Long term trend
UK: Rapid decline
 
Status Summary
The CBC shows severe declines in Turtle Dove abundance and the BBS confirms that these declines are continuing. Although not statistically significant, analysis of nest record cards and ringing data for farmland Turtle Doves suggests that productivity has increased while annual survival has fallen (Siriwardena et al. 2000, 2000b). Hunting during migration is a possible cause of the decline to add to those related to agricultural intensification that have been postulated for other farmland seed-eaters (O'Connor & Shrubb 1986, Krebs et al. 1999).
