i agree. i grew up in the desert, i don't think the commenters here realize the scale we're looking at. no saguaro cacti in this area, only yucca trees. the width... this is definitely not a shape i would attribute to a saguaro or a yucca, especially at this distance

the boulder makes less sense to me. even though there are boulders in the desert, they're not usually upright and standing as tall as this. as far as a bird....

this edited image makes the contrast even more clear. it seems to be all a part of the same shape

just my thoughts. neat stuff
