Abstract: The migration phenology of many bird species has changed over the past few decades, but the extent to which such changes affect the nesting phenology remains little known. Studying avian reproduction in the boreal forest, often referred to as North America's bird nursery, is challenging because of the large size of this biome. I evaluated songbird nesting phenology during the past 26 years in a boreal forest in eastern Canada, Forêt Montmorency. I used the observation of food transport in adults as an indicator of parental status, considering the imperfect detection of this status through hierarchical models of site occupancy. Contrary to expectations related to the advance of spring migration in North America, models revealed a delay of two weeks in the nesting season for residents and short-distance migrants and of one month in long-distance migrants during the study period. These results remind us of the value of regional studies when we are interested in reproductive phenology.
