Breeding habitat modelling of the Little Bustard Tetrax tetrax in the site of community importance of Cabrela (Portugal)

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 […]

Field identification of individual Little Bustard Tetrax tetrax males using plumage patterns.

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 […]

Habitat selection by territorial males of Little Bustard Tetrax tetrax in a NW Iberian population

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 […]

Density of the Little Bustard Tetrax tetrax in relation to agricultural intensification in central Spain

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 […]

Population size, phenology and habitat preferences of Little Bustard Tetrax tetrax in an isolated area of the northwestern Iberian Peninsula

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 […]

Habitat use and mating system of the houbara bustard ( Chlamydotis undulata undulata ) in a semi-desertic area of North Africa: implications for conservation

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

Population estimates of Houbara Bustard Chlamydotis undulata macqueenii in Punjab, Pakistan, november 1999

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 […]
