ABSTRACT
Cooperatively breeding birds tend to exhibit high adult survival and relatively small clutch sizes.

a landscape with slow territory turnover. However, this hypothesis evokes a puzzle because high
fecundity should also lead to problems in territory acquisition because of the large number of
