A lot has been written in blogs and elsewhere about Autumn ( Sept 1 - Nov.30). There's description of change in color, falling leaves, drop in temperature, animals preparing for winter hibernation, migration of birds in search of food, autumn holidays etc..
Autumn always reminds me of the famous song the 'Falling Leaves' (in french the 'Dead Leaves'), and of the famous singers performing it, among them: Ives Montagne (in french), Nat King Cole, Andy Williams, Frank Sinatra (in english).
The musical versions of this song on Youtube are not very good , I'm afraid. The lyrics are beautiful and even worth memorizing. It' s a romantic song mentioning color (red and gold), the departing summer, the approaching winter, the falling leaves that make the singer miss his darling.
Here are the lyrics:
The falling leaves, drift by the window /The autumn leaves of red and gold
I see your lips the summer kisses / The sunburnt hands I used to hold
Since you went away, the days grow long
And soon I'll hear old winter's song
But I miss you most of all, my darling
When autumn leaves start to fall.
