Paper birch
Betula papyrifera
Mature trunks typically have white bark peeling in papery sheets, with dark horizontal markings.

Paper Birch & Yellow Birch
Start with naturally exposed bark, then compare leaves and seed-bearing structures. A young birch may not yet show its familiar bark.
Observe from a permitted path. Use attached or naturally fallen material without picking or peeling. Photographs show individual examples, not every variation or a common scale.
Bark
Bark is the clearest starting clue in this pair, but age changes its appearance. Leave every layer attached.
Yellow birch
Betula alleghaniensis
Younger trunks often show shiny bronze or yellow-silver bark curling in thin strips; old bark becomes darker and scaly.
Leaves
Leaf shape overlaps. Compare several mature leaves, then return to bark and seed structures.
Paper birch
Betula papyrifera
Alternate, pointed leaves have toothed edges and are often broadly ovate.
Yellow birch
Betula alleghaniensis
Alternate leaves also have pointed tips and doubly toothed edges, often with a more elongated outline.
Seed-bearing structures
These are seed-bearing structures, not the slender male flower catkins. Their seasonal stage matters; combine them with bark.
Paper birch
Betula papyrifera
The cylindrical seed-bearing catkins commonly hang downward as they mature.
Yellow birch
Betula alleghaniensis
Compact seed-bearing catkins are upright on short shoots.
Look again before you decide.
These clues compare this pair; other species, hybrids, age, and growing conditions can complicate identification. If the features disagree, keep observing and consult a local field guide or knowledgeable person.
