Summary

Analysis of biological tissues or direct sources of food may better characterize exposure of non-target organisms to current-use pesticides. Food boluses were collected from tree swallow (Tachycineta bicolor) nestlings using a non-lethal, ligature method and were composited based on nest. The ligatures, which prevented the bolus from being swallowed, were placed on nestlings for 1 h until samples were collected. Samples in 2016 were collected from nestlings at 6 days and 12 days post-hatch whereas 2018 samples were collected from nestlings at 12 days post-hatch. Furthermore, in 2016 and 2018, insects commonly consumed by tree swallows were collected via sweep net and composited based on suborder (Brachycera, Nematocera, Zygoptera, [...]

Purpose

Collected data were used to assess the exposure of tree swallows (Tachycineta bicolor) to current-use pesticides through their food sources. The data documents pesticide levels in food boluses collected directly from nestlings as well as insect prey. Data is part of a larger study aimed at understanding declines in aerial insectivores and farmland birds.
