The hedgehog cactus out front is in bloom. The bees are taking advantage of that fact by browsing the colorful flowers. Click on the image to enlarge flower and bee.
I managed this shot from about 20 feet away from the cactus with the Canon SL1 using the 75-300mm telephoto lens. F7, ISO 100, 1/500 exposure, 300mm focal length. I sure like my new camera.
