Phenology Calendar Mid-March

Posted by Wayne G. Barber
Third Week of March
One sweet sound of spring, a very high-pitched song, may now be coming from the brown creeper, a tiny insect-eating bird that spirals upward on tree trunks in search of prey. It might pass a nuthatch on its typical downward spiral.

Painted turtles are basking if it's warm. After they heat up, they will search for food.

First of two litters of red squirrels is born. The little ones will be leaving the nest to look for trouble in about six weeks.

Fourth Week of March
Yellow-bellied sapsuckers are beginning to return from points south. They lap up sap from holes in trees that they have drilled days earlier and will eat any insects the sap has attracted.

Some gray birch cones, each holding about 350 seeds, are still intact. Soon, spring winds will break the cones apart and disperse the seeds.

Woodchucks hibernate in upland burrows to avoid drowning in spring floods. They are out and about now, feeding on green grass. Source: Virginia Barlow
