I went out to Mile High Road this AM in a futile attempt to relocate the Lewis's Woodpecker. I think it has moved on. But there are tons of bluebirds, Townsend's Solitaires and such. Here are the juniper berries that they're gorging on.
All junipers are not equal. The above photo is the female One-seed Juniper, and below is the male, which produces tiny cones, but no berries.
This amazing plant can grow tap roots up to 200 feet long.
