It begins with a pair of binoculars; and a balcony, if you have one. If there is some greenery visible from your balcony, even better. But you need binoculars to begin this voyage. Mine are Bushnell binoculars from Amazon for about $35. They have a magnification of 10X50, which didn’t mean anything to me except that it seemed better than the 8X40 advertised by other brands. I use them every day, except during travel, and even that, I want to change.
