Eastern Rock Nuthatch vs Krüper's Nuthatch

Eastern Rock Nuthatch

Sitta tephronota

Small35 gRocky

Eastern rock nuthatch is 15–16 cm long. It is one of the least brightly coloured nuthatches, with pale blue-grey upperparts, a white breast, and the belly grading from white to pale orange-buff on the under-tail coverts. The head has a bold black eyestripe. The subspecies range in size from smaller in the east, to largest in the west; S. t. iranica and S. t. tephronota are the smallest, at 30–39 g, while S. t. dresseri at 42.7–55 g is the largest. This last subspecies, while not as long-bodied as the giant nuthatch, is the heaviest in the entire family.

Krüper's Nuthatch

Sitta krueperi

Tiny12 gForest

The Krüper's nuthatch is a small to medium-sized nuthatch, measuring 12.5 centimetres (4.9 in) in length. In males and females, the folded wing measures 71–81 millimetres (2.8–3.2 in) and 68–74 millimetres (2.7–2.9 in) respectively, the tail 33–40 millimetres (1.3–1.6 in) and 33–38 millimetres (1.3–1.5 in). The bill measures 17.9–20.2 millimetres (0.70–0.80 in) and the tarsus 16.9–19.3 millimetres (0.67–0.76 in). The adult male weighs 10–14.3 grams (0.35–0.50 oz). Voice: The Krüper's nuthatch is a noisy bird, and is often easily detected and identified by its calls. The contact call is a dvui, sometimes made in a dui-dui-dui-dui series and reminiscent of the European greenfinch (Chloris chloris). When agitated, it produces a rough èèhch reminiscent of the Eurasian jay (Garrulus glandarius) or a dry puik.
