Taxonomy
Subspecies
There are 3 subspecies[1]:
- S. m. parva:

- S. m. minuta:
Habitat
They like open spaces and are often seen beside roads, in parks and close to houses.
Behaviour

Vocalisations
Song is simple but plaintive and sweet, see-seeur tee-te-e-e-e, seeeeeur tse-e-e-e. Call variable sharp chip or chunk.
Movements
Mostly sedentary, but may disperse when food is scarce because of drought.
