All of the Passeriformes are altricial, and many nest on the ground, 
including birds, including most of the larks that are highly 
terrestrial.  In fact, with Passeriformes outnumbering all other 
birds put together, I would suspect that the number of ground-nesting 
birds with altricial young is quite high.

There are also ground-living woodpeckers, pigeons, and others besides 
those mentioned, including some that nest there (or at least on 
ledges or in crevices).
