THE NEW RED LIST OF BULGARIAN BIRDS: DOES THE NUMBER

OF ENDANGERED BIRD SPECIES INCREASE?

Tanyo MICHEV1, Zlatozar BOEV2, Nevena KAMBOUROVA3

Abstract. Since the composition of the 1st Red List of the birds in Bulgaria (BOJEW,

MITSCHEW 1980) over 30 years have passed during which the conservation status of the birds

has gone through considerable changes. The new Red list contains 155 bird species from the

following categories: Regionally Extinct (REX) – 10; Critically Endangered (CR) – 32;

Endangered (EN) – 45; Vulnerable (VU) – 53; Near to Threatened (NT) – 2; Local Concern

(LC) – 7; Data Deficient (DD) – 6. The number of the endangered species has increased up

from 28.2% to 38.1%. The speed of the growing up process is 0.89 %/year or 0.69

species/year. The conclusion is that conservation efforts have to be basically directed to

species from the category “Critically Endangered”.

Almost half of the birds in the new Red List are conventional Tertiary relicts. The Pleistocene

relicts are eight time less numerous – just about 6.45% of the species. Among them the

species which inhabit mountain-hill landscapes predominate.

The predominant part of the species belongs to 5 types of habitats. The largest number of the

species (1/3 or 31.6 %) inhabits wetlands in the inner part of the country. Forests take 2nd

place with 38 species (or 24.5 %) and rocky habitats and caves rank third place with 23

species (or 14.8 %).

Twenty-three zoogeographical types are presented in the new Red List proving the all-

embracing process of the impoverishment of the recent Bulgarian avifauna. The birds of

Paleactic distribution are the most numerous zoogeographical type, presented by 48 species,

followed by the Holarctic, European, Cosmopolitian, Turkestanian-Mediterranean and Old

World types (10-11 species each). The Palearctic type is the most numerous also within each

separate conservation category.

In Bulgaria as a whole the birds are most endangered in comparison with Greece and

Romania.

Introduction

The 1st Red List of Bulgarian ornithofauna was published by BOJEW, MITSCHEW (1980). It

contains 100 species which are grouped in three categories: extinct, endangered and rare. In

the subsequently published “Red Data Book of People’s Republic of Bulgaria” (BOTEV,

PESHEV 1985) each species is presented with a short article, a map and a drawing. Since the

publishing of the 1st Red List 30 years have passed during which the conservation status of the

birds of the Bulgarian ornithofauna has gone through considerable changes. The tracing and

analysis of these changes are the aims of the present article.

The new Red List was given to professional ornithologists and experienced amateurs who

have prepared specialized articles for particular species. The upcoming event is their release

as a separate volume from the 2nd edition of the three-volume “Red Data Book of the

Republic of Bulgaria”.

Methods

When the 1st Red List was prepared the categories in it were not consistent with the categories

of IUCN which were adopted subsequently. That sort of difference in the assessment of

conservation status, to a certain extent, bothered the objective comparison with: 1) the present

new Red List; and 2) the bird species status in neighboring countries of Bulgaria or from

different parts of species range.

The new Red List presented here follows the categories of IUCN and corresponds to their

application in the other countries. The Latin and Bulgarian names of the birds and their

arrangement follow the recommendation of the Bulgarian National Rarities Committee

(BUNARCO 2009).

Results

In the 1st Red List of Bulgaria (BOJEW, M ITSCHEW 1980) 100 bird species are included out of

all 354 species, established at that time. They represent 28.2 % from the species composition

of the Bulgarian ornithofauna.

The new Red List contains 155 bird species (see Appendix) or 38.1 % of all 406 species

reported for Bulgaria nowadays (BUNARCO 2009). Their belonging to different taxa (orders)

is represented in Table 1. Obviously, the most endangered are two groups of orders: diurnal

birds of prey (Accipitriformes, Falconiformes) and water birds (Podicipediformes,

Ciconiiformes, Gruiformes, and Pelecaniformes). The Galliformes as main hunting object is

also with quite unfavorable conservation status.

The species from the new Red List are assigned to 7 IUCN categories (Table 2). The

proportion between the separate categories is represented on Fig. 1. The most numerous

category is “Vulnerable”, followed by “Endangered”, Critically Endangered (CR) and s. o.

