Little thornbirds are skilled stick architects, building bulky, spiny nests with side entrances that they add to and reuse across seasons. These nests are often placed in thorny shrubs or small trees and may be used by other species after abandonment. The species forages quietly but becomes conspicuous when pairs deliver ringing duet songs.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats, low undulating hops between shrubs
Social Behavior
Typically found in territorial pairs that maintain and defend nesting sites year-round. Both sexes build the large stick nest, often in thorny bushes or small trees, and may repair or enlarge it between breeding attempts. Monogamous pairs coordinate foraging and stay in close contact with calls.
Migratory Pattern
Resident
Song Description
Pairs deliver clear, ringing whistles that accelerate into chatter, often given as coordinated duets. Calls include sharp chips and scolds when alarmed, and softer contact notes while foraging.
