2017 Middle Rio Grande Southwestern Willow Flycatcher Study Results: Selected Sites along the Rio Grande from Bandelier National Monument to Elephant Butte Reservoir, New Mexico[b1] 

Bureau of Reclamation, January 2018

 

               A detailed analysis and discussion of flycatcher distribution and nesting along the Middle Rio

Grande in New Mexico. Monitoring found a 15% decrease in territories, finding 302 territories

led to increased dominance of tamarisk in the reach and thus increased use of lesser-quality

tamarisk habitat for nesting.
