Seasonal Clues

Winter
Trees: Deciduous trees are bare while conifers remain green. Larch stands out among the evergreens. Bark textures become easier to notice: white birch glows against snow, and ash shows diamond patterns. Twigs and buds may be swollen before spring. Silver maple buds are large and fuzzy, while elm buds are pointed.
Animals: Migratory birds like robins, warblers, and swallows are absent, but resident birds such as chickadees, cardinals, and woodpeckers remain active. Mammal tracks in snow reveal deer, rabbit, fox, and squirrel activity. Signs like gnawed bark or burrow entrances indicate animal presence.

Spring
Trees: Bud break signals species-specific timing: maples leaf out early while oaks are slower. Flowers often appear before leaves on cherry, apple, and hawthorn. Sap flows peak in sugar maples during freeze-thaw cycles, while birch sap can also run. Emerging leaves include reddish new leaves on red maples and bright green leaves on poplar and willow.
Animals: Migratory birds return, including robins, warblers, and orioles. Frogs and salamanders begin calling near ponds. Early bees, butterflies, and dragonflies emerge. Mammals such as squirrels and chipmunks become active again after winter dormancy.

Summer
Trees: Leaves are fully developed, making species easier to identify. Dense canopies, such as beech and oak, provide deep shade, while sparse canopies of maples and birches allow more light through. Resin may appear on pine and spruce trunks or branches. Leaves may curl or droop under drought or heat stress.
Animals: Birds are nesting and fledglings can be observed. Insects peak in activity, including mosquitoes, butterflies, beetles, and dragonflies. Mammals such as raccoons, deer, and bears are active, often near water. Tracks may be harder to see in dense summer vegetation.

Fall
Trees: Leaves change color: sugar maple turns bright orange or red, red maple becomes vibrant crimson, silver maple pale yellow, and oaks brown or reddish-brown. Larch needles turn yellow and fall, while some oaks and maples may hold leaves longer. Seeds and fruits are visible, including samaras from maples, acorns from oaks, and persistent fruit on hawthorn and crabapple.
Animals: Migratory flocks of geese and swans pass overhead. Mammals prepare for winter: squirrels store acorns and deer bulk up. Insects decline as temperatures cool. Animal behaviors signal fall, such as chipmunks storing food and raccoons raiding fruit trees.

Cross-Seasonal Clues: Frogs and toads croak in spring and early summer but are silent afterward. Bees and butterflies are active in spring and summer but absent in fall and winter. Tracks and scat are reliable seasonal indicators, especially in winter snow. Leaves may react to weather: maples curl or darken before rain, and poplar or willow tremble in the wind. Twigs and stems shift color from green to reddish or brown as seasons change. Some maples and ash show bark exfoliation or darkening in winter. Hawthorn, crabapple, and black cherry may flower or fruit later than maples.
