- Observations
While age at sexual maturity is unknown, it may take several years for young to begin breeding [0440].
Both males and females have been shown to have a decline of competitive behaviour with age, demonstrated by their increased vulnerability towards territory eviction (by both aged males and females) and low resettlement rates (by only the males) [1344].
