There have been about 7 reports of the species in Utah, although there is only one "officially accepted record"--but you know my thoughts on that. This secretive sparrow can be very hard to detect as it is--secretive. On the occasions I have come across this bird they have always been seen briefly as they moved through low brushes and grass. This individual gave me about 10 seconds perched up on the wire, after hopping from the edge of a dirt road--and before disappearing into a field with lots of low shrubs and grasses.
It's been a great year thus far with some really good birds showing up around the state. Here is a link to the article in the tribune:
