"Fågel blå" "Blue Bird"

In the park opposite the City Hall, Tyra Lundgren has sculpted an excited baby bird that persistently screams for food. Or is it the blue bird of the fairy tale that those seeking help call on their beloved to regain their princely form?
Lundgren, Tyra, 1975, Kungsholmen, Bronze.