The number of species in the new Red List is decreasing with the increasing of the threat

degree (Fig. 2). As could be seen also from this figure, thirty-two species from the category

“Critically Endangered” are closest to the boundary of extinction as breeding species in

Bulgaria. Depending on the character and efficiency of the measures which will be taken for

their conservation in the next years these species will either “cross” the red line (and will be

put in category “Regionally Extinct”) or they will be returned to more slightly threatened

category. With this conclusion we direct the attention of the nature conservation community

in the country exactly to this group (“Critically Endangered”) where the conservation efforts

have to be concentrated.

The “Critically Endangered” category as well as the other categories is distinguished by some

distinctive characteristics which are considered further down.

Different categories own some characteristics which are considered further down.

Regionally Extinct Species (REX)

Ten species from 5 orders are listed in this category. They do not breed on the territory of the

country for many years. Three species are globally threatened (Table 3) and their names are

written in bold type. Two species (Tetrao tetrix and Phasianus colchicus) are resident and the

probability for recovery of their breeding population is insignificant without human

intervention. Conversely, all reasons for their present unfavorable conservation status are of

4

local character and these reasons are subject to influence in the bound of the country. All the

other species nowadays are found incidentally on the territory of the country or more

regularly during the migration and winter time. Some of the species try to breed again or even

there are records for successful breeding (Aegypius monachus and Pelecanus onocrotalus).

The probability of the Common Crane (Grus grus) to return as breeding species increase a lot

with the restoration of Dragomansko Blato after long years of semi-drain condition. There is

also a potential possibility for the recovering of Bearded Vulture (Gypaetus barbatus) thanks

to the elaboration of European and national nature conservation projects for its reintroduction

in parts of its former range in the country.

Critically Threatened Species (CR)

In this category 32 species from 11 orders are listed (Table 4). Charadriiformes is represented

with large number of species (8) and after them comes Anseriformes (5 species). Almost one-

third of the species are globally threatened. In the table the species names of globally

threatened birds are written out in bold type. This category is situated very close to the red

line which marks the critical boundary of extinction (Fig. 1) and has a key and crucial role for

the future of Bulgarian ornithofauna. In this category there are five species which are on the

edge of survival as breeding birds in the country: Aquila heliaca, Falco naumanni, Falco

vespertinus, Falco cherrug and Otis tarda. For three of them (Aquila heliaca, Falco cherrug

and Falco vespertinus) nowadays there are projects for recovering of their populations.

Endangered Species (EN)

In this category there are 45 species from 14 orders (Table 5). Charadriiformes is represented

with a largest number of species (9) and after that comes Anseriformes (6) and Passeriformes

(6). Here there is only one globally threatened species (Oxyura leucocephala). Despite the

nature conservation efforts one species (Neophron percnopterus) has fast decreasing

population and there is a real risk to disappear as a breeding bird from the territory of

Bulgaria. This necessitates its moving to the previous category of critically threatened species.

Vulnerable Species (VU)

Fifty three species of the new Red List belong to this category (Table 6). Here the passerines

and raptors are represented with the largest number of species. Four bird species (given in

bold type) are globally threatened.

Near to Threatened Species (NT)

5

In this category there are two species: Rallus aquaticus of Gruiformes and Corvus corax of

Passeriformes.

Species with Local Concern (LC)

Seven species are listed in this category. Again the largest number of species falls into

Charadriiformes (Table 7).

Data Deficient Species (DD)

Insufficiently studied are 6 species or 1.5 % from Bulgarian ornithofauna (Table 8). There is

one globally threatened species: Marmaronetta angustirostris from Anseriformes (its name is

in bold type).

Excluded species from the First Red List

Eight species presented in the 1st Red List (BOJEW, M ITSCHEW 1980) are not listed in the new

Red List (Table 9). One of them is Great Cormorant (Phalacrocorax carbo) – it is not

included in the New Red List due to the considerable increase of its number during the

breeding season, migration and winter. The other seven species breed occasionally (Asio

flammeus) or they are rarely wintering and migration species.

