Detalles de la observación
4th North American record. Found simultaneously by Chuck Hathcock and Lizzie Diener perched on playground equipment at Lake Andrews. First Called a Brown Shrike, Sulli Gibson suggested we think about Red-backed Shrike. Photos do show barring on the back which is good for Red-backed Juv, and first winter birds. The Brown Shrike should have a plainer less barred brown back in first winter. Also the mask seems brown, not as black as in a Brown Shrike. We were sent some field guide information showing a much shorter outer tail feather in Brown Shrike. We have one photo taken by Mike Hill, showing that the outer tail feather R6 is just shorter than the R5, which fits with Red-backed. Other documentation photos taken by John Diener
