Four-Years Ago (28-March-2016) — Ghana

Gone to See the World. Semester at Sea Spring 2016 Voyage on the MV World Odyssey. Day 83: Takoradi, Ghana

While docked at the port in Takoradi, Ghana I saw this large crow like bird with a white chest and neck. Later identified as a Pied Crow.

Backyard Spring Nighttime Sky Over New Jersey.

Star Trails looking up and west. Only about an hour with limited clouds. Not many jet trails crossing the western sky as air travel has been significantly curtailed. One meteor trail in the second image.

Backyard Springtime Nature in New Jersey.

There were a number of birds out today. Several Juncos feeding on the ground, a House Finch, Marsh Wren, and several Northern Cardinal feeding at the bird feeder. A “murder” of Black Crows were working the lawn looking for earthworms. The earthworms were out because the ground is saturated. I haven’t seen any Robins yet this spring that would also be after the earthworms. The crows attracted the attention of a Turkey Vulture that landed looking for something to eat. The crows quickly joined together making a lot of noise and then chasing the turkey vulture away.
