Major companies are planning reclamation strategies for mine tailings, in which wetlands will be used for the bioremediation of water and sediments contaminated with polycyclic aromatic hydrocarbons and naphthenic acids during the extraction process. A series of experimental wetlands were built on companies’ leases to assess the feasibility of this approach, and tree swallows (Tachycineta bicolor) were designated as upper trophic biological sentinels. From May to July 2004, prevalence and intensity of infestation with bird blow flies Protocalliphora spp. (Diptera: Calliphoridae) were measured in nests on oil sands reclaimed wetlands and compared with those on a reference site. Nestling growth and survival also were monitored. Prevalence of infestation was surprisingly high for a small cavity nester; 100% of the 38 nests examined were infested. Nests on wetlands containing oil sands waste materials harbored on average from 60% to 72% more blow fly larvae than those on the reference site. -

The Evolution of Nest Construction in Swallows (Hirundinidae) Is Associated with the Decrease of Clutch Size
© Biologiezentrum Linz/Austria; download unter www.biologiezentrum.at Linzer biol. Beitr. 38/1 711-716 21.7.2006 The evolution of nest construction in swallows (Hirundinidae) is associated with the decrease of clutch size P. HENEBERG A b s t r a c t : Variability of the nest construction in swallows (Hirundinidae) is more diverse than in other families of oscine birds. I compared the nest-building behaviour with pooled data of clutch size and overall hatching success for 20 species of swallows. The clutch size was significantly higher in temperate cavity-adopting swallow species than in species using other nesting modes including species breeding in evolutionarily advanced mud nests (P<0.05) except of the burrow-excavating Bank Swallow. Decrease of the clutch size during the evolution of nest construction is not compensated by the increase of the overall hatching success. K e y w o r d s : Hirundinidae, nest construction, clutch size, evolution Birds use distinct methods to avoid nest-predation: active nest defence, nest camouflage and concealment or sheltered nesting. While large and powerful species prefer active nest-defence, swallows and martins usually prefer construction of sheltered nests (LLOYD 2004). The nests of swallows vary from natural cavities in trees and rocks, to self-exca- vated burrows to mud retorts and cups attached to vertical faces. Much attention has been devoted to the importance of controlling for phylogeny in com- parative tests (HARVEY & PAGEL 1991), including molecular phylogenetic studies of swallows (WINKLER & SHELDON 1993). Interactions between the nest-construction va- riability and the clutch size, however, had been ignored. -

The Costs of Reproduction in Tree Swallows (Tachycineta Bicolor)L
2540 The costs of reproduction in tree swallows (Tachycineta bicolor)l NATHANIEL T. WHEELWRIGHT; JOANNA LEARY, AND CARAGH FITZGERALD Department of Biology, Bowdoin CIJ/lege,Brunswick. ME 04011, U.S.A. Received June 20, 1990 WHEELWRIGHT,N. T., LEARY, J., and FITZGERALD,C. 1991. The costs of reproduction in tree swallows (Tachycineta bicolor). Can. J. Zool. 69: 2540-2547. We investigated the effect of brood size on nestling growth and survival, parental survival, and future fecundity in tree swallows (Tach)cineta bicolor) over a 4-year period (1987 -1990) in an effort to understand whether reproductive trade-offs limit clutch size in birds. In addition to examining naturally varying brood sizes in a population on Kent Island, New Brunswick, Canada, we experimentally modified brood sizes, increasing or decreasing the reproductive burdens of females by two offspring. Unlike previous studies, broods of the same females were enlarged or reduced in up to 3 successive years in a search for evidence of cumulative costs of reproduction that might go undetected by a single brood manipulation. Neither observation nor experiment supported the existence of a trade-off between offspring quality and quantity, in contrast with the predictions of life-history theory. Nestling wing length, mass, and tarsus length were unrelated to brood size. Although differences between means were in the direction predicted, few differences were statistically significant, despite large sample sizes.~estlings from small broods were no more likely to return as breeding adults than nestlings from large broods, but return rates of both groups were very low. Parental return rates were also independent of brood size, and there was no evidence of a negati ve effect of brood size on future fecundity (laying date, clutch size). -
Breeding Biology of Asian House Martin Delichon Dasypus in a High-Elevation Area
FORKTAIL 28 (2012): 62–66 Breeding biology of Asian House Martin Delichon dasypus in a high-elevation area ZHIXIN ZHOU, YUE SUN, LU DONG, CANWEI XIA, HUW LLOYD & YANYUN ZHANG We present data on the breeding biology of the largest known colony of Asian House Martin Delichon dasypus, located in the Jiangxi Wuyishan Nature Reserve at 2,158 m in the Huanggang Mountains, China. Nest surveys conducted in abandoned buildings in a subalpine meadow during March–August 2007 and 2008 yielded 163 and 132 clutches, from 84 and 82 nests, respectively. Breeding pairs also laid multiple broods and replacement clutches. Average clutch size was 3.0 and 2.6 eggs for first and second broods respectively. Synchronous hatching was detected in 79% of clutches. The proportion of eggs hatching was 0.7 and 0.6 for first and second broods respectively, and the proportion fledging was 0.5 and 0.4 respectively. Nests situated inside buildings were more successful than those situated outside owing to greater protection from severe weather, which was the major cause of breeding failure. Nest losses caused by severe weather were more pronounced later in the breeding season. INTRODUCTION Nest surveys The 3-ha study area is predominately subalpine meadow habitat in Many bird species raise only one brood per year because of a narrow which are situated more than 30 abandoned buildings and garages period of suitable environmental conditions which prohibits that provide suitable nesting substrate for the breeding martins.

