Join us at the Nature Museum on Friday, April 14, at 10 am to kick start the City Nature Challenge! Learn from our scientists what species you might find outside, get tips for using iNaturalist and use our free wifi to upload your observations. Chicago is one of 16 cities participating in the City Nature Challenge 2017 (April 14 to April 18, 2017), a friendly competition to see which city can document the most nature using the iNaturalist app. Participating is easy. All you have to do is: 1. Download the free iNaturalist app to your mobile device (available for Android and iPhone) 2. During April 14-18, take photos to make observations of plants and animals in your neighborhood, a park, your walk to school or work, alleys, downtown - anywhere you find nature 3. Upload your photos to iNaturalist 4. Learn more as the iNaturalist community helps identify your observations. You don't even need to know the name of the plant, animal, or fungi you photograph. The iNaturalist community will help you identify it! Any observations made in Cook County and uploaded to iNaturalist between April 14 and 18 will be added to Chicago’s total!
