Swainson’s Thrushes, aka Olive-backed Thrushes, hopefully Olive-backed replaces Swainson’s in the coming removal of eponymous English names by the American Ornithological Society (AOS).
It is easy to miss Olive-backed Thrushes in their deep-forest, forest floor haunts until they sing. Like their forest thrush taxonomic cousins they have a flutelike upward-spiraling ethereal song.
But even then you might not find them because they are excellent ventriloquists. They use movement, reverberation off dense foliage, and changes in volume to give the illusion of being in a different location.
This ability to be inconspicuous & use a large variety of forest habitats has served then well. They have bucked the trend of falling population numbers.
