One or two humming birds re-appear

For several weeks now there seem to be few if any humming birds at the feeder but the last two days I have seen one male in the morning feeding. They often seem to disappear during much of the summer and reappear in larger numbers in the fall. Perhaps it is because there are lots of flowers available but few around our place.

There are more house sparrows about than I have seen in some time with several youngsters clamouring to be fed among them. The house sparrow young remind me of some humans even though the young are able to peck and get the sunflower seeds themselves they would rather be fed by their elders! At least they have left the nest!
