The entry holes are usually oblong and six to nine inches (152–228 mm) [3] that permits a single bird to enter with space for a safe landing and passage to the interior whilst at the same time excluding larger predators. [1] Owl holes without landing platforms had grooves or rough surfaces beneath the hole to aid grip.
The eastern rock nuthatch builds a similar but less complex structure across the entrance to a cavity. Its nest can be quite small but may weigh up to 32 kg (70 lb). This species will also nest in river banks or tree holes and will enlarge its nest hole if it the cavity is too small. [45]
Deep cup nest of the great reed-warbler. A bird nest is the spot in which a bird lays and incubates its eggs and raises its young.

The nest is an underground horizontal oval chamber lined with shredded bark, linked by a tunnel 0.5 to 1.5 metres (1 ft 8 in to 4 ft 11 in) long to a hole in the side of a riverbank or slope in a shaded location.

The female usually lays 4–5 eggs speckled with brown or gray.
Both sexes help with the nest excavation. The entrance hole is about 8 cm (3 in) in diameter, and the cavity is 33–41 cm (13–16 in) deep. The cavity widens at the bottom to make room for the eggs and the incubating adult. Inside, the cavity is bare except for a bed of wood chips for the eggs and chicks to rest on. [23]
