We examined the effects of presettlement forest restoration treatments on the nesting success of Western Bluebirds in ponderosa pine forests of Northwestern Arizona, USA. From 1998 to 2001 we monitored 97 active nests, 41 in current-condition untreated forest and 56 in restoration treated forest. We found no effect of restoration treatments on clutch size and little effect on the number of nestlings per nest. In treated forest, number of fledglings averaged 1.6 times greater and probability of a nest surviving to full fledge was 4.2 times greater.
