Goose hybrid at Belmar Park, Jefferson?

[Max Miller]

Hi everyone,

I was out at Belmar Park yesterday afternoon when I spotted this goose among a group of Cackling Geese. These are the best shots I could get: unfortunately he never lifted his head while I was present. You can still make out black on his crown, the white cheek bordered by a little black, and the stark white neck speckled in spots by more black. My best guess is this might be a Cackling x Ross's or Cackling x Snow hybrid, but I wonder if anyone else has any other/better ideas?

Thanks!
