Nests are classified according to their age: new nests are those established for less than 1.5 years (triangles), while old nests are over 5 years old (circles). The color gradient indicates the square-rooted nest surface as a proxy for nest size. There is a strong positive correlation between nest surface and nest age (r = 0.61).
