Re: Where are the hummers?

As beekeepers, we notice that the Blue Gum Eucalyptus has started to bloom in profusion - much better than the last 3-4 years. When there is adequate bloom, the trees will pump out nectar by the gallon every day. There is so much nectar in a single blossom, that you can tip a flower and have a measurable amount of nectar flow into your mouth! Is it possible that the Hummers are using a tree-based source of nectar when it is available?

For the last few years, even when the rains have been adequate, the Blue Gum Eucalyptus appear to have had such a severe infestation of Eucalyptus Beetle that the flower bud set was minimal. Hence few flowers. For some reason, this year has been different and those trees that are flowering are booming.

The native pollinator of Blue Gum Eucalyptus in Australia is a native parrot, not an insect. You might try looking at flowering Blue Gum Eucalyptus in your area and see if the hummers have moved "up” in the world, so to speak.
