The terns were still in the process of building the nest and I saw them bringing in nesting materials, there weren&#8217;t any eggs in the nest at the time.

Both sexes incubate and they are monogamous.<\/li>\n<\/ul>\n<p>The differences in breeding and nonbreeding plumage of Forster&#8217;s Terns is enough that some bird watching and bird photography
