"All the world is fresh and sweet...flowers blossom at my feet..."
~ from a song about Robins in Springtime my mother taught me as a young child
Observed outside my window, just a few minutes ago....
While growing up in Colorado, the first Robin of the year was indicative of Spring, but here in the Pacific Northwest, it is never really winter. So perhaps the sign here for the New Year is to look for "Spring" each and every day! (And remember, other seasons are nice, too!)
P.S. Upon searching for the song I learned as a child, I was quite surprised I couldn't find it online! I only found inexact fragments from schoolbooks dating to 1907. This is my best recollection from the age of 3 or so, as my mother helped me to sing this song over and over and over again multiple years in a row (a few words highlighted with  may not be exact, but very close)...when I would forget the words from the previous year, she would remind me. I would like this to be preserved somewhere for history because it was a real song I learned around 1967, almost surely taught to my mother when she was a young child of immigrants in the New York City area (probably just across the border in New Jersey) around 1930-33.
Robin dear, I love you so
I really wonder if you know
Where the [little] flowers grow
Hidden deep beneath the snow
I've been waiting for your coming, Robin dear
And I know you're [singing,] singing Spring is near [?]
All the world is fresh and sweet
Flowers blossom at my feet
Life [in] Joy is so complete [?]
