On behalf of Kathy who sent in an email:-
I live in central Virginia, USA. On my windowsill eating breadcrumbs yesterday was a bird I cannot find anywhere. The body was approx. 7-9", rounded like a hen, black or dark grey with very noticable white spots all over wings and body. The beak was straight and bright orange, kind of narrow and not short, legs were brownish orange.
Any help would be appreciated. Thank you.
