Size

7.1 - 7.5 in/1.4 - 1.8 oz

Habitat

Primary habitat

The Black-headed Grosbeak primarily breeds in oak woodland, streamside cottonwood and willow groves, pine-oak woods, and pinyon-juniper woodland. It seldom occupies purely coniferous forests.

Additional range

During migration, it can be found in open woods, streamside trees, suburbs, mesquite groves, desert washes. It winters in the open woods and brush of the tropics, ranging from lowlands to mountains.

What do black-headed grosbeaks like to eat?

Natural diet

The black-headed grosbeak primarily feeds on a variety of insects, seeds, and berries. During the summer, it consumes numerous insects such as beetles, caterpillars, wasps, bees, and flies, as well as spiders and snails. The bird eats seeds from various weeds and berries from many plant sources, including mistletoe and poison oak, along with some cultivated fruits. Young grosbeaks are largely fed insects initially to support their growth.

Bird feeders

At bird feeders, the black-headed grosbeak may be attracted to a range of offerings, including sunflower seeds and suet. These high-energy food sources provide suitable nutrition for the bird outside of its natural diet.

What does a black-headed grosbeak sound like?

The black-headed grosbeak produces vocalizations reminiscent of a robin but are faster, softer, and sweeter. These vocals include a richly warble song and a distinct call note, characterized by an emphatic, slightly metallic 'tick.' The bird's call patterns fall, rise, or undulate, giving its vocals a unique sound. The grosbeak typically produces sounds like chirps, chips, flutes, rattles, and whistles.

Cassin’s Finch

Haemorhous cassinii

How to recognise a Cassin's finch?

General appearance

Cassin’s Finch is a medium-sized finch with a distinctive appearance characterized by its sturdy build and conical bill. Its plumage is predominantly brown, with streaked back and wings, and a light belly. Observers can identify it by its split short tail and pointed wings when in flight.

Male vs female

Male Cassin’s Finches are striking with their bright raspberry-red crown which blends into pinkish-red on the throat and breast. This coloration is more vibrant during the breeding season. Females, in contrast, lack the red hues, displaying streaked gray-brown plumage overall with distinctive facial markings, such as a pale eyebrow line and streaked underparts.

Juvenile

Juvenile Cassin’s Finches resemble females but are paler and have a more buffy appearance. They are heavily streaked with brown both above and below. As they mature, juvenile males begin to develop their characteristic red coloration. Seasonal variations include paler tones during the non-breeding season. They can be identified by their habitat in highland coniferous forests and their distinctive, warbling song.

Size

6.3 - 6.7 in/0.8 - 1.2 oz

Habitat

Primary habitat

Cassin’s finch primarily inhabits high mountain coniferous forests, often near the treeline. It prefers spruce and fir trees, along with pine and Douglas-fir in some regions.

Additional range

In winter, the bird resides in conifer mountain forests, occasionally migrating to open woods in lower valleys. It is also known to inhabit pinyon-juniper woods.

Range Map

What do Cassin’s finches like to eat?

Natural diet

Cassin's Finches primarily consume seeds, buds, and berries. Their diet mainly consists of vegetable material. They commonly eat the buds of various trees, which often form a staple part of their diet. Seeds from many trees, particularly conifers, are also significant in their diet, along with seeds from weeds. In addition to seeds and buds, they feed on berries and small fruits when these are available. During the summer months, their diet may be supplemented with insects.

Bird feeders

At bird feeders, Cassin's Finches might consume a variety of seeds commonly offered. These could include sunflower seeds, nyjer (thistle) seeds, or mixed seeds. They might also be attracted to suet or fruit provided at feeders, although these are not primary components of their natural diet.

What does a Cassin's finch sound like?

The Cassin’s finch vocalizes with a series of warbles akin to the Purple Finch, but with a flutier, more varied tone. Its signature call note is a high, distinctive "pwee-de-lip." The finch exhibits a complex call pattern, encompassing falling, rising, and undulating notes. The call types range from chatter, chirp or chip sounds, to a 'hi' note, trills, and whistles.

How to tell the Black-Headed Grosbeak from the Cassin’s Finch

Visual differences

The Black-Headed Grosbeak (7.5 inches, 1.4-1.8 ounces) is larger than the Cassin's Finch (6.3-6.7 inches, 0.8-1.2 ounces). The Grosbeak exhibits vibrant orange, black, and white plumage with a robust bill. Males have a black head, while females have tan with orange undertones. The Cassin's Finch is brown with a raspberry-red crown for males, with gray-brown streaking for females and juveniles. It has a conical bill, pointed wings, and a split tail. The differences in size, coloration, and bill shape are key identifiers.

Key differences and behavior

Black-Headed Grosbeaks and Cassin's Finches exhibit distinct behaviors and habitats. Grosbeaks, found in oak woodland and mixed forests, are active parents with both sexes sharing incubation and feeding. Their diet includes insects and seeds, and they enjoy sunflower seeds at feeders. Cassin's Finches inhabit high mountain coniferous forests and show flocking behavior, often around mineral deposits. These finches nest in conifers and adjust breeding locations based on food availability. They primarily consume seeds and buds, occasionally supplemented by insects in summer, and are less insect-dependent compared to Grosbeaks. While both species nest in trees, Grosbeaks prefer deciduous trees at lower heights (10-12 ft), while Cassin's Finches use conifers, often higher (30-40 ft). Grosbeaks display territorial singing during mating, unlike Cassin's Finches, which form colonies.
