Marico Sunbird vs Red-chested Sunbird

In short

The Marico Sunbird and Red-chested Sunbird are both small, colorful sunbirds with overlapping ranges in parts of Africa. The most reliable field mark is the plumage coloration: the Marico Sunbird has a metallic green head and upperparts, while the Red-chested Sunbird features a distinctive red chest. Both species have similar structures, but differences in plumage and habitat preferences can aid in identification.

Identification tips

1. Look for the metallic green head and purple throat of the Marico Sunbird versus the red chest of the Red-chested Sunbird. 2. Consider habitat: Marico Sunbirds are more likely in open woodlands, while Red-chested Sunbirds prefer forest edges. 3. Note the female plumage differences: Marico females are more uniformly olive-brown. 4. Listen for subtle differences in song with experience.
