The young Hummingbirds of the year are starting to arrive in the yard with 2 males and a single female joining the 3 or 4 adult males and several adult females that are still visiting the flowers and feeders with great frequency.
This young male decided to try and take over the yard on the 3rd and succeeded for most of the day before being pushed off by the adult male that still claims it as his. Not the best of shots but you can see the 2 or 3 red gorget feathers that have come in along his lower throat.
The 7 minute video below shows this youngster sitting on the branch I added to the deck, preening, flying off to chase others from the yard and returning for a bit more feather maintenance. This was shot at 1000mm from inside the house through the kitchen window.
