Table 2.

Nest box occupancy by American kestrels among sampling areas (Parque Luro Natural Reserve, Traditional farmland and, Intensive farmland) between 2011 and 2016 in La Pampa, central Argentina. Nest boxes in intensive agricultural areas were placed in the year 2012. The number of nest boxes provided in each area is indicated in brackets. Given that some nest boxes were stolen or got broken through the different years, we replaced them, however, it generated a slight variation in the final number of nest boxes monitored each year in the different areas.
