This Brown-headed Cowbird has a crossed bill. I wonder if it was raised by Red Crossbills? (Not likely but interesting!) #broodParasite #birding

This is a Brownheaded Cowbird, they don't build nests, they are brood parasites, laying their eggs in other's nests who then care for the much bigger chick.

Active defence mechanisms in brood parasitism hosts and their consequences for parasite adaptation and speciation
Obligate brood parasitism is a peculiar behaviour found in some bird species. The costs for their hosts can be high, generating selection for active defence strategies including foreign egg and chick....

Quick drawing of a brown-headed cowbird and chipping sparrow nestlings to show how being bigger puts the parasite's mouth closer to the host parent (& food).

In Procreate on iPad, referenced from the YouTube video linked below.
A digital drawing of four baby birds in an implied nest. All are too young to have their eyes open yet, and all have their heads raised and mouths open. One of the nestlings (a brood parasite) is much larger than the others and a slightly different color, easily reaching higher than the smaller host nestlings.

Cuckoos are brood parasites - laying eggs in the nests of other birds, which raise the chick thinking it is one of their own.

The bigger bird in this photo is the cuckoo chick being fed by its tricked, and much smaller surrogate mother.

A parasitic nestling Hodgson's hawk-cuckoo showing the patch of bare skin on its wing in a begging display. This mimics an open mouth to the host bird's eyes, so they bring more food.

There are VERY few (& small!) photos, so I drew this. 😄

A digital drawing of a single young bird sitting in a nest in a moss-covered tree cavity. The bird is a nestling Hodgson's hawk-cuckoo (Hierococcyx nisicolor), a brood parasite that replaces the host bird's young. The nestling's bright yellow mouth is open, and it has also raised one wing, the bare skin of which is the same color as its mouth (though in UV light it would actually be brighter). This mimics an open mouth and helps disguise the fact that there is only one nestling, which the host parents would otherwise be less interested in feeding.
