觀察細節

Group size is educated estimate (including rough ratio of fledgling to adult) based on multiple counts. However, they were for the most part distant and moving. Young were all flying well. Some were still begging to adults. Many were seen diving for their own food. (But not necessarily catching anything). Two mobbed a Bonaparte's Gull subadult, for unknown reasons. An adult dived and scolded me for a few seconds when I first approached the sand bar on the other side of the Creek where I then noticed juvenile terns about 80 m away. Unclear if these are all from the small local breeding population (recent years assumed less than six adults but this year 15-20 recorded by other eBirders nearby earlier in the year) or included some visitors from presumably farther north up Lynn Canal.
