In birds with song repertoires, individuals may share the same song type and use these song types for more complex communication. [23] Some birds will respond to a shared song type with a song-type match (i.e. with the same song type). [24] This may be an aggressive signal; however, results are mixed. [23]
Second broods are common, with the female reusing the same nest if the brood was successful, and three broods may be raised in the south of the common blackbird's range. [8] A common blackbird has an average life expectancy of 2.4 years, [35] and, based on data from bird ringing, the oldest recorded age is 21 years and 10 months. [36]

This bird's song resembles the grating of a rusty hinge. Male yellow-headed blackbirds have been observed to have two types of songs, an "accent song" and a "buzz song". The “buzz songs'' have much higher pitch than the accent song, and thus do not echo as well in the dense marshes they live in.
The rusty blackbird (Euphagus carolinus) is a medium-sized New World blackbird, closely related to grackles ("rusty grackle" is an older name for the species). It is a bird that prefers wet forested areas, breeding in the boreal forest and muskeg across northern Canada , and migrating southeast to the United States during winter.
