When Wood Frogs begin calling, what weather condition might still be present in northern regions?
Answer
Snow may still be on the ground or ice may still be breaking up on water bodies.
Wood Frogs are among the very first amphibians to become active in the spring, coinciding with the earliest thaw signals. This early emergence is critical for exploiting temporary water sources. Consequently, when their characteristic calling chorus begins near breeding aggregations, it is common for residual winter conditions to still be present, meaning observers might still see snow on the ground or witness ice actively breaking up on the shallow pools they are using.
