Explore your Neighborhood

  • Take a walk and see what other organisms share your neighborhood. Make sure to practice social distancing by keeping space between people of at least 6 feet. Be considerate of others and cross the street, if necessary to maintain distance. (Always be mindful of traffic and safety.)
  • Look up to spot birds sitting in trees or on powerlines and telephone poles.
  • Look down to find insects, crawling on the pavement or underneath leaves.
  • What else might you find?
  • Visit your local park or regional park. Make sure to practice social distancing by keeping space between people of at least 6 feet. Look in the grass, on plants, under benches and tables, and up in the trees. How many different species will you find?

Part 1: April 30 – May 3, 2021

The City Nature Challenge is an international celebration of biodiversity in and around urban areas.
