Treecreepers favour coniferous woodland, they get their name from the way in which they feed.

An insect-eater, the Treecreeper also eats spiders, and in wintertime some seeds.
It has a long, downward-curving bill, perfect for the task of picking them out of the crevices in bark.

Starting at the base of a tree and quietly creeping upward in a jerky manner, a Treecreeper moves up the trunk following a spiralling a path upward then moves along the thicker branches searching for insects. It then flies down and starts the process again on another tree. A treecreeper has distinctive long toes which help it to grip the bark of a tree.

 

Treecreepers were 55% below usual productivity in 2007. This is their worst year on record.

In the Western Isles there was a peak of about 10 pairs in Stornoway Castle Grounds in 1966, since then they have declined in number, with only one or two sightings some years.

There are only about three records of Treecreepers anywhere in the Western Isles outside of the Stornoway Castle Grounds. One of them made a number of years ago, was a report of a Treecreeper feeding on Mingulay cliffs.


Additionally in October 2006 one was spotted in a garden in Gisla, on the Isle of Lewis.
