Herring Gull
Larus argentatus
11 Apr. USS Baranot Calvert, St. Canada
5 miles S. of Queen Charlotte Island.
When making a landing on the water this gull will glide slowly down to the water into the wind. When about 2 ft above the water where it desires to alight, it will lower its legs and fan its tail downward spreading the tail feathers wider. This tends to make the bird slow to almost zero forward speed. The long axis of the body tips upward as the bird stalls out.
The downward dropping of the legs is continued until the legs swing forward a little. The feet are spread, toes raised so that the hallux hits the water first. The web of the feet act as shock absorbers and the bird bodily settles onto the water. The wings are undulated rather quickly just after the
