As we say goodbye to April showers and hello to May flowers, you too can grow and bloom by taking part in the Philadelphia City Nature Challenge, a 4-day bio-blitz where cities worldwide see who can record the most wildlife. Besides being a fun challenge, this is also a great way to engage in citizen science and document our areas’ biodiversity. Between April 30 and May 3, 2021 (Friday-Monday), Philadelphia and its adjacent counties will see who can find the most species in their regions. The City of Philadelphia alone has recorded more than 325 species of birds. Numerous butterflies, including monarchs, live and breed in the city, and there are snakes, frogs, dragonflies, foxes, bats, and much more to experience in our area. The City Nature Challenge gives us a way to explore and document the biodiversity in the cities and suburbs we call home. In turn, it is helpful for science and conservation. If you are interested in joining in and helping Philly win, download the iNaturalist app (or visit the iNaturalist.org website) and start documenting the wildlife in your area. So, get ready to get out there and take pictures of any wild organism and upload it to iNaturalist.
