Are you anxious to see the return of ruby-throated hummingbirds? If so, now might be a good time to start cleaning up the feeders and setting them out, because they usually start showing up around early May.
We seldom give plant sex much consideration, but some species of flowering plants produce flowers with both male and female reproductive structures in the same flower (perfect flowers). Most of the plants you are familiar with are in that category. Other species produce separate male and female flowers on the same plant.
Spring is often punctuated by a series of new sights and sounds as winter gives way to summer. It seems like each new sighting of a bird, for example, is duly noted and announced to others. Sighting the first robin of the season is probably the best example, but don’t forget to pay attention to the many other varied sounds of spring.
