Subject: [cayugabirds-l] A question on Eastern Bluebirds trails
In recent years it seems that Eastern Bluebird trails are raising more Tree
Swallows than bluebirds if they are anywhere near water. Has there been any
research on whether we are artificially raising the numbers of Tree Swallows
by placing bluebird nestboxes in proximity to water?
