Couch's or Tropical Kingbird.
I assumed Western, but I took photos anyway to try and cinch the ID, yet looking at photos, it isn't that clear. Bill seems awfully big. No white on the tail edges (could have been lost) or tips. Silent.
I was looking at my Eddy County butterfly entries and realized I hadn't entered this old one that I had entered at https://www.butterfliesandmoths.org/sighting_details/912647
I recognized it immediately despite never having seen one before from looking at butterfly field guides
