Siskin

The Lark sings as it flies in the air, the Quail sitting on the ground; others, on the boughs of trees, such as: the Canary, the Chaffinch, the Goldfinch, the Siskin, the Linner, the little Titmouse, the Woodwall, the Robin Redbreast, the Hedge Sparrow and so on.

I sat there on a bench in dappled shade, beside an aviary full of brightly feathered finches and siskins fluttering about.

Many of these classic methods are still used, with some modern improvements. For example, with the aid of special microphones and automated sound detection software, ornithologists recently reported […] that pine siskins (Spinus pinus) undergo an irregular, nomadic type of nocturnal migration.
