Lucy's Warbler is unique in the following ways:
- It is our smallest warbler
- It is our only desert warbler
- It is a cavity nester (one of only 2 warblers that do this -- the other being the Prothonotary)
- It is our least colorful warbler -- plumaged in pale grey and white
These distinctive warblers were seen by the dam in Sabino Canyon in the Coronado National Forest.
John Graham Bell. Like other vireos, the Bell's also shows the yellow and green hues which are typical of the family.
Bell's Vireo is classified as "Near Threatened" with a huge decline (a staggering loss of two-thirds of its population) over the last 4 decades in its population. Loss of habitat has been the main contributing factor. Recent conservation efforts have been successful in helping this species recover; however, the Californian subspecies remains classified as "Endangered".
