Hi Baker, you gave me food for thought, or pollen for thought
I was under the impression that the bees store the pollen and when it becomes bee bread, that that is what they feed the baby bees. Like the pollen is softened, cured maybe, and the babies can consume it better.
On our warmer days my bees are out and about, not zooming like a flow is on, but definitely bringing in tan colored pollen. That would be from our evergreens. Cedars are especially full of pollen, we can bang a branch and pollen clouds up the air pretty good, enough to send our brother in law back home, and hour away, with an awful allergy attack.
