Wintertime Backyard Nature in New Jersey.

Heavy snow most of the day. The highlight was a Red-shouldered Hawk in a tree overlooking the birdfeeder. Later in the afternoon several Turkey Vultures soared by looking for a place to roost overnight.

Summertime Backyard Nature in New Jersey.

The new bird at the birdfeeder today was a male Rose-breasted Grosbeak. I’ve observed female and younger Rose-breasted Grosbeak before, but not the male with the distinctive rose colored breast shield.

Contact me if you are interested in a Time-lapse Video of the Morning 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.

Daily Electric Energy Used (48.0 kWh) from Sense. Daily Solar Electric Energy Produced (32.6 kWh) from Sense and SolSystems. Lots of clouds. A deficit of 15.4 kWh.