Other changes in conservation status of Bulgarian ornithofauna during the considered

period

Because of the differences between the categories used in both red lists we can make the

comparison only regarding the category “Regionally Extinct Species” (species which are

extinct as breeding in Bulgaria). The comparison shows that in spite of the same number of

species there is a difference in species composition. Instead of Common Snipe (Gallinago

gallinago) and Pygmy Owl (Glaucidium passerinum) in the new Red List are listed two other

species – Red-crested Pochard (Netta rufina) and Pallid Harrier (Circus macrourus).

The Common Snipe has fallen away from this category because it began to breed again in the

country after the recovering of Dragomansko Blato (IANKOV 2007). In the past it occurred

regularly there (REISER 1894). The Pygmy Owl has fallen away from this category because

vital breeding populations in the central part of the Balkan Mountains, Rila Mountain, South

Pirin and the Rhodopes (IANKOV 2007) were found. In this category Pallid Harrier (Circus

macrourus) is included which in the past bred in Dobrudzha near the Village of Dubravino,

Varna District (BOEV 1962) but by indistinct reasons this species was not listed in the 1st Red

List of Bulgaria.

6

The Red-crested Pochard is included in the new Red List in the considered category, because

it does not breed on the territory of the country any longer. The species is also listed in the

Red Data Book of Romania (BOTNARIUK, TATOLE, EDS 2005) as “endangered species”.

Despite that White Pelican (Pelecanus onocrotalus) and Cinereous Vulture (Aegypius

monachus) are found occasionally to breed in Bulgaria (SIMEONOV et al. 2001; МARIN et al.

1993) because of the still casual character of their breeding, these two species are still

considered to be regionally extinct.

Discussion

Conditionally we can compare the group of the endangered species from the 1st Red List

(BOJEW, M ITSCHEW 1980) – 57 species with the combined group of “critically endangered”

(CR) and “endangered” (EN) – generally 77 species from the new Red List. The increase is

with 20 species that can indicate raised anthropogenic pressure on the Bulgarian ornithofauna.

Comparing with 1980 there is an increase of 26 % that for the whole period amounts to

average speed of growing of about 0.89 %/year. This means that every year 0.69 species is

added to the list of the endangered species in the country or every 1.45 year (at every 17.4

months) one bird species from the Bulgarian fauna has been found to be critically endangered.

The fossil record indicate that the conventional Tertiary relicts in the country should relate to

recent representatives of 17 genera: Accipiter, Gyps, Circaetus, Porzana, Actitis, Galerida,

Lullula, Erithacus, Regulus, Sturnus, Pyrrhula, Parus, Carduelis, Fringilla, Coccothraustes,

Loxia and Melanocorypha (BOEV 2002, 2007; BOEV et al. 2007) which are recorded on the

territory of the country in the pre-glacial times. From them representatives of 6 genera are

included in the new Red List which number 10 species (see Appendix). If towards the

Tertiary (sub-) Mediterranean ecological complex we also add the known from the Neogene

(MLÍKOVSKÝ 1996) 38 genera from other countries on the Balkan Peninsula or Europe

(Aegypius, Alectoris, Anas, Aquila, Ardea, Ardeola, Botaurus, Branta, Bubo, Buteo, Ciconia,

Columba, Corvus, Cygnus, Egretta, Eremophila, Falco, Gypaetus, Hieraaetus, Ixobrychus,

Larus, Neophron, Nycticorax, Otis, Pernis, Pelecanus, Phalacrocorax, Phasianus, Platalea,

Plegadis, Podiceps, Recurvirostra, Sitta, Sylvia, Tachybaptus, Tadorna, Tetrao and Tetrax), it

becomes clearly that exactly the species from these genera represent the main part of the new

Red List of Bulgaria. Thus, to the 10 species mentioned before we have to add other 66

species which belong to the 38 genera listed above. In this way the number of Tertiary relicts

in Bulgarian ornithofauna amount to at least 76 species or 49.03 % from the composition of

all endangered bird species in the Red List of the country. This fact has its own explanation,

7

first of all with geological past of the country. During the glacials in the Pleistocene vast areas

of the Balkan Peninsula and the country (especially the southern parts) represented refugia for

thermophilic Tertiary (Neogene) avifauna. A large part of its composition survived during the

Pleistocene and although partly with substitute composition most of the birds’ genera

inhabiting Bulgarian lands during the ,pre-glacial time, survived till nowadays. The observed

tendency of modifying and warming of the climate during the recent years (“globally

warming”) obviously is not in condition to assist the staying of this group of birds and the

reasons for the decreasing of its representatives have to be categorized as anthropogenic.

