JORDAN, Emilio A.; ROESLER, Ignacio  and  MOSCHIONE, Flavio N.. Distribución y estatus de la Garza Azul (Egretta caerulea) en Argentina. Hornero [online]. 2013, vol.28, n.1, pp.23-27. ISSN 0073-3407.

We analyzed all known records from Argentina of the Little Blue Heron (Egretta caerulea). We report the first breeding record and 13 new localities for the species, which is now known from 30 records from 28 localities in 10 provinces. Most records come from valleys and wetlands in northern and northwestern Argentina, where the species apparently breeds regularly. Individuals reported outside this area are mostly juveniles and seems to disperse through rivers such as the Pilcomayo, Bermejo, Paraná and de la Plata. The species is expanding its distribution southward in Argentina. Although similar, juveniles of the Little Blue Heron can be distinguished from adults of the Snowy Egret (Egretta thula) by differences in colour and shape of the bill, and colour of the facial bare skin, legs, and wing feathers.
