My brother and I were on our favorite birding trail in my old hometown of Erie, Pennsylvania, when one of those fantastic bird flurries happened.

It was mid-May and the flurry consisted of four or five types of warblers, two brown thrashers, a blue-gray gnatcatcher, Baltimore orioles, a house wren and a few other species. When the flurry died down and I entered the species into my eBird report, I noticed something that struck me as odd.

When I entered house wren, the only option that came up was northern house wren. What the heck is that? I thought. I assumed that was the species I’ve always known as house wren, but I still wondered where the “northern” came from.

A quick internet search confirmed that the new official name for the house wren species that occurs in the U.S. is northern house wren. The southern house wren, formerly considered the same species as the northern, lives south of the U.S. and there are also five separate Caribbean endemic species. The split and name changes happened in 2024. Somehow, I missed the memo until now.
