If I have incorrectly identified this tree please let me know.
Rowan adds colour to woodland throughout Ireland, especially in the hills where it will grow at a high altitude even on rocky ground: its other common name is mountain ash.
The creamy flowers ripen into scarlet berries which colour early in the season and provide food for thrushes through the winter. A mistle thrush will defend a rowan tree or holly as its territory, not for nesting, but through the winter as its feeding territory.
