Rusty Blackbird - Population

Population

Rusty Blackbirds have declined significantly in recent decades. The reasons are unclear, but habitat loss is likely a major contributor to the decline. Mercury contamination may be a problem for populations in northeastern North America. Rarer than previously believed, it is uplisted from a species of Least Concern to Vulnerable status in the 2007 IUCN Red List.

Additionally, citizen science projects such as the North American Breeding Bird Survey and Christmas Bird Count have determined that Rusty Blackbirds have dropped 85%–98% in the past 40 years. This is very worrisome for many people, as scientists are desperately trying to figure out what exactly went wrong. Sighting submission services such as eBird are encouraging birders to keep track of Rusty Blackbirds. The Rusty Blackbird Technical Working group has been actively coordinating and conducting research on this species since 2005

Famous quotes containing the word population:

    A multitude of little superfluous precautions engender here a population of deputies and sub-officials, each of whom acquits himself with an air of importance and a rigorous precision, which seemed to say, though everything is done with much silence, “Make way, I am one of the members of the grand machine of state.”
    Marquis De Custine (1790–1857)

    In our large cities, the population is godless, materialized,—no bond, no fellow-feeling, no enthusiasm. These are not men, but hungers, thirsts, fevers, and appetites walking. How is it people manage to live on,—so aimless as they are? After their peppercorn aims are gained, it seems as if the lime in their bones alone held them together, and not any worthy purpose.
    Ralph Waldo Emerson (1803–1882)
