Sounds just like a normal molt, they can vary in their times of dropping feathers. I see no reason for alarm.

Standard - I have not seen a hummingbird molting ever before. Thanks for posting the picture and the link to the article. Sarah - That is neat that you have captured a picture of one molting. It is so fun to watch them preen. Ruth

Perching on leaves = looking for prey or staking out territory. The lay their eggs on leaves or stems of aquatic plants.

You can save the seeds by drying them out even if they did freeze. Last year one of my nicest pumpkin plants grew all by itself, in the spot in the garden where I had chucked some pumpkin scraps. It got as cold as -20 last winter so those seeds were about as frozen as they come. Yet in the spring they sprouted right up. The only thing is that unless your pumpkin was carefully pollinated, your seeds may not be pure, and the pumpkins that grow may look nothing like you expect.
