Afternoon at the Birdfeeders. Individual images in the slideshow are available in my PhotoShelter Gallery.

Contact me if you are interested in a Time-lapse Video of the Morning at the Birdfeeders. My setup for the birdfeeder images is a Nikon D850 camera and 200 mm f/2 VR lens set to take one image every 5 seconds over a 5 hour period (~3600 images). The new time-lapse video format is 720p (1080 x 720 pixels) and 1 frame/second. The length of the video is about 1 hour in a 1 GB MP4 file. The previous time-lapse videos of the birdfeeders were at 12 frames/second, and to be honest were too fast to identify the birds.

I went out with the DR Power Brush Mower to mow the wildflower meadows. Not much is blooming anymore, and the weeds including the invasive “mile-a-minute” vine are starting to take over. I attempted to capture the exercise with a Garmin VIRB-360 camera both on a fixed tripod, and a tripod I carried over my head. While mowing the sections I kept finding adult Praying Mantis which I tried to move away from the mower. The Praying Mantis are “good” bugs.

The fawns still have dots. While cooking dinner I saw these two in one of the wildflower meadow sections that I didn’t mow. You can see that the weeds have taken over. The deer seem to be immune to the electric fence.

Summertime Backyard Nature in New Jersey.

I received the newly released Sigma 100-400 mm telephoto zoom lens with a L-mount and spent the day testing it with a Leica SL2 camera. Leica, Panasonic, and Sigma formed an alliance to use the L-mount system. This lens provides a bit more reach than the Leica 90-280 mm lens. The alliance means that Sigma was able to make a lens that is fully compatible with the Leica TL2, CL, and SL2 cameras (autofocus and aperture control).

Something has been nibbling on the May Apple seeds, and wonder if a turtle found them. The wildflowers (Cosmos, Lance-leaf Coreopsis, Plains Coreopsis, Chicory, Marigold, Blanket Flower, Sunflower, Gloriosa Daisy, Shasta Daisy, Thistle, Lemon-mint, and Zinnia) are almost done for the season. I noticed an Eastern Chipmunk eating seeds under the birdfeeder. In 25+ years here, I’ve never seen a chipmunk in the yard before. I wonder if it will leave my Grow Towers alone. Kermit the bullfrog was out in the pond. Birds at the patio bird feeder today included Mourning Dove, Red-bellied Woodpecker, Blue Jay, House Finch, Chipping Sparrow, Song Sparrow, and Northern Cardinal. At one point a Blue Jay and Mourning Dove were feeding when an immature Red-bellied Woodpecker chased them away.
