There are many beliefs and predictions connected with bats: they beat out the window and walls — wait for the rain, flew into the house — for money and luck, if the bat flew to the wedding, this sign was unpleasant for the couple. According to ancient beliefs, life together will be either unhappy or very short. Scientists argue that these creatures never visit places with poor energy. Therefore, if a bat is in your house, a sign is a good one. So, in your house there is no negative, and only pleasant events await you.
There are bats in Kamchatka too. Today we will meet Brandt’s little animal, the night lamp, which is listed in the Kamchatka Red Book.
Brandt's nightlight (lat.Myotis brandti) is a small bat of the genus night.
This insectivorous mammal on average weighs from 5 to 9 grams (less than two teaspoons of sugar), body length 38-55 mm, tail length 31-45 mm, forearm length 33-39 mm, wingspan 19-24 cm, but can live up to 40 years old. This is about the same as a dolphin lives, and more than a horse or a cow. Brandt's night lamp takes a relatively long time to reach puberty. As a rule, one female produces one cub, whose weight at the time of birth is approximately one seventh of the weight of the parent.
Ear of medium length, tapering to the end, with a notch at the rear edge. The mask is covered with dark hair. The claw foot is approximately equal to half the lower leg. The wing membrane is attached to the base of the outer toe of the foot. The fur is thick, long, slightly disheveled. Hair with dark bases, back color from reddish to dark brown, belly from grayish to fawn-whitish.
Brandt’s night lamp can be found starting from England and the east of Spain through the Urals and Southern Siberia to Kamchatka, Sakhalin, Japan and Korea.
It is tied to mixed and deciduous forests, but penetrates the floodplains into the taiga and steppe. Shelters - hollow trees, hollows, rock crevices, less often - buildings. Flies out to hunt after thickening of twilight. It hunts flying insects in the forest over gaps and clearings at the level of crowns or between trunks, in parks, and also low over the mirror of water bodies. The flight is smooth, leisurely, maneuverable. Echolocation signals of low intensity in the range of 80-35 kHz, with a maximum amplitude of about 45-50 kHz. Saddled, winters in various underground shelters. Mating after lactation or wintering. Breeds in the early to mid-summer, brood colonies of up to several dozen females, males usually keep apart. In the brood, 1 cub, lactation for about 1.5 months.

Mammals of Kamchatka: Brandt Night Myotis brandtii (Eversmann, 1845)
Finds of Brandt's night lamp: 1 - reliable, 2 - false
Spread. The exact boundaries of distribution in the region have not been established. Reliable findings are known for the southeastern part of the peninsula, to the extent limited from the west and northwest by the valleys of the Kamchatka and Bolshaya rivers (1–4). Separately, for the coastal zone of Western Kamchatka there is an indication (5) approximately for the area of \u200b\u200bthe river. Duck. Presumably, the bats, observed north of the indicated area, should be attributed to Brandt’s night: they are common in the middle part of the basins of the Palana, Tigil, Belogolovaya, Moroshechnaya, Vorovskaya, Krutogorova, Ozernaya (East) rivers, and were observed in the north of Karaginsky Island. In the late 1970s. A passenger entered or brought in by a vessel was captured in the village. Nikolskoye on Bering Island (not preserved) (4, 6–8). In continental areas, bats are rare and sporadic. Single observed in the village. Upper Pahachi, repeatedly - in the village. Achayvayam and the bay of Natalia, as frequent - in the village. Manila, Tilichiki, Corf (4, 8, 9).
Appearance. The sizes are small. The main parameters of the body and weight are slightly less than that of the northern skin (partially overlap). The length of the forearm is 34.1–38.0 mm. Body weight 3.1–12.0 g. The ear, stretched forward along the head, protrudes 1-3 mm beyond the tip of the nose. The tragus is long (more than half the length of the ear), pointed, evenly tapering to the apex. The color of the back is brownish-brown, the underside is brownish-gray. Young ones are darker (1, 10).
Habitats and lifestyle. They are mainly confined to lowland forests and forested floodplains. It is more often observed along forest roads, along the edges of the river, over small ponds. Penetrates into the mountains at least up to 1200 m above sea level. m., possibly higher. Day shelters and brood colonies in hollows, fissures of various species of large trees. Variable, random shelters are diverse: on trees under nests of large birds, in cracks of coastal cliffs, under exfoliated bark of birches, etc. The optional synanthropus. Even in the absence of restrictions with natural shelters, he willingly settles in the buildings of man. Biology in the region is almost unstudied. In summer colonies, up to 25 individuals are found. Cubs are born in late June - July and usually stay with females at least until the end of August. In Eastern Kamchatka, spring emergence is usually registered no earlier than the end of May, the most recent meetings are until the second decade of October, and occasionally in the first decade of November (8, 11, 12). The nature of the stay in the region is not clear. Reports of extensive caves with a stable microclimate (13) are not supported by modern data.
