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 […]
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 […]
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 […]
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 […]
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 […]
Evidence of prenuptial moult in the Little Bittern Ixobrychus minutus
Little Bittern (Ixobrychus minutus) Science Article 1 abstract Evidence for a partial prenuptial moult in the Little Bittern Ixobrychus minutus is reported for the first time, and is based on both live and museum specimens. The prenuptial moult, which is probably undertaken in the African winter quarters shortly before the spring migration, involves body feathers […]

Sex differences in Little Auk Alle alle parental care: transition from biparental to paternal-only care
Little Auk (Alle alle) Science Article 1 abstract Understanding differences in male and female care in biparental care systems can help interpret the selective pressures that shape parental strategies. We examined Little Auk Alle alle parental care at a breeding colony during the chick-rearing and fledging periods by conducting observations on marked, known-sex pairs, and […]
