| nest sanitation behavior in hirundines as a pre-adaptation to egg rejection to counter brood parasitism. | previous studies suggested that nest sanitation behavior may have been a pre-adaptation from which egg rejection of brood parasite eggs evolved. we tested this hypothesis in two swallow species, the red-rumped swallow (cecropis daurica) and the barn swallow (hirundo rustica). our results indicated that the red-rumped swallow, which is an accepter of foreign eggs, rejected a low percentage of non-egg-shaped objects and did so less often than the barn swallow, which is an intermediate rejecter of ... | 2015 | 25231538 |
| complete mitochondrial genome of red-rumped swallow, cecropis daurica (passeriformes: hirundinidae). | the complete mitochondrial genome of the cecropis daurica was determined by using a pcr-based method. the complete mitochondrial dna of this swallow was 17,949 bp in length, including 13 protein-coding genes, 2 ribosomal rna (rrna) genes, 22 transfer rna (trna) genes and 2 control regions. all genes were encoded on the heavy strain except for nd6 and eight trna genes. the gene arrangement of the cecropis daurica was similar to that found in other passerines. base composition of the heavy strain ... | 2016 | 24708115 |
| using dna barcodes to identify a bird involved in a birdstrike at a chinese airport. | one day at dusk in august, 200x, an airplane was struck by a bird at a chinese airport (m airport). after a careful check, some blades of the plane's engine were found to be out of shape and a few feathers and some bloodstains were found in the air intake of the engine. in order to know which species of bird was involved in the birdstrike, firstly we extracted dna from the bloodstains; secondly, the dna barcode (portion of coi gene) of the unknown species was amplified by pcr method; thirdly, se ... | 2010 | 20033492 |
| physiological and haematological consequences of a novel parasite on the red-rumped swallow hirundo daurica. | parasite virulence has been hypothesised to increase with the degree of host sociality because highly social hosts have a greater probability of encountering horizontal transmission of parasites and experiencing infections with multiple strains of the same parasites than do solitary hosts. as compared with the defences of closely related social host species, we predicted that solitary hosts should have relatively weak defences against parasites, thus being relatively more affected when parasitis ... | 2001 | 11513887 |
| mineralogical and textural characteristics of nest building geomaterials used by three sympatric mud-nesting hirundine species. | many hirundine species construct their nests by carrying mud particles from adjacent areas. this study aimed to investigate for the first time the materials that mud-nesting hirundines choose for nest construction from a mineralogical and sedimentological perspective. for this purpose, we sampled nests of three sympatric species, namely the barn swallow (hirundo rustica), the red-rumped swallow (cecropis daurica) and the house martin (delichon urbicum), from southeastern europe. our results show ... | 2018 | 30038225 |
| do swallows (hirundo daurica) use the visual cue of hatchling down-feathers to discriminate parasite alien nestlings? | egg recognition is a variable but common anti-parasitism defense among different species of birds with brood parasites. in contrast, nestling recognition is rare. very few studies have found nestling recognition in brood parasite hosts and determined the rejection mechanism behind this behavior. hosts may use the number of hatchling down-feathers to reject parasite nestlings. we tested whether hatchling down-feathers is a visual cue for the red-rumped swallow, a host that can recognize and rejec ... | 2020 | 32301245 |
