Outline of proposed changes
Plan for editing:

For Taxonomy section, use all three sources to describe the evolution of the chestnut-backed chickadee as a genetic species and also in its geographical range/ habitat. Use source 3 to include descriptions of each subspecies.

Use source 3 to expand upon the behaviors listed above; use source 2 to expand upon the description of the chickadee and variation in its coloration throughout its range.
