We went to Emma Long Metro State Park in order to see this endangered species, whose only breeding location in the U.S. is in Texas. Getting to the park, we were immediately greeted by the buzzing call of these beautiful warblers - but they were heard and not seen. The little warblers were tenants of the tree tops, and hard to see even when they came closer. We got a few good looks, but this was the best shot I could manage. Still, they were gorgeous birds that I was grateful to see.
