Capsule We found significant differences in the composition and diversity of diet among House Martins, Barn Swallows Swifts breeding same village Poland.Aims To evaluate character extent diversity, specialization overlap between trophically similar nestlings three species aerial feeding birds at location differing considerably foraging height.Methods Diet was determined based on faecal analysis. Differences food niche were assessed through multivariate analysis variance (manova), Shannon...
Abstract Developing protocols for threatened invertebrates is often challenging, because they are not only rare but also elusive. This the case with stag beetle ( Lucanus cervus ), a protected and flagship species saproxylic fauna in Europe. We applied standard transect walk at European scale (8 countries, 29 transects) to test its practicability reliability as survey design. A total of 533 sightings were recorded throughout sampling period, detection probability changed season progressed....
Farming activity severely impacts the invertebrate food resources of farmland birds, with direct mortality to populations above-ground arthropods thorough mechanical damage during crop harvests. In this study we assessed effects phenological periods, including timing harvest, on composition and biomass prey consumed by three species aerial insectivorous birds. Common Swifts Apus apus, Barn Swallows Hirundo rustica House Martins Delichon urbica breed sympatrically most their diet is obtained...
Abstract Analysis of faecal sacs nestling Barn Swallows Hirundo rustica from 52 breeding colonies located within fifteen spatially-separated villages in Poland has revealed that the basic component diet was Coleoptera (56.1% all identified prey items), followed by Hymenoptera (24.1%), Diptera (16.1%) and Hemiptera (3.3%). The average mass items with known weight amounted to 3.40 mg (95% CL, 3.16–3.63 mg; median=0.49 mg) dry weight. Coleopterans associated dung manure jointly made up 23.5%...
The role of granivorous birds as agents seed dispersal has been little explored and is poorly understood. We assessed the ability three species from a Central European agricultural landscape to disperse seeds dry-fruited plants. hypothesised that Grey Partridge Perdix perdix better disperser than either two buntings—Yellowhammer Emberiza citrinella Reed Bunting schoeniclus—in terms number intact recovered their droppings. droppings contained highest seeds. Surprisingly, however, per 1 g was...
Capsule The presence of farm animals increases the amount larger insect prey (mainly large Diptera and Coleoptera) decreases proportion smaller (Hymenoptera). Aims To determine relationships between diversity diet nestling Barn Swallows from 52 colonies located at sites with without livestock. Methods Diet was determined on basis faecal analysis. We used two approaches to quantify livestock based their spatial distribution – a breeding site-focused approach village-focused approach. Results...
The composition and quality of food provided to nestling birds influence their growth development offers key insight into the ecological requirements birds. One bird species whose feeding ecology is poorly understood Barred Warbler (Sylvia nisoria), which utilizes semi-natural shrubby vegetation in agroecosystems. Because nestlings vary greatly body mass we hypothesised that diet prey properties (size, diversity, taxonomic composition, chitin content resulting hardness digestibility) would...
Long-term studies on the ecological effects of continuous rye cultivations carried out in Poland are summarized. It was shown that cropping rye, despite decrease crop yields, no significant difference observed annual primary production rates compared with estimates found for fields cultivated diversified rotation patterns. In cultivation fauna impoverishment observed, while at same time number pests increased. The animal groups reduced by belong to Protozoa, Lumbricidae, Acarina, and winged...
Several studies have suggested dietary segregation between nestling and adult birds resulting from both requirements of offspring distance to the foraging sites. We examined diet in terms composition dimension, as weight, habitat taxonomy prey male female Bluethroats Luscinia svecica spp. cyanecula at a recently colonized area mosaic wetland (with sewage water) terrestrial habitats south-west Poland. On basis faecal samples collected 2009–2012 several broods 94 adults, we found that...
Diet of the Red-backed Shrike was analysed from collars in nestlings, pellets and prey remains larders. All material collected same territories Western Poland. A total 2855 items were identified all samples. Insects, mainly Coleoptera, Hymenoptera Orthoptera constituted 98.9% identified. To determine diet predict impact food sources on populations, three methods should be used together (pellet content analyses, collar sampling analysing larders). Our findings suggest that pellet analyses is...
Analyses of faeces the Black Redstart Phoenicurus ochruros from countryside south-western Poland revealed a significant increase in proportion plant items (mainly berries Sambucus nigralracemosa) between July and October; for animal prey an inverse trend was found. During summer-autumn, no trends mass all were The most numerous three genera ants (Lasius, Formica Myrmica; 44.1% by number prey). Large numbers undamaged seeds several species shrubs analyzed faeces, including non-native species,...

Abstract Whether Ca and other micronutrients are equally distributed in an avian eggshell over its longitudinal section what portion of these local resources utilized by developing embryos unanswered questions reproductive physiology. Here, we measured the thickness concentrations 16 chemical elements (Al, As, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Na, Ni, Pb, Se, Sr) 4 shell regions (sharp pole, equator, shoulder, blunt pole) White Stork (Ciconia ciconia) eggs representing different stages...
Abstract The role of frugivorous birds in dispersal the seeds fleshy-fruited plants is well understood, but other groups like granivores and omnivores can also act as vectors, especially process non-standard dispersal. In this study we examined two widely distributed (the Eurasian Blackbird, Turdus merula, Black Redstart, Phoenicurus ochruros) seed We analyzed content 279 droppings Redstart collected between July October 85 Blackbird during January. total found 366 seeds, representing 11...
Earthworms (Oligochaeta, Lumbricidae) form a significant component of the food web and are staple diet many higher‐trophic‐level predators, such as invertebrate‐feeding birds mammals. Their almost complete digestion in predator's gut hampers their detection or quantification faeces pellets except through labour‐intensive microscopic examination. As result, evaluation earthworms has been neglected most studies based on pellet analysis. We assess whether earthworm White Storks Ciconia ciconia...