Thus, considering the composition of the new Red List we can conclude that as a whole

currently the faunistic elements with more “southern” origin, even though more numerous, are

seriously endangered in the country.

One hundred and sixty bird species (BOEV 2006; BOEV et al. 2007) are found in the

Pleistocene localities in Bulgaria. They represent 39.4 % of the present-day ornithofauna of

the country. In the group of Pleistocene relicts in the country according to TYRBERG (1991)

the following 7 species from the new Red List are included: Eremophila alpestris,

Pyrrhocorax graculus, Tichodroma muraria, Columba livia, Buteo rufinus, Aquila heliaca

and Anthropoides virgo. In the group of “cold-loving elements” (“boreal”) which survived in

the fauna of Europe from the early and middle Pleistocene MOURER-CHAIVIRÉ (1993)

concerned Tetrao urogallus, Lyrurus (=Tetrao) tetrix, Lagopus lagopus, L. mutus, Tetrastes

spp., Nyctea scandiaca (= Bubo scandiacus) and Pyrrhocorax graculus. According to BERON

(1969) Picoides tridactylus and Turdus torquatus are species with arctic-alpine distribution –

inheritance from the glacials of the Pleistocene. The first one is also included in the new Red

List. Thus Pleistocene relicts (10 species from the current list) represent 6.45 %. From them 4

species are in the category “Endangered” (Tetrao urogallus, Tetrtastes bonasia, Columba

livia и Picoides tridactylus) – all of them inhabit mountains; 4 species belong to the category

“Vulnerable” (Eremophila alpestris, Pyrrhocorax graculus, Tichodroma muraria and Buteo

rufinus) – all of them also inhabit mountains and hillside landscapes; 1 species belongs to the

category “Critically Endangered” (Aquila heliaca) and 1 species is extinct (Anthropoides

virgo).

From the conservation point of view it is important to trace out the distribution of species

from different categories in the new Red List by their nesting habitat types. For this purpose

we used the categorization of TUCKER & EVANS (1997) consistent with The EU Habitat

8

Directive (Table 10). The species were grouped under the most general habitat types because

a more detailed distribution is quite large and may be a subject of another article.

One may see from the table that the predominant part of the species belongs to 5 habitat types.

The largest number of the species (1/3 or 31.6 %) inhabits wetlands in the inner part of the

country. Forests take second place with 38 species (or 24.5 %%) and rocky habitats and caves

rank third place with 23 species (or 14.8 %).

An other aspect of the new Red List is the species ranking according to their zoogeographical

type of distribution (Table 11). We have used the classification of Voous (1960) and its

applying for Bulgarian ornithofauna by SIMEONOV & M ICHEV (1990), BOEV (1997) and BOEV

ET AL; (2007). As one may see the most numerous zoogeographical type in the new Red List

is the Palearctic type, presented by 48 species, followed by Holarctic, European,

Cosmopolitian, Turkestanian-Mediterranean and Old World (with 10-11 species). The

Palearctic type is the most numerous type also in each separate category. The other types are

presented by small numbers of species.

Definite interest represents the comparison between the number of species in the new Red

List of Bulgaria and the number of species in the Red Books of Romania and Greece (Table

12). Comparing the territories of the three countries the data show unfavorable condition of

the Bulgarian birds. Thus in Bulgaria there are over 1.397 species on every 1000 km2 while in

Greece they are almost two times less (0.757) and in Romania – over four times less (0.343).

These data should be taken into consideration regarding the territorial conservation of birds,

as well as all other conservation measures. There are objective preconditions for the last

mentioned. Across the territory of Bulgaria the boundaries of breeding range of 73 species

pass over. Through the country the southern boundary of the range for 37 species pass over,

for 30 species – the northern boundary, for 3 species – the western one and for 3 species – the

eastern boundary (BOEV 1997). Thus, only regarding the ornithogeographic reasons, the

biodiversity of the Bulgarian birds is several times more threatened which imposes the

acceptance of adequate measures for its conservation.

