This Swallow is common near Mendoza, according to Prof. Burmeister.
White obtained it in May 1881 at Santo Tomé, Corrientes, and in 1882 at
Cosquin near Cordova. At Cosquin the first individual was seen on July
20th, but towards the end of August large numbers were observed, mostly
skimming over the river.
