Figure 4. Seasonal occurrence of records of the Maguari Stork (Ciconia maguari) involving juveniles in the Pampa biome, in Rio Grande do Sul state, southern Brazil. Records were obtained by citizens and gathered in the WikiAves database in June 2020. Arabic numerals after each month represent 10-days long periods – (I):– days 1-10, (II): days 11-20, (III): days 21-31 of each month.