Conclusion

In the new Red List of birds in Bulgaria 155 species are distributed in 7 categories as follows:

Regionally Extinct (REX) – 10; Critically Endangered (CR) – 32; Endangered (EN) – 45;

Vulnerable (VU) – 53; Near to Threatened (NT) – 2; Local Concern (LC) – 7; Data Deficient

(DD) – 6. The number of species under threat increased from 28.2 % to 38.1 % in comparison

with the second half of the past century (the end of 1970-s). The conservation efforts have to

9

be directed basically towards the species from the category “Critically Endangered”. These

species need the elaboration and urgent implementation of particular plans for their

conservation in the country. For the 30-year period (1979-2009) the number of endangered

bird species in the country has increased with ¼. The speed of the increasing process is 0.7

species/year.

Almost half (49.03 %) of the composition of the new Red List of threatened birds in the

country belong to the conditionally accepted as Tertiary relicts in the present-day Bulgarian

ornithofauna. The Pleistocene relicts are eight times less – hardly 6.45 % from the species.

Among them the species which inhabit mountain-hill landscapes predominate. This fact has a

practical meaning – the efforts of territorial nature conservation of birds regarding the

conservation of glacial relicts, would have more significant success if they are exactly

directed in the semi-mountain and mountain regions.

The predominant part of the species in the new Red List belongs to 5 habitat types. The

largest number of the species (1/3 or 31.6 %) inhabits wetlands in the inner part of the

country. Forests take second place with 38 species (or 24.5 %) and rocky habitats and caves

rank third place with 23 species (or 14.8%).

Twenty-three zoogeographical types are presented in the new Red List proving the all-

embracing process of the impoverishment of the recent Bulgarian avifauna. The most

numerous zoogeographical type in the new Red List is the Palearctic type, presented by 48

species, followed by Holarctic, European, Cosmopolitian, Turkestanian-Mediterranean and

Old World (with 10-11 species). The Palearctic type is the most numerous type also in each

separate conservation category. The other types are presented by small numbers of species.

In Bulgaria as a whole the birds are most threatened in comparison with Greece and Romania.

In Bulgaria on every 1000 km2 occur over 1.397 species while in Greece they are almost two

times less (0.757) and in Romania – over four times less (0.343). Regarding

ornithogeographic reasons the biodiversity of Bulgarian birds is several times more threatened

which imposes the acceptance of adequate measures for its conservation.

Новият Червен списък на птиците в България: увеличава ли се броят на

застрашените видове птици?

Таню МИЧЕВ, Златозар БОЕВ, Невена КАМБУРОВА

(Резюме)

От съставянето на първия Червен списък на птиците в България (BOJEW, M ITSCHEW

1980) са изминали над 30 години, през които природозащитният им статус е претърпял

значителни промени. В статията е представен новия Червен списък, който съдържа 155

вида птици: Regionally Extinct (REX) – 10; Critically Endangered (CR) – 32; Endangered

(EN) – 45; Vulnerable (VU) – 53; Near to Threatened (NT) – 2; Local Concern (LC) – 7;

Data Deficient (DD) – 6. Броят на видовете под заплаха е нараснал от 28,2 % на 38,1 %.

Скоростта на процеса на нарастване е 0,89 %/год. или 0,69 вида/год. Заключава се, че

природозащитните усилия следва да бъдат насочени приоритетно към видовете от

категорията „Critically Endangered”.

Почти половината от видовете птици в Червения списък са терциерни реликти.

Плейстоценските реликти са осем пъти по-малко – едва 6,45 % от видовете. Сред тях

преобладават видовете, които обитават планинско-хълмистите ландшафти. Опазването

12

на глациалните реликти би имало по-значим успех, ако бъде насочено приоритетно в

планинските райони на страната.

Преобладаващата част от видовете са в 5 типа местообитания. Най-много (близо 1/3

или 31,6 %) от видовете са във влажните зони от вътрешността на страната. Във

влажните зони и горите се съхраняват над половината от застрашените видове птици в

България.

В новия Червен списък попадат видове от 23 зоогеографски типа. Това доказва, че

процесът на оредяване на птиците в страната е всеобхватен. Преобладаващата част от

видовете принадлежат към палеарктичния зоогеографски тип, представен с 48 вида,

следван от холарктичния, европейския, космополитния, туркестано-медитеранския и

Стария свят (представени с по 10-11 вида).

В България като цяло птиците са най-застрашени в сравнение с Гърция и Румъния.
