Chestnut-sided warbler and ruby-throated hummingbird

I know that Project Noah prefers one species per spotting but am hoping this exception will be acceptable. The chestnut-sided warbler in the upper left was obviously too close to the nest of the ruby-throated hummingbird (lower portion of the photos). The much smaller hummingbird flew furiously at the warbler to drive it away and kept it up for quite some time, finally achieving success as the warbler tired of the harassment and flew away.
