As promised from last week, here is a review of Brown Thrush ID for those species at their peak now. Veery (VEER), Swainson's (SWTH) and Gray-cheeked Thrushes (GCTH).
A few key field marks for identifying the brown thrushes are the appearance of eye ring, the spotting on the chest, and the color of the back.
|Left bird has a visible eye ring. The right bird does not.|
|Bird on left is the only bird with an eye ring in this photo. |
Note the differences in overall color as well.
|Back coloration of these birds are both olive brown|
|Back coloration on these birds are left olive brown and right reddish brown. Notice the markings of the secondary coverts on the bird on the right, this indicates a hatching-year bird and can give the appearance of a wing bar on some individuals.|
|Compare spotting on these and look for eye rings. Bird in center has blurry spots. Also appears more reddish brown than the other two. |
Left to Right: Swainson's Thrush, Veery, and Gray-cheeked Thrush.
Guess which ones are here:
|Birds from left to right: SWTH VEER GCTH|
