Migration and change in late August at western Montana's Spokane Bay

At Spokane Bay, near Helena, Montana, fall songbird migration is beginning. Yellow-rumped warblers and Wilson's warblers are passing through, stocking up on insects. Many summer birds are still here: the last yellow warblers still sing occasionally, and the sandhill cranes are foraging in the marsh. Meanwhile, I spotted a small flock of pinyon jays on the hillside - the first sighting of these interesting birds at this spot in the last 22 years!
