Identifying Fowler's Toad vs. American Toad: A Visual Guide

 Identifying Fowler's Toad vs. American Toad: A Visual Guide

When exploring the great outdoors, you may come across various species of toads. Two common species found in North America are the Fowler's toad (*Anaxyrus fowleri*) and the American toad (*Anaxyrus americanus*). At first glance, they might look similar, but with a closer look, there are distinct characteristics that can help you tell them apart. This guide will walk you through these key differences.

Skin Texture

Fowler's Toad: Their skin is more heavily covered with warts than the American toad. Look for large, dark warts within the lighter background color.

American Toad: While also warty, the skin of the American toad tends to have smaller, more uniform warts, and a more uniform color.

Parotoid Glands

Fowler's Toad: The parotoid glands (large glands behind the eyes) are either not touching the cranial crest (a bony ridge behind the eye) or are only slightly touching it.

American Toad: The parotoid glands are usually in contact with the cranial crest, appearing to touch or even overlap it.

Coloration and Patterns

Fowler's Toad: Typically, Fowler's toads exhibit a brown, gray, olive green, or rust coloration with dark spots. Each spot usually contains three or more warts.

American Toad: American toads can also display a variety of colors, including brown, gray, or red. However, their spots tend to be smaller and contain one or two warts.

Belly Markings

Fowler's Toad: The belly is often white or cream-colored with few to no markings. If there are spots, they're typically sparse.

American Toad: The belly of an American toad is similar in color but usually features more distinct, dark spots.


Fowler's Toad: Their call is a long, harsh, and guttural waahh, resembling a nasally human snore.

American Toad: This toad's call is a sweet, prolonged trill lasting several seconds.

Next time you're out in nature and spot a toad, take a moment to observe these characteristics. Whether it's the texture of their skin, the shape of their parotoid glands, or their distinctive calls, each detail can help you distinguish between a Fowler's toad and an American toad. With this guide and your photos, you'll be a toad-identifying expert in no time!

Eastern Worm Snakes vs. Smooth Earth Snakes

 Eastern Worm Snakes vs. Smooth Earth Snakes In the underbrush and hidden corners of the Eastern United States, two secretive creatures slither unnoticed: the Eastern Worm Snake (*Carphophis amoenus*) and the Smooth Earth Snake (*Virginia valeriae*). Though both are small, non-venomous, and often mistaken for one another, several key characteristics set them apart. This post will guide you through these differences, providing a visual aid to identify these elusive snakes in their natural habitats.  Body Shape and Size Eastern Worm Snake:  This species is slender and typically measures 7 to 11 inches in length.
