seasons of the year (Fig. 3). There were no 
significant differences in capture rate of adults 
between dry and rainy seasons (P = 0.392, / = 
~0.8, n = 23). while most juveniles (70.5%) were 
captured in the dry season ( P = 0.001. t = —3.9. 
n = 23). 
Three nests of the Hyacinth Visorbearer were 
recorded in the area of typical compos rupestres 
within AP. One nest was active between 22 June 
and 22 July 2007. one nest was not active on 24
