Excuse me TJ - & belated thanks also! I tend to skip over your posts as they are often quite wordy.
Ever since Helena gave me 'raven', I've been wondering why the answer to "Porkie on the wing?" was 'lyrevird' (other than it fits the required 8 letters, of course).
In the meantime, just for diversion, I recently saw this cryptic clue somewhere: 1a.Arizonan Bird? W?O????.
