Las Cienegas NCA in Sonoita, AZ is 46,000 acres of open grassland with several roads allowing access to the many birds (and cattle...:) that call it home. This was my first visit, it took 3 hours for me to drive through with much exploring, birding and photography.
Clay-colored Sparrow. There were literally thousands of these throughout the conservation area.
One of the many cows that were free to roam as they wished.
A Dickcissel that popped up.
Lark Buntings were everywhere on my 1st visit and very hard to find a few days later.
Lark Sparrows were out in numbers on each visit.
Prong Horned Sheep, I only saw a few.
A dark Red-tailed Hawk along the road.
Swainson's Hawks were moving through in good numbers.
Another Swainson's Hawk as it perched on the post.
and finally Yellow-headed Blackbirds were seen in several locations.
