Abstract
The age of savannah sparrow parents had no clear influence on nesting phenology, clutch size, or net reproductive output (number of young fledged) at the Isle Verte, Quebec, Canada. Older females started nesting earlier in 1 of 2 study years which had complete data. Nestlings reared in the second half of the season spent .apprx. 1 day less in the nest and gained weight sigificantly faster than those reared during the first half.
