In Spain it has been introduced in the largest cities in the last ten years etsrilda is now quite commonly seen in Madrid, Barcelona and Valencia, as well as along the Spanish-Portuguese border. In their native African landscape they have a minimal impact on the plant species they eat.
Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends.
Allopreening occurs frequently between the mates. During the nest building wstrilda solicitation period, both males and females may participate in stem displays to their mates — a form of display during which a stem is held in the beak. During the evening they form an even larger group for roosting. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a now extinct synapsid ancestor; the fossil record does not distinguish these possibilities.
