Almost one in five landbirds needs conservation action

Golden-winged Warbler is one of 19 land birds on the Red Watch List.

A new analysis of all landbirds in the continental U.S. and Canada documents widespread declines — a troubling indicator of the health of the birds and their ecosystems.

According to the new Partners in Flight Landbird Conservation Plan, 86 of 448 landbirds, nearly 20 percent, are on a path toward endangerment and extinction in the absence of conservation action.

Of highest concern are 19 species on the plan‘s Red Watch List (see below): Gunnison Sage-Grouse, Lesser Prairie-Chicken, Golden-winged and Golden-cheeked Warblers, Black-capped Vireo, Bicknell’s Thrush, Tricolored Blackbird, and a dozen other much-threatened species with restricted distributions and small, declining populations. For them, the goal of conservation action is recovery.

Sixty-seven more landbirds — including 11 warblers, nine sparrows, five game birds, and five owls (Flammulated, Whiskered Screech, Snowy, Spotted, and Long-eared) — were placed on the Yellow Watch List, indicating that work is needed to prevent or reverse their decline.

The plan also describes 24 “common birds in steep decline” — landbirds that are still too numerous or widely distributed to warrant Watch List status but are experiencing long-term declines. Almost one-third migrate to Central or South America. Each has lost 50-90 percent of its population since 1970, and most are projected to lose another 50 percent in the next 20-25 years. The goal of action is to stabilize populations.

Terrell D. Rich, author of the cover story of our August 2016 issue about the 100th anniversary of the Migratory Bird Treaty Act, was one of the plan’s 23 co-authors.
