What do white-breasted nuthatches like to eat?

Natural diet

The white-breasted nuthatch primarily consumes insects and spiders during the summer. In winter, its diet shifts to include a significant proportion of seeds, which can make up more than 60% of its diet during this season. The young are fed entirely on insects and spiders.

Bird feeders

At bird feeders, the white-breasted nuthatch will also consume suet and peanut-butter mixtures, supplementing its natural diet with these readily available food sources.

What does a white-breasted nuthatch sound like?

The white-breasted nuthatch communicates through various vocalizations. Its typical call includes a nasal 'yank-yank' and a distinctive call pattern starting with a flat note followed by a rising pitch. Furthermore, it showcases a range of call types including chirp/chip, raucous, and scream. Its song comprises a series of low-whistled notes, contributing to its unique bird song repertoire.

Pygmy Nuthatch

Sitta pygmaea

How to recognise a pygmy nuthatch?

General appearance

The pygmy nuthatch is a small, compact bird measuring around 4 inches in length. It features a grayish-blue upper body and a buffy-white underbelly. The most distinctive feature is its cap, which is a contrasting dark gray. Its sharp, pointed beak and short tail add to its characteristic structure. The bird often appears agile, clinging to tree trunks and branches.

Male vs female

There is little to no sexual dimorphism in pygmy nuthatches, making it difficult to distinguish between males and females based solely on appearance. Both sexes share the same plumage coloration and pattern across all seasons.

Juvenile

Juvenile pygmy nuthatches are similar in appearance to adults but may appear slightly duller in coloration. Their underparts can be more muted, with a softer contrast between the gray cap and the rest of the plumage. As they mature, their colors become more distinct, matching those of adult birds.

Size

3.5 - 4.3 in/0.3 - 0.4 oz

Habitat

Primary habitat

The Pygmy Nuthatch's preferred habitat is the Yellow Pine region throughout the mountains of the west, including Ponderosa and Jeffrey pines.

Additional range

Additional habitats encompass Monterey Pine in California coast, Pinyon-Juniper woodland, and Redwood Canyons. Occasionally, they can visit the lowlands, often seen in planted conifers.

Range Map

What do pygmy nuthatches like to eat?

Natural diet

The pygmy nuthatch's natural diet consists mainly of insects and seeds. During summer, it primarily consumes insects like beetles, wasps, caterpillars, and true bugs. In winter, its diet shifts to include a high intake of seeds, particularly pine seeds. Nestlings are mostly fed insects, highlighting the importance of insect consumption in their early development.

Bird feeders

Pygmy nuthatches visiting bird feeders may consume sunflower seeds, suet, and small pieces of nuts. They are particularly attracted to feeders offering seeds similar to those found in their natural habitat, such as pine seeds, and are also drawn to protein-rich offerings that mimic their insect diet.

What does a pygmy nuthatch sound like?

The Pygmy Nuthatch produces a monotonous, repetitive "peep, peep-peep" sound. The pattern of its vocalizations generally falls or is flat, displaying a lack of variation in pitch or rhythm. This bird's usual call type is categorized as a chirp or chip, indicative of short, sharp sounds frequently used for communication. Its simplistic and repetitive peeping makes its call distinct and easily recognizable.

How to tell the White-Breasted Nuthatch from the Pygmy Nuthatch

Visual differences

The White-Breasted Nuthatch is larger, measuring 5-6 inches, with a distinctive white face and chest, and a narrow black crown stripe in males. It has a chunky body and a thin bill. In contrast, the smaller Pygmy Nuthatch is about 4 inches long, with a grayish-blue upper body and buffy-white underbelly. Its cap is a dark gray. The Pygmy Nuthatch has a sharp, pointed beak and a more compact form. Both species have a short tail, but the White-Breasted Nuthatch appears more robust.

Key differences and behavior

The White-Breasted Nuthatch and Pygmy Nuthatch can be distinguished behaviorally and ecologically. The White-Breasted Nuthatch, around 5-6 inches long, frequents mature deciduous forests and suburban areas, often seen walking headfirst down tree trunks searching for insects. Monogamous, they nest in tree cavities, with males actively participating in pair bonding. During summer, they eat insects, shifting to seeds, suet, and peanut-butter mixtures at feeders in winter. In contrast, the Pygmy Nuthatch, at about 4 inches, inhabits pine-rich forests. They engage in cooperative breeding, with 'helpers' assisting the primary pair. These birds gather in large groups for warmth and energy conservation. Their diet predominantly consists of insects and pine seeds, especially in winter, and they are drawn to feeders offering sunflower seeds and nuts. While the White-Breasted Nuthatch is more of a solitary suburban visitor, the Pygmy thrives in communal mountain ecosystems.
