Tucson Bird Alliance Field Trips at Rio Vista Natural Resource Park

The list below notes the species observed on birding field trips at Rio Vista conducted by Tucson Audubon Society (now Tucson Bird Alliance) between May and November 2024. Leaders were Gary Bachman and Scott Olmstead. The observations were of birds seen within the park and surrounding properties, including in the Rillito and in the air. Most observations were by sight; some were based on calls or songs. Most field trips were held between 6:00 and 9:00 a.m. The observations are compiled on eBird and do not include other eBird lists submitted for the same location. This is not a complete list of birds found in the park. For instance, it does not include owls or nighthawks or other birds not typically seen in the morning. However, the eBird bar chart lists all species observed at the park and provides an indication of what you might expect to see in any given month.

This list will help park visitors to be aware of the seasonal and permanent residents that they might observe, as well as the more common residents and unusual visitors.
