This species has several different calls.
One call of the Yucatan Jay is a simple harsh clatter or rattle which has been described as similar to that of the Great-tailed Grackle (Quiscalus mexicanus).
The jay also makes a sharp "pip" which is followed by a series of high-pitched clear notes resembling a titmouse. The song was described by Davis in 1957 as "Chea-chea-chea-chea-chea" lasting about one second with the "chea" pitched the fourth G above middle C. The call is very fast, so the slurring of the end of the song down by about one tone is not easily noticed. The call resembles that of the Peten Vireo (Vireo semiflavus), but the vireo usually repeats its call while the jay usually sings only once. The call is also similar to that of the Orange Oriole (Icterus auratus) but lacks the preliminary phrase which the oriole places ahead of its "che" notes.
The "chea" song is sometimes preceded by a loud nasal "eyah" which last for 1/4 to 1/3 of a second and is an octave lower than the "chea" series (Davis 1957)
