There are several sorts of loons that are found in Alaska in early June. However, only one of these, the Red Throated Loon is found in the smaller ponds. This is, as I have been told by our tour guide, because the Red Throated is lighter than the other loon and can simply take flight from a standing (sitting) start. The other loons, being heavier, need a "runway" to get up to speed before they can fly. This opens possibilities for the Red Throated in feeding and nesting in the smaller ponds that the other loons do not have.
