Gulls (part 2) at Westmoreland Park in Portland, OR (01/23/11)

Ok, here are a few young ones …

This is a bird that I pointed out to Art Clausing who I ran into while birding the park for about 45min. I still believe that this is a first-cycle Thayer’s Gull.

Now, this bird, on the other hand, I was not able to id as a Thayer’s. First off, it was rather large compared to its buddies around it. While the bill is not huge and might fit the large end of Thayer’s, look at the primaries: They are pretty much the same color as the rest of the bird. I’m pretty sure, that this bird has Glaucous-winged in it.

This bird was the reason for my trip that day, a first-cycle Glaucous Gull, first reported by the Hinkle twins. Watch for the bicolored bill and crisp demarcation between the black and pink areas in the bill. A no-brainer. 

This diminutive bird looks perfect for a first cycle Thayer’s Gull.

I’m going to finish up with another adult. What’s wrong with calling this a Herring Gull? The smudging on the head/neck just looks real olympic to me. This bird sure looks like a Herring x Glaucous-winged Gull.

  1. The gull photo after the Ruddy Turnstone looks more like a 1’st year Mew Gull. Bill to heavy and short for a Thayer’s/
