Rather than posting those annoying flickr links that pop up (which I do try to delete) I thought I would send the youtube link to a 2 1/2 minute video of the bees. They are MUCH more active today, than yesterday. I would love to know if anyone has the exact name of this particular bee.. I was trying to figure it out when some were feeding, and gave up, since there were several species of bees present.

hope this works. If not it is listed under Bumblebee nest in Birdhouse Bonney Lake, something like that anyway
