Here's how to tell the difference

Yellow-Bellied Tit
Pardaliparus venustulus
General appearance
The Yellow-bellied Tit is a small bird species characterized by its striking coloration and distinctive features. It measures around 13 centimeters in length with a modestly-sized tail. It has a glossy black head, back, and tail while its underparts, cheeks, and a patch on its neck are a vibrant yellow. Its eye is also fringed by a thin, white line.
Male vs female
Notably, there are no drastic differences between the male and female Yellow-bellied Tit. They both share the same coloration and physical appearance, making it challenging to distinguish between them based on aesthetics alone. Apart from slight size variation, which is hardly noticeable, the males and females are visually almost identical.
Juvenile
Juvenile Yellow-bellied Tits are distinguishable from adults by their duller coloration. They display less vibrant yellow underparts and their black feathers lack the glossy sheen present in the adults. Moreover, juveniles possess a less distinct, greyish-white ring around their eyes. Over time, their colors develop, becoming more pronounced and glossy as they mature into adulthood.

Poecile montanus
General appearance
The Willow Tit (Poecile montanus) is a small, plump songbird with a robust body. Its plumage primarily consists of grey, brown, and white shades. The head is capped in glossy black extending to the nape, contrasting sharply with the pale cheeks. The upperparts are brownish-grey while the underparts are white, with sides tinged buff-brown. Its wings and tail boast a darker hue. An essential characteristic is a small black bib under its chin.
Male vs female
There is minimal sexual dimorphism in Willow Tits, making it hard to distinguish males from females by appearance. Both sexes have similar coloration and size. Thus, identification between genders is generally achieved through their distinct vocalizations.
Juvenile
Juvenile Willow Tits resemble the adults, but the glossy black cap is duller and they lack the black bib of mature birds. Additionally, juveniles exhibit a paler plumage with a more yellowish-brown hue. As they age, the coloration gradually darkens, approaching the adult appearance by their first winter.

Visual differences
The Yellow-Bellied Tit measures about 4.7 inches long and features striking black and vibrant yellow plumage, with a glossy black head and tail, and a thin white line around the eye. In contrast, the Willow Tit is slightly larger at 4.3-4.7 inches, exhibits duller plumage with grey, brown, and white tones, and has a distinct black cap extending to the nape and a small black bib under the chin. The Yellow-Bellied Tit's bright underparts sharply contrast with the Willow Tit's buff-brown and white underparts.
Key differences and behavior
The Yellow-Bellied Tit and Willow Tit differ notably in behavior and habitat preferences. Yellow-Bellied Tits, found in East Asian mixed forests, prefer foraging in small family groups and engage in complex courtship displays. Both parents share feeding duties, while only females incubate eggs. They nest in trees and occasionally urban gardens. In contrast, Willow Tits are found in wetter, cooler regions such as damp deciduous forests across Europe and Asia. Known for strong pair bonds formed in late winter, they excavate nests in decaying wood. Their diets are similar, both favoring insects and seeds, but Yellow-Bellied Tits often visit bird feeders for nuts, while Willow Tits prefer sunflower seeds. Both birds exhibit little sexual dimorphism, but over-wintering and nesting behaviors can be key differentiation points, alongside their distinct regional habitats.
