Double-crested Cormorant vs Neotropic

Recommended Posts

Today. Augusta, GA. I don't believe Neotropic has ever been reported in Georgia. But on four of these cormorants from today, I am noticing a white edge bordering the gular. I can't find examples of Double-crested showing white like this. I understand the gular is square on Double-crested and tapered on Neotropic, but I'm not actually sure which it is on these. Any thoughts?

Probably Double-crested... juveniles are pretty variable in terms of coloration on the undersides... Neotropics are noticeably smaller and smaller-billed than Double-crested

I know...sad. I'm sorry I asked, but I had exhausted all other means of finding out.

The light lores and pale breast are good for juvi DCCO.

And solid orange bills.  Those seem to be more reliable than white next to the gular sac.
