“…Because ecto‐ and endothermic organisms are affected differently by climate change, organisms at different trophic levels are not impacted similarly (Thackeray et al, ). Consistent with this suggestion, insect abundance has been closely related to current weather conditions (Kang & Kaller, ; Møller, , ; Teglhøj, ; Turner, ). Local insect availability increases with temperature and decreases with wind speed, cloud cover, and precipitation.…”

“…Third, I sampled insects on sticky plates (EcoStyle®) with a surface of 640 cm 2 during June 10–July 5 2017 by placing two traps within a 100 m radius of each barn swallow nest site since most foraging activities by barn swallows occur <200 m from the nest (Møller, , ; Turner, ). All insect plates were placed 1.5 m above ground, assuming that this is the most common foraging height for barn swallows (Bryant & Turner, ; Kang & Kaller, ; Møller, ; Teglhøj, ). The two individual insect sampling stations per nest allowed for statistical test of repeatability.…”

Farmers in most western countries have increased use of fertilizer and pesticides with impact on wild animals and plants, including the abundance of insects and their predators. I used 1,375 surveys of insects killed on car windscreens as a measure of insect abundance during 1997–2017 at two transects in Denmark. I cross‐validated this method against three other methods for sampling insect abundance, and I investigated the effects of this measure of insect abundance on the abundance of breeding insectivorous birds. The abundance of flying insects was quantified using a windscreen resulting in reductions of 80% and 97% at two transects of 1.2 km and 25 km, respectively, according to general additive mixed model. Insect abundance increased with time of day, temperature, and June date, but decreased with wind resulting in a reduction by 54%. The abundance of insects killed on a car windscreen was strongly positively correlated with the abundance of insects caught in sweep nets and on sticky plates in the same study areas and at the same time as when insects were sampled using windscreens. The decline in abundance of insects on windscreens predicted the rate at which barn swallows Hirundo rustica fed their nestlings, even when controlling statistically for time of day, weather, and age and number of nestlings. The abundance of breeding pairs of three species of aerially insectivorous birds was positively correlated with the abundance of insects killed on windscreens at the same time in the same study area. This suggests a link between two trophic levels as affected by the temporal reduction in the abundance of flying insects. These findings are consistent with recent dramatic declines in insect abundance in Europe and North America with consequences for the rate of food provisioning of barn swallow offspring, the abundance of aerially insectivorous birds and bottom‐up trophic cascades.

“…Therefore, the results of this study are not directly comparable with earlier studies which have used suction traps (Taylor , McCarty and Winkler ). Insect sampling was carried out from 15 June to 7 July, 2015 (first broods) and 1 August to 2 September, 2015 (second broods) by placing two individual sampling stations within a 100 m radius of each nest since most foraging activities occur less than 200 m from the nest (Bryant and Turner , , Kang and Kaller ). Each insect sampling station consisted of four yellow insect plates (EcoStyle ® ) with sticky surfaces and a total sampling area of 640 cm 2 .…”

A comparative study of insect abundance and reproductive success of barn swallows Hirundo rustica in two urban habitats

Few studies have quantified the relative reproductive success of passerines in urban habitats. I studied food availability and reproductive success of barn swallows Hirundo rustica in two urban habitats during 2012–2015. Barn swallows breeding in the town center experienced lower insect densities than those in the town periphery. Lower food availability resulted in reduced feeding rates per capita, lower nestling body mass, longer nestling periods, longer inter‐clutch intervals, fewer first and second brood fledglings and a lower total number of fledglings produced during the breeding season in comparison to barn swallows breeding in the town periphery. I hypothesize that the lower intra‐specific competition for nest sites and fitness advantages linked to the solitary breeding in urban habitats balanced the apparent costs of reproduction in more urbanized habitats.

Barn swallow (Hirundo rustica) is a migratory aerial-insectivorous bird and has been known to winter in Indonesia. Normally roost on trees, there was a report that thousands of them roosted on human-made building. The objective of this paper was to document the barn swallows that use an oil gathering station (GS) as their roosting site, examined their roosting habitat, and seek the reasons on why the GS was selected as the roosting habitat for the barn swallows. Observation was conducted in Petapahan GS, Riau, in May 2023. Swallow abundance was estimated in the evening (6:30-8:00pm), perching spots were observed. The land-use of surrounded area was observed. There were 4,000 barn swallows roosted at night in the GS. There were many big tanks, small-large pipes, handrails, valves, processing buildings that can be used for roosting. At night, the GS was bright and warm in most parts. The surrounding was a vast area of oil-palm plantation, mixed with mosaic microhabitats (agricultural area, open area, housing). Some possible reasons why swallows used GS were: (1) located at the migration route, (2) the abundance of perch sites, (3) warm temperatures, (4) sufficient lighting at night, (5) abundant insect food at the surrounding oil-palm.
