Backyard Springtime Nature in New Jersey.

The deer are getting gutsy, moving in closer to my wildflower meadows, and nibbling on the recently planted forsythia and lilac shrubs. This one was making a salad out of some recently planted wildflowers under the weather station.

Backyard Autumn Nature in New Jersey.

I noticed a black squirrel eyeing the bird feeder on my patio today. For the past 25 years, the squirrels in my backyard have all been the grey variety. I do remember seeing a black squirrel in Princeton several years ago. So maybe the black ones are expanding their range.

Backyard Day and Nighttime Nature in New Jersey.

While moving some of the wood being used build the stairway to my patio, I noticed some holes in the ground with a relatively large cicada larva. It had spent the last 13 or 17 years in the ground, and is waiting for a rain storm before crawling to the nearest tree. There it will crawl up and got through the final metamorphosis to the insect phase. We can expect the loud noise of the cicada in the near future as they look for a mate.

Later in the afternoon, I saw a scruffy Cardinal at the bird feeder. Probably an immature bird just getting its adult red colored feathers. There were a large number of deer in the backyard. At least four fawns with spots,  four or more doe’s, and one buck with its new antlers.


After dark, I could see both the waxing gibbous moon and mars peaking in and out of the clouds. I couldn’t get both in the field of view with a Nikon D4 camera and 600 mm lens. Switching to a Nikon D850 camera and 500 mm lens I was just barely able to get both in the same image. The image of the moon was sharper with the Nikon D850 camera since it was shot with the mirror up, silent mode. With the exposure being used, Mars was just barely visible as a disk.

Late-Winter Backyard Nature in New Jersey.

The deer keep getting closer to the house looking for food as winter winds down. They have already clipped the yucca plants. Now all that is left is the grass.

Backyard Autumn Nature in New Jersey: Talking Doe.

I was testing the sharpness of the Nikon 600 mm f/4 lens coupled with a TC-E III 20 teleconverter (effective 1200 mm, f/8 aperture).
