Herons or brass wader birds

Nice pair of brass waders, herons it seems to me, probably dating from the 60s or 70s, with a surprising contrast between the stylized bodies with simple lines and the details in relief on the wings and bases. Brass, originally golden and shiny, has taken on a nice patina over the years. The base represents a leaf with raised veins. They are in good general condition but do not hide their age: a few points of blue corrosion, some small spots. They are 20 cm and 17 cm high. Their bases measure about 5.5 cm by 6 cm. The set weighs 240 g.
