A tree creeper (Certhia familiaris) 5 inches (125mm) is a small bird with nicely marked plumage. It's back is brown and white and it's underside is plain white. It has long claws which it uses to climb up the trunks of trees to find insects which it feeds on and it's tail feathers are strengthened to help it cling to the bark. It's long curved bill is used to probe under the bark in search of food. Tree creepers are easily distinguished from other birds because of their method of searching for food. They will fly to the base of a tree and climb up it searching in every crevice for insects and grubs which are it's main food source. When it reaches the top it flies to the base of another tree and climbs that tree, repeating the process. Although insects are the main food they are quite happy to take fat or a mixture of fat and nuts from my tree trunk feeder as you can see from the pictures.
It makes it's nest of twiggs, grass, moss, bark, hair and feathers in any small crevice or behind the bark on a tree. Five to nine eggs are laid which are white spotted with reddy brown .
