觀察細節
Two of these, one photographed, were originally identified as Double-crested based on their prominent orange supraloral stripe and the shape of the rear border of gular pouch that was rounded, more closely matching Double-crested. They also appeared to be clearly larger than the third bird with them, a Neotropical Cormorant. Marshall Iliff placed the species in the review queue as a misidentified Neotropic Cormorant based on the photos, He pointed out that (1) the bird has a steeper forehead angle at the bill, (2) it has a gular pouch that appears rounded at the rear, more typical of Neotropic, (3) Neotropic can also have a prominent orange supraloral stripe, and (4) Double-crested is unusual inland. I disagree with his conclusion that the bird photographed is a Neotropic Cormorant. The other five members of the Belize review committee also disagree. We have never seen a Neotropic Cormorant with such a prominent orange supraloral stripe, although such may be possible. Also, we have seen a number of immature Double-crested Cormorants in Belize with a more rounded hind border of the gular pouch than is typical in adults, which usually have a squared off rear border. In our experience, Neotropic almost always has a sharp angle at the base of the gular pouch. Also, these two birds were clearly larger than the third bird with them, a definite Neotropic. While Double-crested is only occasionally encountered inland, it is not entirely unexpected, especially at locations within 10 miles of the coast.
