The black-billed magpie (Pica hudsonia), also known as the American magpie, is a bird in the corvid family found in the western half of North America. It is black and white, with the wings and tail showing black areas and iridescent hints of blue and blue-green. It was formerly treated as a subspecies of Pica pica (Eurasian magpie), but was separated as a species in its own in 2000 based on genetic studies. This species prefers generally open habitats with clumps of trees, but can also commonly be found in farmlands and suburban areas. Historically associated with bison herds, it now lands on the backs of cattle to glean ticks and insects from them. Black-billed magpies commonly follow large predators, such as wolves, to scavenge from their kills. The species also walks or hops on the ground, where it obtains food items such as beetles, grasshoppers, worms, and small rodents. The black-billed magpie builds domed nests which are made up of twigs and are located near the top of trees, usually housing six to seven eggs. Incubation, by the female only, starts when the clutch is complete, and lasts 16–21 days. The nestling period is three to four weeks. Black-billed magpies in the wild have a lifespan of six to seven years. Black-billed magpies have a long history with humans, being featured in stories told by Indigenous tribes of the Great Plains. Where persecuted it becomes very…

Increase of clutch size triggers clutch destruction behaviour in common moorhens (Gallinula chloropus) during the incubation period. Conspecific brood parasitism (CBP) is common in a variety of animal taxa, including birds. In coots ( Fulica spp.), and the closely related moorhens ( Gallinula spp.), such parasitism is especially common, and hosts experience considerable costs through increased chick competition soon after hatching. Hence, these birds have evolved egg recognition and rejection abilities, e.g., egg counting, burying the foreign eggs, assigning them suboptimal positions within the mixed clutch, or deserting parasitized clutches. For common moorhens ( Gallinula chloropus ) it h…
