Nashville Warbler, Larimer County,

[Glenn Elmore]

Yesterday a group led by Nolan Bushnell walked the Well Gulch Nature trail in Lory Park on the NW side of Horsetooth Reservoir. 

On that walk about 2/3 of the way up to where the trail splits everyone watched a pair of Nashville Warblers constructing a nest, in a tree right on the trail.   Photography was difficult because the birds came in from the 'back side' and went straight into the bottom of the construction project. and the angle from the ground difficult, however ,Nolan and others confirmed ID as the pair were entering/leaving by the rusty/red patch on the males' crown.

Correction, I should have written that our guide was Nolan Bunting from Field Ornithologists at Colorado State University.