TREE SWALLOW Tachycineta Bicolor Tree Swallows Are the Only Swallows to Be Seen All Year in the Sacramento Region
TREE SWALLOW Tachycineta bicolor Tree swallows are the only swallows to be seen all year in the Sacramento region. A few winter here; others come to join them early in the spring. They are about sparrow-length but slimmer. The male is steel blue on top, white underneath. Tree swallows like wooded areas near streams. They can be seen skimming close to the water scooping up insects. Usually a hole in a tree trunk is chosen for a nest and lined with grass, leaves and feathers. The violet green swallow, a bird with similar colors but with white around the sides of the rump, is found here in warm weather. CLIFF SWALLOW Petrochelidon pyrrhonota Cliff swallows, famous for their annual return to San Juan Capistrano, likewise return to the Sacramento region within a few days of the same date each year. Wherever a bridge or culvert houses a colony of these swallows, the same kind of homecoming takes place each spring. Cliff swallows are identified by their buff foreheads, orange rumps, and square tails. They fly with long sweeping glides and steep climbs, catching flying insects on the wing. The bulb-shaped nests, hung under bridges, highway overpasses and eaves of buildings, are built entirely of mud. Flocks of cliff swallows can be seen around puddles gathering mud in their bills. When disturbed by an intruder or when flying over feeding grounds, the birds utter a squeaky, guttural sound. BARN SWALLOW Hirundo rustica Here is a bird with a real “swallow tail” outfit. In fact, it is our only swallow with a deeply forked tail. -
Effect of Gravel Roads on Tree Swallow (Tachycineta Bicolor) Nesting Success in Beaverhill
Effect of Gravel Roads on Tree Swallow (Tachycineta bicolor) Nesting Success in Beaverhill Natural Area, Alberta ABSTRACT Roads, which are essential for modern transportation, have the potential to disrupt bird reproduction. Collisions with vehicles are a huge source of bird mortalities and result in nest abandonment. As well, vehicles introduce pollutants into the environment which may alter survival of nestlings. Therefore, roads may alter the fitness of adult birds by affecting their clutch size or fledging success. Tree swallows (Tachycineta bicolor) are a passerine on which the effects of contaminants are often studied; however, little is known about the influence of roads and vehicles on this species. This study aimed to determine the effect of a gravel road on the reproductive success of tree swallows using nest boxes near Beaverhill Natural Area, Alberta. The clutch size and number of fledglings were recorded from May to August and were used to compare success of swallows nesting along a gravel road to in the natural area. While tree swallows showed a preference for nesting in the natural area, nesting along the road had no effect on clutch size or fledgling success. This suggests that, while the road may not be ideal nesting conditions, it does not appear to negatively affect reproductive output. More research should be completed, however, to determine whether roads affect different aspects of reproduction, such as the health of the nestlings or their survival after fledging. INTRODUCTION Human infrastructures create environmental disturbances that can negatively impact many animals, including birds. In developed areas, roads, arguably one of most detrimental infrastructures to wildlife, form a huge network that fragments the landscape, and can cause changes in bird behavior, biology and reproduction. -
The First Record of Common House-Martin (Delichon Urbicum) for British Columbia. by Rick Toochin, Peter Hamel, Margo Hearne and Martin Williams
The First Record of Common House-Martin (Delichon urbicum) for British Columbia. By Rick Toochin, Peter Hamel, Margo Hearne and Martin Williams. Introduction and Distribution The Common House-Martin (Delichon urbicum) is a small passerine found in the Old World from Europe and Asia. There are 2 subspecies and most size differences between north and southern populations are clinal (Turner and Rose 1989). In Europe, the nominate subspecies (D. u. urbicum) is found breeding from Great Britain, to Russia, also in North Africa and across the Mediterranean Sea to Turkey and Israel and further east to central Asia (Mullarney and Zetterstrom 2009). This subspecies of the Common House-Martin winters throughout west and southeast Africa (Mullarney and Zetterstrom 2009). In Far East Asia, the subspecies (D. u. lagopodum) of Common-House Martin is a widespread breeding species from the Yenisei to North-east China, North-east Russia, Yakutia, Chukotka, north Koryakia coast and possibly in Kamchatka (Brazil 2009). The Common House-Martin is a rare migrant in Japan and Korea (Brazil 2009). This subspecies does winter in small numbers in South Eastern China, but the bulk of the population winters in Southeast Asia (Brazil 2009). In North America, the Common House-Martin is an accidental to casual vagrant (Dunn and Alderfer 2011). In Alaska, there is one specimen record of the Common House-Martin which belongs to the Asian subspecies (D. u. lagopodum), which is assumed to be the rest of the observations in Alaska, and this species is classified as casual with scattered records from Nome, St. Paul Island, Gambell, Buldir Island, St. -
