Tricolored Blackbirds experience large annual breeding losses associated with crop-harvesting activities and insufficient prey abundance.

The Evening Grosbeak is featured on the cover of the 2016 PIF Landbird Conservation Plan, as it has the dubious honor of experiencing the steepest population decline (92% since 1970) of all landbirds in the continental U.S. and Canada.

Sprague’s Pipit populations have strongly declined due to the extensive conversion of native prairies to agriculture across much of their range.

While harvested landscapes have increased throughout its breeding range, the Olive-sided Flycatcher has continued to decline, suggesting that conditions on the wintering grounds may be driving its negative population trend.

As an extreme habitat specialist, the Bicknell’s Thrush has a very limited range, breeding primarily in high elevation stunted montane spruce-fir forests of the northeastern U.S. and southeastern Canada.

Le Conte’s Thrasher is an uncommon resident throughout the desert and scrub habitats of the American southwest and northwestern Mexico.
