“…19 g). All three species make up a considerable percentage of the autumn-winter community of avian granivores feeding on/using crop fields in Europe (Moorcroft et al 2002;Orłowski 2006;Kasprzykowski and Goławski 2012), and their diets consist primarily of seeds of various arable weeds (Cramp 1998;Holland et al 2006;Orłowski and Czarnecka 2007;Orłowski et al 2011Orłowski et al , 2014. Therefore, an assessment of the contribution to ecosystem services provided by these birds, in the context of weed seed predation/dispersal or the seasonal depletion of seed resources as a result of consumption (sensu Pinowski and Wójcik 1968;Robinson and Sutherland 2000;Marone et al 2000;Holmes and Froud-Williams 2005), is highly desirable.…”

The role of granivorous birds as agents of seed dispersal has been little explored and is poorly understood. We assessed the ability of three species of birds from a Central European agricultural landscape to disperse seeds of dry-fruited plants. We hypothesised that Grey Partridge Perdix perdix is a better seed disperser than either of two species of buntings-Yellowhammer Emberiza citrinella and Reed Bunting Emberiza schoeniclus-in terms of the number of intact seeds recovered from their droppings. Partridge droppings contained the highest number of intact seeds. Surprisingly, however, the number of intact seeds per 1 g of droppings was the highest in Reed Bunting, smaller in Grey Partridge and the smallest in Yellowhammer. Our findings suggest that the passage of intact seeds of dryfruited plants through the digestive tract of seed-eating birds is most likely an effect of limited digestion, resulting from the intake of a large volume of seeds, a small part of which remains undigested. This effect could be magnified by the inclusion in the diet of some items of different digestibility (invertebrates or leaves). We suggest that non-standard dispersal of seeds with no adaptations to endozoochory by birds is a far more frequent and as yet under-appreciated phenomenon, which has potential ecological implications for the colonisation of new habitats/islands by plants. The ultimate elucidation of this process is extremely difficult and would require large sets of faeces to be examined.

“…For these reasons, many studies directed to the establishment of priority conservation areas have focused exclusively on breeding species distribution (Herrando et al, 2009;O'Dea et al, 2006;Virkkala and Rajasarkka, 2007). At local scales too, the majority of papers are focused on just one season, typically that for breeding (Berg, 2002;Santana et al, 2014;Wuczyński et al, 2011) or winter (Kasprzykowski and Goławski, 2012;Tryjanowski, 1995). Only a few studies have dealt with winter species distribution in order to evaluate the effectiveness or representation of conservation reserves (Chiatante and Meriggi, 2016;Gaston et al, 2008;Marfil-Daza et al, 2013).…”

Farmland landscapes are recognized as important ecosystems, not only for their rich biodiversity but equally so for the human beings who live and work in these places. However, biodiversity varies among sites (spatial change) and among seasons (temporal change). In this work, we tested the hypothesis that bird diversity hotspots distribution for breeding is congruent with bird diversity hotspots for wintering season, focusing also the representation of protected areas for the conservation of local hotspots. We proposed a framework based on the use of species richness, functional diversity, and evolutionary distinctiveness to characterize avian communities. Although our findings show that the spatial distribution of local bird hotspots differed slightly between seasons, the protected areas’ representation was similar in both seasons. Protected areas covered 65% of the most important zones for breeding and 71% for the wintering season in the farmland studied. Functional diversity showed similar patterns as did bird species richness, but this measure can be most effective for highlighting differences on bird community composition. Evolutionary distinctiveness was less congruent with species richness and functional diversity, among seasons. Our findings suggest that inter-seasonal spatial congruence of local hotspots can be considered as suitable areas upon which to concentrate greater conservation efforts. However, even considering the relative congruence of avian diversity metrics at a local spatial scale, simultaneous analysis of protected areas while inter-seasonally considering hotspots, can provide a more complete representation of ecosystems for assessing the conservation status and designating priority areas.

“…Later studies show that the basic autumn-winter diet of Yellowhammers was cereal seeds (Prys-Jones 1977, Cramp 1998, Glutz von Blotzheim 2001, Robinson 2004, Holland et al 2006. Recently, however, given the broad spectrum of habitats and the poor availability of cereal seeds on crop fields during the post-harvest period (reviewed in Wilson et al 1999, Donald et al 2001, Gibbons et al 2006, it can be assumed that Yellowhammers eat more seeds of wild plants or weeds, including some dicotyledonous weeds and/or wild grasses, especially in sites covered by permanent vegetation like fallow land, or stubble fields, which are the habitats of preference (Härdi 1989, Hancock & Wilson 2003, Gillings et al 2005, Orłowski 2006, Perkins et al 2008, Butler et al 2010, Goławski & Kasprzykowski 2010, 2011, Kasprzykowski & Goławski 2012, Goławski et al 2013.…”

“…The principal objective of this study was to determine the food niche of the Yellowhammer and to compare the composition and diversity of its winter diet in various contemporary farmland habitats (varying in intensity of agricultural activity) characteristic of lowland areas in Central Europe, which compose the main sites used by this species in winter (Orłowski 2006, Goławski & Dombrowski 2011, Goławski & Kasprzykowski 2010, 2011, Kasprzykowski & Goławski 2012. Our analysis determined the composition of the Yellowhammer's diet using both crop-free (=semi-natural) habitats with a permanent vegetation cover, and agricultural ones, including land-cover types under various tillage regimes, i.e.…”
