Description

We compared abundance of migrating Willow Flycatchers and Wilson's Warblers to the abundance of arthropods in exotic and native vegetation at Bosque del Apache National Wildlife Refuge. We trapped arthropods using glue-boards in 1996 and 1997 in the same cottonwood, saltcedar, and willow habitats where we mist-netted birds during spring and fall migration. There were fewer arthropods, particularly flies, in saltcedar. We have mixed evidence that Willow Flycatchers and Wilson's Warblers respond to variation in insect numbers. Wilson's Warblers appear to be more abundant in willow than in other vegetation types in response to the abundance of small flies.
