The Black-and-gold Tanager sings regularly and conspicuously from treetops during March and April, often for prolonged periods during sunset (Stiles 1998, Sedano 2014). The song is composed of 3-5 rapidly delivered pit-psEEyee pit-pit-psEEyee or tst-tzEEeee phrases (Stiles 1998). These phrases are followed by a pause of several seconds before the next group of phrases (Stiles 1998). The tst sound is staccato, the tzEEeee bursts high-pitched and penetrating. The song length is about 1.2 seconds with a frequency between 5138-9335 Hz (Mason 2012). The contact call is a sharp tst or pit, with lone birds occasionally giving a longer and wavering keerlu, pseee or pseeyee (Pearman 1993, Stiles 1998). When in mixed-species flocks it will give an emphatic pit pit pit and spit spit (Hilty 2011). An individual was observed delivering rapid sharp tsip notes high and exposed on a treetop before diving into cover just before a Semicollared Hawk (Accipiter collaris) took the tanager's perch (Stiles 1998). The begging call is a continuous phrases very high pitched, squeaky. Additional audio recordings of vocalization of the Black-and-Gold Tanager can be heard at Macaulay Library, the Internet Bird Collection, and at xeno-canto.
