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.
