Things are hopping at the Saint Louis Zoo North Campus! Remote acoustic recorders are collecting wildlife sounds to help us document and better understand the local wildlife populations. So far this season, our recordings have documented currently 4 frog/toad species (spring peeper, Western chorus frogs, cricket frogs, and American toads) living in our ponds and lakes. We will be sharing those recordings throughout the day!
Help us build an auditory library of frog and toad calls using an app! Anyone can participate at any time. The information gathered will help researchers track where frogs and toads are being spotted in the St. Louis area. Click here for more information. #SaveTheFrogDay #BringTheStlZooToYou
A common and very distinguishable sound this time of year is the American toad. With a long trilling call, these toads often gather around ponds in the evening to breed and are often found at the fountain by the South Entrance of the Zoo.
Cricket frogs are small, bumpy frogs that start calling in March. Although they are found throughout Missouri, their populations in other states are declining. Their call sounds like two pebbles being clicked together, or “gick-gick-gick.”
Using their prominent adhesive toe pads, gray tree frogs are often found in tree holes and perched on leaves and branches. In Missouri, gray tree frogs become active in April. Males gather and call at swamps and pools that are usually devoid of fish. The call of the gray treefrog sounds like a musical birdlike trill. #BringTheStlZooToYou
