BioOne Online Journals - Effects of Recreational Trails on Northern Cardinals (Cardinalis cardinalis) in Forested Urban Parks

"Trail use was estimated using cameras at seven of 14 sites. Nest attendance was not related to distance to trail, nest height, or trail use. We found little evidence that daily nest survival rates were related to distance to trail, nest attendance, trail use, or site. Rather, daily nest survival was best explained by and positively related to nest height. Though vegetation characteristics in randomly-located plots were unrelated to distance from trail, nests closer to trails were surrounded by more small stems (8 cm), less native vegetation, and were placed at greater heights and farther from the foliage edge. Thus, birds may modify nest-site selection in relation to recreational trails."

Not motorized recreational trails.
