Autumn Backyard Nature in New Jersey.

The flock of feisty Pine Siskin descended on the birdfeeders in the morning. Then all of a sudden the birds disappeared. I noticed a Cooper’s Hawk perched on a tree in the backyard. After the hawk left, some of the local birds (Mourning Dove, Black-capped Chickadee, White-breasted Nuthatch, House Finch, and a few Pine Siskins) returned to the birdfeeders. Also in the afternoon a number of Turkey Vultures and Black Vultures found a dead critter.

Contact me if you are interested in a Time-lapse Video of the Morning or Afternoon session 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 wondered why there were periods of time when all of the birds at the feeder disappeared. Then I saw a Bald Eagle in a tree. First time I have seen a Bald Eagle in my backyard. Soon after a bunch of American Crows started harassing the Bald Eagle causing it to fly away. A bit later, I saw a Cooper’s Hawk in the same tree that the Bald Eagle had been perched. As before, a bunch of American Crows started harassing the Cooper’s Hawk causing it to fly away. Finally, some Turkey Vultures showed up.

I also noticed an Eastern Chipmunk under my birdfeeders. A new resident in the neighborhood. It appears to have a tick above its nose.

Summertime Backyard Nature in New Jersey.

I admit I am not spending as much time watching the birds or wildflowers while the butterflies and clearwing moths are present. The only bird for the day was a Turkey Vulture soaring while I was working in the yard. I also found a single Tiger Lily flower. Every year I think the deer ate them all, and then one out of the 250 bulbs planted three years ago will pop up. I also noticed some different Larkspur flowers in the wildflower meadow.

I didn’t see the Monarch or Eastern Swallowtail Butterfly today. The Clearwing moths were present in the Bee-Balm/Lemon-Mint wildflower meadow along with many Bumblebees. I think that there are two types of Clearwing Moths working the flowers. The Clearwing Hummingbird moth (Hemaris thysbe) which is the larger of the two, and has light-colored front legs; and The Clearwing Snowberry moth (Hemaris diffinis) which is smaller, and has dark/black colored front legs. I will be spending the next few days trying out different camera and lens combinations to figure out the best kit is to capture images of the Clearwing moths.
