We conducted a total of 225 bird counts in 24 sampling periods from March 2011 to March 2012 by using 5-min point counts with a fixed radius of 50 m in a systematic design (Buckland et al. 1993, Ralph et al. 1993). Four points were located in the woodland patch and five points in the surrounding herbaceous-shrub land, separated by 150 m each (Ralph et al. 1993). The same observer surveyed these nine points once every two weeks. We conducted point counts within the first four hours after sunrise. We recorded the species and number of all birds seen or heard during the 5-min sampling period (Ralph et al. 1993). We recorded birds that were flushed from within the 50-m radius upon the observers arrival as present (Ralph et al. 1993).” [Extracted from Palacio & Montalti, 2013]Citation(s)
