Anyone for gulls and terns

It always seems that whenever I get to gulls and terns I become very serious.  In earlier days and posts I might not have even bothered to include gulls.  But ever since I became the proud owner of The Gull Guide North America  (2024) (it can be purchased for $29.85 from Thriftbooks) by Amar Ayyash and also heard him give his Keynote Address, Man and Gulls at the BWIAB conference this past Mother's Day, I feel differently about gulls.  That's a good thing.  My review, from last October, of Amar's book is here.  The You Tube Man and Gulls link here is Amar's Keynote Address at a different conference (1 hr, 5 mins long). 


Above and two below:  Mew Gull (Larus canus)?  No.  Short-billed Gull (Larus canus)?  Yes.  Common Gull (Larus canus)?  Yes.  Here is the Common Gull (Europe) and Short-billed Gull (North America).  As already discussed, what's in a name?  I'm surprised to write this, but I think it was my favorite gull of the trip, even though this is not what I was expecting going into the trip.  I think it's a very pretty gull.  I included the not great photo above, because I like photos of gulls on unexpected perches.  These are the only Common Gull photos I have and were taken in the same location as the Siberian Tit.  




Above and two below:  Little Gull (Hydrocoloeus minutus)

I thought this would be my favorite gull of the trip and I do like it very much.  We saw hundreds.  I took a lot of photos and tried hard to get good photos.  I selected these randomly.  The dark eye in the dark head conspired against me with so many different birds on this trip.  Of the three here, I think I like the middle photo best - a little gull flying past a nesting Whooper Swan (Cygnus cygnus), of which we also saw many nearly everywhere.




Above and below:  Black-headed Gull (Chroicocephalus ridibundus), even though its head is brown.

You can see the tiny insects on the water's surface that Little and Black-headed gulls were feasting on.  I think of this gull as being like our Ring-billed Gull - it's everywhere, even in parking lots.




Above:  Black-legged Kittiwake (Rissa tridacyla) colony occupying an abandoned - by humans - fishing hut of some sort in Båtsfjord.  They occupied every ledge or other spaces on all sides of this building.  They were a raucous bunch.

Great Black-backed Gull (Larus marinus).  We saw it often.

I have always liked terns but find the Sternas difficult to identify.  A couple of years ago I added Cameron Cox's Terns of North America: A Photographic Guide (2023) to my bookshelf (currently 30% off with Princeton).  Earlier this spring I confused a Forster's Tern (Sterna forsteri) for a Common Tern (Sterna hirundo) on this blog and I was, after a few weeks, corrected by the eBird moderator.  Now I think Common Tern and Arctic Tern (Sterna paradisaea) are a more confusing pair.  I think the 2nd edition Birds of Europe doesn't really help my confusion (pages 200-201) although I have considered that these two terns may have slightly different features in northern Europe.  I pulled Cox's book off the shelf to write this entry.  My photos aren't dreadful, but none are particularly good either.   


Two photos above and one below:  Common Term (Sterna hirundo).


The wide, white leading edge on the anterior wing is a key feature for me.  Arctic tern also has this, but it is not so prominent.  Having pointed this out in these photos, I can't find a photo in Cox's book also showing this.  The bill is also darker red than I would expect it to be. 

                 
Above and below:  Arctic Tern (Stern paradisaea).

This bird is from a noisy flock that were wheeling around the rocks in, (location Persfjord(?), in Norway.   I feel very comfortable with this ID because in these final days of the trip, we were only seeing Arctic Terns.  Also, I had the presence of mind to open Merlin and confirmed their vocalizations.

This seems like a very academic post to me.  I am completely unqualified to write a scholarly blog post about gulls and terns.
