I am a writer/editor by profession and really don't like articles in which the authors say the same thing repeatedly -- like this article

So I skimmed it quickly. BTW, I typically see articles written in this manner on sites where the "author" is rewriting someone else's work or restating info from a fact sheet or other publication, to sell as some type of content for paying sites.
But I digress.
Yes, most of the summer I watched hummingbirds leave quickly when a bee or yellow jacket approached. I also saw more honeybees at our birdbath this summer than I've ever seen. These past few weeks are different -- I've seen two hummingbirds on the same feeder (a third one approaching means they all leave) and way more bees, yellow jackets, etc. just in the past couple of days. I'm thinking the birds decide they'll take the chance now as they build up energy for the long migration just ahead.
