Little bustard (Tetrax tetrax L., 1758), is a large bird bustard family, the only member of the genus Tetrax. Nest in southern Europe , in Western and Central Asia, wintering occurs in the southern part of the range (

Isakov

, Flint 1987). Slide3

On nesting bustard arrives in late March - early April. In late October, little bustards gather in large flocks reaching 200 individuals in November and migrate to wintering grounds.Slide4

Objective To study the environmental characteristics of the population little bustard (Tetrax

tetrax

L., 1758) inhabiting the Saratov Zavolzh'ye.Slide5

General characteristics

The body size is not more than a hen. The body length of 42 to 45 cm wingspan not exceeding 90-110 cm, weight 500-900 g. body plumage is similar to the Great Bustard , but red tones in the plumage of a little muted. Top of sand -and-white plumage , as almost white

below. Slide6

General characteristics The main feature is the presence of males relatively symmetrical V-shaped white

collar.Slide7

General characteristicsFemales - inconspicuous, gray in color and is similar to the male in autumn plumage , but differs from it a bit

smaller.Slide8

General characteristics Usually

appears in the nest 3 - 5 eggs , occasionally there are 8 - 9 bright green with small yellowish

dots (Aksakov 1987).Slide10

General characteristics Bustard

prefers open habitats with grain agriculture, mainly on fallow

lands.Slide11

General characteristics Most of the diets of little bustards are large beetles, ground beetles. In addition to ground beetles are found in the same

Scarabaeus

and barbel.

Slide12

Conservation status

Over the past few decades have seen a strong decline in the number of species due to loss of habitat , as well as enhancing anthropogenic load on ecosystems , both in the wintering grounds and nesting sites , followed by displacement of habitat , as well as his break.Slide13

Conservation status

Species

listed in the IUCN Red List (

Tetrax

tetrax

Linnaeus, 1758) in Europe bustard has a status of vulnerable species and Near Threatened (IUCN, 2009).Slide14

Conservation statusMajor threats and limiting factors are (

1. Irrigation dry crops2 . Afforestation3 . Daylight perennial crops4 . Increasing the number of monocultures5 . Improper use of pesticidesSlide15

Distribution and abundance in Russia

In Russia bustard inhabit the Middle and Lower Volga , as well , there is evidence of his dwelling in the Orenburg region ( Barbazyuk

, 2006) and the Urals region( Borisenko , 2003). Previously mentioned meeting in the Ulyanovsk region , but now it seems to be completely gone in this region.Slide16

Distribution and abundance in Russia

Little bustard

- a typical representative of the avifauna cereals steppes in the Saratov region, a protected species, is presented in the Red List of the Saratov region. Slide17

Planned research

Planned number of the following studies to be conducted within the fieldwork at the biological station with

RAoS in Dyakovka

( Krasnokutsk district) :1) Investigation of the structure of vegetation in nesting places2 ) Assessment of prey nesting in places (the number of arthropods )3 ) Identification of the mating features 4) Evaluate the success of reproduction and limiting factors during the nesting

5 ) Identification of the timing of arrival and departure dates for the winter6) Estimated number of little bustard in the study area.Slide18

ResultsThe planned study will be conducted during the spring and autumn from 2014 to 2016.As a result, be possible to suggest ways to save the little bustard in Saratov

Zavolzh'ye
