Bird Profile: The Nut Hatch

1. Nombre del ave
English Name: Nut Hatch
Scientific Name: Sittidae

2. Aspecto
The Nut Hatch is recognized for their short tail and a long, strong bill. Their blue-grey upper-parts and whitish underparts with rust-colored flanks set them apart, with feather patterns varying subtly across species. Some species’ have a distinct black stripe through their eyes, while others are outlined with white on their neck and around their eyes. Their beak is dark, thick, and pointed upwards and their eyes are dark and intense.

Unlike many bird species, Nut Hatches do not exhibit sexual dimorphism, meaning males and females look very similar. However, during breeding season, males’ colors may become slightly more vivid.

3. Tamaño
The average Nut Hatch sizes between 10–22 cm (4–9 inches) in length with a wingspan reaching between 20-30 cm (8-12 inches). They weigh anywhere between 10–25 grams (0.35–0.88 oz).

4. Hábitat y distribución
Nut Hatches are found mainly in the northern hemisphere, spread across North America, Europe, Asia, and Northern parts of Africa. They inhabit old forests, gardens, parklands, and wooded areas where they perform important pest control functions. Strikingly adaptable, Nut Hatches can tolerate a variety of climates.

5. Datos de interés
One unique behavior of the Nut Hatcher is its ability to walk head-first down tree trunks. Additionally, Nut Hatches are also known to store food for the winter in crevices under the tree bark. Interestingly, these birds possess innate cognitive abilities that enable them to remember hundreds of such storage locations.

6. Dieta
Nut Hatches have an omnivorous diet feeding primarily on insects, seeds, nuts, and other plant matter. They use their strong bills to break open nuts and seeds left in the crevices of tree bark.

7. Comportamiento y sonidos
Nesting in tree holes often lined with bark strips, wood chips, or fur, Nut Hatches usually lay 6-10 eggs. Their flight pattern is swift and straight with rapid wing beats. Their calls are an assortment of short and loud notes often repeated in series, creating a song-like chorus.

8. Estado de conservación
Most of the Nut Hatch species are listed as “least concern” on the IUCN Red list, with varied levels of local population fluctuations due to habitat loss and fragmentation.

9. Vida útil
Nut Hatches live for an average span of 2–12 years in the wild, although this can sometimes extend up to 20 years under optimal conditions in captivity.

10. Notas adicionales
In Turkish, the Nut Hatch is called “Anadolu Sıvacısı”. They are known for forming mutualistic relationships with Picidae birds, often using their deserted tree cavities for nesting. Their unique ‘plastering’ behavior helps control the hole’s size and also works as a deterrent for predators and parasites. This crucial role in the ecosystem enhances forest health, contributing to insect population control. Despite their small size, Nut Hatches are exceptionally robust, defending their territories resolutely against invaders. Another interesting aspect is their friendliness toward humans, frequently visiting bird feeders in gardens and becoming fairly tame.
