Spring pollen

Had a very beautiful day today. Got a lot of yard work done. Attempted my first apple tree grafts. Spent some time with the bees. All three of my colonies had girls out today. They are bringing in some light yellow pollen. Lots of light yellow pollen (see pics). I'm not sure what it is. The willows are barely beginning to bud. I've seen a crocus here and there but the dandelions aren't even up. Whatever it is, I'm glad they have it.

The TBH at Rosier's was especially busy (and quite friendly).
