Little Bustard (Tetrax tetrax) Science Article 1 abstract We examine the variability in phenotypic characteristics in Little Bustard Tetrax tetrax males to determine which are the elements that better allow individual recognition throughout a season. Six variables were chosen, for which individual variations could be classed into clearly distinguishable categories and for which all categories […]

Little Bustard (Tetrax tetrax) Science Article 5 abstract The galician population of Little Bustard Tetrax tetrax occupies a marginal area within the Iberian distribution range of the species, and up to the present day it has received little attention. The general pattern of habitat selection of territorial males in the A Limia region (Galicia, NW […]

Little Bustard (Tetrax tetrax) Science Article 2 abstract […]. From a landscape point of view, the effect of agricultural intensification is the creation of a much simpler habitat due to the disappearance of minor crops in favour of cereal crops, a decrease in medium- and long-fallow land, an increase in size of landholdings, the removal […]

Little Bustard (Tetrax tetrax) Science Article 4 abstract The main summer populations of Little Bustard in Galicia occur in the districts of A Limia,Ourense (Villarino et al., 2002) and Terracha, Lugo (Barcena et al., 1987). These two populations are the only ones on the Iberian Peninsula within the Eurosiberian region. Data on these marginal populations […]

Little Bustard (Tetrax tetrax) Science Article 3 abstract Aims: The Little Bustard often occurs in fragmented open landscapes in southwest Portugal, where agricultural fields are spaced with forest stands and shrublands. In these areas species abundances and distribution patterns are poorly known, and there is almost no information about the effects of human activities on […]

Houbara Bustard (Chlamydotis undulata) Science Article 2 abstract Studies of the movements and home-ranges of houbara bustards (Chlamydotis undulata undulata) showed sexual and seasonal differences in the use of space, with a polygynous mating system similar to an

Houbara Bustard (Chlamydotis undulata) Science Article 4 abstract Houbara Bustard Chlamydotis undulata macqueenii is reportedly declining rapidly in all the range states and its population believed to be much less now than some 10-12 years ago (Goriup, 1997). Rough estimates of the declining rates from causal observations in different parts of Balochistan indicate a declining […]

Houbara Bustard (Chlamydotis undulata) Science Article 1 abstract In order to define the features that determine breeding habitat suitability forthe Houbara Bustard (Chlamydotis undulata macqueenii), a study of nest-site selection by this species was carriedout in Mori, Xinjiang, China during the breeding seasons in April-June 1998-2000. Most habitats chosenfor nest sites were open areas with […]

Houbara Bustard (Chlamydotis undulata) Science Article 3 abstract Human activities have been reported to impinge on the distribution of the endangered Houbara Bustard Chlamydotis undulata undulata. The present study intends to investigate spatial relationships between Bustard and pastoral distribution in order to identify avoidance patterns and potential exclusions of the species from still-suitable grounds.The study […]

Great Bustard (Otis tarda) Science Article 2 abstract Between 1998 and 2002 we carried out five spring censuses of the Great Bustard population of Madrid region. The average count was 1148 individuals (337 males and 811 females) distributed in 13 leks. The species
