means A container you fill with seed and hang or mount outdoors so wild birds can eat from it conveniently and you can watch them.

from Straightforward compound of 'bird' and 'feeder' (one who or that which feeds). The practice of deliberately feeding wild birds took off as a hobby in the 19th and 20th centuries, and the devices evolved from simple scattered seed and homemade trays into the engineered, pest-resistant contraptions sold today — though 'pest-resistant' remains aspirational, as squirrels keep proving.
