They were driven at low speeds (less than 20 km/h) during the cooler periods of the day (early morning and late afternoon). frequent stopping points were made in places with good visibility to locate the birds. All detections of the species were noted in a field form specifically made for this purpose. These forms included (a) the location (with geographic coordinates), time, number of individuals, sex, age (classifying each animal as Immature, Juvenile, Sub-adult or Adult), number of offspring per female, behaviour and habitat of occurrence. Additionaly, the following metadata were included: (a) day of the visit, start and end time of the transect, observer identification, weather conditions in qualitative scales (cloud cover, temperature wind and rainfall. In the spring, the probability of breeding was also included, according to a numeric code, aggregated into three possibilities: “no confirmed breeding” (0), “possible breeding” (1-3), probable breeding (4-10) and confirmed breeding (11-16) (Equipa Atlas, 2008).
