Re: [Maine-birds] King Rail questions

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

  King Rail questions

For the second year KIRA have successfully had young here in Wells, Maine. On 6/19/2018 a nest with 11 eggs was found. On July 3^rd and 4^th , 7 chicks hatched.

Will the young migrate back to the same place where they were born?

Also, after they are old enough to breed will they return to the place of their birth with a mate that is not their sibling, or will they mate with their sibling?

I saw online that they can start to breed at one or two years of age, so could the marsh this year, or next get invaded with lots of KIRA?

Thank you