Cases of successful wintering of individual animals in vegetable stores are known. The available isolated facts of the detection in October - November of numbing bats (in residential buildings and in hollows of trees) do not clearly prove the success of wintering. Moreover, death was noted in light, unheated buildings. In September 1996, at the Lopatkinsky ridge. In the elfin zone, a large accumulation of bats was noted (hundreds, according to eyewitnesses), which makes it possible to very cautiously assume the possibility of autumn migrations from Kamchatka to southern latitudes (4, 8).
Strength and limiting factors. In the Kronotsky Nature Reserve, on the forest road in the stony birch forest, 5.0–5.2 nights per 10 km of the route were taken into account (11, 12). In floodplain biotopes of the middle course of the river. Kamchatka (pos. Milkovo, Lazo) the incidence is much higher. The death of animals in colonies arranged in human buildings is often due to ruin or constant anxiety. In the Kronotsky Reserve, finds of dead young animals near brood colonies located in natural shelters were repeatedly noted. In the cities of Yelizovo and Petropavlovsk-Kamchatsky, the occurrence of night-nights has sharply decreased over the past 12–15 years, most likely due to the worsening state of the air environment and a noticeable decrease in the number of nocturnal insects. In part, a possible reason for the decline in numbers is the introduction of sparrows and, as a result, noticeable changes in the composition of the background species of the entomofauna of the urban zone (8).
The scientific and practical importance of species conservation. The study of biology and distribution will expand knowledge of the nature of the formation of modern theriocomplexes in the region. Exterminating a mass of blood-sucking dipterans and other harmful insects is a useful animal that deserves special protection measures. Within the boundaries of large settlements it is an identifier type of air quality, therefore, it can be successfully used as an object of monitoring.
Taken and necessary security measures. Since 1983, Brandt's nightlight has been included in the list of animal species to be protected in the Kamchatka Region. Along with other representatives of the fauna, it is protected on the territory of the Kronotsky Biosphere Reserve. It lives on the territory of Klyuchevsky Natural Park. In order to clarify the real distribution boundaries in the region, it is necessary to organize a systematic inventory of the species composition of bats in the protected areas, primarily the northern ones. Also - biology research and clarification of the main limiting factors, explanatory work among the population.

The sizes are small. The length of the body is 39–55 mm, the tail is 32–44 mm, the ear is 13–15.5 mm, and the forearms are 32–39 mm. Weight 3–12 g. The ear with the tip extended, stretched forward, extends beyond the tip of the nose, there is a noticeable notch on its outer edge; 4–5 transverse folds; the tragus is tapered pointed, long, exceeds half the height of the ear. Two small pre-molars on the upper and lower jaws are almost the same size. The wing membrane is attached to the base of the outer toe of the foot, the foot is small. The coat is of medium length, even, on the back of brown tones, without gloss, on the abdomen of dirty gray color; the end of the muzzle is gray. In adults ♂the penis is bulbously dilated in the lower part.
Spread
The main part of the global range is located in the northern Palearctic, occupying a strip of boreal forests from Great Britain and northern France to Kamchatka, its southern border passes through Italy, Bulgaria, Central Ukraine, the forest-steppe strip of Russia and northern Kazakhstan. The Caucasian part of the range is considered to be isolated and occupies, in addition to the North Caucasus, also Transcaucasia along the border with Iran. The Russian Federation contains most of the global range of Brandt's nightlight. Brandt's night lamp was found in 7 points of the KK: pos. Psebay; R. Pshish in the vicinity of Kurinskaya station; Babailovskaya and Tryu-52 caves; floodplain p. Shah in KGBPZ; Cave Canyon in the Absheron district.Features of biology and ecology
A sedentary species closely associated with woody vegetation and forest landscapes. For habitats, it prefers untouched broadleaf and mixed forests with rich undergrowth and nearby ponds. When hunting, it uses linear elements of landscapes - clearings, riverbanks, hedges, etc. Summer shelters in hollows or in human buildings, vodka colonies from 20–80 ♀, in the brood one cub. Fodder land of a large brood colony is about 100 km2. In the Caucasus, animals usually winter alone, hiding in the crevices of the ceiling and walls in caves and adits.
