Bubulcus ibis ibis expanded its range by flying across the Atlantic Ocean from Africa or Europe to South America. To provide insights into the source of migrant birds, we genotyped cattle egret sampled in Central and southern Africa (N = 129, 13 sites, five countries) and Brazil (N = 166, six sites) at 14 microsatellites. Expected heterozygosity was high in all colonies, but significantly lower in Brazilian samples. Population-genetic analyses based on different assumptions concurrently found significant genetic differentiation between Brazil and Africa. The genetic homogeneity among African populations did not enable us to identify the source of the invasive birds. Among Brazilian populations, the highest proportion of the African allelic ancestry was found in Fernando de Noronha. This archipelago on the north-eastern coast of Brazil could be an important stopover site for migrating birds coming from Africa. Bayesian demographic analyses supported population growth in Africa with subsequent expansion to Brazil and migration from Africa to Brazil at the time of colonization. We discuss our findings in light of previous colonization trajectories suggested by meteorological models and the anthropogenic changes that may promote the expansion of the cattle egret in Brazil.

Bird censuses in Peru began in the early twentieth century with seabird censuses carried out by the Compañía Peruana del Guano and later by IMARPE. Between 1992 and 2016 annual censuses were carried out, in 61 wetlands, in 12 departments of Peru, recording a total of 151 species between resident and migratory. The censuses constitute a great contribution to the knowledge of waterbird species and to the synergies between institutions and ornithologists who, through volunteering, compile important information for species conservation and wetland management in the Andean slopes. The taxonomic composition of the species, the importance of censuses, the migration routes of birds from the Nearctic, southern and high Andean regions, and the protected areas in the conservation of wetlands and biodiversity are analyzed. The aim of this paper is to carry out a historical analysis of the censuses and their contribution to the knowledge of waterbirds carried out in the last three decades with special reference to the conservation of wetlands in the Andean slopes in Peru.
