Trees for Life - Species Profile: Crested tit |
 | | The crested tit can live for up to seven years, but the average lifespan is much shorter, at two years, due to factors such as predation, starvation in winter etc. Vocalisations consist of a soft, purring trill, which is repeated as a song, and high-pitched 'zee-zee-zee' calls. |
 | | The crested tit is a resident, non-migratory species, and is sedentary - it generally remains in the area where it was born. |
 | | Because of their use of snags for nesting, the presence of the crested tit is an indicator of the ecological health of a forest, which should naturally contain standing dead trees. |
