Early bird special: Spring pops up super early in much of US

Spring has sprung early — potentially record early — in much of the United States, bringing celebrations of shorts weather mixed with unease about a climate gone askew.

Crocuses, tulips and other plants are popping up earlier than usual from Arizona to New Jersey and down to Florida. Washington is dotted with premature pink blossoming trees. Grackles, red-winged blackbirds and woodpeckers are just plain early birds this year.

The unseasonably warm weather has the natural world getting ahead of — even defying — the calendar, scientists said Tuesday.
