how heavy are cacklers.
From the BNA account,
On Yukon-Kuskokwim Delta, AK, females reach maximum mass of annual cycle at prelaying (1,890.0 g ± 9.0 SE; n = 4), exceeding that of males (1,871.0 g ± 38.0 SE; n = 5).
Y-K birds are wild cacklers.

If you're interested in cacks, I would suggest trying to find a copy of Management and Biology of Pacific Flyway Geese. It's a nice set of papers.
i dont under stand anything you wrote.
Clint has posted you results from reserch done by Johnson which describes weight and other key measurements of the geese including length of beak, main toe etc.
Overall the paper is stating that the maimum weights for the geese before breeding commences is;
Males - 1871 grammes (1.87 kilos)
Females - 1890 grammes (1.89 kilos)
Hope that helps you.
Quote:Pete most americans don't know the metric system so I did a fast & dirty conversion in bold
thank you that helped.
i know pounds.
It's really sad that the metric system isn't better integrated into American schools.
