Table 1. Summary of statistical analyses of lesser kestrel flight variables divided in two categories: Use of thermals and daily patterns.

Analysis Level Sampling frequency Response variables Meteorological predictors Other predictors
Use of thermals Commuting flight 1-second Number of thermals/distance, Accumulated ascent/distance, Total ascent/thermal event, Mean climb speed/thermal event Solar radiation Individual (Random), Commuting flight type
Use of thermals 6-hour intervals 1-second Number of thermals/distance, Accumulated ascent/distance, Total ascent/thermal event, Mean climb speed/thermal event Thermal uplift Date (Random)
Daily pattern of foraging flights Commuting flight All Maximum flight altitude, Cross-country speed Solar radiation Individual (Random), Commuting flight type, GPS sampling frequency
Daily pattern of foraging flights Foraging trip All Maximum distance from the colony, Duration Solar radiation Individual (Random), GPS sampling frequency, Colony, Colony*Solar Radiation
Daily pattern of foraging flights 6-hour intervals All Maximum flight altitude, Cross-country speed, Maximum distance from the colony, Duration Thermal uplift, Orographic uplift Date (Random), Colony, Colony*Thermal uplift

We analyzed these categories at different levels (commuting flights, foraging trips, or 6-hour intervals) registered at 1-second or at all (1-second to 10-minutes) sampling frequencies, depending on the category. We list the flight variables modeled at every level of analysis and the predictors tested in those models. Response variables used at the 6-hour interval level were mean values per interval.
