Interspecific bird conflicts are explained by competition and hybridization
Many animals jealously guard their territory from the invasion of strangers. This is logical when it comes to a representative of its own species. However, an individual belonging to a different species often becomes the object of attack. For a long time, it was believed that such interspecific territoriality was just a by-product of the intraspecific one. In other words, the owner attacks the stranger by mistake, mistaking him for a relative.
However, new evidence suggests that protecting an area from other species is adaptive. It can arise and persist when different species compete for a particular resource, such as food or shelter.
A team of zoologists led by Jonathan P. Drury of the University of Durham conducted a massive study of interspecies competition for territory using the example of North American passerines. After analyzing the literature, scientists found that this behavior is typical for 104 of their species. This is 32.3 percent of the total number of passerine species in North America. Thus, interspecies competition is more widespread than previously thought.
According to the authors, in most cases, birds come into conflict over territory with a representative of one specific species. There are several factors that increase the chances of forming a pair of competing species. For example, birds that live in the same biotope, have similar sizes and nest in hollows are more likely to be involved in conflicts over territory. For species belonging to the same family, another factor plays an important role - the probability of hybridization. If two species are capable of interbreeding with each other, their males are likely to react aggressively to each other.
Based on the data obtained, the researchers concluded that interspecific conflicts for territory among birds do not arise by mistake. This behavior is an adaptive response to competition for a limited resource, as well as a mechanism to prevent hybridization between closely related species.
Cardinal red-billed weaver
A small bird about 10 cm long. It has a short and heavy black beak. In breeding plumage, the male has a purple-red head and part of the breast. Outside the mating season, its plumage is colored in the same way as that of the female, but some red color remains on the head. The female has a yellow face.
These birds breed in colonies. The nest is built from soft blades of grass right among the grass or in the bush. In clutch there are 2 - 3 eggs of lilac, pink or blue color with dark specks. The incubation period lasts 14 days. After that, the chicks remain in the nest for another 24 days. Parents feed them with insects.
