Mount Lemmon provides great birding for a variety of warblers, typical mountains birds, AND for nesting hummingbirds. Rose Canyon Lake on Mount Lemmon provides perfect hummingbird habitat. so it is not uncommon to see hummers and even find their nests.

Soon mom came zooming in, sat on an adjacent branch, and started feeding the little guy. Here is a series of photos I took of the event:
