This page is a work-in-progress just as the studies and listings of animals at Casa Grande Ruins National Monument continues as a work-in-progress.
Some of our park visitors have discovered that the desert can be a great birding hotspot. We have been lucky in having talented photographers forward pictures they have taken at Casa Grande Ruins so that we can share them with you. You may see these wonderful gifts on the birding page. If you have visited the park and have pictures to share, please let us know. You are always welcome to use the 'contact us' link on each page.
Of course there are mammals within the park boundaries as well. The most abundant, and quite the crowd pleaser for most of the year, is the round tail ground squirrel.
Did You Know?
Burrowing owls are unique among birds because they nest underground in existing ground squirrel, coyote, and badger burrows. They are also commonly associated with humans and will frequently nest in burrows along irrigation ditches, canals, and even in people’s yards.
