The first photo was made by Carl Beel in Paramaribo in May 2011. The smaller picture was made by J.S. Dunning in Suriname. The bird was captured by me (Ribot) in Nickerie in 1982, when these finches had just recently invaded Suriname (probably just before 1980, acoording to local bird enthousiasts). By then, they were only known from the rice-fields in the west of Suriname and were coming from Guyana. In 1982 they were already numerous in Nickerie and had nests in grasslands and ricefields. In the year 2000 they were present in Wageningen (D.Fung), but they were also seen in the vicinity of Paramaribo (Weg naar Zee and even in Tourtonne, J. Luchmun). An expansion velocity of 250 km in 20 years. This is their sound (54 kB).
Each small square indicates the observation of at least one (group) of these birds, the medium ones at least 4 observations on different days and the largest ones 10 or more. The color of each square indicates: blue for coastal area, yellow for savanna and red for rainforest.The bird has been expanding its territory in Suriname in the last 20 years.
