Bird behavior can be fascinating to observe. Yesterday I was allowed a peek into the leaf-bathing behavior of this MacGillivray’s Warbler I photographed high in the Wasatch Mountains.

I was sitting in a mobile blind hoping for birds to show up when I noticed a dew-covered snowberry bush below me quivering. The quivering would stop briefly and then start back up again. I couldn’t make out what was causing the low bush to move but I kept watching for a bird or animal to appear.

At one point I thought it might have been a chipmunk causing the movement because I have photographed them eating snowberry blossoms. I couldn’t see feathers or fur though. Basically I could see the snowberry bush trembling slightly while everything else around it was still and that piqued my curiosity.

It took about five minutes of observation before I could finally see what had been causing the snowberry bush to quiver. I saw some yellow feathers, a dark eye and a pointy little bill in between leaves. Then I saw the bird shake its feathers before it popped into my view. By then I knew it was a MacGillivray’s Warbler and that it was soaking wet.

Since I knew there weren’t any puddles under the snowberry bush I thought that the warbler may have gotten wet from the dew that I could see on the bush.

When I came home I did some research and found out that some smaller birds deliberately push and flutter against leaves or flowers of plants that contain dew or raindrops until their plumage becomes drenched and that this behavior is called leaf-bathing.

This MacGillivray’s Warbler flew from the snowberry bush to another spot where I could see it shaking the dew off of its feathers but I couldn’t get unobstructed views or photos of it.

I’m always learning more about the birds I am so passionate about.

Life is good. Stay safe.
