Identify Creatures On City Streets

It can be easy to overlook city-dwelling animals that can be found in the most unexpected places. #StreetCreatures can help urban nature lovers notice the plants or animals they’re not seeing right away.

How does it work? Every Friday morning, Kelly Brenner, a naturalist from Seattle, posts clues about plants or animals that live in the city. The feed’s followers research the clues and message Brenner with their answers until she formally posts the results at 2 PM and talks about each of the clues. followers have fun while they learn from each other and from Brenner about the wildlife they aren’t noticing at first glance.

Is It A Cougar?

Cougars generally keep to themselves. They’re not often spotted unless they are attacking their prey, they’re hurt, or they’re on a wildlife motion-sensing camera. The rarity of spotting a big cat is one of the things that makes the picture-based feed, #CougarOrNot so much fun.

The game couldn’t be more simple. Every Friday at 11:30 AM, Denali National Park’s Kaeli Swift posts a photo of a possible cougar sighting. Followers weigh in on whether or not they believe the cat caught on film is an actual cougar. When Swift finally posts the answer she talks about the photo and gives details about the big cats, their habits, and their environment.

Hidden Lizard Search

This fun, two-part challenge helps followers understand and identify lizards. The quiz starts on Tuesdays at 2 PM when Ph.D. student Earyn McGee posts a photo of a lizard complete with a couple of details on the animal and using the hashtag #GuessThatLizard. Sounds simple, right?

Things get a little more complicated on day two. That’s when McGee posts a second picture of the lizard’s natural environment with the hashtag  #FindThatLizard and tells followers how many of the animals are resting in it. Viewers scan rocks, plants, and other aspects of the terrain looking for them. The hunt can be challenging but it also imparts a wealth of information about the cold-blooded creatures. The answers are posted on a third hashtag which is appropriately named #FoundThatLizard.

Next-Level Bird Identification

One of the easiest ways for amateur naturalists to get started in their hobby is to take time to identify birds. It just takes research, binoculars, quiet, and some time to find the right bird. #TrickyBirdID makes spotting fun, teaches followers about types of birds to look out for, and reminds them that birds aren’t always posting neatly in plain sight, waiting to be photographed for your social media feed.

The feed is run by National Audobon Society staffer Jason Ward. HIs goal is to teach interested members of the public the basics of bird identification. He generally posts a photo on Mondays, Tuesdays, and Wednesday evenings at 8 PM. About a half hour after making the first post, he begins to share some of the winning responses to the public and to explain the photo and the bird identification process in more depth.
