The impact that wiped out the dinosaurs also wiped out all songbirds, except for in (ark) Australia. Australian songbirds then spread out to rest of the planet.
The closest living descendents (aka basal lineages) are the Lyrebird and the Rufus scrub bird. The lyrebird’s song is a mixture of its own song and other birds songs. They have been also been known to mimic chainsaws, car alarms, camera shutters, and human speech.
You should know! I consider it important information that is necessary for life, as now you get to imagine every songbird tossing in a “cunt” or “good on ya” while twittering away.
My thought is that it also implies that there’s a good chance dinosaurs sang.
