Long-tailed Widowbird
Euplectes progne
Long-tailed widowbirds exhibit distinct sexual dimorphism. Males and females exhibit differences in behaviour and morphological traits. Adult males are entirely black, including under their wing-coverts. Males' wing shoulders are orange red and their wing-coverts white. Their bills are bluish white. Males are known for their distinctly long tails, which contain twelve tail feathers. Of these twelve tail feathers, between six and eight are approximately half a metre (approximately 20 inches) long. Males have wingspans of approximately 127 to 147 mm (approximately 5 to 5.8 inches).

Red-collared Widowbird
Euplectes ardens
Similar to other widowbirds, male red-collared widowbirds have both seasonal and sexual dimorphism. Males are about 25 cm (9.8 in) in length while females are only 13 centimeters. A similar trend is seen with weight, where males range from 20 to 26 g (0.71 to 0.92 oz) and females are only between 16 and 22 grams. During non-breeding seasons, the male plumage is brown, while in breeding season, October to April, they have black plumage with a long tail, approximately 22 cm, and crescent-shaped carotenoid based chest patch.
