Observation details

I originally reported 7 Neotropic Cormorants, thinking that in addition to the 2+ independent perched birds mentioned above, a group of ~5 nesting birds (1-2 parents and 3-4 nestlings) kept catching my eye as likely Neotropic. However, I'm no longer confident about that. I was making that judgment primarily based on size and shape. At least one definite Neotropic was perched nearby, and I sometimes thought they looked closer in size to the Neotropic than to surrounding Double-crested. However, I found that I sometimes got confused and mixed up these birds with individuals that, upon closer inspection, were definitely Double-crested. So I think my impressions of size were inconsistent, and distances to the birds may have been difficult to judge. I think part of what confused me was the unusual-looking facial skin of these birds, as shown in these photos—it didn't look like a match for typical Double-crested or Neotropic. But I don't have much experience with Neotropic, nor do I have much experience with nesting cormorants of any species, so I don't really know what nestling Double-crested look like either. I think the birds in these photos may just be nestling Double-crested, but I'm still not sure.
