Field Marks and Identifying Characteristics: |
The bird was about the size of a Mallard. It was with a group of C.moffitii -
difference in size between the bird and them was remarkable. Bird had a very
tiny, black bill. Steep culmen. Round head - not a trace of squarishness or "boxiness".
Mantle was overall brown, undertail coverts white. Head and neck black with
classic white chin "strap". No color differentiation between its dark
breast (which in the right light had a purplish sheen) and its flanks - both
were brownish. This bird had a very narrow but easily seen white neck ring. (see photo) |
Song or call & method of delivery: | None heard |
Behavior: | Paddling in shallow pond along with Canada geese and several species of ducks. It also flew at one point along with the Canada geese and the size differences were noted. |
Habitat: | Shallow pond surrounded by mixed grasses and upland desert shrubbery. |
Similar
species and
how were they eliminated: |
No Canada Goose is this small, not even the "lesser" Canada Goose. No other Cackling Goose has as dark a breast and so round a head. Size of bill was extremely small. |
Previous
experience with this & similar species: |
First sighting for me and for many others in the field trip group. One group member had seen one earlier this year. I've seen two forms of Canada Goose but never a cackler. |

Additional Comments: | I have spent a good amount of time looking at photos and reading up on Canada and Cackling geese and felt I'd learned enough to be able to identify this bird 100%. I don't know how to attach the photo of the bird to this form so will send it separately to Milton Moody via e-mail. The photo was taken by Deedee O'Brien. She gave me permission to send it as long as I named her as the one who took the photo. The minima is the bird in front of photo. |
