Notas sobre o média
Showing the two ICGUs that had been in flight after landing on the frozen pond surface. The kumlieni with the white primaries is to the right center, and the other ICGU-thayeri is at the front to the right. The shape of the two birds, bill size and wing projection is basically identical. The kumlieni had whitish primaries, lacking any dark coloration, that were the same color as the mantle, and much lighter than those of the immature HEGU behind it and the thayeri in front. The ICGU-thayeri had brownish primaries that were darker than the mantle.
