Like several others with posts below, I started to concentrate on bird photography during Covid-19 and then found many previous bird photos in my collection from the before times. I first came across Melissa Groo in Ray Hennessy's podcast, Wildlife Photo Chat. It is a great episode. (http://rayhennessy.com/wildlife-photo-chat ).
I find it calming to head out to a park or preserve with my camera and see what birds I can find. I shoot with a Nikon D-750 and recently added a 300 mm and 1.7 teleconverter. I rented a number of lenses before settling on this combination for being lightweight with a great reach. I enjoyed the assignment to explore the Macaulay Library. It confirmed that I should be fine to shoot with my existing equipment for awhile.
