Interesting Facts

 The Crissal Thrasher is the only thrasher that lays unspotted eggs.

 Their nest is usually built close up under a large branch, making access rather difficult. The location seems to afford protection from both aerial predators and from the direct rays of the sun.

 It walks and runs around its territory more than it flies. Even when disturbed by a person or a predator it is most likely to run away to cover.