Abundance and its trends
Analysis of subfossil material from the caves suggests that until recently Brandt’s nightlight was a mass species in the territory of the KK. Now the number is not high, however, data are insufficient to draw conclusions about trends in its changes.Limiting factors
Decrease in habitat area due to deforestation of primary forest massifs, decrease in the number of summer shelters caused by deforestation of old hollow trees. Reducing the number of caves - winter shelters due to anxiety during their uncontrolled visits by tourists, arrangement and operation of excursion purposes, archaeological excavations. The use of pesticides in agriculture and forestry, the treatment of wooden structures with insecticides is negatively affected.Necessary and additional security measures
Similar to those for long-eared nightlight (M. bechsteinii).Sources of information

Spread. In the Moscow region widespread view. In the late XIX - early XX centuries. in the territory occupied by modern Moscow, Brandt’s nights were caught in Losiny Ostrov, Izmailovsky menagerie, Perov, in the garden of the Geer almshouse on V. Krasnoselskaya st. (2-4).
In the 1940s they lived in the crevices of the walls of the Novodevichy Convent (5). In the spring of 1986, Brandt’s nights were marked when they left the wintering grounds in Lefortovo Park and the Vorobyovy Gory (6); in the summer of 2010, an adult animal was found in okr. Vorontsov Park (7). Other reliable data on the presence of the species within the city of Moscow in 1985-2010. no, but we can assume its habitat in some natural areas with water bodies - in Losiny Ostrov, Izmailovsky forest, Kuzminsky forest, Uzky, Znamensky Sadki, Vorobyovy Gory, Fili-Kuntsevsky forest and Serebryany Bor
.Number. In the Moscow Region as a whole, the species is very numerous (8-10); its abundance in Moscow is not known. Along the Moscow River on the Vorobyovy Gory in the spring, when Brandt’s nightlight came out from the winter, in 1986, 20–30 was recorded. per 1 km of the route; in early May, only a few animals were recorded there (8). It is assumed that in the relatively large forest areas of the city with water bodies, the number of species can be close to that in similar habitats outside of Moscow.
Habitat features. As in natural conditions, in Moscow it prefers old-aged mixed and deciduous forests with hollow trees located near water bodies. In summer, small groups or alone settle in hollows of various configurations, less often in crevices under roofs and behind the wall cladding of wooden buildings. It hunts not far from its shelters over rivers and ponds, at the edges, clearings and clearings, among trees in sparse forests and old parks. It feeds on a variety of small flying insects and lives in places with their high concentration. He does not make long-range seasonal flights. In Moscow, it can winter in the basements of houses and other shelters, where the air temperature does not fall below zero.
Negative factors. Strengthening the urbanization center, parts of the Moscow region with an increase in area and density of development. Within Moscow, urban development of the territories adjacent to the forests without preserving the buffer non-adjustable strip along the edges of the forest. Technogenic pollution of water bodies and the air basin, sanitary treatment of ponds, especially in old parks, and the resulting significant reduction in the number of flying nocturnal insects - objects of feeding bats.
Transformation or degradation of natural and close biotopes along the banks of rivers and reservoirs, including as a result of bank protection with the destruction of near-water vegetation. Overgrowing in large forests of glades and glades with woody plants, lack of shelters due to the limited number of old hollow trees. Lack of data on the distribution and state of the species in Moscow and the impossibility of taking targeted measures to preserve it in this regard
.Security measures taken. On the territory of Moscow, the species was under special protection from 1978 to 1996, in 2001 it was listed in the Kyrgyz Republic 4. Territories with potential habitats for this nightlife have the status of protected areas - Losiny Ostrov NP, Izmailovo P-FE , "Kuzminki-Lublino", "Bitsevsky Forest" and "Moskvoretsky", PZ "Vorobyovy Gory".
View state change. To assess the change in the state of the data type, there is no data; its RC remains unchanged - 4.
Necessary conservation measures. Conducting special studies to determine the distribution, abundance and habitat of bats in Moscow. Purposeful searches for a view of the protected areas of Moscow and the identification of discovered habitats in the memory. Compliance with the requirements for the placement of buildings no closer than 30-50 m from the edges of the forests during the reconstruction of residential areas in the territories adjacent to the protected areas. Preservation of hollow trees in the coastal zones of rivers and ponds on existing and planned protected areas.
