We’ve just completed a new plate that details harlani identification. This is the first plate of many that we hope to make available for how to distinguish between all subspecies. You can download a high resolution version of this plate by clicking on the image below. Stay tuned for more!

Appreciate the work into aides like this. Helps in the ID process and helps you be a better birder. Will add to my resources. 😉
