Short day length trigger Fall events

Day length even more than temperature is the trigger for Fall migration of birds and leaf color changes.
As hours of daylight shorten I am seeing the first signs of Fall.
Tree leafs are beginning to change from dark greens to lighter yellowish colors with tinges of red.

Trees have slowed their growth and are getting ready to shed leafs and go dormant for winter hibernation.
Flowers are in full bloom in an attempt to produce viable seed for next years growing season.
Here that means it is sunflower season and everywhere you look sunflowers are in full bloom.

Birds that I haven’t seen in several months are returning to feed and build fat reserves to continue their long migration south. Some over winter as far south as southern Mexico and central America.

Several different types of hummingbirds can be seen in the early morning hours feeding. Getting ready to move south where they will over winter.
My tiny garden is on the edge of the fall migration flyways for Ruby throat, Black chin, Broad billed, Rufous and Broadtail hummingbirds.

  1. In England its been a difficult time in the garden, just because for so long it was so dry and we had to water twice a day. Then the weather and the temperature changed to wet and cool and before we knew it, it stopped raining and warmed up again. I haven’t lost many plants but i’m in need of a rest 😆

  2. Last week we had warm, humid days. Dozens of Monarch butterflies feasted on the last remains of garden blooms, especially the Mexican Sunflowers. Then Hurricane Michael passed East of us. We got the winds fromt he north. The next day all of the butterflies were gone… heading your way on those currents to the south. – Oscar

    Thank you for visiting my blog and liking my posts about planting garlic. I have browsed through your blog and found some interesting gardening information. It’s nice to read different perspectives on gardening from other people.

  4. Not a hard frost yet in my corner of Hardwick, Vermont, although freeze advisories again tonight. Gorgeous foliage, geese flying southwards to others, the definite end of the swimming season.

    • We seldom have a real fall season. Mostly we jump from cooler summer weather straight into winter weather starting sometime near thanksgiving holiday.
      Happy fun Vermont fall and winter season.

  5. I love brisk autumn weather. But this weather — soggy drizzle with temps barely above freezing — this I could do without. Alberta, Canada 🙂

    • In SW Oklahoma it is still a number of weeks before I will see a hard freezing night. That most often occurs about the second week of November.

  6. It’s nice to watch the leaf colours change, and sunflowers blooming is a real treat! In the Southern hemisphere it is spring, I am sowing seed. Happy autumn! 😁

  7. Hummingbirds! I’ve never seen those. I live in the UK. Autumn is just starting, some of the summer migrant birds have moved south and I’m waiting for the geese to come back from the far north.

  8. Ah, you are so lucky to see the birds you do, especially the hummingbirds! Although I love seeing the Irish birds, I miss seeing my East coast varieties…

  9. We are about to fill our feeders for seasonal visitors during autumn and winter. No great surges yet to note, although I have seen smaller birds, starting to gather in the mornings ready to fly together away to warmer climes, probably to Africa.
    Our garden is a constant runway to pigeons, doves, woodpeckers, robins, blue tits, coal tits, hedge sparrows, wrens and the odd bunting.
    The magpies and ravens never leave, sadly, but seeing birds in the garden is always a pleasure even though they may not be my favourites.

  10. Isn’t it great that they stop in on their way south? I miss the birds in the winter. We have a few toughies that hang in there through the long wet winter, but most of them (the smarter ones) go south. I hope they overwinter well and come back to us in the spring.

  11. Our ruby throated hummingbirds left here a couple of weeks ago. We miss them. It’s wonderful to think they are stopping and feeding t your feeder as they head south. Our trees are all gold now and we’ve had our first frost. This is my favourite month. It’s cool, no more mosquitos or ticks and at night I can snuggle up under a fluffy quilt. I love September.
