Follow the Swallow
No full textChack the blackbird and Apollo the swallow are fledgling friends. Apollo explains that he is practising flying to Africa - but Chack doesn't believe him. Chack tells Apollo that the blossom on his favourite tree will eventually turn into orange berries - Apollo doesn't believe him. But, with the inevitable turning of the seasons, both birds learn to believe the other - and cement their friendship forever. A delightful tale from the author of The Gruffalo - Julia Donaldson
Systematic notes on Asian birds. 31. Eastern races of the barn swallow Hirundo rustica Linnaeus, 1758
No full textThe types of two Far-eastern forms of barn swallow Hirundo rustica saturata Ridgway, 1883 and H. r. mandschurica Meise, 1934 are compared. A significant difference in the colour of the underparts is confirmed and the recognition of mandschurica is recommended

Studies on the management of the swallow bug, Oeciacus vicarius Horvath (Hemiptera: Cimicidae) and survival off its avian host
No full text2017 Spring.Includes bibliographical references.The swallow bug, Oeciacus vicarius Horvath is a common ectoparasite primarily associated with cliff swallows, Petrochelidon pyrrhonota (Vieillot). When the mud nests of the cliff swallows are constructed on homes and businesses, swallow bugs often readily enter attics or livable space after the host birds migrate and can cause serious episodes where they may bite humans. To better manage problem situations with swallow bugs a series of studies were conducted to determine the survival of swallow bugs in the absence of their avian host and to evaluate potential methods to monitor and control swallow bugs that do enter buildings. Swallow nests were collected in 2014 and 2015 immediately after nest abandonment and the nest contents sampled periodically for arthropods. Highest numbers of swallow bugs were found in the first sample dates, immediately after collection, averaging 269 swallow bugs/nest in 2014 and 297 swallow bugs/nest in 2015. Numbers of swallow bugs recovered declined sharply in later samples, with reductions at six months of 97.4% of the adults and 96.7% of the nymphs in the 2014 study, and reductions of 81.9% of the adults and 73.7% of the nymphs died in the 2015 study. At 12 months following collection, numbers of adults and nymphs had declined 99% and 98.3% in the 2014 study and 91.7% and 96.1% in the 2015 study. Other notable arthropods recovered from nests included the dermestid Trogoderma simplex Jayne, immature salticid spiders, and the bird flea Ceratophyllus petrochelidoni Wagner. Four traps were evaluated for their ability to capture swallow bugs in an arena test with an introduced swallow bug: a sticky card trap with no attractant (CatchMaster 288i), a carbon dioxide based trap with a collection cup (Bedbug Beacon), a carbon dioxide and heat trap with a bed bug pheromone on a sticky card (Biocare First Response Bed Bug Monitor), and a bed bug pheromone attractant trap with a collecting cup (SenSci Volcano). None of the traps containing attractants showed evidence that they were able to attract swallow bugs. The CatchMaster 288i and BedBug Beacon traps did work well as a passive monitoring device but both the Biocare First Response Monitor and SenSci Volcano SC caught few swallow bugs either because of trap design that allowed the insects to readily escape or prevented their capture due to poor adhesive properties of the glue. Follow-up studies were conducted to evaluate potential attractants in bioassay choice tests, including heat, carbon dioxide, and odors associated with swallow bugs. None of these traps showed evidence of attraction to swallow bugs, suggesting that swallow bugs may use different cues to located hosts than do bed bugs. Efficacies of insecticides for control of swallow bugs were tested in laboratory trials. Treatments included Suspend Polyzone (deltamethrin), Talstar Professional (bifenthrin), Onslaught Fastcap (esfenvalerate, prallethrin, piperonyl butoxide), Temprid (imidacloprid, cyfluthrin), and Phantom (chlorfenapyr). All of the pyrethroid containing insecticides showed good ability to kill swallow bugs, typically killing 100 percent of the test insects within one week. Lower mortality was observed with chlorfenapyr
AN EXPLORATION OF THE CULTURAL BELIEFS OF THE INDONESIAN AND CHINESE PEOPLE IN RELATION TO THE BUSINESS OF SWALLOW FARMING
No full textAbstract - This research is basic research that explores the public's trust in swallow farming business. Swiftlet nest is believed to have many benefits for health. Indonesia is the largest producer of swallow's nest in the world. Almost some of the swallow nest produced is exported abroad, especially to China. The purpose of this study is to discuss the reasons behind the belief that is expected to bring information to many people. So that people are able to think wisely and open in every business especially swiftlet nest business. While the method used by the author is qualitative methods by means of interviews, observation and analysis of documents in order to support the validity of the data. The main objects of the research are breeders, collectors and consumers of Swallow nest. The scope of this research is on cultural beliefs in Swallow farming based on Indonesia and China perpective. On the basis of the findings obtained during the study, researchers found that not all swallow nest businessmen believed in the belief. some of them might believe the impact of Swallow farming business but based on different reasons. It has been found not only from the Indonesian perpective but also in Chinese perpective

Shifting Border, Shifting Interpretation: what the Anglo-Norman Castle of Dodleston in Cheshire might be trying to tell us about the eleventh-century northern Anglo-Welsh Border
No full textThis chapter follows on from research and publication by this author on the form and placing of Anglo-Norman castles situated within the northern Anglo-Welsh medieval borderland, recently interpreted and newly termed the Irish Sea Cultural Zone (Swallow 2016). This interpretation argues for the Anglo-Normans’ reuse of pre-existing monuments dating from the prehistoric and Romano-British periods for the deliberate placing of their castle builds. Dodleston Castle was situated within the fluctuating borders of this frontier borderlands zone, and, it is argued, played a significant role in the continuity of strategic and commercial movement along the entirety of the Anglo-Welsh border and the Irish Sea Region. Within this context, and taking a cross-period and interdisciplinary research approach to re-examine the earthworks and landscape of Dodleston Castle in more detail than hitherto, the earthworks at Dodleston may reveal a meeting point of significance over millennia. It will be demonstrated, for instance, that Dodleston’s earthworks likely represent an Anglo-Saxon assembly site situated at the meeting points of important medieval administrative boundaries within the Irish Sea Cultural Zone. By considering the wider spatial significance of Dodleston beyond the temporal confines of the Anglo-Norman period, it is therefore possible to understand better, and reinterpret, the form of the castle earthworks as they exist in the landscape today
