I updated my Madera Canyon map this week (a singing Scarlet Tanager - seemingly on territory - was the impetus).
Madera Canyon is one of the best spots in Arizona (and hence, the US) for birding - the list of rarities and specialties is too long to list here! Check the Tucson RBA for current birds.
Quick legend:
blue markers: public parking (with parking pass)
red dots: private lodges with publicly visible feeding stations
green line: county line (for you eBirders out there)
I've marked various trails and springs; click for names.
The Scarlet Tanager is currently (17-22 June 2012) being seen along the Kent Spring Trail (red), at the hairpin turn just before the first dot (Sylvester Spring).
