This picture of a male Purple Finch can be found on the "front page", so to speak, of the Purple Finch's species account. If you scroll down to the section where it shows "Field Marks", you will see that there is a series of 10 different photos. My photo is the 7th one (you have to scroll sideways through the series to get to it).
Also, this picture of a female Purple Finch is found on the House Finch species account page, shown in the "Similar Species" category. The above photo of the male Purple Finch is also shown here.
I was very excited to learn that my photos had been selected, and I'm so appreciative to Cornell for using them!
To those of you who participate in Project Feederwatch or NestWatch, or any of the Lab's other Citizen Science programs, don't be shy to submit any photos that you take of your birds. And even if you don't participate in citizen science projects, you can still submit bird photos to Cornell via their Flickr group, called Birdshare.
