I checked that too Lin on the computer about the Nightingale & found the same as you so I don't know what they did with a Nightingale.
But it absolutely said Nightingale & I was surprised b/c all my life living here & never heard of a Nightingale.
It was some history book on Florida; it wasn't just some old wives tales book.
I have found the same as you with regards to both Blue Jays & Mockingbirds. We've had both nests & fledglings in our yard before & no problems. Oh, if the dog would get too close to where a fledgling was hiding out then a parent would swoop down screeching like a banshee but upon observation it was all for show & no go.
The dog never bothered one of the fledglings so all was well.
