Sounds like some out of state birders saw a Yellow-throated Warbler at Pueblo Nature Center, Pueblo County this morning, 19 April, in Cottonwood trees.
Hopefully a singing male will return at Roselawn Cemetery or Mineral Palace Park soon. I hope to get to Roselawn later this week.
This is 2nd eastern migrant warbler this spring in Colorado, I heard about Northern Parula yesterday from Higbee Valley Road in Otero County. Warbler season is on!
