Methods
Bird counts were conducted following a line-transect method (Bibby et al. 2000) from April 1985 to March 1986 and from April 2015 to March 2016 (two complete years; hereafter referred to as years 1985 and 2015, respectively). Ten transects of 200 m × 50 m (1 ha) separated by at least 250 m were established on streets, in which the species and the number of all birds seen or heard were recorded. The sampled area represented 4.3% out of the entire study area (10 ha out of 232 ha). The same observer (R.E.M.) sampled the 10 transects every month in both years (except for June 1985 and February 1986 owing to inclement weather), within the 4 h after sunrise and in good weather conditions (n = 100 and 120 counts in 1985 and 2015, respectively).” [Extracted from Palacio et al 2018]
