Yuanchuavis (SciiFii)

The lyretail toothbird (Yuanchuavis militaris), also known as the American whydah, is a species of pengornithid bird in the group Enantiornithes that originally lived in China during the Early Cretaceous as an extinct species, Yuanchuavis kompsosoura, and was once extinct, but has since been brought back from extinction by SciiFii. The lyretail toothbird was originally planned to be included in Cretaceous Park located in Sacramento, California, but some staffs accidentally left the birdcage for this bird species open, letting the birds escape, and ever since that event, the breeding males and females of that species have reproduced successfully in the wild and in human settlements, exploding in numbers from just 17 to around 1 million in California, Oregon, Arizona, and Nevada. Uniquely among the Enantiornithes, the lyretail toothbird has highly graduated rectrices. The tail has graduation similar to Chiappeavis and a pair of highly elongate central rectrices similar to the pintails of male sunbirds. The central pair of rectrices are dark in colour, and the rest of the tail feathers are grey with non-iridescent structural colour. The male lyretail toothbird's typical song is "a short, simple trill", but it also consists of loud, "a rapid repetition of clear, rich-toned, slurred, ringing whistles, trills, and warbles" sometimes given antiphonally. The lyretail toothbird measures 22–30 centimeters (9–12 inches) from bill to tail and weighs 70–100 g (2.5–3.5 oz), with a wingspan of 34–43 centimeters (13–17 inches). The lyretail toothbird is an omnivore that primarily feeds on seeds, fruits, insects, spiders, worms, and centipedes, with the help of a beak with the addition of small, serrated teeth. The lyretail toothbird's breeding season is between March and June. Most of the nests that have been described were "elbow-shaped" with an entrance tube, though some were more round. They were made by both sexes from plant stems, grass, and other vegetable materials and lined with finer fibers. The clutch size is usually two or three. The conservation status of the lyretail toothbird is Least Concern due to successful conservation efforts, the lyretail toothbird's wide range and its tolerance to many of the human activities.