Regulated mowing of forest glades, wide clearings and floodplain meadows, preventing their overgrowing by trees and shrubs. Development and implementation of measures to reduce pollution of rivers and reservoirs in protected areas. Ban on sanitation of water bodies in protected areas. In the improvement of river valleys - the preservation of ancient reservoirs and areas with natural floodplain vegetation, hollow trees; on existing and project protected areas - environmental restoration of rivers and reservoirs, the banks of which are reinforced with gabions and vertical moss walls, with restoration of conditions for the emergence and development of near-water vegetation.

Smooth-nosed family (Vespertilionidae).
The range of Brandt's bedside lamp is very peculiar and insufficiently studied. It lives in the countries of Central, Northwest (Great Britain) and in all countries of Northern Europe. The eastern border of the range extends along the eastern part of Poland and somewhere in the limits of the Belarusian Lake District sharply bends to the east, following almost in a strictly latitudinal direction to Japan inclusive. Moreover, east of Belarus, the distribution of the species is represented not by a continuous range, but by individual islands. It is precisely this pattern of distribution that has been established for the nightshades of Moustached and Brandt in northeast Poland.
According to previous ideas, the eastern border of the range of this species passes through the west of Belarus. Belarus was included in the list of bats on the basis of an analysis of collection fees made in 1955-1980. in Belovezhskaya Pushcha. In other areas of Belarus has not been observed previously. In the entire history in Belarus, only 1-3 specimens of this species have been reliably identified.
However, new data clarified the geographical distribution in Belarus of Brandt's nightlight. As research activity increased, finds began to appear in other regions. So, in July 2003, an adult male Brandt nightlight was caught in the Petrikovsky district of the Gomel region. In August 2012, 5 adult individuals (4 females and one male) Brandt's nightlight were caught in the Zhitkovichi district of the Gomel region. in the territory of NP Pripyatsky. Finally, in June-July 2015-2016. in the Zhitkovichi region, on the territory of the Old Zhaden nature reserve, 12 adult Brandt nights were caught, of which 8 were lactating and pregnant females, which confirmed the reproduction of this species in the Pripyat Polesye region.
At the moment, the find of Brandt’s nightstand in the PSPEZ is the easternmost of the registration points known in Belarus. Based on the data obtained, it can be argued that the species lives throughout the territory of Belarusian Polessye from its western to eastern borders. Further east, in the Bryansk region of Russia, Brandt's nightlight was also repeatedly registered by researchers. South of Belarusian Polesie is extremely rare. So, in the Ukrainian part of the resettlement zone of the Chernobyl NPP, only 1 instance of Brandt's nightlight was caught in the course of very intensive long-term work on inventory of the bats fauna.
It is a rare breeding species in PRGEZ. Distributed in the reserve very locally, but in the habitat is one of the dominant species according to the results of detection. It was noted only in 2 localities confined to old-aged oak forests, alternating with swampy depressions in the relief in the Khoiniki and Narovlya districts. On June 25, 2016, a lactating female was caught in the Khoyniki district, and a pregnant female and an adult male were caught in the same place on June 14, 2017. The morphometric characteristics, the structure of the dental system, and the coloration of these individuals fully corresponded to the species-specific characteristics of Brandt's nightlight. Maternal colonies of this species were found, arranged in fissures and behind the lagged bark of old oaks.
Rare, sedentary - little studied species of bats. This species has not been found in Moldova and Ukraine. In Lithuania, this species is considered rare, but it hibernates in the west and in the center of this country. Further north, Brandt's nightlight becomes a more common sight.
The search for Brandt's night lamp in Belarus most likely can be crowned with success primarily in the territory of the Belarusian Lake District.
For a long time the status of this species in the domestic literature has been debated. Until 1980, Brandt's nightlight was considered a subspecies or synonym for a whiskered nightlight. At present, the complete independence of these two species has been proven.
One of the smallest nightlights in Europe. The sizes of Brandt's nightlight are as follows (from literature on Central European populations): wingspan 22-22.5 cm; body length 3.9-5.0 cm; tail 3.2-4.4 cm; ear 1.3-1.7 cm; forearm 3.3-3.8 cm; weight 5-10.5 g. Color from dark chestnut to black. The winged membrane grows to the base of the fingers (an important difference from the watery night).
From a close view - a mustached nightlight - it differs in several ways. Brandt’s nightlight is slightly larger, especially the forearm. The hair is dark brown to black. The tragus is obtuse with a convex posterior margin. The ear is relatively thin, translucent; pressed to the head, protrudes 1-3 mm beyond the tip of the nose. There is no epblem on the spur.
