Key Differences Between White-winged Doves and Mourning Doves
Here’s a comparison highlighting the main differences between White-winged Doves and Mourning Doves:
Body Size
- White-winged Dove: White-winged doves are noticeably larger and more robust than mourning doves. They exhibit a bulkier appearance with a squared-off tail. These doves are often found in arid and urban areas of the southwestern United States and Mexico.
- Mourning Dove: Mourning doves, in contrast, have a slimmer and more streamlined body. They possess long, tapering tails that contribute to their distinctive appearance. Widely distributed across North America, they prefer varied habitats including both urban and rural environments.
Tail
- White-winged Dove: The tail of the White-winged Dove differs notably from that of the Mourning Dove. White-winged doves have squared-off tails, giving them a distinctive and angular appearance.
This tail shape is one of the key features that set them apart. When they take flight, their squared-off tails are particularly visible, contributing to their identification. - Mourning Dove: Mourning doves are recognized by their long and graceful tails. These tails are tapering, with pointed feathers, and add to the dove’s elegant and streamlined figure.
The elongated tail is an essential part of the Mourning Dove’s overall look, and it contrasts with the more angular tail of the White-winged Dove.
Wing Color
- White-winged Dove: One of the striking features of White-winged Doves is their distinct wing coloration.
These doves have white or light gray wing patches that become conspicuous during flight. These patches stand out against their gray-brown bodies and contribute to their visual appeal, especially when they are in motion. - Mourning Dove: Mourning doves possess gray-brown wings with a subtle pinkish hue on the underside. Unlike White-winged Doves, they lack the prominent white patches on their wings. This contributes to a more uniform appearance during flight, without the sharp contrast of wing markings that is characteristic of the White-winged Dove.
Body Color
- White-winged Dove: White-winged Doves have a generally consistent gray-brown body coloration, which complements their white wing patches. This coloration helps them blend into their arid and urban habitats while allowing their wing patches to stand out when they fly.
- Mourning Dove: Similar to White-winged Doves, Mourning Doves also exhibit a gray-brown body coloration. However, their plumage lacks the white wing patches. The pinkish hue on the underside of their wings adds a subtle touch of color to their appearance.
This consistent body color, devoid of striking wing patches, contributes to their more understated and subdued look.
Wing Sound
