What term is sometimes used to describe the Mourning Warbler due to its habit of relocating when thickets mature?

Answer

Fugitive

Because the species must relocate when its favored dense shrubbery matures past a certain point, roughly 7 to 10 years post-disturbance, the Mourning Warbler is sometimes referred to as 'fugitive.'
