Clay-Colored Thrush

I just did a post on the black-billed thrush, a bird we saw a lot of at Tinamu Reserve in Colombia. There was another similar bird, the clay-colored thrush, I was looking for. The primary difference between the two, as far as I knew, was a black bill for the one and a clay or lighter colored bill for the other. I left Tinamu and Colombia pretty certain I'd gotten a number of photos of the clay-colored in addition to the black-billed. However, as I started looking at my photos I was dismayed to find that birds I'd thought were clay-colored were actually black-billed, with banana smeared on their bills from the feeding stations. I ultimately determined that I'd seen no clay coloreds. Then this evening as I was looking through the photos again, getting ready to delete them, I spied what I thought might be a clay-colored and got a positive result on iNaturalist. I'm thrilled!

The clay-colored thrush is the national bird of Costa Rica. It is found as far north as south Texas and northern Mexico down to northern Colombia.

It looks quite similar to the black-billed thrush except for the bill that is greenish-yellow with a darker base instead of black.
