Subspecies: caerulescens
Laguna Janos close to the US border is one of the classic localities for wintering Snow geese in Mexico - several thousand gather here. The percentage of blue compared to white birds in this picture is a realistic one. I saw about 100 blue and 13000 white birds! The birds in the background in the upper left corner are Sandhill Cranes.
Subspecies: caerulescens
Blue and white old birds taking landing. Blue birds apparently always belong to the 'Lesser' group which lives in the western part of North America. All the birds at this locality most likely belong to this group, since the Atlantic group 'Greater' normally only reaches Mexico at the most northeastern corner.
Subspecies: caerulescens
This blue bird has a classic appearance, but they do show much variation, as shown by the adult on the left side in the background. Also here a few young birds with black bills.
Subspecies: caerulescens
Same young bird to the right as seen in 1364. The gray blue wing coverts are beginning to show, and one perceives how the belly is about to turn brighter, and there this bird will probably not end up to look like the adult bird it was seen with in 1364. To the right a young white bird can be seen for comparison.
Subspecies: caerulescens
Of course there are much more to say about these white geese than proclaiming that they are unmistakable. Am not sure how the 'Greater' birds are separated from 'Lesser' birds apart from size? However the size, the long bill and the prominent 'grinning patch' all make it easy to eliminate Ross's Goose from the equation in this case.
Subspecies: caerulescens
Here two young white birds behind an adult blue. Compared to 1373 this adult shows more white between the legs and on the thigh. The young whites show no variation whatsoever.
Subspecies: caerulescens
A semi blue adult in contrast to all the whites and the large flock of Sandhill Cranes further in the background - they also use the lake as a wintering site.
Subspecies: ?
Adult blue morph. Looks good and healthy without banding, but all snow geese in Denmark are considered of non-wild origin. Yet. Was gone the next day. Swept away by the large barnacle wave passing through Amager in these days.
