Подробности наблюдения
A surprising number for so far inland and this far south. Number of individuals by age classes calculated based on overall percentages of each age class; 85% hatch year, 5% 2nd year-4th year (i.e. "subadult"), and 10% adult. We spent a large amount of our time here simply photographing Thayer's Gulls, so many (hundreds) photos obtained.
