Its leaves had turned yellow and seeds had fallen down. It was a daytime in the month of September when the tree was standing still and death-like. The life-less tree becomes alive by the arrival of the Goldfinch bird. The tree is her shelter.

Answer:

In the month of September, the tree would most likely be standing still and death-like. Here's an explanation why:

1. Changing seasons:
- September marks the beginning of autumn in many regions. During this time, the weather starts to cool down, and the days become shorter.
- As a result, trees begin to prepare for the upcoming winter by entering a state of dormancy. This means that their growth slows down, and their metabolic activities decrease.

2. Leaf shedding:
- In preparation for winter, deciduous trees, such as oak, maple, or birch, start to shed their leaves.
- The process of leaf shedding, also known as abscission, is triggered by the change in daylight duration and temperature.
- As September progresses, these trees gradually lose their leaves, and their branches become bare.

3. Lack of greenery:
- Since the tree is preparing for winter and entering dormancy, it is unlikely to be green and happy in September.
- The tree's leaves may have already turned yellow or brown and started falling off, resulting in a barren appearance.

4. Stillness:
- As the tree enters dormancy, its growth and movements slow down significantly.
- In September, the tree would generally be still, with no signs of active growth or movement.

Therefore, based on the natural processes and changes that occur during September, the tree would most likely be standing still and death-like, rather than alive, green, or happy.
