Their diet is mainly based on acorns. It is usually found in small family groups.
This species was nearly wiped out by human persecution and development between 1850 and 1920, but has since rebounded to become a common and familiar bird.

The nest is a hole that they dig in a tree chosen by the male, which is usually dry, but sometimes, in urban areas, they do it on poles.

Introgression and intermediate forms often occur where different subspecies meet.

With queer antediluvian grunts they set wing, descending in majestic spirals to the welcoming wastes of a bygone age."

A foraging generalist, this species' diet consists largely of birds, mammals, and lizards. It is aggressive in the defense of its nesting territory, attacking animals as large as Golden Eagles (Aquila chrysaetos), Red-tailed Hawks (Buteo jamaicensis), and humans.
Enjoying the rain. It looks small in the photograph, and although it only weighs 10 grams, it is the largest hummingbird that can be found in northern Mexico.
They feed exclusively on flying insects, often at higher altitudes than other swallows. It captures and ingests its prey in flight.

In other words, they only have one partner.
The males share the tasks of the nest almost equally with the females.
Both males and females sing from the nest. The male chant seems to work mainly in the defense of the territory. Female song seems to work in communication between peers and family groups.
Occasionally, females sing a "male" song, apparently to mislead the pairs of intruders and force more attention on the nest. ߘΰߘ

Wintering flocks of up to 166 individuals per hectare feed on grains such as wheat and seeds from native grasses. In this plumage it is very difficult to observe them as they blend cryptically in their prairie habitat.
It searches for food among the branches of the pines, jumping slowly, which allows these flirty little birds to have good photo sessions.

It stands out more than the rest because it launches into the open field, emitting a loud uit-uit! from the tops of the mesquite trees. This cuitlacoche moves easily to the suburbs and cities as long as there is native vegetation, especially cholla cacti, its number one choice as a nesting site.

Everything about it is distinctive. The jet black breast and belly, the golden yellow back and striking head markings of the breeding plumage would in themselves be enough to set it apart in any assemblage of its relatives. In addition it has rather stately and dignified movements in contrast to the darting hasty nervousness of so many shorebirds whether feeding, migrating or on the breeding grounds. The downy chicks are also among the loveliest of all young birds, their yellow backs being startlingly different from the usual blacks, browns and grays affected by most newly hatched youngsters of the shorebird clan.
