Bird populations across Europe have experienced sharp declines over the past 30 years, with the majority of losses from the most common species, say the University of Exeter, the RSPB and the Pan-European Common Bird Monitoring Scheme (PECBMS) in a new study. However numbers of some less common birds have risen.
The cactus wren is the largest wren in the United States, at 8 1/2 inches. The brown-backed bird has a conspicuous long, white eye stripe and a heavily spotted breast. It is a common bird among thorny shrubs and cholla cactus in deserts and arid hillsides in the Southwest. This bird is also found in shade trees and open mesquite close to human habitation.
