King Rail populations have declined over the last ten years primarily due to habitat loss. King Rails are among northern Virginia birds that BirdLife International’s State of the Birds 2022 identified as at a tipping point for extinction, having lost half of their population in the last 50 years, and on a trajectory to lose another 50% in the next 50 years if nothing changes.
Wild bird populations in the continental US and Canada have declined by almost 30% since 1970, representing a loss of nearly 3 billion birds. This loss astounded Cornell Lab of Ornithology conservation scientist, Ken Rosenberg. Rosenberg led an international team of scientists from seven institutions in the analysis of population trends for 529 bird species. The journal Science published the study results in September.
The Spotted Owl just can’t get a break. Endemic to old-growth forests in the Pacific North west, the endangered owl’s population was already declining due to deforestation, but now they have been forced to accommodate an inconsiderate guest: Barred Owls. Native to the eastern half of North America, the Barred Owl’s territory has been expanding westward since the turn of the last century.
