Status summary

Coot territories recorded by WBS may be on linear waterways or on adjacent lakes, making WBS arguably more representative of Coot populations as a whole than CBC, which was less likely to record Coots in their main habitats. Both WBS and CBC/BBS trends for Coot indicate a shallow increase, although small CBC samples suggested a rapid rise in the late 1960s. Winter abundance on large still waters, as monitored by WeBS, has also shown consistent moderate increases since the early 1970s (Musgrove et al. 2001).
