These two birds are infrequent visitors to Orange County however I was able to capture images of both of these striking species at Joshua Tree National Park on the Pine City Trail on April 24, 2013. For those unfamiliar, Joshua Tree is approximately a 2 hour drive from Orange County.
A shortcut to the Black-throated Sparrow and Scott’s Oriole gallery page can be found here:
The Pine City trail was a most desolate location in the park. This particular hike lasted an hour in each direction from the foot of the main trail. Below are several photos along the way to the rock formation. We also encountered a Scott’s Oriole.
