The fungus called scarlet cup is a sign that spring is on the way. Only an inch or two across, its little cups are lined with bright red, spore-bearing sacs / Male northern harriers arrive from the southern U.S. Females will return about 10 days later. Look for them hunting over open wet areas / When the snow melts, don’t blame shrews for those tunnels you see in the lawn. They do live there, but the tunnels were made by moles / Crows are building nests
The earliest migrants are water lovers: red-winged blackbirds, gulls, kingfishers, and ducks are pouring north / Ravens are early nesters and may be seen now carrying building materials to the construction site / Heavy snow will send robins to sumac berries / Killdeer will return to dry fields soon after the snow retreats / Ermines are beginning to turn from white to brown / Screech owl females are sitting on four or five round, white eggs. The males bring food.
Some apple trees are showing pink buds / Daddy longlegs begin hatching from eggs laid late last summer / Blooming: swamp saxifrage, Mayapple, Jack in the pulpit, pussytoes / The first of perhaps three litters of northern short-tailed shrews is being born. These tiny animals have a poisonous bite and prey on mice and voles / Spring azure butterflies, silvery violet blue above, flitting through the woods signal the return of warm weather / Bobolinks begin to sing
Snow fleas are out hopping on the snow / Buttonbush, a wetland shrub, often keeps its fruits until the many waterfowl species that eat them return in spring / Saw-whet owls may call: too, too, too, too – repeated endlessly. Their short, mechanical whistles are sometimes mistaken for an alarm signal / Pussy willows will soon begin to open. Bring some indoors for an early taste of spring / Black, withered stalks of last year’s Indian pipes may still be erect
