Demography of tree swallows: explaining the contemporary decline of an aerial insectivore population.
Many species of birds have shown decline in abundance in North America. Most worrisome among them are aerial insectivores. For example, tree swallow (Tachycineta bicolor) abundance has declined by 4.2 % per year over the past 20 years in Québec. The goal of this project will be to expand a demographic model on tree swallow population dynamics, to integrate both local and global environment drivers and to quantify the relative role of these factors in driving the observed decline and forecast future population trends. The data available for this project come from a long-term individual monitoring of tree swallows in southern Québec, where survival and reproduction have been monitored in 400 nesting boxes since 2004.
