Did not vocalize.

|Habitat:||Riparian. Willows, cottonwoods, riverside brush.|
were they eliminated:
I immediately knew and recognized the species as a Magnolia Warbler on my first
look and did not need to truly "eliminate" other species. The color
configuration of a yellow belly, chest, and throat with black streaks on flanks
and partial black "necklace", along with the black mask, and white under-tail
coverts on a black tipped tail were obvious. Gray head. Olive back.
Expected species such as Yellow-rumped, Grace's, or possibly a Townsend's were eliminated by simple familiarity with those species. The field marks described above rule out these species.
Yellow-rumped have numerous variations and color schemes that could appear similar to a Magnolia at times, but not all of them together. No constant yellow from the throat all the way down. No mask or necklace.
A Grace's has a white belly, no olive in the back, no black mask or necklace.
A Townsend's would NOT have a gray head, although they have the black streaks on their flanks, not quite a "necklace" of streaks on their neck, as well as black on their face that could appear as a "mask".
Equally and potentially more rare species for Utah would be Blackburnian, Black-throated Green, Kirtland's, Prairie, Yellow-throated, Canada, Cape May, or Chestnut sided. Once again, the above mentioned field marks rule these species out as well.
this & similar species:
|I have seen this species in at least a dozen other states and countries at multiple different times of the year. I knew it immediately.|
|References consulted:||I use Sibley's and ibird on my phone most of the time.|
