Besides the neat black cap, what combination of colors describes the back and underparts of the Sabine’s Gull?
Answer
Gray back and white underparts
The delicate appearance of the Sabine’s Gull, *Xema sabini*, is characterized by several distinct markings that help birders identify it. Specifically, the plumage features a neat black cap contrasted sharply against a gray back. The lower half of the bird, its underparts, are white. Additionally, the tail structure is notable, being forked. These specific coloration details, especially the gray back and white underparts paired with the black cap, are key identifiers for this species when observed during its migratory or breeding phases.
