Orientation Flights

I didn't do any inspections last week because we were away. We went to the Canadian Rockies for a few days. We stayed at Cathedral Mountain Lodge. The country is strikingly beautiful. We did see one young grizzly bear. I got some fishing in and actually caught some fish, but no hogs.
Above are two videos, taken one hour apart; they show the activity when bees are doing their orientation flights and the normal activity.
Bees that are between 7 and 20 days old make daily orientation flights. They do this to defecate (which healthy bees only do while flying), to get flying practice and to learn where their hive is and what it and its landmarks look like. This has to be done before they start foraging at 21 days of age. The flights occur in the warm afternoon, usually between 2 and 5 and last for 30-45 minutes. They fly only a few feet from the hive and then hover in front of the hive. They will flit to the side and back of the hive and will even rest on nearby plants. They fly in and out of the hive and when time's up, they all go back in.
I'll be going into the hive this weekend. I plan on putting in the queen excluder and doing some frame manipulation.
