The songbirds are birds appearing in "Pups Save the Songbirds".
In "Pups Save the Songbirds", the adult songbirds of Adventure Bay go missing as part of Mayor Humdinger's scheme. This leaves the baby songbirds without caretakers. The PAW Patrol has to stop Humdinger and help find the birds.
The adult songbirds have orange, white, and purple feathers and purple eyes. The baby songbirds have larger heads, no orange feathers, and ice-blue eyes.
