Table 1.

Average distances from the nearest treeshrew to the sparrowhawk; distances were significantly greater for groups where drongos were absent (Wilcoxon Z = −2.0411, p = 0.041, n = 144). (ts, treeshrew; dr, drongo; sh, sparrowhawk.)

drongo	mean distance of nearest treeshrew from the sparrowhawk (m)	group composition	mean distance of the nearest treeshrew from the sparrowhawk for individual groups (m)
absent	7.35	1ts, 1sh	6.8
		2ts, 1sh	7.45
present	5.44	1ts, 1dr, 1sh	5.62
		1ts, 2dr, 1sh	4.66