Caught animals in their hands are relatively calm and silent.
The ultrasonic signals of both types at the peak frequency coincide - 45 kHz.
The habitat habitats of Brandt and Moustached are similar. In the western part of the range, Brandt's nightlight is more inclined to forest stations, in contrast to the mustachioed, which prefers open. Flies to feed in the thick twilight, returns before dawn. It feeds on small flying insects: mosquitoes, midges, flies, small butterflies. Often grabs prey (for example, spiders) from the leaves of trees. In the summer you can find behind platbands of wooden buildings (in Belovezhskaya Pushcha).

This miniature creature belongs to the Batwing family, the family of ordinary bats, the genus of night-nights.
In general, Bats are the oldest animals on Earth. Scientists have proven that representatives of this detachment lived on our planet 55 million years ago. More truly, it was an animal similar to a bat, but it is still impossible to determine more precisely.
Brandt's night lamp was first described by Russian naturalist and traveler Eduard Eversman in 1845. But named after the German naturalist, zoologist, botanist and physician Johann Brandt. By the way, sometimes instead of Brandt’s nightstand they say: Brandt’s bat.
Description
This mouse with a body length of 4 to 5 cm, rarely more. The length of the tail is two-thirds of the length of the body. The weight of an individual varies from 5 to 10 grams.
This bat has a rather long ear, which tapers towards the end and has a notch at the back. Wool on the muzzle (mask) of a dark color. The fur of the whole body is thick, long, somewhat disheveled. The hairs have dark bases. Color variations on the back - from reddish to dark brown. Wings with membranes. Their scope is quite large - up to 24 cm. Apparently, therefore, describing the flight of the nightlight, zoologists note primarily its slowness.
With relatively calm living conditions (except for the main enemy - man, bats do not have many natural enemies) can live about 20 years.
Brandt’s colony of night-nights looks like, the photo in the article fully demonstrates.
Females of this species usually do not form the largest colonies - only up to several tens of individuals (for comparison: some bats gather several thousand individuals). As for the males of the nightlight, they usually stay alone.
In the litter of Brandt’s nightstand, there is one cub whom the mother feeds for a month and a half.
Habitat
The habitat is very extensive: England, Europe, Siberia, Korea, Japan, Sakhalin. There are known finds of specimens of this species on the lands of the Northern Urals, in the Khanty-Mansi Autonomous Okrug.
Lives in the hollows of trees in both forest and forest-steppe areas. It can settle in rocky crevices, caves and quite rarely in buildings. But for the winter it is arranged most often underground.
Begins the hunt in twilight. Its prey is flying insects. It can pursue the victim among the crowns of trees, and above the water. The flight of this creature is smooth and maneuverable.
According to the classification in the Red Book, Brandt's nightlight in different regions is most often classified as "a rare species with a limited, possibly intermittent distribution in different areas." Its distribution has been little studied, however, meetings are rare.
Features
The Batwing in general hunts and moves, and Brandt’s nightlight in particular, emitting ultrasonic signals. Encountered by an obstacle (insect, wall, etc.), the impulse returns, like an echo, captured by the animal - thus information about the object enters the brain. Echolocation serves a bat like a flashlight emitting rays of light in different directions. With the help of a series of short signals of different frequencies, the bat is able to move and navigate even in complete darkness and confined space (cave). Here the need for vision recedes into the background.
It is clear that the ability to echolocation have more insectivorous bats, in particular Brandt's Night. Some fruit-eating and nectar-eating species living in open spaces calmly do without it.
In addition, scientists have proven that the sounds made help bats also coexist in the colony - that is, communicate. And the presence of a certain social behavior implies sounds of different heights, loudness, and totality. All this animal must be able to distinguish and understand. And Brandt's Nightstand is no exception in this case.
Observation
A lot of information about the Bats was collected, but Brandt’s Nightlight is still poorly understood. Data on abundance, habitat, and behavior are based on reliable, but not completely systematized encounters.
Part of the matter is that the Batwing is the richest and most prolific Mammal detachment in speciation. For example, Brandt’s nightlight is quite difficult to distinguish from another nightlight - Usata.
In addition, collecting data on these creatures and observing them is difficult. These are nocturnal animals, secretive, hibernating in winter. In addition, Brandt's nightlight is also quite small in size.
Human urban and economic activity often destroys bat colonies, which are usually attached to the same place of settlement. That is why many species of Batwing are listed in the Red Book.
