Eurasian Scops-Owl
Otus scops
Very small owl with golden-yellow eyes. Cryptic and well-camouflaged, with streaky gray-brown plumage that blends in perfectly with tree bark. Small ear tufts raised when alert. Much more easily detected at night, when monotonously repeated and well-carrying song, a single plaintive hoot, is given. Found in a variety of open woodlands, scrubby areas, orchards, and parks.
Identification
The Eurasian scops owl is 19–21 cm (7.5–8.3 in) in length with a wingspan of 47–54 cm (19–21 in). This is somewhat smaller than the little owl (Athene noctua). It perches upright and shows small ear-tufts. The plumage is predominantly grey-brown in colour, with a paler face, underparts and shoulder line. This species has a strong direct flight on long narrow wings, reflecting its migratory habits.<p>The call is a deep whistle given by both sexes. It is similar to the call of midwife toads in the genus Alytes.
Taxonomy
The Eurasian scops owl was formally described by Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae. Linnaeus cited the 1599 description by the Italian naturalist Ulisse Aldrovandi, placed it with all the other owls in the genus Strix and coined the binomial name Strix scops. The Eurasian scops owl is now placed in the genus Otus that was introduced in 1769 by Welsh naturalist Thomas Pennant. The genus name is derived from the Latin otus meaning "eared owl". The specific epithet scops is from the Ancient Greek word skōps for a little eared owl. The term is believed to be of Pre-Greek origin; folk etymology links it to σκώπτω (skṓptō, "to mock") or σκέπτομαι (sképtomai, "to examine").<p>Five subspecies are recognised:

Range and habitat
This bird breeds in southern Europe eastwards into western and central Asia. It is migratory, wintering in southernmost Europe and sub-Saharan Africa. It was spotted in Newtown area near Kolkata for a brief period during October 2021. It was the first sighting in eastern India. It is rare any distance north of its breeding range, usually occurring as a spring overshoot. It is unlikely that this nocturnal owl would be found outside the breeding season when it is not calling.

Behavior
Eurasian scops owls breed in open woodland, parks and gardens. The nest is usually a hole in a tree or in a wall, but can sometimes be an old nest of another species such as a crow. The clutch is usually 4 or 5 eggs. These are white and measure 31 mm × 27 mm (1.2 in × 1.1 in) and weigh around 13 g (0.46 oz). The eggs are incubated only by the female. They hatch after 24-25 days. The young are cared for and fed by both parents. They fledge when aged 21–29 days and become independent of their parents at 30–40 days of age.<p>It takes small prey such as insects and other invertebrates. It is largely nocturnal.

Marcapata Spinetail

Fairly small, long-tailed bird found in a small range in the Peruvian Andes. Reddish brown above, pale tan below, with a pale eyebrow edged in black and a variably colored crown. In the eastern part of its range, the crown is reddish brown; in its northwestern populations, the crown is creamy white. Has a bolder whitish throat and eyebrow than the similar Ash-browed Spinetail, which is typically found at lower elevations. Marcapata Spinetail forages in low vegetation in cloud forest, especially in thick bamboo. Listen for its song, a descending series of staccato, metallic notes.
