4 July 2022
Some Rules of Thumb for Nature are timed “by the 4th of July.” Here are three. Can you think of more?
Corn is knee high by the 4th of July. Or at least it should be. This year in Minnesota there was worry that it might not come true. KARE 11 in Minneapolis reports:
Native rhododendrons bloom by 4th of July in the Laurel Highlands. Cultivated rhododendrons bloom in May because they’ve been bred to do so.
Most songbirds stop singing around the 4th of July. Others will follow this month.
Birds sing to attract mates and maintain their nesting territories. Those that migrate to Central and South America are on such a tight schedule that they finish nesting and stop singing by early to mid July. Song sparrows, robins, and cardinals are still singing because they have new nests this month.
When is the last time you heard a Baltimore oriole sing? For that matter, when did you last see one? He won’t leave until September but he is far more discreet than he was in May.
