Leadership of Winter Mixed-Species Flocks by Tufted Titmice (Baeolophus bicolor): Are Titmice Passive Nuclear Species?
Figure 3
Angular-angular correlation coefficients () for correlations between the movement direction of nuclear (TUTI; gray bars) or satellite (white) flock participants and flock movement direction in all cover types combined (All Cover), boundary (boundary between hardwood and open cover), hardwood, and open cover types. The sample size for each coefficient is above each bar. (a) Correlation coefficients in different cover types for all flock movement rates; (b) Correlation coefficients in different cover types for slow flock movement rates (<30 m/5 minutes); (c) Correlation coefficients in different cover types for fast flock movement rates (>30 m/5 minutes). Error bars represent 95% confidence intervals for each . Missing error bars represent 95% confidence intervals that were too small to be visible (CI < 0.001).
