Snow buntings are extremely confiding often settling within feet but never seem to stay put for long periodically flying off further up the slopes, probably to see what's on offer at the Ptarmigan restaurant higher up the mountain. They always return though usually every 20 minutes or so. The maximum we saw was about 40 birds in flight but only a high count 11 settled down at any one time. When the whole flock is in the air they resemble jewels as they twist and turn.
With the full sun it was enjoyable to sit and wait and then take a volley of shots as the birds fed. The flock had a habit of settling on the benches and tables and appeared to wait for a dominant male bird to fly down to the food before all joined in the bounty. Each feeding bout would last around a couple of minutes before they were off again.
I could have stayed a lot longer and didn't manage any decent flight shots but we were both done in after the mountain walk. May try to return later in the week but the weather forecast is poor so may not be possible.
