Estimated richness and counts of birds by site in the three cities evaluated during the 18 years of the Christmas Count in Colombia.

Bogotá (a and d), Medellín (b and e), Cali (c and f). Left panels: species richness, right panels: individual count. Variation in annual estimates by location is represented by red dots. The dark blue line represents the mean of the estimate produced by the GLM, and the light blue areas are the 95% confidence intervals of the estimate. Sampling locations in Bogotá: Aurora Alta (AUA), Humedal de Córdoba-Parque Niza (HCOR), Humedal de Guaymaral (HGU), Humedal Jaboque (HJB), Humedal Juan Amarillo (HJA), Humedal la Conejera (HCON), Jardín Botánico (JBO), Parque La Florida (HPF), Parque Simón Bolívar (PSB), Santa María del Lago (HSL), Tabio (TBO), Valle de Teusacá (VTE). Sampling locations in Medellín: Cerro el Volador (CV), Jardín Botánico de Medellín (JB), Alto de San Sebastián (ASSE), Parque Ecológico La Romera (PER), Parque Ecológico Recreativo Alto de San Miguel (PERASM). Sampling locations in Cali: Chicoral-Dapa (CHIDA), Chicoral-Escuela (CHIES), Chicoral-Montebello (CHIMO), Kilómetro 18 (KM18).</p
