Andy,

As one might expect, we have limited information on the movements of such a
secretive species as the King Rail. A general pattern in birds is that
natal site fidelity is typically low but breeding site fidelity is usually
much higher. One study in Maryland (where the species is a permanent
resident) showed that only one of 41 juveniles banded in the summer was
still present in December in the same marsh, suggesting that young rails do
disperse from their natal site. There are two reports of breeding site
fidelity (one from Maryland and one from Arkansas) where birds in
consecutive years nested with 16 m of the first nesting site. We also know
that rails show remarkable dispersal given their relatively weak flying
abilities. So, I doubt that the King Rails in Wells will give rise to a
breeding "clan".

Best,

Herb
