Indian Yellow Tit

About

The Indian Yellow Tit (Machlolophus aplonotus) is a small, striking passerine bird belonging to the tit family Paridae. It is characterized by its bright yellow underparts, black crest, and distinctive facial pattern. Formerly considered a subspecies of the Black-lored Tit (Machlolophus xanthogenys), it was elevated to full species status based on genetic and morphological differences. It is an active, arboreal insectivore found in various woodland habitats across the Indian subcontinent.

Size & lifespan

Length

13-14 cm

Wingspan

20-22 cm

Weight

10-15 g

Lifespan

3-5 years in the wild (estimated)

Diet

Insectivore (primarily insects and their larvae, spiders, occasionally seeds and berries)

Physical characteristics

Plumage

Adults have bright yellow underparts, a prominent black crest, and a black throat and breast band that extends down the belly as a broad central stripe. The upperparts are olive-green to greyish-green. The wings are dark with two distinct white wing-bars. The tail is dark with white outer tail feathers. A distinctive black eye-stripe runs through the eye, contrasting with yellow cheeks and a yellow supercilium.

Beak shape

Small, conical, sharp, and black.

Eye color

Dark brown.

Leg color

Dark grey to blackish.

Distinguishing features

The prominent black crest, bright yellow underparts with a broad black central stripe, and two white wing-bars are key identification features. The facial pattern of black eye-stripe, yellow cheeks, and yellow supercilium is also diagnostic.

Juvenile appearance

Juveniles are duller overall, with less vibrant yellow underparts, a less distinct black central stripe, and a shorter, less prominent crest. The upperparts may be browner, and the facial markings less sharply defined.

Seasonal changes

No significant seasonal plumage changes are observed. Plumage remains consistent throughout the year, though wear and tear might make it appear slightly duller before molting.

Sexual dimorphism

Males and females are generally similar in plumage, though males may have slightly more intense coloration and a broader, more prominent black central stripe on the underparts. The crest might also be slightly larger in males.

How to identify

1. 1

   Crest

   Look for the prominent, erect black crest on the head, a key feature distinguishing it from many other small passerines.

2. 2

   Underparts Coloration

   Observe the bright yellow underparts with a broad, distinct black stripe running down the center of the breast and belly.

3. 3

   Facial Pattern

   Note the black eye-stripe contrasting with bright yellow cheeks and a yellow supercilium (eyebrow).

4. 4

   Wing-bars

   Identify the two clear white wing-bars on the dark wings, which are visible even in flight.

5. 5

   Upperparts

   The upperparts are typically olive-green to greyish-green, providing a contrast to the bright underparts.

6. 6

   Vocalization

   Listen for its distinctive, ringing 'chee-wee, chee-wee' song or sharp 'chick-a-dee' calls, which are often the first indication of its presence.

Habitat & range

Biomes

Tropical and subtropical dry broadleaf forests, moist lowland forests, montane forests, open woodlands, scrublands, orchards, and gardens.

Geographic range

Indian subcontinent, primarily peninsular India. Its range extends from Gujarat and Rajasthan eastwards through central India to West Bengal, and southwards throughout peninsular India.

Elevation range

Typically found from plains up to approximately 1,800 meters (6,000 feet) in hilly regions.

Preferred environments

Prefers deciduous and mixed deciduous forests, especially those with mature trees. Also common in well-wooded gardens, plantations, and groves near human habitation.

Behavior

Activity time

Diurnal, most active during the morning and late afternoon.

Feeding habits

Primarily insectivorous, foraging actively among foliage and bark for insects, caterpillars, spiders, and other small invertebrates. It gleans insects from leaves and twigs, often hanging upside down to access prey. Occasionally consumes small seeds, nectar, and berries. It is a very active feeder, constantly moving and exploring.

Social behavior

Usually seen in pairs or small family parties. Outside the breeding season, they often join mixed-species foraging flocks, particularly with other tits, warblers, and babblers.

Flight pattern

Undulating flight pattern, typical of tits, with rapid wing beats interspersed with short glides. Agile and acrobatic when foraging.

Migration pattern

Resident throughout its range; generally non-migratory. May undertake local movements in response to food availability or weather conditions.

Territoriality

Pairs defend a breeding territory during the nesting season, using vocalizations and displays to deter rivals.

Breeding & reproduction

Breeding season

Typically from March to June, varying slightly with geographical location and monsoon patterns.

Nesting habits

Nests are built in tree cavities, old woodpecker holes, or crevices in walls and rocks. The nest is a cup-shaped structure made of moss, grass, hair, feathers, and spider silk, often lined with softer materials.

Clutch size

Usually 4-6 eggs, but can range from 3 to 7.

Egg description

Eggs are white or creamy white, sparsely speckled or spotted with reddish-brown or purplish-grey, particularly at the broader end. They are oval-shaped.

Incubation period

Approximately 12-14 days, primarily by the female.

Fledging period

Chicks fledge about 16-18 days after hatching.

Parental care

Both parents participate in feeding the nestlings and fledglings. The female primarily incubates, while the male brings food to the female and later to the young.

Where to find

Field tips

1. Listen for calls. Their distinctive calls and songs are often easier to detect than spotting the bird itself, as they can be quite active and blend into foliage.
2. Observe mixed-species flocks. Outside the breeding season, they frequently join mixed-species foraging flocks, so look for them among other small birds.
3. Check tree canopies. They are arboreal and spend most of their time foraging in the canopy and mid-story of trees. Look for active movements among leaves and branches.
4. Patience and binoculars. Being small and active, they require patience and good binoculars for clear observation.

Fun facts

• The Indian Yellow Tit was only recently recognized as a full species, having been split from the Black-lored Tit (Machlolophus xanthogenys) based on genetic and morphological evidence.
• Like many tits, it is an acrobatic forager, often hanging upside down to inspect the undersides of leaves and branches for insects.
• Its diet of insects makes it a beneficial bird for controlling pest populations in agricultural and garden settings.
• The genus name 'Machlolophus' is derived from Greek, meaning 'large crest', referring to the prominent crest characteristic of these tits.
