Oriental Magpie or Yellow-Billed Magpie?
Here's how to tell the difference
Oriental Magpie
Yellow-Billed Magpie
Oriental Magpie
Pica serica
Also known as: Korean Magpie, Asian Magpie
General appearance
The Oriental magpie, also known as the Oriental magpie-robin, is a small passerine bird native to East Asia. These birds sport distinctive black and white coloration. The upperparts are glossy black with a thick white wing bar, while the underparts are pure white. They have a long, black tail with white corners. Their black bill and legs, along with reddish eyes, add to their striking appearance.
Male vs female
Male and female Oriental magpies exhibit minor sexual dichromatism. Males are largely black above with a white wing patch, while the underparts, rump, and sides of the long tail are white. Females, on the other hand, are greyish-brown where the males are black. Moreover, females have less white in the tail.
Juvenile
Juvenile Oriental magpies resemble females but are even duller, with a hint of rufous on the underparts. They lack the defined feather borders and the fulness of hue of both male and female adults. As they mature, their colors will become more vibrant and differentiated.

General appearance
The Yellow-billed Magpie, standing between 16-18 inches (41-46 cm), is about the size of a Crow or Mallard. Colors are predominantly black, blue, green, white, and yellow. Most striking is the bright yellow bill and yellow skin near the eyes. It has a long, wedge-shaped tail, round and broad wings with finger-like extensions.
Male vs female
Both male and female yellow-billed magpies are similar in appearance, with no significant differences in size or coloration to easily distinguish them. Both sexes possess the distinctive yellow bill and surrounding yellow eye skin.
Juvenile
Juvenile Yellow-billed Magpies initially have less vibrant coloration than adults. Beak color gradually changes from initially dark to the characteristic bright yellow as the bird matures. They achieve their adult size and pigmentation at an early age.

Visual differences
The Oriental Magpie (Pica serica) and Yellow-Billed Magpie (Pica nuttalli) differ visually primarily in beak color and facial markings. Oriental Magpies have a black bill and overall black-and-white plumage, with reddish eyes. They are 18-20 inches long. Yellow-Billed Magpies are slightly smaller at 16-18 inches, with a striking bright yellow bill and yellow eye skin, sporting black, blue, green, and white colors. Both have long tails, but the Yellow-Billed Magpie's wedge-shaped tail is notable, blending into its lively blue and green iridescent feathers.
Key differences and behavior
Oriental Magpies (Pica serica) and Yellow-Billed Magpies (Pica nuttalli) display distinct behaviors and preferences. Oriental Magpies, native to East Asia, show adaptability to urban environments, thriving in forests, parks, and gardens. They perform vocal courtship displays and construct cup-shaped nests in trees, with both parents caring for the chicks. Their opportunistic diet includes insects, small mammals, fruits, and seeds. In contrast, the Yellow-Billed Magpies, residing in Californian oak savannas and ranches, are more sociable, forming flocks and long-term monogamous pairs. They prefer open landscapes and build large, dome-shaped nests often in colonies. Their diet is similar but includes a higher focus on insects and grains. Yellow-billed magpies engage in elaborate courtship involving aerial displays and vocalizations. Both species are omnivorous and opportunistic at feeders, but their habitat preferences and nesting structures are key distinguishing factors.
