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 intraspecific territoriality. 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.

This group of inconspicuous little birds can indeed serve as one of the most striking illustrations of the history of the formation of species. In Charles Darwin we read about this: “Observing this gradualness and difference in structure within one small, closely related group of birds, one can really imagine that due to the initial small number of birds on this archipelago, one species was taken and modified in different purposes ". A year earlier, Darwin wrote in a letter that the picture of the distribution of animals in the Galapagos Islands and the nature of the fossil remains of mammals found in South America impressed him so much that he began to stubbornly collect all kinds of facts that could, in one way or another, solve the problem that, in fact, represents a view. “Finally, enlightenment came over me, and now I am almost convinced (quite contrary to my initial opinion) that the species (this
