Mark F Posted April 2, 2020 Share Posted April 2, 2020 I saw these two terns today by San Francisco Bay. I think they are Common and Forster's, but I'd sure like to hear what you think. Many thanks. Quote Link to comment Share on other sites More sharing options...

AlexHenry Posted April 2, 2020 Share Posted April 2, 2020 The first one is Forster’s 1 Quote Link to comment Share on other sites More sharing options...
AlexHenry Posted April 2, 2020 Share Posted April 2, 2020 Second one could be Common but I’m not sure. Upper side of primaries is pretty pale which is weird but looks like red feet and bill and dark outer webs on tail feathers. Common is relatively uncommon/rare 1 Quote Link to comment Share on other sites More sharing options...
Mark F Posted April 2, 2020 Author Share Posted April 2, 2020 Thanks to both. I thought that the white forehead on the first indicated non-breeding Common, but I see that’s not the case necessarily. Quote Link to comment Share on other sites More sharing options...
