This time of the year is fun and exciting, if you happen to live in a northern climate. After several months of winter, with very few birds to photograph, you get an explosion of life. Each morning you wake up to birds singing outside the window. Most of those birds are males. In most species it is the male that does the singing. However both the male and female northern cardinal sing. Even when on the nest the female will sing. Her song is often longer and more complex then her male counterpart.
