Field Notes

These updates from our field biologists discuss the movements and activities of individual Florida panthers. Biologists use prefixes and numbers to identify each cat.

Panther Identification

When a kitten is handled at the den a transponder is inserted under the skin which permanently identifies that individual and it receives a "K" number. When a panther is captured and wears a radio collar it gets an "FP" number. FP just stands for Florida panther; they are numbered sequentially as they're captured. A panther that has never been handled at the den or captured for placement of a radio collar is identified as an uncollared Florida panther and has the designation "UCFP."
