Eyes Are Incredibly Advanced
Most insects have multifaceted eyes—house flies, for example, have about 6,000 eye facets that give them a panoramic view of their surroundings. It’s the reason their eyes look like honeycombs up close. But with 30,000 individual facets, dragonflies blow them—and every other insect—completely out of the water. Each facet, or ommatidia, creates its own image, and the dragonfly brain has eight pairs of descending visual neurons to compile those thousands of images into one picture.And it gets even crazier; dragonflies have visual senses that would be considered superpowers by any human standards. Human eyes have three opsins—proteins that sense light—giving us a color range of red, green, and blue (one for each opsin). Dragonfly eyes can have four or five opsins, allowing them to perceive the normal color spectrum, along with UV light and the plane of light polarization (the effect you get with polarized sunglasses). This is believed to help them navigate and reduce the sun’s glare on a body of water. These eyes are also the reason….
Multi-Directional Viewing
Fact: They Can See In All Directions The massive bulbous eyes of a dragonfly wrap around its head like an astronaut’s helmet, giving it a 360 degree view of the world. As dragonfly researcher Dr. R. M. Olberg put it, “They can see you when they’re flying towards you, and they can see you when they’re flying away.” Obviously, this is a valuable tool for escaping predators. The above video (4) shows a dragonfly escaping the clutches of a frog who lunges at it from behind and underneath—in most insects, that’s their blind spot. Dragonflies themselves take advantage of that when they intercept their own prey—they attack from behind and underneath. But dragonflies don’t have blind spots, and they’re notoriously hard to catch.Okay, one more fact about dragonfly eyes before moving on. When they hunt, the compound eyes of a dragonfly allow it to sort of “section off” its visual field, like a grid. Keeping their prey in the same section of the grid helps with that incredible accuracy when they intercept something mid-flight.Here’s a human comparison—draw a grid on the windshield of your car and pick a target. A goat, let’s say. Aim the car so that the goat is in one square of the grid. Now drive towards the goat, keeping it within the same square. The goat will get larger as the gap closes, but your angle in relation to it will not change, even if it’s moving.
Swarms
The truth is, there’s an even deeper level of crazy at work here, as Dr. S.D. Wiederman discovered when he began studying the way Emerald dragonflies select their prey. Curious about the way dragonflies hunt, Dr. Wiederman and his team placed a nano-electrode inside the visual processing neuron of a dragonfly. They then positioned the “subject” in front of a TV monitor with two moving objects.In simple nervous systems, multiple objects tend to fade out; the insect can’t handle the attention multitasking. But dragonflies have the ability to switch their attention between objects at will. Under observation, the dragonfly focused first on one object, then shifted to watch the second, then shifted back to the first again, never losing track of where they were. This selective attention span allows the dragonfly to single out one target in a swarm, then zero in on it exclusively—while remaining aware of the the rest of the swarm to avoid a collision.

I ran into a guy over on Ganoksin a number of years ago -
Most talented man- he's a fine jeweler by trade & has a hell of an imagination & creates art as well.
His art is a combo of fine jewelry & machine work.
Here's his dragonfly fighter :
Check out all the other sculptures as well Jim, jamespHe had a going thread on the jewelry forum about the war between the insects and the dinosaurs .
Pretty cool .

OMG Those are intergalactic liveoakMellow Mushroom does full scale steel statues of welded car parts that keep me hypnotized. In this case fine Swiss watch components, amazing. Thanks for sharing, am blasted away. PS I despise his skill of leaving no solder stains. How does he do that ?

Hans is a genius at making these contraptions. He is one talented man! I have been watching him create these things for years. Perhaps my favorite is the Ptero Bow that actually works. gemfeller is friends with Hans. He also has a site with carving tutorials on it. An amazing jeweler as well.
