Verdins (Auriparus flaviceps) grow up to 4.5 inches in length and have tiny bodies with medium-sized tails.

They are gray and have bright yellow heads and pointed beaks, which makes it easy to spot these birds.

They are insectivorous and feed on different insects on trees. Along with insects, these birds also consume the soft mast of trees.

Verdins are monogamous and stay with their partners throughout the breeding season. Once the breeding season winds up, the verdins go their own way.

Both males and females contribute to building the nest and raising the hatchlings.
