Rothschild's lobe billed bird of paradise

Rothschild's lobe-billed bird of paradise ("Loborhamphus nobilis"), also known as the noble lobe-bill, is one of six enigmatic species of bird-of-paradise collected in Papua New Guinea for zoologist Lionel Walter Rothschild. It is only known from the holotype.

In 1930 it, along with the five other collected species, was considered by Erwin Stresemann to be a hybrid, presumptively between the long-tailed paradigalla and the superb bird of paradise, though doubts have been raised about the parentage.
