I think my favorite coloration is the top one. The vibrant green eyes against the black feathers is quite striking, and almost evokes something with night vision goggles. I'm guessing the loss of echolocation, while partly fueled by the presence of eyes, was also in part due to many of the regions these inhabit are no doubt very noisy places to live, what with all the Cleaner Ukneuks tapping their trees, Umbral Sphinxs squeaking their choruses in the early morning and late evening, and such.
