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.
