I haven't seen any waxwings at the arboretum recently, but I live about 2 km south of the university and today we had a flock of 200 waxwings, mixed bohemian and cedar, in our backyard. So they are definitely still about.
Thanks Rob ... we were a bit worried about the Thrasher over this cold spell, but he seems to be doing quite well. He's also become fairly tame, and not at all bothered by the traffic in and out of the arboretum center, which is sometimes quite heavily used for conferences, luncheons, meetings, etc.
