Some days when photographing one bird at a time is not challenging enough, I like to photograph them in pairs. Like the Wood Ducks. When that’s no longer challenging, I like to photograph pairs of different bird species together. Or, maybe I didn’t even realize that Song Sparrow was in the shot when I was photographing the White-throated Sparrow on the side of that tree. What’s the most likely scenario for this world-class wilderness explorer?
