Large juvenile Gull - Southern Lake Michigan U.S. (1 Viewer)

chipperatl · Dec 10, 2018

I posted this on Whatbird also, and received a single response of possible thayerii. I was about 300-350 yards away at a 40 degree angle from the wall. The wall is about 20 feet wide. I was shooting a 400mm f5.6 for these shots. Two different GBBG in these shots. Gull is on the left of one GBBG, and then to the right of a second GBBG in others. Also a shot of it near other HERGs.

Not sure if a thayerii would size-wise match up this close to a small GBBG, or if it is just a light HERG? Bill seems rather thin. Pics taken on December 8th, 2018. Thank you for any help with this.

Strikes me as a Herring Gull with a bill on the smaller side (lots of individual variation, with females tending toward smaller-billed). The primaries look too dark for Thayer's and don't appear to have any pale edging.

Thank you. I think Occam’s Razor supports this. Dang beefy HERGs.
