Characterizing Avian Species Richness Patterns in Colorado

Abstract

Recently, many ecologists have focused their efforts on studying how urbanization impacts bird populations (Lee et al., 2021; Marques et al., 2020; Torres et al., 2016; Waltert et al., 2004). Urbanization and linear infrastructure (roads and power lines) can negatively affect bird population densities and avian species richness (total number of species at a site) (Benítez-López et al., 2010; Lee et al., 2021; Marques et al., 2020; Trammell & Bassett, 2012; Waltert et al., 2004). Studies have found that in areas with higher levels of urbanization, avian species richness (ASR) is lower (Lee et al., 2021; Waltert et al., 2004). Similarly, other studies show that major road density and proximity to linear infrastructure negatively affect ASR and overall abundance (BenítezLópez et al., 2010; Torres et al., 2016; Trammell & Bassett, 2012). Studying the relationship between ASR and proximity to linear infrastructure is incredibly important for informing decisions regarding the construction of new roads and power lines in areas with little human disturbance (Benítez-López et al., 2010; Marques et al., 2020; Torres et al., 2016; Trammell & Bassett, 2012).
