A dragon with level 4 doesn't automatically means they're a baby, in Expansions, you can get rewarded with Adult Dragons but are in Level 1; you can also use the Adult Age Up to age up a dragon which unfortunately keeps it at its current level instead of also increasing the level.

The Monstrous Nightmare in the icon is an adult given the snout's size (baby Monstrous Nightnares have much smaller heads), implying Ruffnut used an Age Up to age him up to Adult while he was at Level 4.
