Just the other day Deb and I were out taking a walk in the desert south of Tucson. The Freeport McMahon company (copper mining), has provided the locals with a natural birding area of desert habitat.
At this time of the year, the popular kid of the month would have to be White Crowned Sparrows. They are floating in just about all the cactus and ground cover, picking away at seeds. The juveniles are very bland looking and the easiest way to ID them is to see their close approximately to the adults. Bingo....you have them. Even if you are wrong and it ends up another type of sparrow, 90% of the time you are right. So just learn to live with it, I suppose.
We also birded Arivaca which is the image above. Just outside Arivaca lies the Buenas Aries National Wildlfe Refuge. Their are several locations to the Refuge and one of them is south of Arivaca and is where the refuge is attempting to introduce the Masked Bobwhite Quail which has most likely been extinct from the United States since 1900. But scientists have been working at Buenas Aries since 1985 attempting to introduce these back into the wild. Currently they have been unsuccessful in doing so due to the range, habitat loss....etc. If you are lucky, you might be able to view them as they are brought in from Mexico (imported birds, go figure) but....they are in an enclosed pen and I have never seen them.
But the good news is that if you are unlucky in your quest, your best bet is to head on down the road aways to the La Gitana, which just happens to be the oldest bar in the oldest continually inhabited townsite. So best to hightail it back to small community of Arivaca and seek out the tacos available at La Gitana Cantina
