Adult geese are often seen leading their goslings in a line with one parent at the front, and the other at the back of the "parade". Like most geese, the cackling goose is naturally migratory, with their overwintering range being most of the U.S. (locally in Western Canada, the West Coast of the U.S. and northern Mexico). The calls overheard ...
The black geese of the genus Branta are waterfowl belonging to the true geese and swans subfamily Anserinae. They occur in the northern coastal regions of the Palearctic and all over North America , migrating to more southerly coasts in winter, and as resident birds in the Hawaiian Islands .
Barnacle geese frequently build their nests high on mountain cliffs, away from predators (primarily Arctic foxes and polar bears), but also away from their feeding grounds such as lakes, rivers. Like all geese, the goslings are not fed by the adults. Instead of bringing food to the newly hatched goslings, the goslings are brought to the ground.
Since 2002, though, a relatively small (1500-5000) number of geese spend fall and winter on the northern coast. Around late December, the geese wintering in the Central Valley begin moving north, and by mid-February, most of the Aleutian cackling goose population is located in northwestern California until they depart for the Aleutian Islands ...
The adult geese will fly down to the ground and then "squawk" up at their babies to try and convince them to follow. It doesn't always work, however, which means the adults can be up there for a ...
The old "lesser Canada geese" were believed to be a partly hybrid population, with the birds named B. c. taverneri considered a mixture of B. c. minima, B. c. occidentalis, and B. c. parvipes. The holotype specimen of taverneri is a straightforward large pale cackling goose however, and hence the taxon is still valid today and was renamed ...
The red-breasted geese will now be tracked via satellite. Scientist and conservationists alike hope that learning about the geese's migration patterns will lead to proper conservation and more aggressive policies in the geese's territory. Some prior counts have revealed a more positive discovery, noting an increase in the geese's population.
