Song & Call Comparison
Undulated Tinamou
A loud, repeated undulating whistle that rises and falls — matching its name 'undulated'. Carries well through várzea forest and wetland edges across its broad range.

Found in scrubby hillsides and forest edges from Mexico south through Central America to Honduras. Sedentary at low to mid elevations.
Solitary Tinamou
