We determined the population density and number of Eurasian Eagle-Owl in one of the regions of Russia (Republic of Mordovia). The work was carried out over sixteen years (2009 – 2024). The studies were conducted using methods of direction finding of vocalizing birds with subsequent search for nests and with the use of digital voice recorders. The E...

The data of a study of the ornithological situation in the vicinity of the airfield of Saransk International Airport in the winter of 2023-2024 are presented. The species composition, places of mass concentration, directions of daily migrations and the influence of climatic conditions on the activity of corvids were determined. The largest number o...

Relevance: to prevent cases of bird collisions with aircraft at airports and their environs, it is necessary to constantly monitor the bird population, identifying the species composition and relative abundance, as well as determining migration routes and natural and anthropogenic features of airports. The article presents the results of an ornitho...

The success of Eagle Owl breeding in artificial niches and natural nests was studied. Manufacturing and installing artificial nests for Eagle Owls in Mordovia, central European Russia is employed as a factor to increasing the number of both successfully breeding pairs and the population size. At the same time, no differences were found for artifici...

The article considers the co-vocalisation of Eagle Owl and other species of owls. The studies were carried out using digital voice recorders in the habitats of the eagle owl. The natural and climatic conditions of the area in which co-vocalisation was noted were analyzed. Rare cases of co-vocalisation of Eagle Owl and its prey, primarily the Ural O...

From the standpoint of studying relationships in the “predator-prey” system, joint vocalizations of predator birds and their potential prey are of particular importance. However, there is still very little information in the scientific literature about adaptations to the co-vocalisations of Eagle Owl and other bird species that do not belong to the...

Численность филина в Мордовии до недавнего времени была сильно недооценена. На 2016 г. определено обитание филинов в 46 точках. В юго-восточной части республики на 80% обследованной территории радиусами гнездовых участков в 2-3.5 км полностью закрывается вся площадь.

A new method and new techniques are proposed for making artificial nests for Eagle-owls to increase their population. Artificial nesting sites allow Eagle-owls to hatch their chicks successfully and stay in a certain area. The results of field studies show that one of the decisive factors for large owls is the presence of a nesting site protected f...

Both daily and seasonal year-round vocal activity of Ural owl were recorded in the Middle Volga River Region, Russia with the use of digital dictaphones. Two best-expressed peaks of longterm activity were revealed during the year: one starting in March and the other in September. In the spring, calls were recorded from 19:51 to 04:04. During this p...

A new method and new techniques are proposed for making artificial nests for the Eagle owl so as to increase its population. Artificial nesting sites allow the Eagle owls to successfully hatch their chicks and stay in a certain area.

Both daily and seasonal year-round vocalizations of the Long-eared owl (Asio otus) (Linnaeus, 1758) were recorded in the Middle Volga River region, Russia with the use of digital dictophones. Voice recorders were installed in the daytime for up to 5 days. The maximum duration of continuous operation of voice recorders was about 140 hours. By the ti...

Small mammals are important reservoirs for zoonotic pathogens that cause significant morbidity in humans. Of these, tularemia and hemorrhagic fever with renal syndrome (HFRS) are among of the most widespread zoonotic diseases worldwide. Despite the fact that both pathogens have great epidemiological significance in Russia, epizootological data for...

A list of 40 species is presented of the rodents and insectivores collected during a 15-year period from the Republic of Mordovia. The dataset contains more than 24,000 records of rodent and insectivore species from 23 districts, including Saransk. A major part of the data set was obtained during expedition research and at the biological station. T...

Rabic infection currently determines the epidemic and epizootic state in many countries. In this study, we revealed the value of red fox (Vulpes vulpes Linnaeus, 1758) as a carrier of rabies in the forest zone. Altogether, the research was conducted in 22 districts and the city of Saransk during the period from 2009 to 2018. The work uses a compreh...

A new method of studying for activity of a semi-aquatic mammal Russian desman Desmana moschata (Linnaeus, 1758) with use of digital portable voice recorders is developed. To identify the burrows in which the recorders were to be installed, the burrows were probed. A probe is a pole pointed at one end with a T-shaped handle at the other end. The res...

To date according to the registration work, the number of the Russian desman determined actually is 588 individuals in Mordovia. Based on extrapolation, the total desman population in Mordovia is about 1,400 individuals. We may assume that the most of the desman population is concentrated on floodplain lakes and reclamation canals. The highest dens...

The results of identifying tularemia foci using the predatory bird pellets in the central part ot Russia using the example of the Republic of Mordovia are presented. The efficacy of tularemia detection in pellets compared with other biomaterials has been shown. The average content of the tularemia microbe antigen from the predatory bird pellets was...

Until recently, the number of Eagle Owl in the of Mordovia was greatly underestimated. To date, 65 habitats of an owl have been identified in the of Mordovia. At the inpatient department in agrolandscape conditions, the density of occupied areas was 3.6 per 100 km2, which is comparable with the density of Eagle Owl in the most optimal parts of the...

Embryonic and larval development of the Siberian sturgeon Acipenser baerii was studied at different salinity (0.5–10.5‰). It was noted that the salinity of the medium above 6.5‰ already in embryogenesis leads to malformations and complicates hatching of prelarvae. A marked increase in the sensitivity to salinity in prelarvae is recorded during the...

Both daily and seasonal year-round vocalizations of the eagle-owl were recorded in the central Volga River region, Russia with the use of digital dictophones. Two best-expressed peaks of long-term activity were revealed during a year: one since early February until early April and the other since early August until early October. During the incubat...

A new technique of eagle owl registration is offered based on acoustic signals recorded with the use of a portable digital voice recorder. The recorder allows recording the vocal activity of a large owl at a distance of 4 km from the place of installation to the screaming bird, depending on wind direction and speed, as well as on terrain relief. Th...

The dependence of the breeding success of the eagle owl on the population dynamics of rodents, which are a staple of its diet in Mordovia, was traced. At peak numbers of rodents, large clutches and a high survival rate of fledglings were observed in the breeding pairs; after a year of depression of rodent populations, in the following year, the pai...
