As a rule, this Grebe is a silent bird rather than otherwise ; its call-note, which is usually 

 heard at its breeding-place, or when they collect together before migrating, is a soft, clear 

 whistling sound, resembling the syllables bib bib ; and during the pairing-season it utters a clear 

 and very distinct cry, like the syllables bide wide wide wide wide quickly emitted. This note or 

 love-song is usually heard in the evening or during the fine summer nights. 



The specimens figured are an adult male in full breeding-dress and an old bird in winter.
