The overall silhouette is rectangular, and it has a round head. The bill is short and stout. The wings are relatively short and rounded, with no significant wing patches or wing bars. The tail is short and rounded, which is typical for many insectivorous birds.\n\n2. **Color Pattern**: The bird has a mix of colors, including shades of blue, orange, and brown. The head is blue with a hint of orange on the throat and chest. The wings have a blueish-gray coloration. The tail is brownish-gray. The underparts are orange-brown, and there is a noticeable white stripe running through the eye.\n\n3. **Behavior**: The bird is standing on a post and appears to be holding a nest-building material in its beak. This behavior is consistent with its筑巢活动, and it seems to be alone.\n\n4. **Habitat**: The bird is perched on a wooden post, which suggests a rural or suburban setting. The background is a green field, indicating an open area, likely a garden or a field.\n\n5. **Field Marks**:\n - **Head**: The head is blue with an orange patch on the throat and chest.
