Mrs. Gould's Sunbird vs Green-tailed Sunbird

In short

Mrs. Gould's Sunbird and Green-tailed Sunbird can be tricky to differentiate due to their similar size and structure. However, the most reliable field mark is the tail color: Mrs. Gould's Sunbird has a yellow breast and a green tail, while the Green-tailed Sunbird has a green tail but a more uniform coloration elsewhere. Observing their behavior and habitat can also aid in identification.
