Warm and sunny today. Bees are bring in pale yellow pollen. What could be blooming in January?
And now for something entirely different.
I have seen my bees bringing in pollen on a winter day. What I have seen is a dark orange colored pollen. Nothing in bloom, but they find faded blooms that are still standing. I don't know if it's nutritious. I have read that they prefer bringing in pollen over utilizing stored pollen.
Anyway Neil, I would say that was a good sign that all is right in the colony. It's also a good reason for not cutting down faded perennials in the fall. Native bees use the stems of some perennials and natives to nest in during the winter months too.
Could something be in bloom that offers yellow pollen? Witch Hazel, Hellebore, crocus, and willow are possibilities in your area. We usually don't see anything now but Hellebores. ( Writers note: The website censored the name of the willow variety. I will say it is the bush type with catkins.)
