Common vs Pacific Loon

[Robert Righter]

Hi

An average  Common Loon is about twice the body size of a Pacific Loon. Usually in our reservoirs, at this time of year, there are many Western Grebes and  just based on body size alone they are about equal  to a Pacific Loon. With just the right juxtaposition of a Common or Pacific Loon with a Western Grebe could also assist in a Common/Pacific Loon identification.
