Well, perhaps it is just an upswing in hormones as spring approaches and they are singing everything in their repertoire and for them they aren’t copying another bird, they are just full of song of every type they have mastered. Perhaps. How long is the average life span of a Euro Starling? My ancient Teres encyclopedia cites references of Starlings living 9 to 20 years. Plenty of spring seasons to practice every song.
