The female cowbird may continue to observe this nest after laying eggs. Some bird species have evolved the ability to detect such parasitic eggs, and may reject them by pushing them out of their nests, but the female cowbird has been observed to attack and destroy the remaining eggs of such birds as a consequence, dissuading further removals.

Indigo buntings abandon their nest if a cowbird egg appears before they lay any of their own eggs, but accept the egg after that point. Pairs with parasitized nests have less reproductive success. The bunting chicks hatch, but have lower survival rates as they must compete with the cowbird chick for food. [28]
The brown-headed cowbird is an obligate brood parasite; it lays its eggs in the nests of other small passerines (perching birds), particularly those that build cup-like nests. The brown-headed cowbird eggs have been documented in nests of at least 220 host species, including hummingbirds and raptors.
The screaming cowbird frequently parasitizes its main host, the baywing, during the pre-laying period. [20] Screaming cowbirds lay 31% of their eggs before the first baywing egg but most of the eggs laid are ejected, and often within 24 hours. [29] By ejecting parasitic eggs with their feet, baywings can reduce the parasitic egg load by 75%. [30]
The shiny cowbird's diet consists mainly of insects, other arthropods [4] and seeds, and they have been recorded foraging for grains in cattle troughs. [2] Like most other cowbirds, it is an obligate brood parasite, laying its eggs in the nests of many other bird species such as the rufous-collared sparrow. [5]

If the eggs happen to hatch, the parents will immediately start feeding them fish and keeping them warm. If the eggs don't hatch, the parents will slowly start leaving the eggs a little bit at a time.
