March in Nature: What to Look For Across the U.S.
Happening nowMarch is when migration gets real: waterfowl peak across the middle of the country, the first songbirds push north, and ruby-throated hummingbirds reach the Gulf Coast states in mid-to-late March. Spring ephemerals open in southern and mid-latitude woodlands. No major meteor shower peaks this month; the equinox around the 20th marks the turn to longer days than nights.

March is the month the dam breaks. However winter went, the northbound push is now unmistakable: enormous flights of ducks, geese, and sandhill cranes move up the middle of the country — the crane gathering on Nebraska's Platte River is one of the continent's great wildlife spectacles and peaks this month — while the first insect-eating songbirds, phoebes and swallows and blackbirds, filter back behind the thaw. On the Gulf Coast, the first ruby-throated hummingbirds of the year arrive from the Yucatán in mid-to-late March, the leading edge of a wave that will take until May to reach the northern border. On the ground, the spring ephemerals begin — bloodroot, spring beauty, trout lily, hepatica — the brief woodland wildflowers that race to bloom before the trees leaf out and shade them over. The show starts in southern woodlands early in the month and walks north week by week. As always in early spring, latitude is everything: coastal Georgia and coastal Maine are living in different months that happen to share a name. The state pages are where the specifics live.
Bird migration
Waterfowl migration peaks across much of the interior — refuges and river valleys in the middle of the country host the year's biggest concentrations of ducks, geese, and sandhill cranes. The first songbird wave follows close behind: red-winged blackbirds, phoebes, tree swallows, and kinglets push north early, and ruby-throated hummingbirds make landfall along the Gulf in mid-to-late March. Feeders are worth keeping full through the transition — late snows concentrate hungry early migrants dramatically.
What's blooming
The spring ephemeral season opens: bloodroot, spring beauty, hepatica, and trout lily in southern and mid-latitude woodlands, moving north as the month runs. Red maple and willow flower widely; in the South, redbuds begin by late month and the Texas Hill Country's famous bluebonnet season gets underway. Desert Southwest wildflowers — in a good rain year — can be at their peak now.
In the night sky
No major meteor shower peaks in March. The month's real astronomical event is the spring equinox around the 20th, after which days outlast nights everywhere in the country for the next six months. Evening skies straddle the seasons: Orion and the winter stars sink west at dusk while the spring pattern — Leo high, the Big Dipper overhead — takes over the evening. A fine month for learning the transition, and dark hours are still reasonably early.
In the garden
March is the busiest transition in the garden calendar. The South is fully planting — warm-season crops go in along the Gulf by late month — while mid-latitude gardeners sow cool-season crops (peas, lettuce, brassicas) as soil dries, and northern gardeners start the main indoor seed wave. It's also the last comfortable window in most regions to finish dormant pruning and to resist cleaning up beds too early — overwintering insects are still asleep in the stems and leaf litter.
