[cobirds] Prospect Ponds Natural Area, Fort Collins (Larimer) geese on 1/26/2019

In the pond just south of Prospect Road on the east side of Sharp Point Drive by the feedlot are a few thousand geese currently.  Most are Cackling Geese (75%?), a few hundred are Canada Geese plus the following:

1 White-fronted Goose

 

3 Hybrids. 
 

I would appreciate any comments as to parentage of the hybrids.  It would be nice if we could start a repository (CFO webpage?) for hybrid photos, especially when there is reasonable certainty of the two species involved.  The field guides do not cover this issue very well and I almost think we need a separate field guide devoted to hybrids (all taxa, not just waterfowl), at least combinations that are distinctive and occur with regularity.  I know several birders among us have a considerable number of hybrid photographs and they would be very useful if archived, labeled and made accessible.  Just a thought.
