Field marks that point towards a Lesser white fronted as being one
of the parents:
1. The bill in the pale
2. White frontal shield goinghigh
3. Eyering
4. Yellow feet
5. Long wings
6. Size of the bird (clearly smaller than a barnacle)
7. Leg patch + brown colors (as in other ansers too)
The parentage of the Barnacle goose being one parent is suggested by
1. Dark on the bill (any branta)
2. Cheeck patterns and the dark eyeline
3. Lower limit of the dark coloration on the breast
4. Dark tail (any branta)
5. Patterns of the pale coloring on the primaries
