On average, these beautiful birds are about 6.3 inches (16 cm) in length but males can easily reach a length of 8.25 inches (21 cm) when including their curlicue tail feathers. Wilson's bird of paradise has a 5-8 year lifespan in the wild, but it can survive up to 30 years in captivity.
One of the birds’ most famous features is their mating habits. Since the male Wilson's Bird of Paradise engages in polygamy, this species does not have a lifelong partner. A male can pair up with several females at a time. After eggs are born, females often construct and maintain nests for their kids. And while females are protecting their nests, males simply leave and search for new mates to work hard with! How disloyal these birds are!!!
