This morning I wanted to share three male Yellow Warbler photos that I took yesterday morning in a Morgan County canyon. I barely had time to stop my Jeep at this location when I noticed the warbler moving around in the willows. Even though the warbler wasn’t out in the open in this image I liked it because this is how I find these warblers most often. By that I mean partially hidden.

As I photographed the bright male Yellow Warbler I paid attention to the willow leaves. Typically at this time of the year the leaves are covered with aphids. I noticed yesterday that there weren’t any visible aphids on the leaves.

The Yellow Warblers and other warblers that visit these willows eat aphids so it appears that this year they will need to find alternate food sources. Usually there are aphids on the nonnative Musk Thistles in the mountains and so far this year I haven’t seen any on those plants either.

There are plenty of other insects in the area but I do wonder what happened to the aphids.

This male Yellow Warbler has been going through a molt which means he is getting ready for fall migration which is now only a few weeks away. He is replacing his tail feathers and currently his tail looks rather stubby. Very soon those tail feathers will be their normal length.

I enjoyed having this male Yellow Warbler in my viewfinder yesterday morning.

Life is good.
