bird, captive, capture
禽 centers on a bird that is caught or kept: a captive bird, or the act of capturing. The bird sense is closely tied to the idea of being taken or held.
禽 is a pictograph of a net or trap for catching birds, later extended to mean the captured bird itself. The modern form retains a net-like top over a bird-like lower shape.
The top looks like a net or trap, and the bottom resembles a bird. Picture a bird caught under a net: 禽 is a captive bird or the act of capturing.
For キン, imagine a keen-eyed bird trapped under the net: keen -> キン, and the bird is captured.
