which was appropriate to avoid double
counting birds between two points (Buckland, 1993; Sutherland, 1996; Gregory et al.,
2004).Thus, there were 45 points for each trail
The point distance sampling was conducted from January 2007 until December 2008
covering both the breeding (January to May) and non-breeding (June to December) season
and visits took place in the
breeding season (once; from April to May 2008) and non-breeding season (twice from
September to December 2007).
