Frans Snyders, Concert of the Birds, n.d.

From the Museo del Prado:

Depictions of different types of birds perched on tree trunks, sometimes alongside a musical score, were made popular by Flemish artists during the early seventeenth century, especially Frans Snyders.

And, while these are generally considered allusions to the sense of hearing, that interpretation is not entirely clear. Others include the possibility that they represent wisdom through the presence of an owl, which embodies that concept and which often seems to be directing those bucolic concerts.

At any rate, the diversity of bird images makes this type of paintings an attractive manifestation of nature, making them collectors’ items for aristocrats and bourgeois, who often hung them in their country houses.
