Do You like Observing Nature? Then make your observations count this weekend. Every year on the last weekend in April, the Greater Phoenix Area participates in the City Nature Challenge (CNC).The CNC is a family friendly worldwide competition among cities to see whose residents can spot and identify the most wildlife. Come to the Peoria Main Library on Friday afternoon or Saturday morning for a training on how to download and use the free app iNaturalist. Then we will take it all outside to “BioBlitz” Peoria’s City Hall campus and join in the CNC!
