The geese have been gathering this week and last for their trip southwards. They will be taking
all many of their little microbes with them. (Some are dropped behind in the— diminishing over time— tundra ponds and grasses.)
The alarm has gone up in the lower 48 with expanded bird sampling across the US. It is very unlikely there is any HPAI to accompany the birds, but it is easier to get a cloaca swab than to give tourists the bum’s rush.
The geese, swans, and cranes are among the last to leave. The little birds left about 3-4 weeks ago. The only thing left for combating the flying biting insects is a good swat. And a hard freeze.
