Observation details
Continuing bird. Digiscoped photos to be submitted later. Slender, long-tailed cormorant compared to chunkier, shorter-tailed double-crested who offered side by side comparisons. Neotropic half the size of the double-crested when seen perched together. Excellent scope views enabled me to study bill shape and size, gular pouch shape, size and amount of orange, and gape shape of both species. Gape of Neotropic much more pointed, in v-shape, whereas double-crested seemed to be more squared off. Both species showed some white at border of gape so this may not be a useful field mark. Bill more slender than double-cr., with much less orange in gular pouch. The individual double-crested I studied in the scope had orange lores extending to the eye. This feature was lacking in the neo. Neo also seems to have longer, more slender neck. This particular bird shows some molt in the breast feathers, giving it a somewhat mottled black and white appearance.
