Migration is now in full swing. Have you seen any new birds returning to your yard? Have flights of geese, ducks or Sandhill Cranes flown over your house? If not, just wait for it! More than 300 North America bird species are heading our way after spending the winter in Central or South America. Believe it or not…on many nights you can actually hear the flight calls of song birds as they fly overheard, or see them (with binoculars) as they fly across the face of a bright moon. Head outside to listen and look just after the sky has fully darkened.
