Although we were able to study only a few species in detail, we speculate that multiple
nesting and perhaps double-brooding is common given the long breeding season (often > 6 months)
and the low nesting success rates (< 30%). Abbott’s Babbler females made an average of 2.5 nesting
attempts in the 2003-2004 nesting season, with some making as many as four nesting attempts and at
least one pair successfully fledging two broods (Pobprasert, 2005).
