Salamander Massacre?

I was coming back into the house from my morning bike ride this morning and noticed something on the front step that looked a bit unusual.

On closer inspection, I realized it was a small dead salamander. Then I noticed another, even smaller one on the other side of the step. Weird.

I assume they were babies as the adult salamanders I've seen before have been a few inches long and these were tiny.

I moved them next to each other and put my key next to them for scale to take the photo below.


No idea why baby salamanders would be on my front step and why they'd be dying there, hopefully it's a one off occurrence, though I assume it must mean there's a nest (or the salamander equivalent of a nest) nearby.
