This morning while conducting a survey for RMBO I found two Indigo Buntings along the Colorado River (one in Colorado and one in Utah). Both were singing in riparian habitat along the river. It was very easy to document breeding by several species - Western Kingbird, Northern Mockingbird, Common Raven, Black-throated Sparrow, and Lark Sparrow just to name a few.
This spring and summer RMBO is conducting a study to determine if the tamarisk leaf beetle could be impacting riparian birds in western Colorado and eastern Utah. In the area that I surveyed this morning the tamarisk is nearly completely defoliated (by the introduced beetle) and the beetles and their larvae were easy to find. It will be interesting to see the long term effects this beetle has on riparian areas in Colorado. We are hoping that this project will be long term too in order to determine if the beetle does make a difference.
