in quante maniere può essere visto uno stesso soggetto ?
Il problema poi è sempre quello del rispetto...
California towhee
While this is a common rather dull bird in California and the photo is not stellar, I couldn't help but post this as it is a perfect demonstration of the phrase "jumping through hoops".
This male just got himself a nice snack as I was setting up my camera.
Taken with my non-macro zoom lens and 1.4x TC. I also set the camera to APS-C crop mode. The TC really helped with the shallow depth of field.
All up, I am quite pleased with the result.
It is surprisingly difficult to catch these ducklings in mid air as they go to dive. I estimate that it takes them < 1/4 second from start to when they are submerged.
My attempt at the "Flickr Friday" theme "Jump".
Shot with a Minolta "90 mm F 5.6" (copy) lens on a Canon EOS R5.
One of the commonest spiders you can find around the house is the zebra spider, Salticus scenicus. You can find it sitting on the wall or on a window-frame but it is not so easy to spot. It is a tiny spider with a body size that doesn't exceed 8 millimetres. The zebra spider belongs to the jumping spiders. It does not make a web but stalks its prey. It will use a silk thread as an anchor. When it spots an insect it will slowly try to approach it. Now and then when it is out of the victim's sight the zebra spider will run. When it is within reach it will jump and paralyse the prey with its venomous 'jaws'.
To be able to capture prey like this jumping spiders rely on superb eye sight. Their eyes are truly remarkable. The front pair is the most impressive. They can be regarded as the best eyes you can find in any arthropod. They work as a telephoto lens. The retina inside the eye can move in 3 dimensions enabling the spider to look in all directions and focus on a subject. When you approach a jumping spider it will position itself so it can observe you. The 6 other eyes are positioned around the head for a 360 degrees vision.
