February is the time of year hazel alder blooms in our wetland. The plants are monoecious, having both male and female flowers on the same plant. The wine-red female flowers stand above the amber male catkins and are pollinated via the wind, or through the tap of a naturalist’s finger.


The shrub is also called smooth alder, common alder, tag alder, or Alnus serrulata in Latin terms. It’s most often encountered near water: streams, rivers, lakes, ponds.

The seeds produced by the plant are eaten by a variety of birds and small mammals. The leaves or twigs are browsed on by deer and the shrubs themselves provide shelter and nesting locations for many species of passerines. I often associate the shrub with Tyrannus tyrannus, eastern kingbird. It’s a classic image, a kingbird perched atop a pond-side alder in late April or early May.

Our alders grow on the north side of the wetlands in Explore the Wild. As mentioned, they’re in bloom now.
