I hope you can find peace with the sounds of nature. April is the best time of the year hear singing birds. I have chickadees and cardinals singing outside my window. Ducks are flying overhead, frogs and crickets are singing. Maybe the wind or the sound of waves or running water gives you peace. Listen for an enjoyable sound, or maybe search for complete quiet. What sounds of nature give you peace?
From 2 writers in the Star Tribune see below:
“Whatever it is that gets us thinking “spring” should lift our spirits and nudge us forward in this period of newness. The despair surrounding COVID-19 leaves us numb and sad, but events in nature’s spring tell us of better things to come.
These spring mornings are the best time of year to hear the symphony of bird music. Listen as tree swallows chatter; mourning doves coo; ring-necked pheasants crow; both northern cardinals and black-capped chickadees whistle; common grackles squawk; red-winged blackbirds trill; Canada geese honk; American robins sing “cheer-up, cheer-up;” and woodpeckers drum.” Jim Gilbert
“It’s the start of spring in the north. The birds are returning and in contrast to other years when I step outside, I listen for and enjoy the singing. It’s everywhere I stop. I try to listen to what they say — I could be imagining it, but they are saying it all goes on. We’re here. Nature is here. Despite your stress, relax. There’s nothing you can do about the pandemic other than listen to nature and seek refuge in compassion and the truth.” Bryan Hansel

Happy thoughts from the Huffington Post:
Spring is an opportunity to shed our bitter-weather blahs and adopt a happier, more mindful attitude. And what better way to do that than reconnecting with nature? There are some serious health perks to getting outdoors, from relieving stress to boosting brain function. If that doesn’t convince you, take a look at the inspirational illustrations below, which remind us not only to appreciate our lush surroundings, but know there’s always room for growth. So long, winter blues!

Spring in Minnesota is glorious! The snow piles have melted and icy snowy sidewalks are only a tiny bleep in memory. We have a yard with no turf grass and mostly native plants and grasses. The birds love to stop for plant seeds on their migration. I garden for the birds, bees, and butterflies. So far harbingers of spring have been juncos, robins, and the cardinals singing their morning spring song. The chickadees and the downy woodpecker sit in the lilac bush inches from my window. As you can see, it is time to cut off last year’s plants and grasses.
