Celebrating Northern Hemisphere Autumn

One of the features of the North Temperate Zone is that this time of the year, deciduous trees turn from green to bright colors. (Does the same thing happen in the South Temperate Zone in their autumn?)

Last week I visited North Carolina. North Carolina, from the coastal plain up to the fall line, may not be a fall-color destination like New England, but you can still see brightly colored trees there, such as
Tulip Tree
River Birch
American Hornbeam
All these turn to yellow. There are few that turn to red, but one that does is the Red Maple, which definitely lives up to its name this time of year. I didn’t get any pictures of that one.

So here is a thread for posting about the bright and beautiful colors of fall.


Utah Serviceberry
Chamisa and one of my favorite moths that visits them
Prickly Pear


remember there is winter in north india,(India) a bit chilling here, sad for me all the biodiversity is disappeared from here. My feets are very cold , My head is aching, but still I love winter here


Our colours all peaked after first Decade of October, now it’s snow-raining-snow period.)
Shiny Cotoneaster, European Spindle-Tree, Northern Red Oak turn to red.
But most turn to yellow, though sadly with trees it’s much more visible on planted ones (as they’re not mixed with conifers) which are not on iNat.
So there’s European Oak.

Mostly white birches here (with norway maple)

And November looks like this at best.


I have an inherited exotic fiddlewood, which turns orange going into our summer - when it pushes out fresh green leaves.
Cape Fynbos does the vivid colour in new spring leaves.


Here in Vermont we are in the midst of Stick Season, the season that comes between Fall Foliage and Winter Snow. It’s a great time to appreciate the beauty of the forms of the trees without their leaves, and to practice identification from buds and bark:

paper birch: https://www.inaturalist.org/observations/101160365
striped maple: https://www.inaturalist.org/observations/101184148

It’s also a great time to search for galls, without all those leaves in the way:

The conifers lend a bit of color:

tamarack: https://www.inaturalist.org/observations/101157647

And so do the young red oaks:

Fall is my favorite season. It offers our best mosquito-free weather and migrating birds - like the big Harris’s Sparrow - we usually only get to see for a few days each year. Sharing some autumn color pix:


We don’t have the same mix of trees that @ursus_arctos does in spite of being an hour and a half away. Our fall is usually short and the dominant colour is yellow and brown. These two shots were taken in early October -
The leaves behind the woodpecker are largely gone, the sparrow is in underbrush that tends to be a bit more colourful and last a little longer. We got a big dump of snow in the middle of last week, and everything is grey and white. And that’s it until May! Oddly, I saw fewer migrating birds this fall than previously. Only the usual suspects seem to be left.

Mid September. The whitish things on the grass are Canada Geese.


I live in NYC. As well as trees, there are also some woody vines and bushes that change color in spectacular ways.

Poison Ivy (native):

Virginia Creeper (native):

Japanese Creeper (invasive):

Oriental Bittersweet (invasive):

Winged euonymus (invasive):


Here are a few from earlier in the fall. We’re now mostly into “stick season” as @erikamitchell so aptly called it.


aaaaaaah so beautiful
