I am elated to announce that I saw my first spotted salamanders tonight during the spring migration on Snow Pond! In my final weeks at the Concord Monitor, I connected with a local biologist, and have since been receiving emails updating me on various wildlife events in the area. Today, I received an email titled, “Tonight is the night!” She was referring to the annual spotted salamander migration to lay their eggs in nearby vernal pools, and then return to their home in the woods. Salamanders make a migration en masse when the temperature rises above 45 degrees AND it’s wet out.
Since Snow Pond is surrounded by tons of water, I figured I’d take my trusty flashlight out and brave the weather with my camera in hopes of spotting one of these elusive creatures. I was lucky enough to find three spotties making their way back to the woods, along with a few red-backed salamanders and tons of spring peeper frogs. Absolutely thrilling!

4/23/12 update – My photos made the front page of the Monitor, and the editor did a lovely interview about the shots too! Very cool!
Here was my first sighting! Despite the challenge of photographing with a flashlight (and in the rain!), it’s a good thing these salamanders make their migration in the dark when few cars are out on the roads. Roads alter the habitat of many species by fragmenting their landscape and making it difficult to find mates, lay eggs, and survive oncoming traffic.
Spotted salamanders are found in deciduous forests throughout the midwest and eastern United States. They eat earthworms, snails, slugs, spiders, millipedes, and other insects. Predators of spotted salamanders include skunks, raccoons, turtles, chipmunks, squirrels, opposums and snakes.
These salamanders have blueish-black or dark gray skin and two rows of yellow spots on their back. No two salamanders have the same spot pattern.

Spotted salamanders will return to the same body of water to lay their eggs year after year, and will travel up to a quarter of a mile to do so. In the wild, they can live up to 20 years.
The spotted salamander is categorized as a “mole salamander”. These types of salamanders have wide, protruding eyes, prominent costal grooves, rounded tails and bulky arms.
These salamanders can grow up to 9 inches long, although most are 6 – 7.5 inches long. By contrast, the largest salamander in the United States is the endangered Hellbender, which can grow up to 29 inches in length and weigh up to 5.5 pounds!

A red-backed salamander makes it’s way across the road. Red-backed salamanders are very common, and are known as a hardy species. They are often kept as pets.
Spotted salamander populations are considered stable throughout their range, but their skin is very sensitive to changes in the environment. Rising water acidity in certain habitats is negatively affecting them in the northeast.

And last but not least, here are a few quick videos I managed to shoot of migrating spotted salamanders. Please excuse the poor focus and exposure!
