In late summer in eastern North America a different looking ruby-throated hummingbird (Archilochus colubris) shows up. If you don’t look closely you may misidentify it.
It doesn’t look exactly like an adult, pictured below, but it resembles the female.
So is it female? No!
See the red dots on the throat? It’s a young male, born this spring, who is already developing his red gorget.
Before he has red dots you can still identify him by the stippling (dotted lines) on his throat. This young male, below, has stippling without red dots.
Unfortunately the bird pictured at top was misidentified as female on Wikimedia Commons. I corrected the description but cannot change the filename that contains the word “female” so he will still confuse people.
Proving that you should not believe everything you see on the Internet.
