The Eurasian tree creeper.
Tree creepers are small birds with streaked and spotted brown upper parts,
rufous rumps and whitish underparts. They have long decurved bills,
and long rigid tail feathers that provide support as they creep up tree trunks
looking for insects. The Eurasian tree creeper is
12.5 cm (4.9 in) long and weighs 7.0–12.9 g (0.25–0.46 oz).
