I have to agree.  It is not as if brush birds are all that unusual!

There are birds, other than rails, here in California that generally
behave exactly as you described the rails behaving (even to being
reluctant to actually fly - the main difference is that they are
not "thin as rails").

In fact I am going to say the opposite.

If _Nanosaurus_ didn't frequent closed cover environments, I will
eat my hat.  And I am fairly certain that at least some of the smaller
pachycephalosaurs were forest animals.
