I was on travel for work this week which mean any blogging or work on my website was delayed. When I returned, I had an email that was thanking me for my “Difficult Bird ID” page, where you can find information on differentiating between commonly confused species. There was also a request to add another page, discussing how to tell apart the three North American goldfinch species. I don’t normally think of goldfinches as a particularly difficult group to identify, but then again, here in eastern South Dakota, we only have the one species. Overall, geography is obviously a huge part of identifying goldfinches, as in the eastern half of the country, the only species of goldfinch you’ll find are American Goldfinch. However, if you happen to find yourself in parts of the southwestern US, you have three goldfinch species you may potentially encounter, with Lesser Goldfinch and Lawrence’s Goldfinch join the party.
The woman who sent the email lived in California and specifically was trying to figure out how to easily identify female goldfinches. That does represent more of a challenge than differentiating male goldfinches, and given that my Difficult Bird ID pages are some of the most visited pages on my entire website, I thought tonight I would go ahead and create another page that talks about ID keys for the three species.
As with many “difficult” IDs, for birders I think that difficulty melts away with experience, particularly when given keys to look for. Creating a page such as this helps me as well! I don’t run into Lesser Goldfinch, for example, unless I travel, but I don’t know if I could have identified a female goldfinch as either Lesser or American in the areas they overlap in range, until creating this page. Now I’ll know what to look for (bill color, and undertail covert color are giveaways).
A bit of a pain to create these pages, but as I said, they are frequently visited. Click below for the new Goldfinch ID page.
