Bradycneme draculae
Bradycneme (meaning "ponderous leg") is a genus of theropod dinosaur from the Upper Cretaceous-aged (Maastrichtian) Sânpetru Formation of the Hațeg Basin, Transylvania, Romania. The type species is Bradycneme draculae, known only from a partial right lower leg (specimen BMNH A1588), which its original describers believed it came from a giant owl.

Heptasteornis
Heptasteornis is a dubious genus of alvarezsaurid dinosaur from the Late Cretaceous. The type (and only known) species is Heptasteornis andrewsi, described as a presumed gigantic prehistoric owl in 1975. It was previously included in Elopteryx nopcsai and indeed the holotypes of both species were believed to be from the same individual as they were discovered, and initially were assigned the same specimen number. This appears to be in error however (see below).
Wyleyia
Wyleyia is an extinct genus of indeterminate maniraptoran dinosaurs containing a single species, Wyleyia valdensis, known from the early Cretaceous period of Sussex, England. The genus is known from a single specimen, a damaged right humerus. It was named to honor J. F. Wyley, who found the specimen in Weald Clay deposits of Henfield in Sussex (England). The specific name valdensis means "from the Weald".
